the following points. You must make sure of
this both before and during a journey.

Depending on the build of the person on the
front-passenger seat, the PASSENGER AIR
BAG OFF indicator lamp may light up. The
front-passenger front airbag is disabled. It
will then not be deployed in the event of an
accident. In this case, the front-passenger
seat should not be used.
It is imperative to observe the notes on the
"Automatic front-passenger front airbag
deactivation system" (
as on "Seat belts" (

Seat belts
Introduction
A correctly worn seat belt is the most effec-
tive means of restraining the movement of

vehicle occupants in the event of a collision or
if the vehicle overturns. This reduces the risk
of vehicle occupants coming into contact with
parts of the vehicle interior or being ejected
from it. The seat belt also helps to keep the
vehicle occupants in the best position in rela-
tion to the airbag being deployed.
The seat belt system consists of:
seat belts
R
belt tensioners for the front seat belts and
R
the outer seat belts in the rear
belt force limiters for the front seat belts
R
and the outer seat belts in the rear
If the seat belt is pulled quickly or sharply
from the belt outlet, the inertia reel locks. The
belt strap cannot be pulled out any further.
The belt tensioner tightens the seat belt in the
event of a collision so that it fits tightly across
your body. However, it does not pull the vehi-
cle occupants back in the direction of the seat
backrest.
The belt tensioner does not, however, correct
an incorrect seat position or correct the rout-
ing of a seat belt that is worn incorrectly.
When triggered, seat belt force limiters help
to reduce the peak force exerted by the seat
belt on the vehicle occupant.
The belt force limiters on the front seats are
synchronised with the front airbags, which
take on a part of the deceleration force. This
can reduce the forces to which the vehicle
occupants are subjected during an accident.
! If the co-driver's seat is not occupied, do
not engage the seat belt tongue in the
buckle on the co-driver's seat. Otherwise,
the belt tensioner could be triggered in the
event of an accident and would have to be
replaced.
