The slide switches are located in each door.
We recommend to adjust the power seat in the following 
order:
1Seat, up/down 
Press the switch (up/down direction) until 
comfortable seating position with still sufficient 
headroom is reached.
2Seat, fore/aft 
Press the switch (fore/aft direction) until a 
comfortable seating position is reached that still 
allows you to reach the accelerator/brake pedal safely. The position should be as far rearward as 
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.
3Seat cushion tilt 
Press the switch in the direction of the arrow until 
your legs are lightly supported.
4Backrest tilt 
Press the switch in the direction of the arrow until 
your arms are slightly angled when holding the 
steering wheel.

automatically adjusted based on seat (fore/aft) 
position to support the back of the head 
approxima tely at ear l evel . Plea se check th e position 
of the head restraint to assure that it supports the 
back of the head approximately at ear level. The 
head restraint angle can also be adjusted manually.

inside rear view mirror, see page 79;
exterior rear view mirrors, see page 80.Caution!

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.
