System descriptionRead and observe
on page 14 first.
The inflation of the airbag is carried out in a fraction of a second.
When the airbags are deployed they fill with gas and inflate.
A grey white or red, non-harmful gas is released when the airbag is inflated.
This is perfectly normal and is not an indication of a fire in the vehicle.
Depending on the vehicle equipment, the airbag system consists of the
following parts. ▶ Front airbag for the driver and the front passenger » page 15.
▶ Driver’s knee airbag » page 17.
▶ Side airbags » page 17.
▶ Head airbags » page 18.
▶ Airbag warning light in the instrument cluster » page 35.
▶ Key switch for the front passenger airbag » page 19.
▶ Warning light for the front passenger airbag in the middle of the dash panel
» page 19 .
Airbag deployment
Read and observe
on page 14 first.
The airbag system is only functional when the ignition is switched on.
Triggering conditions
It is not possible to generally determine which deployment conditions apply to
the airbag system in every situation. An important role is played by factors
such as the type of object that the vehicle hits (hard/soft), the impact angle, vehicle speed, etc.
A decisive factor for the deployment of the airbags is the deceleration which
occurs. If the vehicle deceleration which occurs and is measured during the
collision remains below the prescribed reference values specified in the control
unit, the airbags are not deployed although the vehicle may well suffer severe
damage to the bodywork as a consequence of the accident.
The following airbags will be deployed in the event of a severe frontal
collision.
▶ Driver’s front airbag.
▶ Front passenger airbag.
▶ Driver’s knee airbag.
The following airbags will be deployed in the event of a severe side collision.
▶ Front side airbag on the side of the accident.
▶ Rear side airbag on the side of the accident.
▶ Head airbags on the side of the accident.
When an airbag is deployed, the following occurs.
▶ The interior light comes on (if the automatic operation of the interior light is
switched on - switch
).
▶ The hazard warning lights are switched on.
▶ All the doors are unlocked.
▶ The fuel supply to the engine is interrupted.
When there is no air bag deployment?
With minor frontal and side collisions, rear collision, overturning of the vehicle
or vehicle roll-over there is no airbag deployment.

▶ The exterior mirrors are folded back into the park position.
▶ The anti-theft alarm system is activated.
If the doors or the luggage compartment lid remain open after the vehicle has
been locked, the turn signal lights do not flash until they have been closed.
Protection against unwanted vehicle unlocking
If the vehicle is unlocked and a door or the boot lid not opened within the next
45 seconds, the vehicle will lock again automatically and the safe securing sys-
tem or anti-theft alarm system will be switched back on.WARNING■ Never leave the key in the vehicle when you exit the vehicle. Unauthor-
ized persons, such as children, for example, could lock the car, turn on the
ignition or start the engine - there is a danger of injury and accidents!■
When leaving the vehicle, never leave persons who are not completely in-
dependent, such as children, unattended in the vehicle. These individuals
might not be able to leave the vehicle on their own or to help themselves.
Can be fatal at very high or very low temperatures!
CAUTION
■ Each key contains electronic components; therefore it must be protected
against moisture and severe shocks.■
Keep the groove of the keys absolutely clean. Impurities (textile fibres, dust,
etc.) have a negative effect on the functionality of the locking cylinder and ig-
nition lock.
■
If the driver's door has been opened, the vehicle cannot be locked.

Rear mirror
Introduction
This chapter contains information on the following subjects:
Interior mirror dimming
79
Exterior mirrors
80WARNING■ Convex (curved outward) or aspheric exterior mirrors increase the field of
vision. They do, however, make objects appear smaller in the mirror. These
mirrors are therefore only of limited use for estimating distances to the fol-
lowing vehicles.■
Whenever possible use the interior mirror for estimating the distances to
the following vehicles.
WARNINGThe mirrors with automatic dimming contain an electrolyte liquid which can
escape if mirror glass is broken.■
The leaking electrolytic fluid can irritate the skin, eyes and breath appara-
tus.
■
If your eyes or skin come into contact with the electrolytic fluid, immedi-
ately wash the affected area for a few minutes long with a lot of water. If
necessary get medical assistance.

Mirror with automatic dimming
If the automatic dimming is enabled, the mirror dims automatically depending
on the light falling on the sensors.
When the interior lights are switched on or the reverse gear is engaged, the
mirror always moves back into the basic position (not dimmed).
Do not attach external devices (e.g. navigation systems) on to the windscreen
or in the vicinity of the interior mirror »
.
WARNING■
The illuminated display of an external navigation device can lead to op-
erational faults to the automatic dimming interior mirror – risk of accident.■
The automatic dimming mirror only functions smoothly if the light falling
on the sensors is not impaired, e.g. by the rear sun roller blind.
