Driving and Operating
Electric Power Steering
Control of a Vehicle
Steering
The vehicle is equipped with an electric
power steering system, which reduces the
amount of effort needed to steer the
vehicle. It does not have power steering
fluid. Regular maintenance is not required.
Braking, steering, and accelerating are
important factors in helping to control a
vehicle while driving.
Caution
To avoid damage to the steering system,
do not drive over curbs, parking barriers,
or similar objects at speeds greater than
3 km/h (1 mph). Use care when driving
over other objects such as lane dividers
and speed bumps. Damage caused by
misuse of the vehicle is not covered by
the vehicle warranty.
Braking
If the vehicle experiences a system
malfunction and loses power steering,
greater steering effort may be required.
Power steering assist also may be reduced if
you turn the steering wheel as far as it can
turn and hold it there with force for an
extended period of time.
Braking action involves perception time and
reaction time. Deciding to push the brake
pedal is perception time. Actually doing it is
reaction time.
Average driver reaction time is about
three-quarters of a second. In that time, a
vehicle moving at 100 km/h (60 mph) travels
20 m (66 ft), which could be a lot of
distance in an emergency.
See your dealer if there is a problem.
Curve Tips
Helpful braking tips to keep in mind include:
.
.
.
Take curves at a reasonable speed.
Reduce speed before entering a curve.
Maintain a reasonable steady speed
through the curve.
.
Keep enough distance between you and
the vehicle in front of you.
.
.
Avoid needless heavy braking.
Keep pace with traffic.
.
Wait until the vehicle is out of the curve
before accelerating gently into the
straightaway.
If the engine ever stops or a brake fault
occurs, the brakes may lose power assist.
More effort will be required to stop the
vehicle. It may take longer to stop.
Steering in Emergencies
.
There are some situations when steering
around a problem may be more effective
than braking.
Driving and Operating

.
.
.
Slow down and adjust your driving
Holding both sides of the steering wheel
allows you to turn 180 degrees without
removing a hand.
The Antilock Brake System (ABS) allows
steering while braking.
2. Turn the steering wheel about
one-eighth of a turn, until the right front
tire contacts the pavement edge.
according to weather conditions. Stopping
distance can be longer and vehicle control
can be affected when traction is reduced
by water, snow, ice, gravel, or other
material on the road. Learn to recognize
warning clues — such as enough water,
ice, or packed snow on the road to make
a mirrored surface — and slow down
when you have any doubt.
3. Turn the steering wheel to go straight
down the roadway.
Off-Road Recovery
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three control
systems:
.
Try to avoid sudden steering, acceleration,
or braking, including reducing vehicle
speed by shifting to a lower gear. Any
sudden changes could cause the tires to
slide.
.
Braking Skid — wheels are not rolling.
.
Steering or Cornering Skid — too much
speed or steering in a curve causes tires
to slip and lose cornering force.
Remember: Antilock brakes help avoid only
the braking skid.
.
Acceleration Skid — too much throttle
causes the driving wheels to spin.
Off-Road Driving
Defensive drivers avoid most skids by taking
reasonable care suited to existing conditions,
and by not overdriving those conditions. But
skids are always possible.
Four-wheel-drive vehicles can be used for
off-road driving. Vehicles without four-wheel
drive and vehicles not equipped with All
Terrain (AT) or On-Off Road (OOR) tires must
not be driven off-road except on a level,
solid surface. For contact information about
the original equipment tires, see the
warranty manual.
The vehicle's right wheels can drop off the
edge of a road onto the shoulder while
driving. Follow these tips:
1. Ease off the accelerator and then,
if there is nothing in the way, steer the
vehicle so that it straddles the edge of
the pavement.
If the vehicle starts to slide, follow these
suggestions:
Ease your foot off the accelerator pedal
and steer the way you want the vehicle
to go. The vehicle may straighten out. Be
ready for a second skid if it occurs.
.
One of the best ways for successful off-road
driving is to control the speed.

Driving and Operating
For more information about loading the
vehicle, see Vehicle Load Limits 0 204 and
Tires 0 369.
Caution
Warning
{
Operating the vehicle for extended
periods without the front fascia lower air
dam installed can cause improper airflow
to the engine. Reattach the front fascia
air dam after off-road driving.
When driving off-road, bouncing and
quick changes in direction can easily
throw you out of position. This could
cause you to lose control and crash. You
and your passengers should always wear
seat belts.
Environmental Concerns
.
Always use established trails, roads, and
areas that have been set aside for public
off-road recreational driving and obey all
posted regulations.
Loading the Vehicle for Off-Road Driving
.
.
Do not damage shrubs, flowers, trees,
or grasses or disturb wildlife.
Do not park over things that burn. See
Before Driving Off-Road
Have all necessary maintenance and
service work completed.
Fuel the vehicle, fill fluid levels, and check
inflation pressure in all tires, including the
spare, if equipped.
Warning
{
.
.
Unsecured cargo on the load floor can
be tossed about when driving over
rough terrain. You or your passengers
can be struck by flying objects. Secure
the cargo properly.

