52Seats, restraintsAirbag systemThe airbag system consists of a
number of individual systems
depending on the scope of
equipment.
When triggered, the airbags inflate
within milliseconds. They also deflate
so quickly that it is often unnoticeable during the collision.9 Warning
If handled improperly the airbag
systems can be triggered in an
explosive manner.
Notice
The airbag systems and belt
pretensioner control electronics are
located in the centre console area.
Do not put any magnetic objects in
this area.
Do not affix any objects onto the
airbag covers and do not cover them with other materials.
Each airbag is triggered only once.
Have deployed airbags replaced by
a workshop. Furthermore, it may be
necessary to have the steering
wheel, the instrument panel, parts of
the panelling, the door seals,
handles and the seats replaced.
Do not make any modifications to
the airbag system as this will
invalidate the vehicle type approval.
When the airbags inflate escaping hot gases may cause burns.
Control indicator v for airbag systems
3 114.
Front airbag system The front airbag system consists of
one airbag in the steering wheel and
one in the instrument panel on the
front passenger side. These can be
identified by the word AIRBAG.
Additionally, there is a warning label
on the side of the instrument panel,
visible when the front passenger door
is open, or on the front passenger sun visor.
The front airbag system is triggered in
the event of a front-end impact of a
certain severity. The ignition must be
switched on.
Page 55 of 343

Seats, restraints53
The inflated airbags cushion the
impact, thereby reducing the risk of
injury to the upper body and head of
the front seat occupants
considerably.
9 Warning
Optimum protection is only
provided when the seat is in the
proper position.
Seat position 3 39.
Keep the area in which the airbag
inflates clear of obstructions.
Fit the seat belt correctly and
engage securely. Only then is the
airbag able to protect.
Side airbag system
The side airbag system consists of an
airbag in each front seat backrest.
This can be identified by the word
AIRBAG .
The side airbag system is triggered in the event of a side impact of a certain
severity. The ignition must be
switched on.
The inflated airbags cushion the
impact, thereby reducing the risk of
injury to the upper body and pelvis in
the event of a side-on collision
considerably.
9 Warning
Keep the area in which the airbag
inflates clear of obstructions.
Notice
Only use protective seat covers that
have been approved for the vehicle.Be careful not to cover the airbags.
