In the event of an accident, people
not wearing seat belts endanger their fellow occupants and
themselves.

tachometer 3 113 and for passenger
seat in the centre console 3 111.
Belt force limiters
On the front seats, stress on the body is reduced by the gradual release of
the belt during a collision.
Belt pretensionersIn the event of a head-on or rear-endcollision 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.

pretensioners can only be triggered
once.

other objects that may interfere with
the operation of the belt
pretensioners. Do not make any
modifications to belt pretensioner components as this will invalidate