Driving on Hills
Driving safely on hills requires good
judgment and an understanding of what the
vehicle can and cannot do.
.
.
Read all the information about
four-wheel-drive vehicles in this manual.
.
.
Keep cargo in the cargo area as far
forward and as low as possible. The
heaviest things should be on the floor,
forward of the rear axle.
Remove any underbody air deflector,
if equipped. Re-attach the air deflector
after off-road driving.
Know the local laws that apply to off-road
driving.
Warning
{
Many hills are simply too steep for any
vehicle. Driving up hills can cause the
vehicle to stall. Driving down hills can
cause loss of control. Driving across hills
can cause a rollover. You could be injured
or killed. Do not drive on steep hills.
Heavy loads on the roof raise the
vehicle's center of gravity, making it
more likely to roll over. You can be
seriously or fatally injured if the
vehicle rolls over. Put heavy loads
inside the cargo area, not on the roof.
.
To gain more ground clearance if needed, it
may be necessary to remove the front fascia
lower air dam, if equipped. However, driving
without the air dam reduces fuel economy.
Driving and Operating
199
.
.
.
Avoid turns that take the vehicle across
the incline of the hill. Driving across an
incline puts more weight on the downhill
wheels, which could cause a downhill
slide or a rollover.
Loose gravel, muddy spots, or even wet
grass can cause the tires to slip sideways,
downhill. If the vehicle slips sideways, it
can hit something and potentially
roll over.
Hidden obstacles can make the steepness
of the incline more severe. If a rock is
driven across with the uphill wheels, or if
the downhill wheels drop into a rut or
depression, the vehicle can tilt even more.
Before driving on a hill, assess the
steepness, traction, and obstructions. If the
terrain ahead cannot be seen, get out of the
vehicle and walk the hill before driving
further.
Warning
{
If the vehicle has the two-speed
automatic transfer case, shifting the
transfer case to N (Neutral) can cause
your vehicle to roll even if the
transmission is in P (Park). This is because
the N (Neutral) position on the transfer
case overrides the transmission. You or
someone else could be injured. If leaving
the vehicle, set the parking brake and
shift the transmission to P (Park). Shift
the transfer case to any position but
N (Neutral).
When driving on hills:
.
Use a low gear and keep a firm grip on
the steering wheel.
.
.
Maintain a slow speed.
When possible, drive straight up or down
the hill.
.
Slow down when approaching the top of
the hill.
Warning
{
.
.
.
If an incline must be driven across, and
the vehicle starts to slide, turn downhill.
This should help straighten out the
vehicle and prevent the side slipping.
Never go downhill forward or backward
with either the transmission or transfer
case in N (Neutral). The brakes could
overheat and you could lose control.
When driving down a hill, keep the
vehicle headed straight down. Use a low
gear because the engine will work with
the brakes to slow the vehicle and help
keep the vehicle under control.
Driving to the top of a hill at high speed
can cause a crash. There could be a
drop-off, embankment, cliff, or even
another vehicle. You could be seriously
injured or killed. As you near the top of a
hill, slow down and stay alert.
Warning
{
Heavy braking when going down a hill
can cause your brakes to overheat and
fade. This could cause loss of control and
you or others could be injured or killed.
Apply the brakes lightly when descending
a hill and use a low gear to keep vehicle
speed under control.
.
Use headlamps even during the day to
make the vehicle more visible.
If a brake fade condition is detected, a DIC
warning message is displayed. Adjust brake
pedal use and shift to a lower transmission
gear to reduce braking.
200
Driving and Operating
.
If driving downhill when the vehicle
stalls, shift to a lower gear, release
the parking brake, and drive straight
down the hill.
If the brakes continue to fade to a severe
condition, additional DIC messages are
displayed. The brake system warning light
will illuminate, and the vehicle speed may
be limited. See Brake System Warning Light
0 119.
This affects steering, accelerating, and
braking. Drive at a reduced speed and avoid
sharp turns or abrupt maneuvers.
Traction is reduced on hard packed snow
and ice and it is easy to lose control. Reduce
vehicle speed when driving on hard packed
snow and ice.
3. If the vehicle cannot be restarted after
stalling, set the parking brake, shift into
P (Park), and turn the vehicle off.
If the vehicle stalls on a hill:
3.1. Leave the vehicle and seek help.
1. Apply the brakes to stop the vehicle, and
then apply the parking brake.
Warning
{
3.2. Stay clear of the path the vehicle
would take if it rolled downhill.
Driving on frozen lakes, ponds, or rivers
can be dangerous. Ice conditions vary
greatly and the vehicle could fall through
the ice; you and your passengers could
drown. Drive your vehicle on safe
surfaces only.
2. Shift into P (Park) and then restart the
engine.
Warning
{

