Front airbags  
Side airbag  
Front airbags protect the driver and front pas‐  
senger in the event of a head-on collision where  
the protection of the seat belts alone would no  
longer be sufficient.  
In a side-on crash, the side airbag protects the  
side of the body in the chest and pelvic area.  
Head airbag  
The head airbag protects the head in the event  
of a side-on crash.  
151  
Safety  
CONTROLS  
Do not hang items of clothing for example  
coats or jackets over the backrests.  
Protective effect  
Airbags are not activated in every collision, for ex‐  
ample in minor accidents and rear-end collisions.  
Do not modify individual components of the  
system or its wiring. This also applies to the  
covers of the steering wheel, the dashboard  
and seats.  
Information for optimum airbag  
effectiveness  
Do not dismantle the airbag system.  
Even if all this information is observed, injuries re‐  
sulting from contact with the airbag cannot be  
entirely ruled out in some circumstances.  
WARNING  
If the seat position is incorrect or the deploy‐  
ment area of the airbag is restricted, the airbag  
system cannot provide the intended level of  
protection or may cause additional injuries  
when it deploys. There is a danger of injury or  
even death. Observe the following to achieve  
optimum protective effect.  
The noise caused by the deployment of an air‐  
bag may lead to temporary hearing loss for vehi‐  
cle occupants sensitive to noise.  
Operational readiness of the  
airbag system  
Keep your distance from the airbags.  
Safety notes  
Always grip the steering wheel at the steering  
wheel rim. Place your hands in the 3 o'clock  
and 9 o'clock positions to minimise the risk of  
injury to hands or arms when the airbag de‐  
ploys.  
WARNING  
Individual components of the airbag system  
may be hot after airbag deployment. There is a  
danger of injury. Do not touch individual com‐  
ponents.  
Make sure that vehicle occupants keep their  
head away from the side airbag.  
Make sure that the front-seat passenger is  
sitting correctly, i.e. with their feet and legs in  
the footwell, not resting on the dashboard.  
WARNING  
Do not place any other persons, pets or ob‐  
jects between the airbags and occupants.  
Work carried out incorrectly can lead to a fail‐  
ure, a malfunction or accidental deployment of  
the airbag system. If there is a malfunction, the  
airbag system might not deploy as intended in  
an accident, even if the impact is of the appro‐  
priate severity. There is a danger of injury or  
even death. Have the airbag system tested, re‐  
paired or removed and disposed of by a Service  
Partner of the manufacturer or another qualified  
Service Partner or a specialist workshop.  
Keep the dashboard and windscreen area on  
the passenger side clear, for example do not  
attach adhesive foil or covers and do not fit  
brackets for navigation devices or mobile tel‐  
ephones.  
Do not glue the airbag covers and do not  
cover or modify them in any way.  
Do not use the front airbag cover on the front  
passenger's side as a tray.  
Do not install seat covers, cushions or other  
objects on the front seats if they are not spe‐  
cifically designed for use on seats with inte‐  
gral side airbags.

Active pedestrian  
protection  
WARNING  
If the system has triggered or is damaged, its  
functions will be restricted, or it may no longer  
work at all. There is a danger of injury or even  
death.  
Principle  
The active pedestrian protection system raises  
the bonnet if the vehicle's front end collides with  
a pedestrian. Sensors underneath the bumper  
are used for detection. This provides additional  
deformation space underneath the bonnet for  
the subsequent head impact.  
If the system has triggered or is damaged, have  
it checked and renewed at a Service Partner of  
the manufacturer or another qualified Service  
Partner or a specialist workshop.  
Safety notes  
NOTE  
WARNING  
Opening the bonnet when the pedestrian pro‐  
tection system has triggered may damage the  
bonnet or the pedestrian protection system.  
There is a risk of material damage. Do not open  
the bonnet after the Check Control message is  
displayed. Have the system checked by a Serv‐  
ice Partner of the manufacturer or another  
qualified Service Partner or a specialist work‐  
shop.  
The system may trigger inadvertently if contact  
is made with individual components of the  
hinges and bonnet locks. There is a danger of  
injury or damage to property. Do not touch indi‐  
vidual components of the hinges and bonnet  
locks.  
WARNING  
Modifications to the pedestrian protection sys‐  
tem can lead to a failure, a malfunction or acci‐  
dental triggering of the pedestrian protection  
system. There is a danger of injury or even  
death. Do not modify the pedestrian protection  
system, its individual components or its wiring.  
Do not dismantle the system.  
System limits  
The active pedestrian protection system is only  
triggered at speeds between approx. 20 km/h,  
12 mph and 55 km/h, 34 mph.  
For safety reasons, the system may also trigger  
in rare instances where impact with a pedestrian

