Seats, restraints41Airbag system
The 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.
Notice
Depending on the severity of a
collision, the fuel system may also be cut-off and the engine switched
off automatically, for safety reasons.
Resetting the fuel cut-off system;
refer to "Fuel system messages"
3 86.
Notice
Expiry dates for replacing the airbag system components may be found
on the label inside the glovebox.
Contact a workshop to have the
airbag system components
replaced.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 fix 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 might 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.
