A malfunction has occurred if the6restraint
system warning lamp:
Rdoes not light up after the ignition is switched
on
Rdoes not go out after a few seconds
Rgoes out but then lights up again while the
engine is running, for example
GWARNING
If restraint system is malfunctioning, restraint
system components may be triggered unin-
tentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emer- gency Tensioning Device or air bag, for exam-
ple. 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.
Seat belts
Introduction
A correctly fastened seat belt is the most effec- tive means of restraining the movement of vehi-
cle 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 thrown from
the vehicle. Furthermore, the seat belt helps to
keep the vehicle occupants in the best position
in relation to the air bag.
The seat belt system consists of:
RSeat belts
REmergency Tensioning Devices for the front
seat belts
If the vehicle is equipped with a front air bag,the seat belt system also includes a seat belt
force limiter for the corresponding seat.
On vehicles with a front-passenger bench
seat, only the seat belt of the outer front-
passenger seat has a seat belt force limiter.
If the vehicle does not have a driver's air bag, the
seat belt system does not include an Emergency
Tensioning Device or a seat belt force limiter.
If the seat belt is pulled quickly or suddenly from
the belt outlet, the inertia reel locks. The belt
strap cannot be pulled out further. Emergency Tensioning Devices tighten the seat
belts in an accident, pulling them close against
the occupant's body. They do not, howe
ver, pull
vehicle occupants back towards the backrest.
Emergency Tensioning Devices do not correct
an incorrect seat position or incorrectly worn
seat belts.
When triggered, the seat belt force limiter
reduces the force exerted by the seat belt on the
vehicle occupant.
The seat belt force limiters are synchronized
with the front air bags, which absorb part of the
deceleration force. This makes it possible to
reduce the forces to which vehicle occupants
are subjected during an accident.
The Emergency Tensioning Device of the co-
driver's seat is triggered independently of the
lock status of the seat belt.
Important safety notes
The use of seat belts and child restraint systems
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, in an 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 with 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 in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
40Occupant safety
Safety
If the restraint system control unit detects a side
impact situation, the applicable components of
the restraint system are deployed independ-
ently of each other. If the system determines a
need for additional protection for the vehicle
occupants, the Emergency Tensioning Devices
are also deployed.
RSide impact air bag on the side on which the
impact occurs, independently of the Emer-
gency Tensioning Device and of the use of the
seat belt
RWindow curtain air bag on the side of the col-
lision, regardless of seat belt use and whether
front-passenger seat is occupied
iNot all air bags are deployed in an accident.
The various air bag systems work independ-
ently of each other.
How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-
eration, and the apparent type of accident:
Rfrontal collision
Rside impact
Children in the vehicle
Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason, we
strongly advise that you install a child restraint
system on a rear seat. Children are generally
better protected there.
If a child younger than twelve years old and
under 5 ft (1.50 m)in height is traveling in the
vehicle:
Ralways secure the child in a child restraint
system suitable for this vehicle. The child
restraint system must be appropriate to the
age, weight and size of the child
Rbe sure to observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's installation
instructions
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
GWARNING
If persons, particularly children are subjected to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
GWARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight. Pro- tect it with a blanket, for example. If the child
restraint system has been exposed to direct
sunlight, let it cool down before securing the
child in it. Never leave children unattended in
the vehicle.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sitting
properly. Particular attention must be paid to
children.
Observe the safety notes on the seat belt
(
Ypage 40) and the notes on correct use of seat
belts (Ypage 41).

Child restraint system on the front-
passenger seat
General notes
Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install
the child restraint system on a rear seat.
Rearward-facing child restraint system
The front-passenger front air bag cannot be
deactivated. Always install a rearward-facing
child restraint system on a suitable rear seat.
Always observe the child restraint system man-
ufacturer's installation and operating instruc-
tions.
Forward-facing child restraint system
If it is absolutely necessary to install a forward-
facing child restraint system on the front-
passenger seat, always move the front-
passenger seat as far back as possible. The
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the child
restraint system must lie as flat as possible
against the backrest of the front-passenger
seat. The child restraint system must not be
subjected to a load by the head restraint. Adjust
the head restraint position accordingly. Always
make sure that the shoulder belt strap is cor-
rectly routed from the vehicle belt outlet to the
shoulder belt guide on the child restraint sys-
tem. The shoulder belt strap must be routed for-
wards and downwards from the vehicle belt out-
let. If necessary, adjust the vehicle belt outlet
and the front-passenger seat accordingly.
Always observe the child restraint system man-
ufacturer's installation and operating instruc-
tions.

the vehicle in the event of an accident or sud-
den steering or braking, thereby injuring vehi- cle occupants. There is a risk of an accident
and injury.
Never leave animals unattended in the vehi-
cle. Always secure animals properly during
the journey, e.g. use a suitable animal trans-
port box.
Driving safety systems
Overview
In this section, you will find information about
the following driving safety systems:
RABS (Anti-lock Braking System)
RASR (Acceleration SkidControl)
RBAS (B rakeAssist System)
REBD (E lectronic Brake Force Distribution)
RESP®(Electronic StabilityProgram)
Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of accident nor override the
laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for the distance to the vehicle in
front, for vehicle speed, braking in good time
and for staying in your lane. Always adapt your
driving style to the prevailing road and weather
conditions and maintain a sufficient, safe dis-
tance from other road users. Drive carefully.
Please note that the driving safety systems
described only work optimally when:
Rthere is adequate contact between the tires
and the road surface
Ryou use winter tires (M+S tires), with snow
chains if necessary, when the road conditions
are wintry.