WARNING  
A damaged standard tyre with too little or no  
tyre inflation pressure impairs driving character‐  
istics, for example steering and braking. Tyres  
with run-flat properties allow a limited level of  
stability to be maintained. There is a risk of ac‐  
cident. Do not continue driving if the vehicle is  
fitted with normal tyres. Comply with the notes  
on run-flat tyres and continuing to drive with  
these tyres.

Possible driving distance with a deflated  
tyre  
Run-flat tyres  
Safety notes  
The possible driving distance varies depending  
on the load and stresses the vehicle is subjected  
to, for example speed, the nature of the road sur‐  
face, outside temperature. The driving distance  
may be shorter or, if a more careful driving style  
is adopted, may also be longer.  
WARNING  
A run-flat tyre which has low tyre inflation pres‐  
sure or no tyre inflation pressure at all will  
change the vehicle's handling characteristics,  
for example there may be reduced directional  
stability when braking, longer braking distances  
and different self-steering characteristics.  
There is a risk of accident. Drive with care and  
do not exceed a speed of 80 km/h, 50 mph.  
If the vehicle is moderately loaded and used un‐  
der favourable conditions, it is possible to travel  
up to 80 km, 50 miles.  
Driving properties with damaged tyres  
On a journey with damaged tyres, handling char‐  
acteristics change and may result in the following  
situations, for example:  
WARNING  
The vehicle losing traction more quickly.  
Longer braking distances.  
Continuing to drive with a flat tyre can result in  
heavy trailers starting to slalom. There is a dan‐  
ger of accidents or damage to property. When  
driving with a trailer and a flat tyre, do not ex‐  
ceed the speed of 60 km/h, 35 mph. If the  
trailer starts to snake, brake immediately and  
make the necessary steering corrections as  
carefully as possible.  
Different self-steering characteristics.  
Adapt your driving style. Avoid abrupt steering or  
driving over obstacles, for example kerbs or pot‐  
holes.  
Final tyre failure  
Vibration or loud noises during the journey may  
be an indication that the tyre has finally failed.  
Maximum speed  
Reduce your speed and stop the vehicle. Parts of  
the tyre could detach, which might lead to an ac‐  
cident.  
If a tyre is damaged you can continue your jour‐  
ney, but do not exceed a maximum speed of  
80 km/h, 50 mph.  
Do not continue driving, but instead contact a  
Service Partner of the manufacturer or another  
qualified Service Partner or a specialist work‐  
shop.  
Continuing a journey with a flat tyre  
If you continue a journey with a flat tyre:  
1. Avoid heavy braking and sudden steering  
manoeuvres.  
System limits  
Temperature  
The tyre inflation pressure depends on the tem‐  
perature of the tyre.  
2. Do not exceed a speed of 80 km/h, 50 mph.  
3. As soon as you get an opportunity, check the  
tyre pressure in all four tyres.  
If all four tyres are inflated to the correct tyre  
inflation pressures, the Tyre Pressure Monitor  
might not have been reset. Perform a reset.  
The tyre inflation pressure increases as the tyre  
temperature increases, for example during driv‐  
ing or due to exposure to sunlight.