If driving uphill when the vehicle
stalls, shift to R (Reverse), release the
parking brake, and back

downhill side when stopped across an
incline is dangerous. If the vehicle rolls
over, you could be crushed or killed.
Always get out on the uphill side of the
vehicle and stay well clear of the
rollover path.
straight down.
.
Never try to turn the vehicle around.
If the hill is steep enough to stall the
vehicle, it is steep enough to cause it
to roll over.
Driving in Water
Warning
{
.
.
If you cannot make it up the hill,
back straight down the hill.
Never back down a hill in N (Neutral)
using only the brake. The vehicle can
roll backward quickly and you could
lose control.
Driving through rushing water can be
dangerous. Deep water can sweep your
vehicle downstream and you and your
passengers could drown. If it is only
shallow water, it can still wash away the
ground from under your tires. Traction
could be lost, and the vehicle could roll
over. Do not drive through rushing water.
Driving in Mud, Sand, Snow, or Ice
Use a low gear when driving in mud — the
deeper the mud, the lower the gear. Keep
the vehicle moving to avoid getting stuck.
Traction changes when driving on sand. On
loose sand, such as on beaches or sand
dunes, the tires tend to sink into the sand.

exhaust system for damage and check the
fuel lines and cooling system for any
leakage.
Caution
Do not drive through standing water if it
is deep enough to cover the wheel hubs,
axles, or exhaust pipe. Deep water can
damage the axle and other vehicle parts.
Flowing or rushing water creates strong
forces. Driving through flowing water
could cause the vehicle to be carried
away. If this happens, you and other
vehicle occupants could drown. Do not
ignore police warnings and be very
cautious about trying to drive through
flowing water.
More frequent maintenance service is
required. See the Maintenance Schedule
0 417.
If the standing water is not too deep, drive
through it slowly. At faster speeds, water
can get into the engine and cause it to stall.
Stalling can occur if the exhaust pipe is
under water. Do not turn off the ignition
when driving through water. If the exhaust
pipe is under water, the engine will not
start. When going through water, the brakes
get wet and it may take longer to stop. See
“Driving on Wet Roads” later in this section.
Driving on Wet Roads
Rain and wet roads can reduce vehicle
traction and affect your ability to stop and
accelerate. Always drive slower in these
types of driving conditions and avoid driving
through large puddles and deep-standing or
flowing water.
Hydroplaning
Hydroplaning is dangerous. Water can build
up under the vehicle's tires so they actually
ride on the water. This can happen if the
road is wet enough and you are going fast
enough. When the vehicle is hydroplaning, it
has little or no contact with the road.
Warning
{
Wet brakes can cause crashes. They
might not work as well in a quick stop
and could cause pulling to one side. You
could lose control of the vehicle.
After Off-Road Driving
Remove any brush or debris that has
collected on the underbody or chassis,
or under the hood. These accumulations can
be a fire hazard. Reinstall underbody air
deflector and air dam if removed.
There is no hard and fast rule about
hydroplaning. The best advice is to slow
down when the road is wet.
After driving through a large puddle of
water or a car/vehicle wash, lightly apply
the brake pedal until the brakes work
normally.
Other Rainy Weather Tips
After operation in mud or sand, have the
brake linings cleaned and checked. These
substances can cause glazing and uneven
braking. Check the body structure, driveline,
steering, suspension, wheels, tires, and
Besides slowing down, other wet weather
driving tips include:

Keep windshield wiping equipment in
good shape.
Keep the windshield washer fluid reservoir
filled.
Have good tires with proper tread depth.
See Tires 0 369.
Snow or ice between the tires and the road
creates less traction or grip, so drive
carefully. Wet ice can occur at about 0 °C
(32 °F) when freezing rain begins to fall.
Avoid driving on wet ice or in freezing rain
until roads can be treated.
Warning
{
Coasting downhill in N (Neutral) or with
the ignition off is dangerous. This can
cause overheating of the brakes and loss
of steering assist. Always have the engine
running and the vehicle in gear.
For Slippery Road Driving:
Turn off cruise control.
.
Accelerate gently. Accelerating too quickly
causes the wheels to spin and makes the
surface under the tires slick.
Turn on Traction Control. See Traction
Control/Electronic Stability Control 0 237.
.
Drive at speeds that keep the vehicle in
its own lane. Do not swing wide or cross
the center line.
Be alert on top of hills; something could
be in your lane (e.g., stalled car, crash).
Pay attention to special road signs (e.g.,
falling rocks area, winding roads, long
grades, passing or no-passing zones) and
take appropriate action.
Hill and Mountain Roads
Driving on steep hills or through mountains
is different than driving on flat or rolling
terrain. Tips include:
.
.
.
.
.
The Antilock Brake System (ABS) improves
vehicle stability during hard stops, but
the brakes should be applied sooner than
when on dry pavement. See Antilock
Brake System (ABS) 0 235.
Allow greater following distance and
watch for slippery spots. Icy patches can
occur on otherwise clear roads in shaded
areas. The surface of a curve or an
overpass can remain icy when the
surrounding roads are clear. Avoid sudden
steering maneuvers and braking while
on ice.
Keep the vehicle serviced and in good
shape.

