Protective effect  
Vehicle equipment  
Airbags are not activated by every collision, for  
example in minor accidents and rear-end colli‐  
sions.  
This chapter describes all the standard equip‐  
ment, national-market-specific equipment and  
optional extras offered in the model series.  
Consequently, you will find that it contains de‐  
scriptions of items not available in a particular  
vehicle on account of a combination of options,  
for example, or the constraints applying to cer‐  
tain national-market versions. This also applies  
to safety-relevant functions and systems.  
Even if all these instructions are complied with,  
depending on the circumstances in which an  
accident occurs, certain injuries as a result of  
contact with the airbag cannot be entirely ruled  
out.  
The noise caused by the deployment of an air‐  
bag may lead to brief and generally temporary  
hearing loss in vehicle occupants sensitive to  
noise.  
Country-specific regulations must be observed  
when using the corresponding functions and  
systems.  
Information for optimal protective effect  
of the airbags  
Airbags  
There are the following airbags beneath the  
covers indicated:  
Keep your distance from the airbags.  
Always grip the steering wheel on the rim,  
with your hands in the 3 o’clock and  
9 o’clock positions, to minimise the risk of  
injury to the hands or arms in the event of  
the airbag being triggered.  
No other persons, pets or objects should  
be held or permitted to remain between  
the airbag and yourself.  
Do not use the front airbag cover on the  
front passenger’s side as a tray.  
Keep the dashboard and windscreen in the  
area of the passenger’s side free, i.e. do  
not attach adhesive foil or covers and do  
not fit brackets, for example for navigation  
devices or mobile phones.

Front airbags  
Side airbags in the seat backrests  
Front airbags  
Make sure that the front passenger adopts  
a correct seated position, i.e. leaves his or  
her feet in the footwell and does not rest  
feet or legs on the instrument panel, other‐  
wise he/she could sustain leg injuries in the  
event of the front airbag being triggered.  
Front airbags protect the driver and passenger  
in the event of a head-on collision where the  
action of the seat belts alone would be insuffi‐  
cient.  
Side airbags  
In a side-on crash, the side airbag protects the  
upper body at the side.  
Do not fit seat covers, cushions or other  
objects not specifically approved for seats  
with integral side airbags to the front seats.

Controls  
Safety  
Do not hang items of clothing such as  
coats or jackets over the backrests.  
When the ignition, see page 48, is switched on,  
the warning light shows briefly to indicate that  
the entire airbag system and the belt tension‐  
ers are operational.  
Make sure that passengers do not lean  
their heads against the side or head air‐  
bags; otherwise they could be injured,  
should the airbags deploy.  
Airbag system faulty  
Warning light does not show when the ig‐  
nition is switched on.  
Do not dismantle the airbag system.  
Do not dismantle the steering wheel.  
Warning light remains lit.  
Never attach any material to the airbag  
covers with adhesive; never place material  
over them or modify them in any way.  
Airbag system faulty; have it checked  
without delay  
In the event of a fault in the airbag system,  
have it checked without delay, as there is oth‐  
erwise the risk that the system will not function  
as intended even if a sufficiently severe acci‐  
dent occurs.◀  
Do not modify individual components of  
the system or its wiring in any way. The  
same applies for the covers of the steering  
wheel, the dashboard and the seats.◀  
In the event of faults, taking the airbags  
out of use and after they have been trig‐  
Not for Australia/New Zealand: key

gered  
Avoid touching the system’s components im‐  
mediately after it has been triggered, as there  
is a risk of sustaining burns.  
Only commission your Service Centre or au‐  
thorised workshops with checking, repairing or  
dismantling and scrapping airbag generators,  
as your Service Centre or authorised work‐  
shops have the required legal permits for han‐  
dling explosives.  
Any careless or unskilled interference with the  
system could lead to its failure or to accidental  
triggering with the risk of injury.◀  
You can deactivate and subsequently reacti‐  
vate the front and side airbags for the front  
passenger by means of a key switch. This key  
switch is set in the side of the dashboard on  
the passenger side.  
Operational readiness of the airbag  
system  
You can deactivate and reactivate the airbags  
for the front passenger only when the car is at  
a standstill and the front passenger's door is  
open.

cates whether the airbags are activated or de‐  
activated.  
Front passenger airbags are deactivated.  
The driver's airbags remain active.  
If a child restraint system is no longer fitted in  
the front passenger's seat, reactivate the front  
passenger airbags so that they are triggered as  
intended in the event of an accident.  
When front passenger airbags are deacti‐  
vated, the indicator light remains illumina‐  
ted.  
When front passenger airbags are activa‐  
ted, the indicator light is not illuminated.  
Activating the front passenger airbags

