tentionally or fail to be deployed when
required. There is an increased risk of injury,
possibly even fatal.
Never modify safety belts, seat belt tension-
ers, seat belt anchorages and inertia reels.
Ensure that seat belts are not damaged or
worn and are clean. After an accident, have
the seat belts checked immediately at a quali- fied specialist workshop.
Mercedes-Benz recommends that you only use
seat belts which have been approved specifi-
cally for your vehicle by Mercedes-Benz. Other-
wise, your vehicle's general operating permit
could be invalidated.
Correct seat belt use Pay attention to the safety notes about the seat
belt (Y page 38).
All vehicle occupants must fasten their seat
belts correctly before you start driving. You
must also make sure that all vehicle occupants
have fastened their seat belts correctly during
the journey.
When fastening your seat belt, always make
sure that:
R the seat belt tongue is inserted into the belt
buckle that belongs to the seat.
R the seat belt is tightened across your body.
Avoid wearing bulky clothing, e.g. a winter
coat.
R the seat belt is not twisted.
Only then can the forces which occur be dis-
tributed over the area of the belt.
R the shoulder section of the belt is routed
across the centre of your shoulder.
The shoulder section of the belt must not
come into contact with your neck or be routed
under your arm.
R The lap belt must be taut and as low as pos-
sible over your lap.
The lap belt must always be routed across
your hip joints and not across your abdomen.
Pregnant women must take particular care
with this. If necessary, push the lap belt down to your hip joint and pull it tight using the
shoulder section of the belt.
R The seat belt is not routed over sharp, pointed
or fragile objects. If such objects are located on or in your cloth-
ing, e.g. pens, keys, spectacles, etc. stow
these in a suitable location.
R Only one person should use each seat belt at
any one time.
Babies and children must never travel sitting
on the lap of another vehicle occupant. In the
event of an accident, they could be crushed
between the vehicle occupant and seat belt.
R Do not secure any objects with a seat belt if
the seat belt is being used by one of the vehi- cle's occupants.
Also ensure that no objects are placed
between a person and the seat. e.g. a cush-
ion.
Seat belts are solely intended to secure and
restrain persons. To secure objects, luggage or
loads, always observe the "Loading guidelines"
(Y page 265).
Fastening a seat belt Observe the safety notes on the seat belt
(Y
page 38) and the information on the correct
use of the seat belt (Y page 39). G
WARNING
If the seat-belt extender extends during the
journey, the seat belt is not sitting correctly
across your body. The seat belt then cannot
perform its intended protective function.
There is an increased risk of injury, possibly
even fatal.
During a journey, make sure that the seat-belt extender is retracted. The seat-belt extender for the driver and front
passenger helps you fasten your seat belt. Seat- belt extender =is extended when the respec- Occupant safety

In order to attach the child restraint system
securely in the vehicle, the seat belts in the rear
are equipped with a child seat lock. You can find
further information under "Child seat lock"
(Y page 48).
Automatic comfort-fit feature The front seat belts have an automatic comfort-
fit feature. The automatic comfort-fit feature
reduces the retraction force of the seat belts.
The seat belts are thus routed more comfortably for the driver and front passenger.
Releasing the seat belts !
Make sure that the seat belt is fully rolled up.
Otherwise, the seat belt or belt tongue will be
trapped in the door or in the seat mechanism.
This could damage the door, the door trim
panel and the seat belt. Damaged seat belts
can no longer fulfil their protective function
and must be replaced. Visit a qualified spe-
cialist workshop.
X Press release button in belt buckle, hold belt
tongue firmly and guide the seat belt back.
Seat belt adjustment The seat-belt adjustment is an integral part of
the PRE-SAFE
®
convenience function. This func-
tion adjusts the driver's and front-passenger
seat belt to the upper body of the occupants.
The belt strap is tightened slightly when:
R with a retracted seat-belt extender, the seat
belt tongue is engaged in the belt buckle and
R the ignition is switched on
The seat-belt adjustment will apply a certain
tightening force if any slack is detected between
the vehicle occupant and the seat belt. Do not 40