Check all fluid levels and brakes, tires, and
cooling system.
Shift to a lower gear when going down
steep or long hills.

For information about using tire chains on
the vehicle, see Tire Chains 0 387.
If equipped, there are recovery hooks at the
front of the vehicle. Use them if the vehicle
is stuck off-road and needs to be pulled
some place to continue driving.
Recovery Hooks

Rocking the Vehicle to Get It Out
Never pull on recovery hooks from the
side. The hooks could break and you and
others could be injured. When using
recovery hooks, always pull the vehicle
from the front.
Caution
Vehicle Load Limits
Do not hold the steering wheel at full
rotation for more than 15 seconds and/or
at an elevated RPM. Damage may occur
to the power steering system and there
may be loss of power steering assist.
It is very important to know how much
weight the vehicle can carry. This
weight is called the vehicle capacity
weight and includes the weight of all
occupants, cargo, and all
nonfactory-installed options. Two labels
on the vehicle may show how much
weight it was designed to carry: the
Tire and Loading Information label and
the Certification/Tire label.
Turn the steering wheel left and right to
clear the area around the front wheels. Then
make sure the wheels are pointed straight
ahead. For four-wheel-drive vehicles, shift
into Four-Wheel Drive High. Turn the TCS
off. Shift back and forth between R (Reverse)
and a forward gear, spinning the wheels as
little as possible. To prevent transmission
wear, wait until the wheels stop spinning
before shifting gears. Slowly spinning the
wheels in the forward and reverse directions
causes a rocking motion that could free the
vehicle. If that does not get the vehicle out
after a few tries, it might need to be towed
out. See Transporting a Disabled Vehicle
0 402. Recovery hooks can be used, if the
vehicle has them.
Warning
{
Do not load the vehicle any heavier
than the Gross Vehicle Weight Rating
(GVWR), or either the maximum
front or rear Gross Axle Weight
Rating (GAWR). This can cause
systems to break and change the
way the vehicle handles. This could
cause loss of control and a crash.

rail-mounted equipment should not
exceed 454 kg (1,000 lb).
When carrying removable items, a limit
on how many people carried inside the
vehicle may be necessary. Be sure to
weigh the vehicle before buying and
installing the new equipment.
Loading Points
When using this upper load platform,
be sure the load is securely tied down
to prevent it from shifting. The load's
center of gravity should be positioned
in a zone over the rear axle. The zone is
located in the area between the front
of each wheel well and the rear of each
wheel well. The center of gravity height
must not extend above the top of the
pickup box flareboard.

Driving and Operating
Caution (Continued)
The vehicle has a shift stabilization feature
that adjusts the transmission shifting to the
current driving conditions in order to reduce
rapid upshifts and downshifts. This shift
stabilization feature is designed to
determine, before making an upshift, if the
engine is able to maintain vehicle speed by
analyzing things such as vehicle speed,
throttle position, and vehicle load. If the
shift stabilization feature determines that a
current vehicle speed cannot be maintained,
the transmission does not upshift and
instead holds the current gear. In some
cases, this could appear to be a delayed
shift, however the transmission is operating
normally.

When the shift lever is moved from
D (Drive) to L (Manual Mode), a number
displays next to the L, indicating the current
transmission range.
In vehicles with gasoline engines, when the
shift lever is moved from D (Drive) to
L (Manual Mode), a downshift may occur.
The gear that the transmission is operating
in when the shift lever is moved from D
(Drive) to L (Manual Mode) determines if a
downshift occurs. See the following charts.
Manual Mode (Mechanical
Shifter)
Range Selection Mode
This number is the highest gear that the
transmission will allow while operating in
L (Manual Mode). All gears below that
number are available. As driving conditions
change, the transmission can automatically
shift to lower gears. For example, when L5 is
selected, 1 (First) through 5 (Fifth) gears are
automatically shifted by the transmission,
but 6 (Sixth) cannot be used until the plus/
minus button on the shift lever is used to
change to the range.
Range Selection Mode helps control the
vehicle transmission and vehicle speed while
driving downhill or towing a trailer.
It permits the manual selection of a desired
gear range.
To use this feature:
1. Move the shift lever to L (Manual Mode).

EPB Apply
To apply the EPB:
The vehicle may automatically apply the EPB
in some situations when the vehicle is not
moving. This is normal, and is done to
periodically check the correct operation of
the EPB system, or at the request of other
safety functions that utilize the EPB.
1. Be sure the vehicle is at a complete stop.
2. Press the EPB switch momentarily.
The red parking brake status light will flash
and then stay on once the EPB is fully
applied. If the red parking brake status light
flashes continuously, then the EPB is only
partially applied or there is a problem with
the EPB. A DIC message will display. Release
the EPB and try to apply it again. If the
light does not come on, or keeps flashing,
have the vehicle serviced. Do not drive the
vehicle if the red parking brake status light
is flashing. See your dealer.
If the EPB fails to apply, block the rear
wheels to prevent vehicle movement.

