Seats, restraints39Seat belts
The seat belts are locked during
heavy acceleration or deceleration of
the vehicle holding the occupants in
the sitting position. Therefore the risk
of injury is considerably reduced.
9 Warning
Fasten seat belt before each trip.
In the event of an accident, people
not wearing seat belts endanger their fellow occupants and
themselves.
Seat belts are designed to be used by only one person at a time. Child
restraint system 3 47.
Periodically check all parts of the belt
system for damage, pollution and
proper functionality.
Have damaged components replaced by a workshop. After an accident,
have the belts and triggered belt
pretensioners replaced by a
workshop.
Note
Make sure that the belts are not
damaged by shoes or sharp-edged objects or trapped. Prevent dirt from getting into the belt retractors.

belt reminder, indicated for driver seat
as control indicator X in the
tachometer 3 72, and for front
passenger seat as control indicator
k in the Driver Information Centre
3 69.Belt force limiters
Stress on the body is reduced by the
gradual release of the belt during a
collision.
Belt pretensioners
In the event of a head-on or rear-end
collision of a certain severity, the front
seat belts are tightened.9 Warning
Incorrect handling (e.g. removal or
fitting of belts) can trigger the belt
pretensioners.
Deployment of the belt pretensioners
is indicated by continuous illumination
of control indicator v 3 72.
Triggered belt pretensioners must be replaced by a workshop. Belt
pretensioners can only be triggered
once.

Airbag 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.9 Warning
If handled improperly the airbag
systems can be triggered in an
explosive manner.
Note
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. Have damaged
covers replaced by a workshop.
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.
Fault
If there is a fault in the airbag system, the control indicator v illuminates and
a message or a warning code
appears in the Driver Information
Centre. The system is not
operational.
Have the cause of the fault remedied by a workshop.
