Seats
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.
Warning!
G
Do not adjust the driver’s 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
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
fatal injuries. The seat backrest 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 46).
Never place hands under the seat or near
any moving parts while a seat is being ad-
justed.
Warning!
G
When leaving the vehicle, always remove the
SmartKey or the SmartKey with
KEYLESS-GO* from the starter switch, take
it with you, and lock the vehicle.
Even with the SmartKey or the SmartKey
with KEYLESS-GO* removed from the start-
er switch or the SmartKey with
KEYLESS-GO* removed from the vehicle,
the power seats can be operated when the
respective 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.

Warning!
G
Children 12 years old and under must never
ride in this vehicle, except in a
Mercedes-Benz authorized BabySmart
TM
compatible child seat, which operates with
the BabySmart
TM system installed in the ve-
hicle to deactivate the passenger front air-
bag when it is properly installed. Otherwise
they will be struck by the airbag when it in-
flates in a crash. If this happens, serious or
fatal injury will result.
Infants and small children must be seated in
an appropriate infant or child restraint sys-
tem, which is properly secured with the ve-
hicle’s seat belt, fully in accordance with the
child seat manufacturer’s instructions.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.
iThe memory function (
page 121) lets
you store the settings for the seat posi-
tion together with the settings for the
steering wheel and the exterior rear
view mirrors.
!When moving the seats, make sure
there are no items in the footwell or be-
hind the seats. Otherwise you could
damage the seats.

66 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 airbag cover on
the steering wheel must be at least
10 inches (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 airbag 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 airbag in-
flates. This could result in serious inju-
ries or death should the airbag be
triggered. Always sit nearly upright,
properly use the seat belts and appropri-
ate size infant or child restraint system.
Children 12 years old and under must
never ride in this vehicle, except in a
Mercedes-Benz authorized
BabySmart
TM compatible child seat,
which operates with the BabySmart
TM
system installed in the vehicle to deacti-
vate the passenger front airbag when it
is properly installed. Otherwise they will
be struck by the airbag 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
Operator’s Manual.
67 Safety and Security
Occupant safety
Warning!
G
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
TM child restraint which will turn
off the passenger front airbag (
page 76).
BabySmart
TM will not, however, turn off any
side impact airbag.
It should be noted, however, that there is a
possibility for a head-thorax airbag related
injury if occupants, especially children, are
not properly seated or restrained when next
to a head-thorax airbag which needs to de-
ploy 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
head-thorax airbag inflates. This could
result in serious injuries or death should
the head-thorax airbag 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 side head-thorax airbag deactivated,
then deactivation can be accomplished
upon your written election 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 (1-800-367-6372)
for details.
72 Safety and SecurityOccupant safetyAlways wear your seat belt. All vehicle
occupants 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 information on fastening seat belts,
see “Fastening the seat belts” (
page 46).
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 76).
Warning!
G
Always fasten your seat belt before driving
off. Always make sure your passengers are
properly restrained, even 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 passenger should al-
ways 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. Airbags can only protect as
they are designed if the occupants are prop-
erly wearing their seat belts (
page 65).
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. This 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.
Keep door storage compartments closed
while vehicle is in motion. Failure to do so
may cause the seat belt to catch at the rear
and prevent proper positioning of the seat
belt.