be detected and reported as a flat tyre.  
Through this behaviour, a warning may be trig‐  
gered if there are major temperature drops, due  
to the given warning limits.  
The system does not measure the tyre inflation  
pressure as such.  
Operating requirements  
The following requirements must be met for the  
system, otherwise reliable signalling of a loss of  
tyre inflation pressure is not ensured:  
Sudden loss of tyre inflation  
pressure  
No warning can be given in the event of extreme,  
sudden tyre failure caused by external factors.  
After every tyre or wheel change, an initialisa‐  
tion must be carried out when the tyre infla‐  
tion pressures are correct.  
Reset not carried out  
The system will not function correctly if a reset  
has not been carried out, for example, a flat tyre  
is reported in spite of the correct tyre pressure.  
An initialisation must be carried out after the  
tyre inflation pressure has been adjusted to a  
new value.  
Malfunction  
Status display  
The yellow warning lamp flashes and is  
then illuminated continuously. A Check  
Control message is shown. Tyre pres‐

Initialising  
On initialisation, the current tyre pressures are  
saved as a reference for detection of a flat tyre.  
Initialisation is started by confirming the correct  
tyre inflation pressures.  
Principle  
The system identifies a loss of tyre inflation pres‐  
sure by comparing the rotational speeds of the  
individual wheels during the journey.  
When driving with snow chains fitted, do not initi‐  
alise the system.  
If a tyre loses inflation pressure, its diameter  
changes. This in turn alters the rotational speed

traffic conditions. Observe the traffic situation  
and intervene actively if the situation warrants it.  
Principle  
The system can help avoid accidents. If an acci‐  
dent cannot be avoided, the system helps to re‐  
duce the collision speed.  
The system warns of the possible risk of collision  
and brakes automatically, as necessary.  
The automatic braking intervention is done with  
limited force and duration.  
WARNING  
The system is controlled by a camera in the area  
of the rear-view mirror.  
Displays and warnings do not relieve you of  
your personal responsibility. System limitations  
can mean that warnings or system responses  
are not issued or are issued too late, incorrectly  
or without justification. There is a risk of acci‐  
dent. Adapt your driving style to the traffic con‐  
ditions. Observe the traffic situation and inter‐  
vene actively if the situation warrants it.  
The front-end collision warning is operational  
even if Cruise Control is disabled.  
When deliberately moving closer to a vehicle, the  
front-end collision warning and braking interven‐  
tion are activated later to avoid unjustified system  
responses.

Acute warning with braking function  
An acute warning is given when the vehicle is ap‐  
proaching another object at a high differential  
speed and there is an immediate risk of a colli‐  
sion.  
Detection range  
The detection ability of the system is limited.  
The driver must intervene personally if there is  
an acute warning. If necessary, the driver is assis‐  
ted by slight automatic brake intervention if there  
is a risk of collision.  
For this reason, the system may fail to respond  
or only respond after a delay.  
For example it is possible that the following may  
not be detected:  
An acute warning can be triggered even without  
a previous advance warning.  
Slow-moving vehicle when approaching it at  
high speed.  
Brake intervention  
Vehicles suddenly cutting in or braking heav‐  
ily.  
The warning prompts the driver to take action.  
Maximum braking force is used during a warning.  
Braking force support requires the brake pedal to  
be pressed sufficiently quickly and firmly. The  
system can also assist by applying the brakes  
lightly if there is the risk of a collision. At low  
speeds, the vehicle can be braked to a stop.  
Vehicles with an unusual rear appearance.  
Two-wheeled vehicles ahead.  
Functional limitations  
The system may have limited functionality in the  
following situations, for example:  
Manual gearbox: when the vehicle is braked to a  
stop, the engine may shut off.  
In thick fog, wet conditions or snow.  
On sharp bends.  
The brakes are only applied if driving stability has  
not been impaired, for example by deactivation of  
Dynamic Stability Control DSC.  
When Driving Stability Control Systems are  
limited or deactivated, for example DSC OFF.  
A brake intervention can be discontinued either  
by depressing the accelerator pedal or by ac‐  
tively moving the steering wheel.  
If, depending on equipment, the field of view  
of the camera in the mirror or the radar sen‐  
sor is soiled or covered.  
Object detection may be limited. Take into ac‐  
count the detection range limits and the func‐  
tional limitations.

