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
vehicle 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
position 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
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 direc-
tion of the backrest.
The Emergency Tensioning Device does not
correct an incorrect seat position or the
routing 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 are synchronized
with the front air bags which absorb part of
the deceleration force. This can reduce the
force exerted on the vehicle occupants during
an accident.
!If the front-passenger seat is unoccu-
pied, do not insert the belt tongue into the
buckle of the front-passenger seat. This
may otherwise lead to the triggering of the
Emergency 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
cannot protect as intended. Furthermore,
an incorrectly fastened seat belt can cause
additional injury, for example, in an acci-
dent, during braking or when abruptly
changing direction. 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 backrest to an almost vertical position.
When braking 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 back-
rest is in an almost vertical position and
that the shoulder section of your seat belt
is routed across the center of your shoul-
der.
GWARNING
Persons under 5 ft (1.50 m)in height cannot
fasten the seat belt correctly without an
additional suitable restraint system. If
the seat belt is incorrectly fastened, it
cannot protect as intended. Furthermore,
an incorrectly fastened seat belt can cause

facing child restraint system must lie as flat
as possible against the backrest of the front-
passenger seat.
The child restraint system must not touch the
roof. Adjust the backrest angle accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint
system manufacturer's installation instruc-
tions.
How the occupant classification system
(OCS) operates
0043PASSENGER AIR BAG OFF indicator lamp
0044PASSENGER AIR BAG ON indicator lamp
The indicator lamps indicate whether the
front-passenger front air bag is activated or
deactivated.
XTurn the key to position 1or 2in the igni-
tion lock.
The system carries out a self-diagnosis
test.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up
simultaneously for about six seconds.
The indicator lamps then display the status of
the front-passenger front air bag:
RPASSENGER AIRBAG ON lights up: the front-
passenger front airbag is enabled. If, in
the case of an accident, all deployment cri-
teria are met, the front-passenger front
air bag is deployed.
RPASSENGER AIRBAG OFF lights up: the front-
passenger front airbag is disabled. It will then not be deployed in the event of an
accident.
Always observe the PASSENGER AIR BAG ON and
PASSENGER AIR BAG OFF indicator lamps when
the front-passenger seat is occupied. Make
sure that the status of the front-passenger front air bag is correct before and during a
journey.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air
bag is disabled. It will not be deployed in
the event of an accident and cannot perform
its intended protective function. A person
in the front-passenger seat could then, for
example, come into contact with the vehi-
cle's interior, especially if the person is
sitting too close to the dashboard. This
poses an increased risk of injury or even
fatal injury.
When the front-passenger seat is occupied, always ensure that:
Rthe classification of the person in the
front-passenger seat is correct and the
front-passenger front air bag is enabledor disabled in accordance with the per-
son in the front-passenger seat
Rthe front-passenger seat has been movedback as far back as possible.
Rthe person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front air bag is correct.
GWARNING
If you secure a child in a rearward-facing
child restraint system on the front-
passenger seat and the PASSENGER AIR BAG
ON indicator lamp is lit up, the front-
passenger front air bag may deploy in an
accident. The child could be struck by the
air bag. This poses an increased risk of
injury or even fatal injury.
Make sure that the front-passenger front
air bag has been disabled. The PASSENGER
AIR BAG OFF indicator lamp must be lit.
If the PASSENGER AIR BAG OFF indicator lamp
remains off and/or the PASSENGER AIR BAG ON
indicator lamp is lit, do not fit a rearward-
facing child restraint system to the front-
passenger seat. For more information, see
Occupant safety37
>> Safety.

Rthe deformation characteristics of the
vehicle
Rthe 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.
Nor do they provide an indication of air bag
deployment.
The vehicle can be deformed considerably,
without an air bag being deployed. This is the
case if only parts which are relatively easily deformed are affected and the rate of decel-
eration is not high. Conversely, air bags may
be deployed even though the vehicle suffers
only minor deformation. This is the case if,
for example, very rigid vehicle parts such as longitudinal body members are hit, and suf-
ficient deceleration occurs as a result.
If the control unit of the restraint system
detects a side impact or a vehicle rollover,
the relevant components of the restraint sys-
tem are activated separately depending on
the anticipated type of accident.
RThorax/pelvis air bag on the side of
impact, independently of the Emergency
Tensioning Device and the use of the seat
belt
The thorax/pelvis air bag on the front-
passenger side deploys under the following
conditions:
-the OCS system detects that the front-
passenger seat is occupied or
-the belt tongue is engaged in the belt
buckle of the front-passenger seat
RWindow curtain air bag on the side of
impact, independently of the use of the seat
belt and independently of whether the
front-passenger seat is occupied
RWindow curtain air bags on the driver's andfront-passenger side in certain situations
when the vehicle rolls over, if the system
determines that deployment can offer
additional protection to that provided by
the seat belt
REmergency Tensioning Devices, if the sys-
tem determines that deployment can offer
additional protection in this situation
iNot all air bags are deployed in an acci-
dent. The differ ent air bag systems work
independently of each other. How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or
acceleration and the apparent type of acci-
dent:
RFrontal collision
RSide impact
RRollover
Children in the vehicle
Important safety notes
If a child younger than 12 years 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 Mercedes-Benz vehi-
cles. 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
Rbe sure to observe the instructions and
safety notes in "Occupant classification
system (OCS)" (
