Front seat adjustment 
To operate the front power seat adjustment switches, 
turn the electronic key in starter switch to position 1 
or 2 (with respective door open, the power seats can 
also be operated with the electronic key removed or in 
starter switch position 0).
Wa r n i n g !
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 fatal injuries. The seat back 
and seat belts provide the best restraint when the 
wearer is in an upright position and belts are 
properly positioned on the body.Never place hands under seat or near any moving 
parts while a seat is being adjusted.
When leaving the vehicle always remove the 
electronic key from the starter switch, and lock 
your vehicle. The power seats can also be operated with the 
driver’s or front 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.

automatically with the seat so that the back of the 
head is supported approximately at ear level. Adjust 
the head restraint using the switch to support the 
back of your head approximately at ear level.

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 72 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 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.
