PASSENGER AIR BAG OFF indicator
lamp
PASSENGER AIR BAG OFF indicator lamp :is
part of the BabySmart™ air bag deactivation
system.
Ap ermanently 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 ajourney.
RChildren in achild 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 49). There you will also find instruc-
tions on rearward and forward-facingc hild
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 43). There you can also find infor-
mation on the corrects eat 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
If the seat belt is pulled out at the belt sash guide
quickly or with ajerk ym ovement ,the belt
retractor locks. The belt strap cannot be extrac-
ted any further.
The Emergency Tensioning Device tighten sthe
seat belt in an accident,p ulling the belt close
against the body. However it does not pull the
vehicle occupant back in the direction of the
backrest.
The Emergency Tensioning Device does not cor-
rect an incorrect seat position or the routing of
an incorrectly fastened seat belt.
When triggered, aseat belt force limiter helps to
reduce the force exerted by the seat belt on the
vehicle occupant.
The seat belt force limiters for the front seats are
synchronized with the front air bags, which
absorb part of the deceleration force. This can
reduce the force exerted on the vehicle occu-
pants during an accident.
!If the front-passenger seat is unoccupied,
do not insert the belt tongue into the buckle of
the front-passenger seat. This may otherwise
lead to the triggering of the Emergency Ten-
sioning Device in the event of an accident,
which will then need to be replaced.

Proper use of the seat belts
Observe the safety notes on the seat belt
(Ypage 40).
All vehicle occupants must be wearing the seat
belt correctly before beginning the journey. Also
make sure that all vehicle occupants are always
wearing the seat belt correctly while the vehicle
is in motion.
When fastenin gthe seat belt, always make sure
that:
Rthe seat belt buckle tongue is inserted only
into the belt buckle belonging to that seat.
Rthe seat belt is pulled tight across your body.
Avoid wearing bulky clothing, e.g. awinter
coat.
Rthe seat belt is not twisted.
Only then can the forces which occur be dis-
tributed over the area of the belt.
Rthe shoulder section of the belt is routed
across the center of your shoulder.
The shoulder section of the seat belt should
not touch your neck or be routed under your
arm or behind your back. Where possible,
adjust the seat belt to the appropriate height.
Rthe lap belt is taut and passes across your lap as low down as possible.
The lap belt must always be routed across
your hip jointsa nd not across your abdomen.
This appliesp articularly to pregnant women.
If necessary, push the lap belt down to your
hip joint and pull it tight using the shoulder
section of the belt.
Rthe seat belt is not routed across sharp, poin-
ted or fragile objects.
If you have such items located on or in your
clothing, e.g. pens, keys or eyeglasses, store
these in asuitable place.
Ronly one person is using aseat belt.
Infantsa nd children must never travel sitting
on the lap of avehicle occupant. In the event
of an accident, they could be crushed
between the vehicle occupant and seat belt.
Robject sare never secured with aseat belt if
the seat belt is also being used by one of the
vehicle's occupants.
Also ensure that there are never objects
between aperson and the seat, e.g. cushions.
Seat belts are only intended to secure and
restrain vehicle occupants. Always observe the
"Loading guidelines" for securing objects, lug-
gage or loads (
Ypage 204).
Fastening and adjusting the seat belts
Observe the safety notes on the seat belt
(Ypage 40) and the notes on correct use of seat
belts (Ypage 41).
If the center rear seat belt is being used, also
observe the information about the seat belt for
the center rear seat (
Ypage 42).

RAdjust the seats properly before beginning
your journey. Always make sure that the seat
is in an almost upright position. The center of
the head restraint must support the head at
about eye level.
RMove the driver's and front-passenger seats
as far back as possible. The driver's seat posi-
tion must allow the vehicle to be driven safely.
ROnly hold the steerin gwheel on the outside.
This allows the air bag to be fully deployed.
RAlways lean against the backrest while driv-
ing. Do not lean forwards or lean against the
door or side window. You may otherwise be in
the deployment area of the air bags.
RAlways keep your feet in the footwell in front
of the seat. Do not put your feet on the dash-
board, for example. Your feet may otherwise
be in the deployment area of the air bag.
RFor this reason, alwayss ecure persons less

Devicesa nd air bags
Important safety notes
GWARNING
The air bag parts are hot after an air bag has
been deployed. There is arisk of injury.
Do not touch the air bag parts. Have a
deployed air bag replaced at aqualified spe-
cialist workshop as soon as possible.
GWARNING
Ad eployed air bag no longer offers any pro-
tection and cannot provide the intended pro-
tection in an accident .There is an increased
risk of injury.
Have the vehicle towed to aqualified special-
ist workshop in order to have adeployed air
bag replaced.
It is importan tfor your safety and that of your
passenger to have deployed air bags replaced
and to have any malfunctioning air bags
repaired. This will help to make sure the air bags
continue to perform their protective function for
the vehicle occupantsint he event ofacrash.
GWARNING
Emergency TensioningD evices that have
deployed pyrotechnically are no longer opera-
tional and are unable to perform their inten-
ded protective function. This poses an
increased risk of injury or even fatal injury.
Have pyrotechnically triggered Emergency
TensioningD evices replaced immediately at a
qualified specialist workshop.
If Emergency TensioningD evices are triggered
or air bags are deployed, you will hear abang,
and asmall amount of powder may also be
released. The 6restraint system warning
lamp lights up.
Only in rare cases will the bang affect your hear-
ing. The powder that is released generally does
not constitut eahealth hazard, but it may cause
short-term breathing difficulties in people with
asthma or other respiratory problems. Provided
it is safe to do so, you should leave the vehicle
