belt. If the vehicle is stationary and a door is
opened, the 7 seat belt warning lamp
goes out and the warning tone ceases.
For certain countries only: regardless of
whether the driver or the front passenger
have fastened their seat belts, the 7 seat
belt warning lamp lights up for 6 seconds
after the engine is started. It then goes out
once the driver and the front passenger have
fastened their seat belts.

countries.
Belt tensioners, belt force limiters
The seat belts are fitted with belt tensioners.
!
If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in
the buckle on the front-passenger seat.
Otherwise, the belt tensioner could be trig-
gered in the event of an accident.
The belt tensioners tighten the seat belts in
an accident, pulling them close against the
body.
Belt tensioners do not correct incorrect seat
positions or incorrectly fastened seat belts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
If the seat belt is also fitted with a belt force
limiter and this is triggered, the force exerted
by the seat belt on the vehicle occupant is
reduced.
The front belt force limiters are synchronised
with the front airbags, which take on a part of
the deceleration force. Thus, the force exer-
ted on the occupant is distributed over a
greater area.
The belt tensioners can only be activated
when:
the ignition is switched on
R
the restraint systems are operational; see

The belt tensioners are triggered depending