System Operation
Automatic EPB Release
The vehicle has a Traction Control System
(TCS) and StabiliTrak/Electronic Stability
Control (ESC), an electronic stability control
system. These systems help limit wheel spin
and assist the driver in maintaining control,
especially on slippery road conditions.
The EPB will automatically release if the
vehicle is running, placed into gear, and an
attempt is made to drive away. Avoid rapid
acceleration when the EPB is applied, to
preserve parking brake lining life.
When the vehicle is stopped on a grade, Hill
Start Assist (HSA) prevents the vehicle from
rolling in an unintended direction during the
transition from brake pedal release to
accelerator pedal apply. The brakes release
when the accelerator pedal is applied. If the
accelerator pedal is not applied within a few
minutes, the Electric Parking Brake will
apply. The brakes may also release under
other conditions. Do not rely on HSA to hold
the vehicle.
TCS activates if it senses that any of the
drive wheels are spinning or beginning to
lose traction. When this happens, TCS
applies the brakes to the spinning wheels
and reduces engine power to limit
wheel spin.
Brake Assist
Brake Assist detects rapid brake pedal
applications due to emergency braking
situations and provides additional braking to
activate the Antilock Brake System (ABS) if
the brake pedal is not pushed hard enough
to activate ABS normally. Minor noise, brake
pedal pulsation, and/or pedal movement
during this time may occur. Continue to

The vehicle can tow in D (Drive). Shift the
transmission to a lower gear if the
transmission shifts too often under heavy
loads and/or hilly conditions.
When parking your vehicle and your trailer
on a hill:
Backing Up
Hold the bottom of the steering wheel with
one hand. To move the trailer to the left,
move that hand to the left. To move the
trailer to the right, move that hand to the
right. Always back up slowly and, if possible,
have someone guide you.
1. Press and hold the brake pedal, but do
not shift into P (Park). Turn the wheels
toward the curb if facing downhill or
into traffic if facing uphill.
When towing at higher altitudes, engine
coolant will boil at a lower temperature
than at lower altitudes. If the engine is
turned off immediately after towing at high
altitude on steep uphill grades, the vehicle
could show signs similar to engine
overheating. To avoid this, let the engine
run, preferably on level ground, with the
transmission in P (Park) for a few minutes
before turning the engine off. If the
overheat warning comes on, see Engine
Overheating 0 347.
2. Have someone place chocks under the
trailer wheels.

3. Gradually release the brake pedal to
allow the chocks to absorb the load of
the trailer.
Caution
Turn more slowly and make wider arcs
when towing a trailer to prevent damage
to your vehicle. Making very sharp turns
could cause the trailer to contact the
vehicle.
4. Reapply the brake pedal. Then apply the
parking brake and shift into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
Viewing Systems
Make wider turns than normal when towing,
so the trailer will not go over soft shoulders,
over curbs, or strike road signs, trees,
or other objects. Always signal turns well in
advance. Do not steer or brake suddenly.
If equipped, the viewing systems on the
vehicle can improve visibility while hitching,
backing, and driving with a trailer. See

Four-Wheel Drive.
7. Slowly pull the trailer from the water.
.
If the boat launch surface is slippery,
have the driver remain in the vehicle
with the brake pedal applied while the
boat is being launched. The boat
launch can be especially slippery at
low tide when part of the ramp was
previously submerged at high tide. Do
not back onto the ramp to launch the
boat if you are not sure the vehicle
can maintain traction.
8. Once the vehicle and trailer have been
driven from the sloped part of the boat
ramp, the vehicle can be shifted from
four-wheel-drive high. Shift into the drive
mode that is appropriate for the road
conditions.
2. Slowly back down the boat ramp until
the boat is floating, but no further than
necessary.
3. Press and hold the brake pedal, but do
not shift into P (Park) yet.
4. Have someone place chocks under the
front wheels of the vehicle.

vehicle begins to slide toward the water,
remove your foot from the accelerator
pedal and apply the brake pedal. Seek
help to have the vehicle towed up
the ramp.
5. Gradually release the brake pedal to
allow the chocks to absorb the load of
the trailer.

Trailering is different than just driving the
vehicle by itself. Trailering affects the
handling, acceleration, braking, and
durability of your vehicle. Successful, safe
trailering takes correct equipment, and it
has to be used properly.
Maintenance when Trailer Towing
The vehicle needs service more often when
used to tow trailers. See Maintenance
Schedule 0 417. It is especially important to
check the engine oil, axle lubricant, belts,
cooling system, and brake system before
and during each trip.
When towing a trailer, the combined weight
of the vehicle, vehicle contents, trailer, and
trailer contents must be below all of the
maximum weight ratings for the vehicle,
including:

