Seats, restraints53
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
3 115.
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.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 3 42.
Keep the area in which the airbag
inflates clear of obstructions.
