Description and function of the airbags
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The airbags can protect vehicle occupants during frontal and side collisions by reducing their
movement in the direction of the collision.
When an airbag is triggered, it is inflated by a gas generator. This causes the airbag covers to
break, and the airbags inflate forcefully to cover their deployment zones within milliseconds. Once a
vehicle occupant wearing a seat belt starts to sink into the inflated airbag, the gas inside the airbag
starts to escape to cushion the occupant and slow down their movement. This can reduce the risk
of severe and fatal injuries. A triggered airbag will not always prevent other injuries from occurring,
such as swelling, bruising, burning and grazing. The deployment of the airbag can also produce
frictional heat.
Airbags provide no protection for the arms or lower body. Exception: in vehicles with a knee airbag,
the knee area of the driver will be protected.
The most important factors for triggering the airbag are the type of accident, the angle of impact,
the vehicle speed and the type of object with which the vehicle collides. Therefore, visible damage
to the vehicle does not always mean that the airbag should have been triggered.
Whether or not the airbag triggers is determined by the vehicle deceleration rate caused by the
collision and registered by the electronic control unit. If this rate is below the reference value
programmed into the control unit, the airbags will not be triggered, even though the vehicle may be
badly damaged as a result of the collision. Vehicle damage, repair costs or even the lack of vehicle
damage in an accident do not necessarily give an indication of whether an airbag should inflate or
not. It is not possible to define a range of vehicle speeds and reference values, since the
circumstances will vary considerably between one collision and another. It is therefore impossible to
cover every possible kind and angle of impact that would trigger the airbags. Important factors in
the triggering of the airbag include the nature (hard or softyf R I W K H R E M H F W W K D W W K H Y H K L F O H K L W V W K H
angle of impact, and the vehicle speed.
Airbags only serve as a supplement to the three-point seat belt in some accident situations when
the vehicle braking is sufficient to trigger the airbags. Airbags can only be triggered once and only
in certain situations. The seat belts are always there to provide protection in situations in which the
airbags are not triggered or have already been triggered. For example, if the vehicle collides with a
further vehicle following the initial collision, or is hit by another vehicle.
The airbag system is part of the vehicle's overall passive safety concept. The airbag system can
only work effectively when the occupants are wearing their seat belts correctly and have assumed a
proper sitting position ⇒ Sitting position.
Components of the vehicle safety concept
The following vehicle safety equipment makes up the vehicle's safety concept to reduce the risk of
severe and fatal injuries. Some of this equipment may not be fitted in your particular vehicle. It may
not be available at all in some countries.
•Optimised seat belts for all seats.
•Belt tensioners for the driver and front passenger and also on the rear outer seats if in
conjunction with side airbags.
•Belt tension limiter for the driver, front passenger and, if applicable, for the rear outer seats.
•Belt height adjuster for the front seats.
•Warning lamp and belt status display.
•Front airbags for driver and front passenger.
•Side airbags for the driver, front passenger and, if applicable, for the rear outer seats.
•Curtain airbags on the left and right.
•If applicable, knee airbag for the driver.
•Airbag indicator lamp .
•Indicator lamp PASSENGER AIR BAG in the upper section of the centre console.
•Indicator lamp PASSENGER AIR BAG in the upper section of the centre console.
•Control units and sensors.
•Whiplash-optimised and height-adjustable head restraints.
•Adjustable steering column.
•If applicable, anchor points for child seats on the rear outer seats and on the front passenger
seat.
•If applicable, securing points for the top tether for child seats.
Situations when the front, knee, side and curtain airbags will not be
triggered:
•If the ignition is switched off during a collision.
•If the level of deceleration measured by the control unit is too low during a collision at the front
of the vehicle.
•During a minor side collision.
•During rear collisions.
Switching the front passenger front airbag on and off
Fig. 46 In the dash panel on the front passenger side or in the stowage compartment: key-operated
switch for switching the front passenger front airbag on and off.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The front passenger front airbag must be disabled if you fit a rear-facing child seat to the
front passenger seat.
Enabling the front passenger front airbag
•Switch off the ignition.
•Open the door on the front passenger side.
•Fold the key bit of the vehicle key all the way out ⇒ Vehicle key set.
•Insert the fully folded-out key bit of the vehicle key into the key-operated switch in the dash
panel ⇒ Fig. 46 to the second point of resistance. Around three quarters of the key bit should
be inserted in the key switch at this point ⇒.
•Turn the vehicle key, without applying force, to the position.
•Remove the vehicle key from the key-operated switch and fold away the key bit ⇒.
•The indicator lamp PASSENGER AIR BAG in the upper part of the centre console
lights up and goes out after approximately 60 seconds ⇒ Indicator lamp.
•Close the door on the front passenger side.
•Check that the PASSENGER AIR BAG indicator lamp in the upper section of the
centre console does not light up when the ignition is switched on ⇒ Indicator lamp.
Disabling the front passenger front airbag
•Switch off the ignition.
•Open the door on the front passenger side.
•Fold the key bit of the vehicle key all the way out ⇒ Vehicle key set.
•Insert the fully folded-out key bit of the vehicle key into the key-operated switch in the dash
panel ⇒ Fig. 46 to the second point of resistance. Around three quarters of the key bit should
be inserted in the key switch at this point ⇒.
•Turn the vehicle key, without applying force, to the position.
•Remove the vehicle key from the key-operated switch and fold away the key bit ⇒.
•Close the door on the front passenger side.
•When the ignition is switched on, the indicator lamp PASSENGER AIR BAG will light
up steadily in the upper section of the centre console ⇒ Indicator lamp.
Ensuring that the front passenger front airbag has been deactivated
The only sure sign that the front passenger front airbag has been deactivated is when the
PASSENGER AIR BAG indicator lamp is displayed continuously in the upper section of
the centre console ( lights up yellow steadilyyf ⇒ Indicator lamp.
If the indicator lamp PASSENGER AIR BAG in the upper section of the centre console is
not lit up steadily, or if it lights up together with the indicator lamp in the instrument cluster,
do not attach any child restraint system to the front passenger seat for safety reasons. The front
passenger front airbag may trigger during an accident.
Side airbags

Fig. 48 On the side of the front seat: location and deployment zone of the side airbag.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Depending on the vehicle equipment level, side airbags may also be fitted for the front seats and
rear outer seats ⇒ Fig. 47.
•The side airbags for the front seats are located in the outer seat backrest cushions of the driver
seat and front passenger seat ⇒ Fig. 48.
•If fitted, the side airbags for the rear outer seats are each located between the door entry and
the individual rear seat backrests.
The side airbag locations are identified by the text AIRBAG.
The areas inside the red lines ⇒ Fig. 47 and ⇒ Fig. 48 are covered by the side airbags when
triggered (deployment zonesyf <
