SafetyVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Airbags
1Front airbag, driver2Front airbag, front passenger3Head airbag4Side airbag5Knee airbagsFront airbags
Front airbags help protect the driver and front
passenger by responding to frontal impacts in
which safety belts alone cannot provide ade‐
quate restraint.
Side airbags
In a lateral impact, the side airbag supports the
side of the body in the chest and lap area.Head airbags
In a lateral impact, the head airbag supports
the head.
Knee airbagThe knee airbag supports the legs in a frontal
impact.Seite 94ControlsSafety94

Protective action
Airbags are not triggered in every impact situa‐
tion, e.g., in less severe accidents or rear-end
collisions.
Information on how to ensure the optimal
protective effect of the airbags▷Keep at a distance from the airbags.▷Always grasp the steering wheel on the
steering wheel rim, holding your hands at
the 3 o'clock and 9 o'clock positions, to
keep the danger of injury to your hands or
arms as low as possible if the airbag is trig‐
gered.▷There should be no people, animals, or ob‐
jects between an airbag and a person.▷Do not use the cover of the front airbag on
the front passenger side as a storage area.▷Keep the dashboard and window on the
front passenger side clear, i.e., do not
cover with adhesive labels or coverings,
and do not attach holders such as for navi‐
gation instruments and mobile phones.▷Make sure that the front passenger is sit‐
ting correctly, i.e., keeps his or her feet and
legs in the footwell; otherwise, leg injuries
can occur if the front airbag is triggered.▷Do not place slip covers, seat cushions or
other objects on the front passenger seat
that are not approved specifically for seats
with integrated side airbags.▷Do not hang pieces of clothing, such as
jackets, over the backrests.▷Make sure that occupants keep their heads
away from the side airbag and do not rest
against the head airbag; otherwise, injuries
can occur if the airbags are triggered.▷Do not remove the airbag restraint system.▷Do not remove the steering wheel.▷Do not apply adhesive materials to the air‐
bag cover panels, cover them or modify
them in any way.▷Never modify either the individual compo‐
nents or the wiring in the airbag system.
This also applies to steering wheel covers,
the dashboard, the seats, the roof pillars
and the sides of the headliner.◀
Even when all instructions are followed closely,
injury from contact with the airbags cannot be
ruled out in certain situations.
The ignition and inflation noise may lead to
short-term and, in most cases, temporary
hearing impairment in sensitive individuals.
In the case of a malfunction, deactivation
and after triggering of the airbags
Do not touch the individual components imme‐
diately after the system has been triggered;
otherwise, there is the danger of burns.
Only have the airbags checked, repaired or dis‐
mantled and the airbag generator scrapped by
your service center or a workshop that has the
necessary authorization for handling explo‐
sives.
Non-professional attempts to service the sys‐
tem could lead to failure in an emergency or
undesired triggering of the airbag, either of
which could result in injury.◀
Warnings and information on the airbags are
also found on the sun visors.
Functional readiness of the airbag
system
When the ignition is switch on, the
warning lamp in the instrument cluster
lights up briefly and thereby indicates
the operational readiness of the entire airbag
system and the belt tensioner.
Airbag system malfunctioning
▷Warning lamp does not come on when the
ignition is turned on.▷The warning lamp lights up continuously.Seite 95SafetyControls95

NotePersonal responsibility
The system cannot possibly serve as a
substitute for the driver's personal judgment of
the traffic situation. The system may not al‐
ways detect critical situations reliably and in a
timely manner. Adapt speed to traffic situation
and drive alertly; otherwise, a risk to safety may
result.◀
Function
After the safety belt is buckled, the front belts
are automatically pretensioned once after the
vehicle is driven is away.
In critical driving situations, the following indi‐
vidual functions become active as needed:▷The front belts are automatically preten‐
sioned.▷Automatic closing of the windows.▷Automatic closing of the glass sunroof.
After a critical driving situation without an acci‐
dent, the front belts are loosened again. All
other systems can be restored to the desired
setting.
If the belt tension does not loosen automati‐
cally, stop the vehicle and unbuckle the belt
using the red button in the buckle. Fasten the
belt before continuing on your trip.
PostCrash
In the event of an accident, the system can
bring the car to a halt automatically without in‐
tervention by the driver in certain situations.
This can reduce the risk of a further collision
and the consequences thereof.
Depressing the brake pedal can cause the ve‐
hicle to brake harder. This interrupts automatic
braking. Depressing the accelerator pedal also
interrupts automatic braking.
After coming to a halt, the brake is released
automatically. Secure the vehicle against roll‐
ing.
