The following suggestions will help to save
your fuel.
WARNING
.
Select the proper gear position for the
speed and road conditions.
The performance and long life of your
vehicle are dependent on how you handle
and care for your vehicle while it is new.
Follow these instructions during the first
1,000 miles (1,600 km):
.
Never inhale engine exhaust gas.
Engine exhaust gas contains
carbon monoxide, a colorless
and odorless gas which is dan-
gerous, or even lethal, if inhaled.
.
Avoid sudden acceleration or decelera-
tion. Always accelerate gently until you
reach the desired speed. Then try to
maintain that speed for as long as
possible.
.
Do not race the engine. And do not
allow engine speed to exceed 4,000
rpm except in an emergency.
.
.
.
Always properly maintain the en-
gine exhaust system to prevent
engine exhaust gas from entering
the vehicle.
.
Do not pump the accelerator and avoid
racing the engine.
.
.
.
Do not drive at one constant engine or
vehicle speed, either fast or slow.
Avoid starting suddenly and rapid ac-
celeration, except in an emergency.
Avoid hard braking, except in an emer-
gency.
.
.
.
Avoid unnecessary engine idling.
Keep the engine properly tuned.
Never run the engine in a closed
space, such as a garage, except
for the brief time needed to drive
the vehicle in or out of it.
Keep the tires inflated to the correct
pressure shown on the tire inflation
pressure label, which is located under
the door latch on the driver’s side. Low
pressure will increase tire wear and fuel
consumption.
Avoid remaining in a parked ve-
hicle for a lengthy time while the
engine is running. If that is un-
avoidable, then use the ventila-
tion fan to force fresh air into the
vehicle.
The same break-in procedures should be
applied to an overhauled engine, newly
mounted engine or when brake pads are
replaced with new ones.
.
.
.
Use the air conditioner only when
necessary.
Keep the front and rear wheels in
proper alignment.
Avoid carrying unnecessary luggage or
cargo.
.
Always keep the front ventilator
inlet grille free from snow, leaves
or other obstructions to ensure
that the ventilation system al-
ways works properly.

backfiring or incomplete combustion),
have your vehicle checked and re-
paired by an authorized SUBARU deal-
er.
Do not apply undercoating or rust
prevention treatment to the heat shield
of catalytic converter and the exhaust
system.
.
.
If at any time you suspect that
exhaust fumes are entering the
vehicle, have the problem
checked and corrected as soon
as possible. If you must drive
under these conditions, drive
only with all windows fully open.

.
.
Keep the rear gate closed while
driving to prevent exhaust gas
from entering the vehicle.
Do not drive with an extremely low fuel
level.
WARNING
NOTE
.
.
Avoid fire hazards. Do not drive
or park the vehicle anywhere
near flammable materials (e.g.,
grass, paper, rags or leaves),
because the catalytic converter
operates at very high tempera-
tures.
Due to the expansion and contraction
of the metals used in the manufacture
of the exhaust system, you may hear a
crackling sound coming from the ex-
haust system for a short time after the
engine has been shut off. This sound is
normal.
The catalytic converter is installed in the
exhaust system. It serves as a catalyst to
reduce HC, CO and NOx in exhaust gases,
thus providing cleaner exhaust.
To avoid damage to the catalytic converter:
Keep everyone and flammable
materials away from the exhaust
pipe while the engine is running.
The exhaust gas is very hot.
.
Use only unleaded fuel. Even a small
amount of leaded fuel will damage the
catalytic converter.
.
Never start the engine by pushing or
pulling the vehicle.
.
.
Avoid racing the engine.
Never turn the ignition switch to the
“OFF” position while the vehicle is
moving.
.
Keep your engine tuned-up. If you feel
the engine running rough (misfiring,