Pedestrian protection  
system, active  
While the key is pressed in‐  
wards, turn it to the ON position  
as far as it will go.  
Principle  
Once the stop position has been reached, re‐  
move the key.  
With the active pedestrian protection system,  
the engine compartment lid is raised in the  
event of a pedestrian colliding with the vehicle  
front. Sensors under the bumper detect pe‐  
destrians. This provides additional deformation  
space under the active engine compartment lid  
for the subsequent head impact.  
Key switch in end position  
Make sure that the key switch is in the  
corresponding end position. Otherwise the air‐  
bags are not activated/deactivated.◀  
Do not touch individual components  
The front passenger airbags are reactivated  
and can deploy correctly if the need arises.  
Do not touch the actuators of the hinge  
and engine compartment locks, as otherwise  
there is a risk of injury due to inadvertent acti‐  
vation of the system.◀

For safety reasons, the system can also trigger  
in rare cases if a pedestrian impact cannot be  
fully excluded, for example:  
Only commission your Service Centre with the  
inspection, repair or disassembly/scrapping of

Triggered pedestrian protection  
system  
Principle  
The system detects a pressure loss in a tyre  
on the basis of a comparison between the  
speeds at which the individual wheels rotate  
while the vehicle is in motion.  
After triggering or damage  
After triggering of the active engine com‐  
partment lid or in the event of damage, have  
the system checked and replaced.  
If a tyre loses pressure, its rolling circumfer‐  
ence changes, and this in turn alters the speed  
of rotation of the corresponding wheel. This  
change is detected and interpreted as a punc‐  
ture.  
Only have this work carried out at the Service  
Centre, as otherwise correct functioning of this  
safety device is not ensured.◀  
Malfunction  
Operating requirements  
The indicator light lights up.  
The system must have been initialised with  
correct tyre pressure, otherwise reliable signal‐  
ling of a puncture cannot be assured. Each  
time the tyre pressure is adjusted or a tyre or  
wheel is changed, initialise the system again.  
The system has triggered or mal‐  
functioned.  
You can continue your journey, but moderate  
your speed and exercise due caution. Drive im‐  
mediately to the nearest Service centre to have  
the system checked and repaired.  
System limits  
Sudden tyre damage  
Do not open the engine compartment lid  
No warning can be given of extreme,  
sudden tyre failure caused by external fac‐  
tors.◀  
After the warning lamp has appeared, do  
not open the engine compartment lid, as oth‐  
erwise damage can be caused.◀  
A natural, even loss of pressure in all four tyres  
that occurs over time is not detected.  
Notes  
In the following situations, the system could be  
slow to respond or operate incorrectly:

Initialising  
On initialisation, the current tyre pressures are  
stored as a reference for detection of a punc‐  
ture. The initialisation is started by confirming  
the correct pressures.  
5. Drive off.  
When driving with snow chains fitted, do not  
initialise the system.  
Initialisation is completed while the car is  
moving.  
Operating principle, see page 67.  
Indication of a puncture  
1. Start engine shortly before the trip, do not  
drive off yet.  
The warning lights light up yellow and  
red. An acoustic signal also sounds.  
2. Repeatedly tap button 1 on the turn indica‐  
tor lever up or down until the correspond‐  
ing symbol appears, accompanied by "RE‐  
SET".  
There is a puncture or substantial  
loss of tyre pressure.  
1. Reduce your speed and cautiously stop  
the car. Avoid violent or sudden braking  
and steering manoeuvres.  
2. Check whether the vehicle is equipped  
with standard tyres or runflat tyres.  
The symbol identifying run-flat tyres, see  
page 158, is the circle with the letters RSC  
on the tyre sidewall.  
Do not continue a journey without run-  
flat tyres  
3. Press button 2 to confirm the selection of  
the runflat indicator.  
Do not continue your journey if the vehicle is  
not equipped with run-flat tyres, otherwise a  
serious accident could occur.◀  
It is possible that Dynamic Stability Control  
DSC is activated as soon as the message for a  
puncture appears.  
What to do in the event of a puncture  
Standard tyres  
1. Identify the damaged tyre.  
83  
 
