Adjust the driver’s seat as far as possi-
ble rearward, still permitting proper op-
eration of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the air bag cover
on the steering wheel must be at least
10 in (25 cm) or more. You should be
able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see an authorized
Mercedes-Benz Center.
Do not lean with your head or chest
close to the steering wheel or dash-
board.
Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver front air bag inflates.
Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.
Occupants, especially children, should
never lean their heads in the area of the
door where the side air bag inflates.
This could result in serious injuries or
death should the air bag be triggered.
Always sit nearly upright, properly use
the seat belts and appropriate size in-
fant or child restraint system.
Children 12 years old and under must
never ride in the front seat, except in a
Mercedes-Benz authorized
BabySmart
TM1
compatible child seat,
which operates with the BabySmart
TM
system installed in the vehicle to deacti-
vate the passenger front air bag when it
is properly installed. Otherwise they will
be struck by the air bag when it inflates
in a crash. If this happens, serious or fa-
tal injury will result.
Failure to follow these instructions can re-
sult in severe injuries to you or other occu-
pants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety in-
formation. Be sure to give the buyer this Op-
erator’s Manual.

Warning!
G
Accident research shows that the safest
place for children in an automobile is in the
rear seat. Should you choose to place a child
12 years old or under in the front passenger
seat of your vehicle, you must properly use
a BabySmart
TM child restraint which will
turn off the passenger front air bag.
BabySmart
TM will not, however, turn off any
side impact air bag.
It should be noted that with respect to both
front and rear side impact air bags there is a
possibility for a side air bag related injury if
occupants, especially children, are not prop-
erly seated or restrained when next to a side
air bag which needs to deploy rapidly in a
side impact in order to do its job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
side air bag inflates. This could result in
63 Safety and Security
Occupant safety
serious injuries or death should the side
air bag be activated.
(2) Always sit nearly upright, properly use
the seat belts and use an appropriately
sized infant or child restraint system for
all children 12 years old or under.
(3) Always wear seat belts properly.
If you believe that, even with the use of
these guidelines, it would be safer for your
rear seat occupants to have the rear mount-
ed side air bags deactivated, then deactiva-
tion can be accomplished upon your written
request to do so at your authorized
Mercedes-Benz Center at an additional cost.
Please contact your local authorized
Mercedes-Benz Center or call our Customer
Assistance Center at 1-800-FOR-MERCedes
(1-800-367-6372) for details.
iAir bags are designed to activate only
in certain frontal (front air bags) im-
pacts, side impacts (side impact and
head protection window curtain
air bags) which exceed preset thresh-
olds, and in certain rollovers (head pro-
tection window curtain air bags). Only
during these events will they provide
their supplemental protection.
The driver and passengers should al-
ways wear their seat belts. Otherwise it
is not possible for air bags to provide
their supplemental protection.
In case of other types of impacts and
impacts below air bag deployment
thresholds, air bags will not be activat-
ed. The driver and passengers will then
be protected to the extent possible by
a properly fastened seat belt. A proper-
ly fastened seat belt is also needed to
provide the best possible protection in
a rollover.
We caution you not to rely on the pres-
ence of the air bags in order to avoid
wearing your seat belt.
Your vehicle was originally equipped
with air bags that are designed to acti-
vate in certain impacts exceeding a
preset threshold to reduce the poten-
tial and severity of injury. It is important
for your safety and that of your passen-
gers that you replace deployed air bags
and repair any malfunctioning air bags
to make sure the vehicle will continue
to provide supplemental crash protec-
tion for occupants.
65 Safety and Security
Occupant safety
When you sell your vehicle we strongly
urge you to give notice to the subsequent
owner that it is equipped with an SRS by
alerting them to the applicable section in
the Operator’s Manual.
Front air bags
1Driver’s front air bag
2Passenger front air bagDriver’s and passenger front air bags are
deployed:
in the event of certain frontal impacts
if impact exceeds a preset deployment
threshold
independently of the side impact
air bags
The air bags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protect-
ed by the fastened seat belts.The passenger front air bag will only be de-
ployed if:
the front passenger seat is occupied
the 58 indicator lamp in the
lower part of the front center console is
not lit (
page 73)
the impact exceeds a preset deploy-
ment threshold!Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the front or side
impact air bag on the front passenger
side to deploy in a crash which exceeds
the system’s deployment threshold.