Manual speed limiter  
Principle  
The system can be used to set a speed limit so  
that speed restrictions are not exceeded.  
Operation  
Switching on  
General  
Press the button on the steering wheel.  
The system enables speeds from a value of  
30 km/h/20 mph and above to be set as a speed  
limit. Below the set speed limit, the vehicle can  
be driven without restriction.  
The current speed is adopted as the speed limit.  
When switching on when at a standstill or driving  
at low speed, 30 km/h/20 mph is set as the  
speed limit.  
Exceeding the speed limit  
In particular situations the speed limit can be de‐  
liberately exceeded by accelerating strongly.  
The status display is shown and, depending on  
the instrument cluster, a marking in the speed‐  
ometer is set to the corresponding speed.  
The system gives a warning if the travelling  
speed exceeds the set speed limit.  
When activating the speed limit it is possible that  
Dynamic Stability Control DSC will be switched  
on and the drive mode switched to COMFORT.  
No brake intervention  
Switching off  
If the set speed limit has been reached or unin‐  
tentionally exceeded, for example when driving  
downhill, there is no active brake intervention.  
Press the button on the steering wheel.  
If you set a speed limit during the journey which  
is below the current speed, the vehicle rolls until  
the driving speed drops below the speed limit.  
The system switches off automatically in the  
following situations, for example:  
When engaging reverse gear.  
When switching the engine off.  
When switching on Cruise Control.  
When activating some programs using the  
Driving Experience Control.  
The displays turn off.

General  
Function  
The system is switched on every time the engine  
is started and cannot be switched off.  
After commencement of the journey, the system  
adapts to the driver so that any decrease in at‐  
tention or fatigue can be detected.  
This process considers the following criteria:  
Personal driving style, for example steering.  
Driving conditions, for example time of day,  
duration of journey.  
Normal braking: brake lights illuminate.  
Heavy braking: brake lights flash.  
The system is active from approxi‐  
mately 70 km/h, 43 mph and can display a rec‐  
ommendation to take a break.  
Shortly before the vehicle comes to a standstill,  
the hazard warning lights are activated.  
To deactivate the hazard warning lights:  
Accelerate.  
Break recommendations  
If the driver shows signs of decreasing attention  
or of fatigue, a message is shown on the Control  
Display with the recommendation to take a  
break.  
Press the hazard warning lights button.  
A recommendation to take a break will only be  
displayed once during an uninterrupted journey.  
Attentiveness assistant  
After a break, another break recommendation  
cannot be displayed until after approximately  
45 minutes at the earliest.  
Principle  
The system can detect decreasing attentiveness  
or the onset of fatigue in the driver on long mo‐  
notonous journeys, for example on motorways. In  
such situations, the system recommends you  
take a break.  
System limits  
The system may have limited functionality in sit‐  
uations such as the following and an incorrect  
warning, or no warning at all, may be given:  
Safety note  
If the time is set incorrectly.  
When the speed is predominantly below ap‐  
prox. 70 km/h, 43 mph.  
WARNING  
The system does not relieve you of your per‐  
sonal responsibility to assess your physical  
condition correctly. Increasing inattention or fa‐  
tigue might not be detected, or may not be de‐  
tected in good time. There is a risk of accident.  
Make sure that you, as the driver, are rested  
and alert. Adapt your driving style to the traffic  
conditions.  
If a sporty driving style is adopted, for exam‐  
ple sharp acceleration or fast cornering.  
In active driving situations, for example fre‐  
quent lane changes.  
In poor road conditions.  
In strong crosswinds.  
The system is reset approximately 45 minutes  
after the vehicle is stopped, for example when  
taking a break during a long motorway journey.