towing a trailer with the vehicle.
304
Driving and Operating
A trailering information label on the B-pillar
shows tow rating information for the
vehicle.
To check that the weight of the vehicle and
trailer are within the GCWR for the vehicle,
follow these steps:
1. Start with the "curb weight" from the
Trailering Information Label.
Warning
{
You and others could be seriously injured
or killed if the trailer is too heavy or the
trailer brakes are inadequate for the load.
The vehicle may be damaged, and the
repairs would not be covered by the
vehicle warranty.
2. Add the weight of the trailer loaded with
cargo and ready for the trip.
3. Add the weight of all passengers.
4. Add the weight of all cargo in the
vehicle.
5. Add the weight of hitch hardware such
as a draw bar, ball, load equalizer bars,
or sway bars.
Only tow a trailer if all the steps in this
section have been followed. Ask your
dealer for advice and information about
towing a trailer.
Gross Combined Weight (GCW) Alert
If equipped, the GCW Alert can display a
message in the Driver Information Center
(DIC), indicating that the estimated
combined weight of the vehicle and trailer
may exceed the vehicle’s GCWR, under
certain circumstances. See “Gross Combined
Weight Rating” above. The vehicle does not
actually measure the loaded weight of your
vehicle or trailer. It uses vehicle data to
estimate these weights after you begin
a trip.
6. Add the weight of any accessories or
aftermarket equipment added to the
vehicle.
Gross Combined Weight Rating (GCWR)
The resulting weight cannot exceed the
GCWR value on the Trailering Information
Label.
GCWR is the total allowable weight of the
completely loaded vehicle and trailer
including any fuel, passengers, cargo,
equipment, and accessories. Do not exceed
the GCWR for your vehicle. The GCWR for
the vehicle is on the Trailering Information
Label.
The GCWR can also be confirmed by
weighing the truck and trailer on a public
scale. The truck and trailer should be loaded
for the trip with passengers and cargo.
Driving and Operating
Maximum Trailer Weight
The maximum trailer weight rating is
calculated assuming the tow vehicle has a
driver, a front seat passenger, and all
required trailering equipment. This value
represents the heaviest trailer the vehicle
can tow, but it may be necessary to reduce
the trailer weight to stay within the GCWR,
GVWR, maximum trailer tongue load,
or GAWR-RR for the vehicle.
305
The alert will not activate unless:
GCWR is only one of the maximum weight
ratings applicable to your vehicle and trailer.
The GCW Alert does not estimate whether
the vehicle alone exceeds the GVWR, the
rear-axle weight exceeds GAWR-RR, the
trailer exceeds the Maximum Trailer Weight
Rating or the trailer tongue weight exceeds
the Maximum Tongue Weight Rating.
Always verify that the weight of the vehicle,

Weights listed apply for conventional trailers
and gooseneck/fifth-wheel trailers unless
otherwise noted.
Gross Vehicle Weight Rating (GVWR)
For information about the vehicle's
maximum load capacity, see Vehicle Load
Limits 0 204. When calculating the GVWR
with a trailer attached, the trailer tongue
weight must be included as part of the
weight the vehicle is carrying.
Warning
{
Always determine the actual weights of
the loaded vehicle and trailer using a
vehicle scale before beginning a trip.
Never use the GCW Alert to determine
whether the vehicle and trailer are
properly loaded or overloaded. Do not
drive with an overloaded vehicle or
trailer. Death, serious injury, or property
damage could occur.
A step bumper trailer hitch can only support
a total trailer weight up to 2 271 kg
(5,000 lb). If a trailer hitch ball is added to
the step bumper, check the hitch ball rating
to be sure it is higher than the total trailer
weight.
306
Driving and Operating
The trailer tongue weight contributes to the
Gross Vehicle Weight (GVW). GVW includes
the curb weight of your vehicle, any
passengers, cargo, equipment and the trailer
tongue weight. Vehicle options, passengers,
cargo, and equipment reduce the maximum
allowable tongue weight the vehicle can
carry, which also reduces the maximum
allowable trailer weight.
The trailer tongue weight (1) should be 10–
15% and fifth-wheel or gooseneck tongue
weight should be 15–25% of the total loaded
trailer weight (2). Some specific trailer types,
such as boat trailers, fall outside of this
range. Always refer to the trailer owner’s
manual for the recommended trailer tongue
weight for each trailer. Never exceed the
maximum loads for the vehicle, hitch, and
trailer.
Maximum Trailer Tongue Weight Rating
The Maximum Trailer Tongue Weight Rating
is the allowable trailer tongue weight that
the vehicle can support using a conventional
trailer hitch. It may be necessary to reduce
the overall trailer weight to stay within the
maximum trailer tongue weight rating while
still maintaining the correct trailer load
balance. A fifth-wheel or gooseneck hitch
may support a higher tongue weight.
Trailer Load Balance
The trailer load balance percentage is
calculated as: weight (1) divided by
weight (2) times 100.
The correct trailer load balance must be
maintained to ensure trailer stability.
Incorrect load balance is a leading cause of
trailer sway.
After loading the trailer, separately weigh
the trailer and then the trailer tongue and
calculate the trailer load balance percentage
to see if the weights and distribution are
appropriate for your vehicle. If the trailer
weight is too high, it may be possible to
transfer some of the cargo into your vehicle.
If the trailer tongue weight is too high or
too low, it may be possible to rearrange
some of the cargo inside of the trailer.
The Maximum Trailer Tongue Weight Rating
for a conventional trailer hitch or a fifth
wheel/gooseneck hitch is shown on the
Trailering Information Label.

