Important!
Prior to operating the vehicle, the driver should adjust
the seat height for proper vision as well as fore / aft
placement and backrest angle to insure adequate
control, reach, operation, and comfort. The head
restraint should also be adjusted for proper height. See
also airbag section on page 56 for proper seat
positioning.
In addition, also adjust the steering wheel to ensure
adequate control, reach, operation, and comfort.
Both the inside and outside rear view mirrors should be
adjusted for adequate rearward vision.
Fasten seat belts. Infants and small children should be
seated in a properly secured restraint system that
complies with U.S. Federal Motor Vehicle Safety
Standard 213 and Canadian Motor Vehicle Safety
Standard 213.
All seat, head restraint, steering wheel, and rear view
mirror adjustments as well as fastening of seat belts
should be done before the vehicle is put into motion.
Wa r n i n g !
Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmart
TM compatible child seat,
which operates with the BabySmart
TM system
installed in the vehicle to deactivate the passenger
side 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 fatal
injury can result.
According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in the back
seats and be seated in an appropriate infant or
child restraint system, which is properly secured
with the vehicle’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.

• Sit properly belted in an upright position with
your back against the backrest.• Adjust the driver’s seat as far as possible
rearward, still permitting proper operation of
vehicle controls. The distance from the center
of the driver’s breastbone to the center of the
airbag cover on the steering wheel must be at
least ten inches (25 cm) or more. You should be
able to accomplish this by a combination of
adjustments to the seat and steering wheel. If
you have any problems, please see your
authorized Mercedes-Benz Light Truck Center.• Do not lean with your head or chest close to the
steering wheel or dashboard.• Keep hands on the outside of steering wheel
rim. Placing hands and arms inside the rim
can increase the risk and potential severity of
hand / arm injury when the driver front airbag
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 airbag inflates. This could result in
serious injuries or death should the airbag be
triggered. Always sit upright, properly use the
seatbelts and appropriate size infant or child
restraint system.• Children 12 years old and under must never
ride in the front seat, except in a
Mercedes-Benz authorized BabySmart
TM
compatible child seat, which operates with the
BabySmart
TM system installed in the vehicle to
deactivate the passenger side 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 fatal injury
can result.
Failure to follow these instructions can result in
severe or fatal injuries to you or other occupants.
