To operate the front power seat adjustment switches, 
turn the electronic key in starter switch to position 1 
or 2 (w ith a front door ope n, th e power seats ca n a lso 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, take the 
KEYLESS-GO-card (if so equipped) with you, 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.

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 92 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.

The automatic seat slide is provided with a safety 
feature.
The automatic process is interrupted, if the backrest of 
the sliding seat is pushed against an occupant or object. 
The seat will slide forward and stop.
Investigate and correct the cause of interruption.
Now use memory button (page 112) or power seat switch 
(page 68) to bring seat into desired position.
When folding the backrest forward from a reclined 
position, and then folding it back, the backrest stops in a 
more upright position for the safety of any rear-seat 
passenger. Adjust the backrest until your arms are 
slightly angled when holding the steering wheel, see 
page 68.
When leaving the vehicle always remove the 
electronic key from the starter switch, take the 
KEYLESS-GO-card (if so equipped) with you, and 
lock your vehicle.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.Never place hands under seat or near any moving 
parts during a seat adjustment procedure.

Seat belts and integrated restraint system
Your vehicle is equipped with seat belts for all seats, 
emergency tensioning retractors, dual front airbags, 
side impact airbags for driver, front and rear 
passengers, and head protective window curtain 
airbags. Their protective functions are designed to 
complement one another.
Seat belts
Important!
Laws in most states and all Canadian provinces require 
seat belt use. 
All states and provinces require use of child restraints 
that comply with U.S. Federal Motor Vehicle Safety 
Standard 213 and Canadian Motor Vehicle Safety 
Standard 213.
All child restraints systems are designed to be secured 
in vehicle seats by lap belts or the lap belt portion of a 
lap-shoulder belt.
For your safety and that of your passengers we strongly 
recommend their use.