Do not exceed the maximum allowable
tongue weight for your vehicle. Use the
shortest hitch extension available to position
the hitch ball closer to your vehicle. This will
help reduce the effect of the trailer tongue
weight on the trailer hitch and the rear axle.

{
In order to avoid serious injury or
If a cargo carrier is used in the trailer hitch
receiver, choose a carrier that positions the
load as close to the vehicle as possible.

property damage, always follow the hitch
manufacturer's instructions when securing
your draw bar/coupling device to the
vehicle's hitch receiver.
Ensure that the draw bar/coupling device
is secured with a locking retainer pin or
other means such that rotation of the pin
or locking mechanism will not cause the
pin to back out or loosen during use.
Failure to correctly secure the draw bar/
coupling device to the receiver can result
in separation of the hitch/receiver while
towing.
The GAWR-RR for the vehicle is on the
Trailering Information Label.
Rear Gross Axle Weight Rating
(GAWR-RR)
Ask your dealer for trailering information or
assistance.
The GAWR-RR is the total weight that can be
supported by the rear axle of the vehicle. Do
not exceed the GAWR-RR for the vehicle,
with the tow vehicle and trailer fully loaded
for the trip including the weight of the
trailer tongue. If using a weight-distributing
hitch, do not exceed the GAWR-RR before
applying the weight distribution spring bars.
308
Driving and Operating
Conventional Hitch
Always use the correct hitch equipment for
your vehicle. Crosswinds, large trucks going
by, and rough roads can affect the trailer
and the hitch.
Avoid sharp turns when using a step-bumper
hitch to prevent damage. Make wider turns
to prevent contact between your trailer and
your bumper.
A conventional hitch is bolted to the frame
or cross member of the tow vehicle, and is
generally rated Class 2, 3, or 4.
Proper hitch equipment for your vehicle
helps maintain control of the vehicle-trailer
combination. Many trailers can be towed
using a weight-carrying hitch which has a
coupler latched to the hitch ball, or a tow
eye latched to a pintle hook. Other trailers
may require a weight-distributing hitch that
uses spring bars to distribute the trailer
tongue weight between your vehicle and
trailer axles. Fifth-wheel and gooseneck
hitches may also be used. See “Maximum
Trailer Tongue Weight” under Trailer Towing
0 303 for weight limits with various hitch
types.
Consider using mechanical sway controls
with any trailer. Ask a trailering professional
about sway controls or refer to the trailer
manufacturer's recommendations and
instructions.
Gooseneck Hitch
A gooseneck hitch is designed to be coupled
to a special hitch leveraging a hitch ball, and
is mounted over the rear axle in the
truck bed.
Weight-Distributing Hitch and
Adjustment
Fifth-Wheel Hitch
A fifth-wheel hitch is mounted over the rear
axle in the truck bed, and leverages a

The hitch should be in the pickup bed so
that its centerline is over or near the rear
axle. Take care that it is not so far forward
that it will contact the back of the cab in
sharp turns. This is especially important for
short box pickups. Trailer pin box extensions
and sliding fifth-wheel hitch assemblies may
be used. There should be at least 15 cm
(6 in) of clearance between the top of the
pickup box and the bottom of the trailer
shelf that extends over the box.

Fifth-Wheel and Gooseneck Trailering
Fifth-Wheel and Gooseneck Trailering
Fifth-wheel and gooseneck trailers can be
used with many pickup models. These
trailers place a larger percentage of the
weight (kingpin weight) on the tow vehicle
than conventional trailers. Make sure this
weight does not cause the vehicle to exceed
GAWR or GVWR. Fifth-wheel or gooseneck
kingpin weight should be 15–25% of the
trailer weight up to the maximum amount
Cross the safety chains under the tongue of
the trailer to help prevent the tongue from
contacting the road if it becomes separated
from the hitch. Always leave enough slack in
the safety chains to allow the combination
to turn. Never allow safety chains to drag
on the ground.
Make sure the hitch is attached to the tow
vehicle frame rails. Do not use the pickup
box for support.