Seat belts
When the engine is started, the seat belt
telltale< illuminates to remind you and
your passengers to fasten your seat belts.
If the driver’s seat belt is not fastened be-
fore the engine is started, the seat belt
telltale< illuminates and a warning
chime sounds for approximately six sec-
onds when the engine is started.
Always wear your seat belt. All vehicle oc-
cupants always need to have their seat
belts fastened and wear them properly.
In addition, applicable motor vehicle safety
laws require you to wear seat belts. Even
where this is not the case, we strongly rec-
ommend that all vehicle occupants have
their seat belts fastened and wear them
properly.
For more information, see “Fastening the
seat belts” (
page 43).
iFor information on infants and children
traveling with you in the vehicle and re-
straint systems for infants and chil-
dren, see “Children in the vehicle”
(page 71).
Warning!
G
Always fasten your seat belt before driving
off. Always make sure your passengers are
properly restrained, even those sitting in the
rear and pregnant women.
Failure to wear and properly fasten and po-
sition your seat belt greatly increases your
risk of injuries and their likely severity in an
accident. You and your passengers should
always wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled. Without
your seat belt buckled, you are much more
likely to hit the interior of the vehicle or be
ejected from it. You can be seriously injured
or killed.
In the same crash, the possibility of injury or
death is lessened if you are properly wearing
your seat belt. Air bags can only protect as
they are designed if the occupants are prop-
erly wearing their seat belts.Warning!
G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this can be dangerous. You could slide
under the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen or neck. That could cause serious or
even fatal injuries. The seat backrest and
seat belt provide the best restraint when the
wearer is in a nearly upright position and the
belt is properly positioned on the body.
68 Safety and SecurityOccupant safetyWarning!
G
Never let more people ride in the vehicle
than there are seat belts available. Be sure
everyone riding in the vehicle is correctly re-
strained with a separate seat belt. Never use
a seat belt for more than one person at a
time.Warning!
G
Damaged seat belts or belts that were highly
stressed in an accident must be replaced
and their anchoring points must also be
checked.
Only use seat belts which have been ap-
proved by Mercedes-Benz.
Do not make any modifications to the seat
belts. This can lead to failure of the seat
belts.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Have all work carried out only by qualified
technicians. Contact an authorized
Mercedes-Benz Center.Warning!
G
USE SEAT BELTS PROPERLY
Seat belts can only work when used
properly. Never wear seat belts in any
other way than as described in this sec-
tion, as that could result in serious inju-
ries in case of an accident.
Each occupant should wear their seat
belt at all times, because seat belts help
reduce the likelihood of and potential
severity of injuries in accidents, includ-
ing rollovers. The integrated restraint
system includes SRS (driver’s air bag,
passenger front air bag, side impact
air bags, head protection window cur-
tain air bags for side windows), ETD
(seat belt emergency tensioning device),
and front seat knee bolsters. The sys-
tem is designed to enhance the protec-
tion offered to properly belted
occupants in certain frontal (front
air bags and ETD) and side (side impact,
window curtain air bags and ETD) im-
pacts which exceed preset deployment
thresholds and in certain rollovers (win-
dow curtain air bags and ETD).
Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. In a crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The
belt would also apply too much force to
the ribs or abdomen, which could se-
verely injure internal organs such as
your liver or spleen.
Never wear belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, keys, etc., as these
might cause injuries.
Position the lap belt as low as possible
on your hips and not across the abdo-
men. If the belt is positioned across your
abdomen, it could cause serious injuries
in a crash.

Children in the vehicle
If an infant or child is traveling with you in
the vehicle:
Secure the child using an infant or child
restraint appropriate for the age and
size of the child.
Make sure the infant or child is proper-
ly secured at all times while the vehicle
is in motion.
Infant and child restraint seats and infor-
mation on choosing an appropriate re-
straint system can be obtained from any
authorized Mercedes-Benz Center.
Infant and child restraint systems
Use only a BabySmart
TM1
compatible child
restraint for the front passenger seat in
this vehicle.
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.All lap-shoulder belts except the driver’s
seat belt have special seat belt retractors
for secure fastening of child restraints.
To fasten a child restraint, follow child re-
straint instructions for mounting. Then pull
the shoulder belt out completely and let it
retract. During seat belt retraction, a ratch-
eting sound can be heard to indicate that
the special seat belt retractor is activated.
The belt is now locked. Push down on child
restraint to take up any slack.
To deactivate, release seat belt buckle and
let seat belt retract completely. The seat
belt can again be used in the usual man-
ner.
