regular intervals while the engine is running.
Therefore, malfunctions can be detected in
good time.
The6 restraint system warning lamp on the
instrument cluster lights up when the ignition is
switched on. It goes out no later than a few sec-
onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
A malfunction has occurred if the 6restraint
system warning lamp:
Rdoes not light up after the ignition is switched
on
Rdoes not go out after a few seconds with the
engine running
Rlights up again while the engine is running
GWARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This can affect
for example the Emergency Tensioning
Device or the air bag. This poses an increased
risk of injury or even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.
PASSENGER AIR BAG OFF indicator
lamp
PASSENGER AIR BAG OFF indicator lamp :is
part of the BabySmart™ air bag deactivation
system.
A permanently lit PASSENGER AIR BAG OFF
indicator lamp informs you that the front-
passenger front air bag is deactivated. Depending on the person in the front-passenger
seat, the front-passenger front air bag must
either be deactivated or enabled; see the fol-
lowing points. You must make sure of this both
before and during a journey.
RChildren in a child restraint system:
whether the front-passenger front air bag is
enabled or deactivated depends on the instal-
led child restraint system, and the age and
size of the child. Therefore, always observe
the information on "Children in the vehicle"
(
Ypage 50). There you will also find instruc-
tions on rearward and forward-facing child
restraint systems on the front-passenger
seat.
RAll other persons: the PASSENGER AIR BAG
OFF indicator lamp must be off. Be sure to
observe the notes on "Seat
belts“ (
Ypage 39) and "Air bags"
(Ypage 44). There you can also find infor-
mation on the correct seat position.
Observe the information on the BabySmart™ air
bag deactivation system in the front-passenger
seat (
Ypage 53).
Seat belts
Introduction
Seat belts are the most effective means of
restricting the movement of vehicle occupants
in the event of an accident or the vehicle rolling
over. This reduces the risk of vehicle occupants
coming into contact with parts of the vehicle
interior or being ejected from the vehicle. Fur-
thermore, the seat belt helps to keep the vehicle
occupant in the best position in relation to the
air bag.
The seat belt system comprises:
RSeat belts
REmergency Tensioning Devices for the front
seat belts and the outer seat belts in the rear
RSeat belt force limiters for the front seat belts
and the outer seat belts in the rear
If the seat belt is pulled out at the belt sash guide
quickly or with a jerky movement, the belt
retractor locks. The belt strap cannot be extrac-
ted any further.
The Emergency Tensioning Device tightens the
seat belt in an accident, pulling the belt close
against the body. However it does not pull the
