Brief overview of the most important points
Basic information
Make sure that the following prerequisites in par-

= Sit correctly (  page 41).
= Fasten the seat belt correctly (  page 42).
- Function of the seat belt warning lamp

Note that negligence when adjusting your sittingposture and fastening the seat belt may have seri-
ous consequences. Be diligent and make sure that all vehicle occupants are sitting correctly and
have fastened their seat belts properly before
starting every journey.
Information on the correct seat position
The seat position must be correct in order for the
components of the restraint system to provide the intended level of protection.
The seat position in"Ouences both the protection
provided by the seat belt and the additional pro- tection provided by the air bag.
The correct seat position with an almost upright
posture and a correctly fastened seat belt also
reduce the risk posed by the air bag when it is
deployed.
When choosing the seat, take note of the available space. When you are sitting with the right posture
in a nearly upright position, your head should not
touch the roof.
&WARNING Risk of injury or death due to
an incorrect seat position
If you deviate from the correct seat position,
the air bag cannot provide its intended protec-
tive function.
Each vehicle occupant must make sure of the
following.
Put the seat in the correct position.Fasten seat belts correctly. Pregnant
women must take particular care to
ensure that the lap belt never lies across
the abdomen.Observe the following information.
In order for the restraint system to provide the intended level of protection, observe the following information:
= Before starting your journey, adjust your seat
correctly (  page 95).
When doing so, make sure you are able to fas-
ten your seat belt correctly. The shoulder belt
strap must be routed forward from the seat belt outlet over the center of your shoulder.
= Keep your distance from the air bags, espe-
cially the front air bags. Set the driver\bs seatand front passenger seat as far back as possi-
ble while making sure the seat belt is fastened
correctly.
= If persons are sitting on the rear seats, vehicle
occupants should maintain a su"Pcient dis-
tance to the parts of the vehicle interior in front of them.
= Make sure there are no people, animals or
objects between the vehicle occupants and an air bag.
= If you are the driver, observe the following
information on the correct position of the driv-
er\bs seat (  page 95).
Hold the steering wheel only by the steering wheel rim. This allows the driver\bs air bag to
fully deploy.
= Assume a nearly upright position, with your
buttocks as far back as possible in the gap between the seat cushion and seat backrest.
This ensures that your back lies as "Oat and
"Nrmly as possible against the seat backrest.Occupant safety !

=While driving, do not lean forward and do not
lean against the door or side window. You may otherwise be in the deployment area of the air
bags.
= Sit with your feet resting on the "Ooor, if possi-
ble. Your thighs are slightly supported by the seat cushion
Do not put your feet up on the cockpit, for
example. Your feet may otherwise be in the
deployment area of the air bag.
= Fasten the seat belt correctly.
Notes on wearing the seat belt correctly
Always fasten your seat belt correctly before
starting a journey. A seat belt can provide the
best level of protection only if it is worn correctly.
&WARNING Risk of injury or death due to
incorrectly fastened seat belt
If the seat belt is not worn correctly, it cannot
perform its intended protective function.
In addition, an incorrectly fastened seat belt
can also cause injuries, for example, in the event of an accident or when braking or
changing direction suddenly.Always ensure that all vehicle occupants
have their seat belts fastened correctly
and are sitting properly.&WARNING Risk of injury or death when
additional restraint systems are not used
for persons with a smaller stature
Persons under 5 "s (1.50 m ) tall cannot wear
the seat belt correctly without a suitable addi-
tional restraint system.
Always secure persons under 5 "s
(1.50 m) tall in a suitable restraint sys-
tem.
Each vehicle occupant must observe the following
notes in particular:
= The seat belt must not be twisted:
=The shoulder belt strap must be routed
forward from the seat belt outlet over the cen- ter of your shoulder.
= The shoulder belt strap should neither touch
your neck nor be routed under your arm or
behind your back.
= The lap belt must be routed as low down
across the hips as possible.
In addition, push the lap belt down as far as
possible across your hips and pull tight with the shoulder belt strap. Never route the lap
belt across your abdomen.
Pregnant women must also take particular
care with this.
= The shoulder belt strap and lap belt must "Nt
snugly against the body a"ser being tightened.
= Avoid wearing bulky clothing, e.g. a winter
coat.
= Never route the seat belt across sharp, poin-
ted, abrasive or fragile objects.
= Only one person should use each seat belt at
any one time.42Occupant safety !

=Never secure objects with a seat belt if the
seat belt is also being used by one of the vehi-
cle\bs occupants.
Also ensure that no objects, e.g. a cushion,
are ever placed between a person and the seat.
Fastening and adjusting seat belts
If the seat belt is pulled quickly or sharply, the
seat belt retractor locks. The seat belt strap can-
not be pulled out any further.
Always engage seat belt tongue 1 of the seat
belt into seat belt buckle 2 of the corre-
sponding seat.To adjust the seat belt height: press button 3
on the seat belt outlet and slide the seat belt outlet to the desired position.To engage the seat belt outlet: release button
3 and ensure that the seat belt outlet
engages.*NOTE Deployment of components of the
restraint system when the front passenger
seat is unoccupied and a seat belt is
buckled
When the front passenger seat is unoccupied
and the seat belt tongue of the seat belt is
engaged in the seat belt buckle, components
of the restraint system may deploy unnecessa-
rily on the front passenger side, e.g. the Emer-
gency Tensioning Device.
Only buckle the seat belts as intended.\bObserve the information on child seat safety
feature of the seat belt (  page 65).
Function of the restraint system warning lamp
When the vehicle is switched on, a self-test is per-
formed, during which the restraint system warning lamp u lights up. It goes out no later than a
few seconds a"ser the vehicle is started. The com-
ponents of the restraint system are then func-
tional.
Occupant safety !

A malfunction has occurred in the restraint sys-tem if:
= the restraint system warning lamp u does
not light up when the vehicle is switched on
= the restraint system warning lamp u lights
up continuously or repeatedly during a journey
If components of the restraint system have been
deployed, the restraint system warning lamp u
lights up continuously.&WARNING Risk of injury due to malfunc-
tions in the restraint system
Components in the restraint system may be activated unintentionally or not deploy as plan-
ned in an accident.
Have the restraint system checked and
repaired immediately at a quali"Ned spe-
cialist workshop.
Mercedes-Benz recommends that you have the
vehicle towed to a quali"Ned specialist workshop.

and during a journey, that the status of the front
passenger air bag is correct for the current situa-
tion.&WARNING Risk of potentially fatal injuries
due to objects trapped under the front
passenger seat
Objects trapped under the front passenger
seat may interfere with the function of the
automatic front passenger air bag shuto"M or
damage the system.
Do not stow any objects under the front

pied, ensure that no objects have
become trapped beneath the front
passenger seat.
Self-test: when the vehicle is switched on, both
the PASSENGER AIR BAG ON and OFF indicator
lamps light up simultaneously for several seconds.
A"ser the self-test, you can determine the status of
the front passenger air bag as follows:
= Front passenger air bag disabled: PASSENGER
AIR BAG OFF lights up continuously.
Occupant safety !

The front passenger air bag will not be
deployed in the event of an accident. If
PASSENGER AIR BAG OFF is lit, no one may
use the front passenger seat.
If a rearward-facing child restraint system is installed on the front passenger seat,
PASSENGER AIR BAG OFF must be lit continu-
ously.