WARNING
If the seat belt is released while driving, the
child restraint system will no longer be
secured properly. The child seat lock is disa-
bled and the inertia real draws in a portion of
the seat belt. The seat belt cannot be imme-
diately refastened. There is an increased risk
of injury, possibly even fatal.
Stop the vehicle immediately, paying atten-
tion to road and traffic conditions. Reactivate the child seat lock and secure the child
restraint system properly.
The rear seat belts are equipped with a child
seat lock. When enabled, the child seat lock
function ensures that the seat belt does not
slacken once the child restraint system is
secured.

wards from the retracted seat-belt extender.
If necessary, adjust the front-passenger seat
accordingly. Always observe the information
about suitable positioning of the child
restraint system in this Owner's Manual as
well as the child restraint system manufac-
turer's installation instructions.
i Ensure that your vehicle is equipped with
automatic child seat recognition for the front-
passenger seat (Y page 52). If this is not the
case, always install a child restraint system on a suitable rear seat (Y page 55).PASSENGER AIR BAG OFF indicator lamp
:
shows you whether the front-passenger front
airbag is disabled.
X Turn the key to position 1or 2in the ignition
lock or, on vehicles with KEYLESS-GO, press
the Start/Stop button once or twice.
The system carries out a self-diagnosis.
The PASSENGER AIR BAG OFF indicator lamp
must light up for approximately six seconds.
If, after the system self-test, the
PASSENGER AIR BAG OFF indicator lamp:
R lights up , the front-passenger front airbag is
disabled. It will then not be deployed in the
event of an accident.
R is not lit , the sensor system did not detect a
child restraint system with transponder for
automatic child seat recognition. If, in the
case of an accident, all deployment criteria
are met, the front-passenger front airbag is
deployed. G
WARNING
Electronic devices on the front-passenger
seat can affect the function of the automatic
child seat recognition, for example:
R laptop
R mobile phone
R transponder cards such as ski passes or
access passes
The front-passenger front airbag could deploy unintentionally or not function as intended
during an accident. This poses an increased
risk of injury or even fatal injury.
Do not place any of the devices mentioned
above or similar devices on the front-
passenger seat. Be aware of the status of the front-passenger front airbag both before and
during the journey. 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 seats. For this reason, Mercedes-
Benz strongly advises that you fit a child
restraint system on a rear seat.
Vehicles with automatic child seat recognition
on the co-driver's seat: if it is absolutely neces-
sary to fit a child restraint system to the co-driv- er's seat, always observe the notes on "Auto-
matic child seat recognition on the co-driver's
seat" (Y page 52).
You can thus avoid the risks that could arise as
a result of:
R a child restraint system that is not detected
by the automatic child seat recognition's sen-
sor system
R the unintentional disabling of the co-driver's
front airbag
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board. 52
Children in the vehicleSafety

Please observe the warning notice on the co-
driver's sun visor, see the illustration. G
WARNING
If you secure a child in a child restraint system on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is
off, the front-passenger front airbag can
deploy in the event of an accident. The child
could be struck by the airbag. 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.
NEVER use a rearward-facing child restraint on a seat protected by an ACTIVE AIRBAG in front of
it, DEATH or SERIOUS INJURY to the CHILD can
occur.
Vehicles without automatic child seat
recognition on the co-driver's seat If the co-driver's seat of your vehicle is not
equipped with automatic child seat recognition,
this is indicated by a special sticker. The sticker is affixed to the side of the dashboard on the co- driver's side. The sticker is visible when you
open the co-driver's door.
The PASSENGER AIR BAG OFF indicator lamp
lights up briefly when the key is turned to posi-
tion
2in the ignition lock. It has no function,
however, and does not indicate that the co-driv-
er's seat is equipped with automatic child seat
recognition.
If you turn the key to position 2in the ignition
lock, the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps light
up briefly. They have no function, however, and do not indicate that the co-driver's seat is equip- ped with automatic child seat recognition.
Always fit the rearward-facing restraint system
to a suitable rear seat in this case (Y page 55).
Observe the following information under "Rear-
ward-facing child restraint system" and
"Forward-facing child restraint system" and on
suitable positioning of the child restraint system (Y page 55).
Rearward-facing child restraint system Warning symbol for a rearward-facing child
restraint system
If it is absolutely necessary to fit a rearward-
facing child restraint system to the co-driver's
seat, you must always make sure that the co-
driver's front airbag is deactivated. The co-driv-
er's front airbag is only disabled if the
PASSENGER AIRBAG OFF indicator lamp is lit
continuously (Y page 37).