Controls  
Safety  
Do this by checking the air pressure in all  
four tyres.  
As the possible distance largely depends on  
the strain on the vehicle during the journey,  
this can be shorter, or longer if the vehicle is  
driven carefully, according to speed, road con‐  
dition, outside temperature, load etc.  
If all four tyres are inflated to the correct  
pressures, the runflat indicator might not  
have been initialised. In this case initialise  
the system.  
Continuing a journey with a flat tyre  
If it is not possible to identify, contact a  
Service centre.  
Drive with care and do not exceed a  
speed of 80 km/h, 50 mph.  
2. Fix the puncture.  
If tyre pressure has fallen, vehicle handling  
changes, for example reduced directional sta‐  
bility when braking, longer stopping distance  
and modified self-steering behaviour.◀  
Run-flat tyres  
If a tyre has punctured you can continue your  
journey, driving at speeds up to a maximum of  
80 km/h, 50 mph.  
Final tyre failure  
Vibration or loud noises while driving  
may be an indication that the tyre has finally  
failed. Reduce your speed and stop, otherwise  
sections of the tyre could become detached  
and cause an accident. Do not drive the car  
any further; contact your Service Centre in‐  
stead.◀  
Continuing a journey with a puncture  
If you continue a journey with a puncture:  
1. Avoid violent or sudden braking and steer‐  
ing manoeuvres.  
2. Do not exceed a speed of 80 km/h, 50 mph  
any longer.  
3. As soon as you get an opportunity, check  
the tyre pressure in all four tyres.  
Tyre Pressure Monitor TPM  
If all four tyres are inflated to the correct  
pressures, the runflat indicator might not  
have been initialised. In this case initialise  
the system.  
Principle  
The system monitors the tyre pressure in the  
four fitted tyres. The system issues a warning  
if the tyre pressure has dropped significantly in  
one or more of the tyres. Sensors in the tyre  
valves measure the tyre pressure.  
Maximum possible distance with tyres entirely  
deflated:  
The possible distance with a puncture de‐  
pends on the load and strain on the vehicle  
during the journey.  
Notes  
Tyre damage caused by external factors  
When the vehicle is subject to medium load,  
the possible distance is approx. 80 km,  
50 miles.  
No warning can be given of sudden tyre  
damage caused by external factors.◀  
When driving with damaged tyres, the vehicle  
handling changes, for example quicker loss of  
traction when braking, longer stopping dis‐  
tance and modified self-steering behaviour.  
Adapt driving style accordingly. Avoid abrupt  
steering or driving over obstacles, for example  
curbs, potholes etc.  
To operate the system, also note the informa‐  
tion in the section entitled Tyre pressure, see  
page 157.  
Operating requirements  
The system must have been reset with the  
correct tyre pressure, since otherwise reliable

4. Press button 2 for approximately 5 sec‐  
onds until the small warning light shines  
yellow and the following display appears:  
Perform a system reset after adjusting the tyre  
pressure to a new value or after changing the  
tyres or wheels.  
Always use tyres with the electronic TPM sys‐  
tem to ensure error-free system operation.  
Resetting the system  
Perform a system reset after adjusting the tyre  
pressure to a new value or after changing the  
tyres or wheels.  
5. Drive off.  
Operating principle, see page 67.  
After you have driven for a short time at  
over 30 km/h, the set tyre pressures are  
adopted as the setpoint values. The sys‐  
tem reset is completed during the drive,  
which can be interrupted at any time. The  
reset is automatically resumed when the  
drive is continued. The indicator light goes  
out on successful completion of the reset.  
1. Start the engine, but do not drive off.  
2. Repeatedly tap button 1 on the turn indica‐  
tor lever up or down until the right symbol  
appears, accompanied by "RESET".  
Message in the event of low tyre  
pressure  
The warning lights light up yellow  
and red. An acoustic signal also  
sounds.  
3. Press button 2 to confirm the selection of  
the Tire Pressure Monitor.  
There is a puncture or substantial  
loss of tyre pressure.  
The following display appears:  
The system has not been reset. The sys‐  
tem therefore issues a warning in the event  
of a deviation from the most recently saved  
tyre pressures.  
1. Reduce your speed and cautiously stop  
the car. Avoid violent or sudden braking  
and steering manoeuvres.  
2. Check whether the vehicle is equipped  
with standard tyres or runflat tyres.

rect).  
If the pressure of all four tyres is correct,  
the Tire Pressure Monitor may not have  
been reset. Then reset the system.

Safety  
Controls  
The tyre pressure depends on the temperature  
of the tyre. When the temperature of the tyre  
increases, such as during driving or through  
exposure to the sun, the tyre pressure increa‐  
ses. The tyre pressure decreases when the  
temperature of the tyre falls. As a result, when  
the temperature drops significantly, a warning  
may be issued on the basis of the set warning  
limits.
