Seats
The seats can be adjusted either manually
or electrically, depending on the vehicle’s
equipment.
For more information on seats, see “Seats”
(page 99).Warning!
G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before
the vehicle is put into motion.iThe memory function* (
page 103)
lets you store the setting for power
seats*, steering wheel adjustment
(electrical)*, and exterior rear view mir-
rors.
Warning!
G
Do not adjust the driver seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
back in an excessively reclined position as
this can be dangerous. You could slide un-
der 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
fatal injuries. The seat back and seat belts
provide the best restraint when the wearer
is in a nearly upright position and belts are
properly positioned on the body. Your seat
must be adjusted so that you can correctly
fasten your seat belt (
page 44).
Never place hands under the seat or near
moving parts while the seat is being
adjusted.
Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle.
Even with the SmartKey removed from the
starter switch, the power seats* can be op-
erated when the respective door is open.
Therefore, do not leave children unattended
in the vehicle, or with access to an unlocked
vehicle. Unsupervised use of vehicle equip-
ment may cause an accident and/or serious
personal injury.

when it inflates in a crash. If this happens,
serious or fatal injury will result.
Infants and small children must be seated in
an appropriate BabySmart
TM compatible in-
fant or child restraint system, which is prop-
erly secured with the vehicle’s seat belt,
fully in accordance with the child seat
manufacturer’s instructions.

Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the head re-
straint supports the back of the head at eye
level. This will reduce the potential for injury
to the head and neck in the event of an ac-
cident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.
iAdjust the head restraint in such a way
that it is as close to the head as
possible.
Warning!
G
Do not adjust the steering wheel while driv-
ing. Adjusting the steering wheel while driv-
ing, or driving without the steering wheel
adjustment feature locked could cause the
driver to lose control of the vehicle.
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle.
Even with the SmartKey removed from the
starter switch, the electrical steering wheel
adjustment feature* can be operated when
the driver’s door is open. Therefore, do not
leave children unattended in the vehicle, or
with access to an unlocked vehicle. Unsu-
pervised use of vehicle equipment may
cause an accident and/or serious personal
injury.

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
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.

Read and observe the additional warning no-
tices printed in the “Safety and Security”
section (
page 66) and (
page 69).
47 Getting started
Driving
Never use a seat belt for more than one
person at a time.
Do not fasten a seat belt around a per-
son and another object at the same
time.
When using a seat belt to secure infant
or toddler restraints or children in
booster seats, always follow the child
seat manufacturer’s instructions.
Check your seat belt during travel to
make sure it is properly positioned.
Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.
Starting the engine
Warning!
G
Do not pass belts over sharp edges. They
could tear.
Do not allow the belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the 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.
Damaged seat belts or belts that were highly
stressed in an accident must be replaced.
Contact an authorized Mercedes-Benz
Center.
Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one win-
dow fully open.

64 Safety and SecurityOccupant safety
Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion 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
ten inches (25 cm) or more. You should
be able to accomplish this by a combina-
tion of adjustments to the seat and the
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 the steer-
ing wheel rim. Placing hands and arms
inside the rim can increase the risk and
potential severity of hand/arm injury
when driver front air bag inflates.
Adjust the passenger seat as far as pos-
sible 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 head-thorax air bag in-
flates. This could result in serious inju-
ries or death should the air bag be
triggered. Always sit nearly upright,
properly use the seat belts and appropri-
ately sized infant or child restraint sys-
tem.
Children 12 years old and under must
never ride in this vehicle, 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-

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
Operator’s Manual.
65 Safety and Security
Occupant safety
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 passenger seat
of your vehicle, you must properly use a
BabySmart
TM1
child restraint which will turn
off the passenger front air bag.
BabySmart
TM will not, however, turn off any
head-thorax air bag.
It should be noted, however, that there is a
possibility of a head-thorax air bag related
injury if occupants, especially children, are
not properly seated or restrained when next
to a head-thorax air bag which needs to de-
ploy rapidly in a side impact in order to do its
job.
1BabySmart
TM is a trademark of Siemens
Automotive Corp.
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
head-thorax air bag inflates. This could
result in serious injuries or death should
the head-thorax 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
passenger seat occupants to have the pas-
senger head-thorax air bag deactivated,
then deactivation can be accomplished
upon your written request to do so at an au-
thorized Mercedes-Benz Center at an addi-
tional cost.
Please contact your local authorized
Mercedes-Benz Center or call our Customer
Assistance Center at 1-800-FOR-MERCedes
