Safety
The seat belt system comprises:
R Seat belts
R Emergency Tensioning Devices for the
front seat belts and the outer seat belts in
the rear
R Seat belt force limiters
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
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 deceleration 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 bereplaced.
Important safety notes
The use of seat belts and child restraint sys-
tems is required by law in:
R all 50 states
R the U.S. territories
R the District of Columbia
R all 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
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
GWARNING
Persons under 5 ft (1.50 m) in height cannot
fasten the seat belt correctly without an addi- tional suitable restraint system. If the seat
belt is incorrectly fastened, it cannot protect
as intended. Furthermore, an incorrectly fas-
tened seat belt can cause additional injury, for
example, in an accident, during braking or an
abrupt change of direction. This poses an
increased risk of injury or even fatal injury.
For this reason, always secure persons under
5 ft (1.50 m) in height in suitable restraintsystems.
If a child younger than twelve years old and
under 5 ft (1.50 m) in height is traveling in the vehicle:
R always secure the child in a child restraint
system suitable for this Mercedes-Benz

immediately replaced at a qualified specialistworkshop.
If Emergency Tensioning Devices are trig-
gered or air bags are deployed, you will hear a bang, and a small amount of powder may also
be released. The 6restraint system warn-
ing lamp lights up.
Only in rare cases will the bang affect your
hearing. The powder that is released gener-
ally does not constitute a health hazard, but it
may cause short-term breathing difficulties in
people with asthma or other respiratory prob-
lems. To avoid this, you may wish to get out of
the vehicle or open the windows as soon as it is safe to do so.
Air bags and pyrotechnic Emergency Tension-
ing Devices (ETDs) contain perchlorate mate- rial, which may require special handling and
regard for the environment. National guide-
lines must be observed during disposal. In
California, see www.dtsc.ca.gov/
HazardousWaste/Perchlorate/
index.cfm .
Method of operation
During the first stage of a collision, the
restraint system control unit evaluates impor-
tant physical data relating to vehicle deceler- ation or acceleration, such as:
R duration
R direction
R intensity
Based on the evaluation of this data, the
restraint system control unit triggers the
Emergency Tensioning Devices during a fron- tal or rear collision.
An Emergency Tensioning Device can only be
triggered, if:
R the ignition is switched on
R the components of the restraint system are
operational; see "Restraint system warning lamp" ( Ypage 42)
R the belt tongue is engaged in the buckle on
the respective front-passenger seat The Emergency Tensioning Devices in the
rear compartment are triggered independ-
ently of the lock status of the seat belts.
If the restraint system control unit detects a
more severe accident, further components of
the restraint system are activated independ-
ently of each other in certain frontal collision
situations:
R Driver's air bag
R Front-passenger front air bag
The front-passenger front air bag is activated or deactivated depending on the person on
the front-passenger seat. The front-
passenger front air bag can only deploy in an
accident if the PASSENGER AIR BAG OFF indi- cator lamp is off. Observe the information on
the PASSENGER AIR BAG OFF indicator lamp ( Y page 43).
Your vehicle has a two-stage driver's air bag.
During the first deployment stage the driver's air bag fills with sufficient propellant gas to
reduce the risk of injuries. The front air bag is
fully deployed with the maximum amount of
propellant gas if a second deployment thresh- old is reached within a few milliseconds.
The activation threshold of the Emergency
Tensioning Devices and the air bag are deter- mined by evaluating the rate of vehicle decel-
eration or acceleration which occurs at vari-
ous points in the vehicle. This process is pre-
emptive in nature. Deployment should take
place in good time at the start of the collision.
The rate of vehicle deceleration or accelera-
tion and the direction of the force are essen- tially determined by:
R the distribution of forces during the colli-sion
R the collision angle
R the deformation characteristics of the vehi-
cle
R the characteristics of the object with which
the vehicle has collided
Factors which can only be seen and measured after a collision has occurred do not play a
decisive role in the deployment of an air bag.
