Seats, Front

Warning !
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 back reclined. Sitting in an excessively
reclined position 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
abdomen or neck. That could cause serious or even fatal injuries. The seat backrest and seat belt provide
the best restraint when the wearer is in an upright position and the belt is property positioned on the body.
Never place hands under seat or near any moving parts while a seat is being adjusted


A - Seat, fore/aft
B - Seat, up/down
C - Seat tilt
D - Backrest tilt
E - Head restraint


Adjust head restraint to support the back of the head approximately at ear level.
The head restraint angle can also be adjusted manually.
Note:
Your car is equipped with power head restraints , do not try to raise or lower them manually.


Power Seat
The slide switches are located in each front door. Turn elec tronic key in steering lock to position 1 or 2 (with a front
door open, the power seats can also be operated with the electronic key removed or in steering lock position 0).

Warning !
When leaving the vehicle always remove the electronic key from the steering lock. The power seats can also
be operated with the driver's or passenger door open. Do not leave children unattended in the vehicle or with
access to an unlocked vehicle. Unsupervised use of vehicle equipment may cause serious personal injury.

Caution !
Do not remove head restraints except when mounting seat co vers. For removal refer to Head Restraints, Front, see
Index. Whenever restraints have been removed be sure to reinstall them
before driving.

Important !
Prior to operating the vehicle, the driv er should adjust the seat height for proper vision as well as fore/aft placement
and seat back angle to insure adequate control, reach, operation, and comfort. The head restraint should also be
adjusted for proper height. See also airbag section for prope r seat positioning. 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 213.1. All seat, head restraint, and rear view mirror adjustments as well as
fastening of seat belts should be done before the vehicle is put into motion.

Warning !
Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized
BabySmart™ compatible child seat, which operates with the BabySmart™ system installed in the vehicle to
deactivate the passenger side 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. The back seat is the safest place
for children. 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 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.
