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 67 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 will 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 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.

lap-shoulder belts except the driver’s seat belt have
special seat belt retractors for secure fastening of child
restraints.

retract. During the seat belt retraction a ratcheting
sound can be heard to indicate that the special seat belt
retractor is activated. The belt is now locked.
To deactivate, release seat belt buckle and let seat belt
retract completely. The seat belt can again be used in
the usual manner.
