possible, consistent with ability to properly operate
controls.Note:
Do not move the front passenger seat completely
forward if objects are stored in the parcel net in the
front passenger-side footwell. Items in the net may
be damaged.

Press the switch (up / down direction) until
comfortable seating position with still sufficient
headroom is reached.

6Head restraint
The height of the head restraint is adjusted
automatically with the seat so that the back of the
head is supported approximately at ear level. Adjust
the head restraint using the switch if the preset
position does not support the back of your head
approximately at ear level.
For steering wheel adjustment, see page 102;
rear view mirror, see page 103;
exterior rear view mirrors, see page 104.Adjust the head restraint angle (1) by hand. Push or pull
the head restraint in direction of arrow.
Storing seat positions
The head restraint, steering wheel and rear view mirror
position are stored together with the seat position.
See page 108 for notes on the memory function. For
recalling a stored seat / head restraint / steering wheel /
and rear view mirror position see page 109.

cluster displayPractical hints Car care Index 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 91 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.