Trailer Sway Control (TSC)
If TSC is enabled, the Traction Control
Vehicles with StabiliTrak/Electronic Stability
Control (ESC) have a Trailer Sway Control
(TSC) feature. Trailer sway is unintended
side-to-side motion of a trailer while towing.
If the vehicle is towing a trailer and the TSC
detects that sway is increasing, the vehicle
brakes are selectively applied at each wheel,
to help reduce excessive trailer sway.
If equipped with the Integrated Trailer Brake
Control (ITBC) system, and the trailer has an
electric brake system, StabiliTrak/ESC may
also apply the trailer brakes.
System (TCS)/StabiliTrak/ESC warning light
will flash on the instrument cluster. Reduce
vehicle speed by gradually removing your
foot from the accelerator. If trailer sway
continues, StabiliTrak/ESC can reduce engine
torque to help slow the vehicle. TSC will not

Trailer Tires
Special Trailer (ST) tires differ from vehicle
tires. Trailer tires are designed with stiff
sidewalls to help prevent sway and to
support heavy loads. These features can
make it difficult to determine if the trailer
tire pressures are low only based on a visual
inspection.

on your vehicle.
Aftermarket Electronic Trailer Sway
Control Devices
Some trailers may come equipped with an
electronic device designed to reduce or
control trailer sway. Aftermarket equipment
manufacturers also offer similar devices that
connect to the wiring between the trailer

with the vehicle’s trailer brake or other
systems, including integrated anti-sway
systems, if equipped. Messages related to

more noticeable as vehicle speed
increases. At speeds above 72 km/h
(45 mph), this may cause the engine
coolant to overheat. Move or angle the
snow plow blade to allow increased
airflow to the radiator.
To increase the airflow, move the snow
plow blade position.
If driving more than 24 km/h (15 mph),
angle the plow blade position.
Make sure the weight on the front and
rear axles does not exceed the axle rating
for each.
Follow the snowplow manufacturer’s
recommendations for any rear ballast that
may be required. Rear ballast may be
required to ensure a proper front and rear
weight distribution ratio even though the
actual weight at the front axle may be
less than the front axle rating.
The snowplow manufacturer or installer
can assist in determining the amount of
rear ballast required to ensure that the
vehicle with the attached snowplow does
not exceed the GVW rating, the front and
rear axle ratings, or the front and rear
weight distribution ratio (refer to the GM
Upfitter Manual).
Caution (Continued)
repairs would not be covered by the
vehicle warranty. Unless the vehicle was
built to carry a snow plow, do not add
one to the vehicle. If the vehicle has RPO
VYU, then the payload the vehicle can
carry will be reduced when a snow plow
is installed. The vehicle can be damaged
if either the front or rear axle ratings or
the Gross Vehicle Weight Rating (GVWR)
are exceeded.

Adding a Snow Plow or Similar
Equipment
The plow the vehicle can carry depends on
many things, such as:
The options the vehicle came with, and
the weight of those options.
The weight and number of passengers to
be carried.
The weight of items added to the vehicle,
like a tool box or truck cap.

Driving and Operating
Front axle reserve capacity is the difference
between the Front Gross Axle Weight
Rating (GAWR) and the front axle weight of
the vehicle with full fuel, passengers, and
any other cargo. This is the amount of
weight that can be added to the front axle
before reaching the Front GAWR.
Where:
IW = Weight of added accessory
on the front. However, the front GAWR, rear
GAWR, and Gross Vehicle Weight
Rating (GVWR) must never be exceeded.
IA = Distance that the accessory is in
front of the front axle
Warning
{
IW.B. = Vehicle Wheelbase
On some vehicles that have certain front
mounted equipment, such as a snow
plow, it may be possible to load the front
axle to the front Gross Axle Weight
Rating (GAWR) but not have enough
weight on the rear axle to have proper
braking performance. If the brakes cannot
work properly, the vehice could crash.
Always follow the snow plow
For example, adding a 318 kg (700 lb) snow
plow actually adds more than 318 kg (700 lb)
to the front axle. Using the formula, if the
snow plow is 122 cm (4 ft) in front of the
front axle and the wheelbase is 305 cm
(10 ft), then:
To calculate the amount of weight any front
accessory, such as a snow plow, is adding to
the front axle, use this formula:
IW = 318 kg (700 lb)
IA = 122 cm (4 ft)
manufacturer or installer's
IW.B. = 305 cm (10 ft)
recommendation for rear ballast to
ensure a proper front and rear weight
distribution ratio. Maintaining a proper
front and rear weight distribution ratio is
necessary to provide proper braking
performance.
(W x (A + W.B.)/W.B. = (318 x (122 + 305))/305
= 445 kg (980 lb)
This means if the front axle reserve capacity
is more than 445 kg (980 lb), the snow plow
could be added without exceeding the
front GAWR.
See your dealer for additional advice and
information about using a snow plow on the
vehicle. Also, see Vehicle Load Limits 0 204.
(W x (A + W.B.)) /W.B.= Weight the accessory
is adding to the front axle.
Heavier equipment can be added on the
front of the vehicle if less cargo or fewer
passengers are carried, or by positioning
cargo toward the rear. This reduces the load

Pickup Conversion to Chassis Cab
We are aware that some vehicle owners
might consider having the pickup box
removed and a commercial or recreational
body installed. Owners should be aware
that, as manufactured, there are differences
between a chassis cab and a pickup with the
box removed which could affect vehicle
safety. The components necessary to adapt
a pickup to permit its safe use with a
specialized body should be installed by the
body builder.
