Occupant safety
Introduction to the restraint system
The restraint system can reduce the risk of
vehicle occupants coming into contact with
parts of the vehicle's interior in the event of
an accident. The restraint system can also reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system comprises:
RSeat belt system
RAir bags
RChild restraint system
RChild seat securing systems
The components of the restraint system work in conjunction with each other. They can only
deploy their protective function if, at all times,
all vehicle occupants:
Rhave fastened their seat belts correctly
(
Ypage 47)
Rhave adjusted their seat and head restraint
properly (
Ypage 107).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the cor-
rect driver's seat position (
Ypage 106).
You also have to make sure that an air bag can inflate properly if deployed (
Ypage 50).
An air bag supplements a correctly worn seat
belt. As an additional safety device, the air
bag increases the level of protection for vehi-
cle occupants in the event of an accident. For
example, if, in the event of an accident, the
protection offered by the seat belt is suffi-
cient, the air bags are not deployed. When an
accident occurs, only the air bags that
increase protection in that particular accident
situation are deployed. However, seat belts
and air bags generally do not protect against objects penetrating the vehicle from the out-
side.
Information on restraint system operation
can be found under "Triggering of the Emer-
gency Tensioning Devices and air bags"
(
Ypage 59).
For more information about children traveling
with you in the vehicle and on child restraint
systems, see "Children in the vehicle"
(
Ypage 62).

Restraint system warning lamp
The functions of the restraint system are
checked after the ignition isswitched on and
at regular intervals while the engine is run-
ning. Therefore, malfunctions can bedetec-
ted ingood time.
The 6 restraint system warning lamp in
the instrument cluster lights up when the igni-
tion is swit ched on. Itgoes out no later than a
few seconds after the vehicle is started. The
components of the restraint system are in
operational readiness.
A malfunction has occurred if the 6
restraint system warning lamp:
Rdoes not light up after the ignition is
swit ched on
Rdoes not go out after a few seconds with
the engine running
Rligh ts up again while the engine is running

PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG OFF indicator lamp :
and PASS ENGER AIR BAG ON indicator
lamp ;are part of the Occupant Classific a-
tion System (OCS).
The indicator lamps display the status of the
front-passenger front air bag.
RPASS ENGER AIR BAG ON lights up: the
front-passenger front air bag isenabled. If,
in the event of an acc ident, all deplo yment
cr iteria are met, the front-passenger front
air bag is deplo yed.
RPASSENGER AIR BAG OFF lights up: the
front-passenger front air bag isdeactiva-
te d. It will then not be deployedinthe event
of an accident.
Depending on the person inthe front-
passenger seat, the front-passenger front air
bag must either bedeactivated or enabled;
see the following points. You must make sure
of th isboth before and during a journey.
RChildren in a child res traint system:
whether the front-passenger front air bag is
enabled or deactivated depends on the
installed ch ildrestraint system, and the age

and size of the child. Therefore, be sure to
observe the notes on the "Occupant Clas-
sification System (OCS)" (
Ypage 53) and
on "Children in the vehicle" (
Ypage 62).
There you will also find instructions on rear-
ward and forward-facing child restraint sys- tems on the front-passenger seat.
RAll other persons: depending on the clas-
sification of the person in the front-
passenger seat, the front-passenger front
air bag is enabled or deactivated
(
Ypage 53). Be sure to observe the notes
on "Seat belts“ (
Ypage 46) and "Air bags"
(
Ypage 50). There you can also find infor-
mation on the correct seat position.
Seat belts
Introduction
Seat belts are the most effective means of
restricting the movement of vehicle occu-
pants in the event of an accident or the vehi-
cle rolling over. This reduces the risk of vehi-
cle occupants coming into contact with parts
of the vehicle interior or being ejected from
the vehicle. Furthermore, the seat belt helps
to keep the vehicle occupant in the best posi-
tion in relation to the air bag.
The seat belt system comprises:
RSeat belts
REmergency Tensioning Devices and seat
belt force limiters
If the seat belt is pulled by the seat belt
extender quickly or with a jerky movement,
the belt retractor locks. The belt strap cannot
be extracted 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 vehicle occupant back in the direction
of the backrest.
The Emergency Tensioning Device does not
correct an incorrect seat position or the rout-
ing of an incorrectly fastened seat belt. When triggered, a seat 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 dec elerat
ion force.
This can reduce the force exerted on the vehi-
cle occupants 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 oth-
erwise lead to the triggering of the Emer-
gency Tensioning Device in the event of an
accident, which will then need to be
replaced.
Important safety notes
The use of seat belts and child restraint sys-
tems is required by law in:
Rall 50 states
Rthe U.S. territories
Rthe District of Columbia
Rall Canadian provinces
Even where this is not required by law, all
vehicle occupants should correctly fasten
their seat belts before starting the journey.
GWARNING
If the seat belt is incorrectly fastened, it can-
not protect as intended. Furthermore, an
incorrectly fastened seat belt can cause addi-
tional injury, for example, inan accident, dur-
ing braking or when abruptly changing direc-
tion. This poses an increased risk of injury or
even fatal injury.
Make sure that all vehicle occupants are
seated properly wit h a correctly fastened seat
belt .
GWARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or inthe event of an accident, you could
slide underneath the seat belt and sustain
