To operate the front power seat adjustment switches, 
turn the electronic key in starter switch to position 1 
or 2 (with respective front door open, the power seats 
can also be operated with the electronic key removed or 
in starter switch position 0).
Note:
If the passenger side seat backrest is set to a full upright 
position and the passenger seat is moved fully forward, 
the cup holder next to the armrest must be removed 
(page 166) and the cup holder in the passenger footwell 
(page 167) must be folded closed.
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  unl ocked vehic l e. Uns upervi s ed us e of  vehi cl e 
equipment may cause serious personal injury.

Important!
Prior to operating the vehicle, the driver should check 
and adjust if necessary the seat height, seat position 
fore and aft, and backrest angle to insure adequate 
control, reach and comfort. The head restraint should 
also be adjusted for proper height. See also airbag 
section for proper seat positioning.
In addition, also adjust the steering wheel to ensure 
ad eq uate  con tr ol, r each,  operation  and  com fort. B ot h 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.

• Sit properly belted in an upright position with 
your back against the backrest.• Adjust the driver’s seat as far as possible 
rearward, still permitting proper operation of 
vehicle controls. The distance from the center 
of the driver’s breastbone to the center of the 
airbag cover on the steering wheel must be at 
least ten inches (25 cm) or more. You should be 
able to accomplish this by a combination of 
adjustments to the seat and steering wheel. If 
you have any problems, please see your 
authorized Mercedes-Benz Light Truck Center.• Do not lean with your head or chest close to the 
steering wheel or dashboard.• Keep hands on the outside of steering wheel 
rim. Placing hands and arms inside the rim 
can increase the risk and potential severity of 
hand / arm injury when the driver front airbag 
inflates.• Adjust the front passenger seat as far as 
possible rearward from the dashboard when 
the seat is occupied.
• Always sit upright, properly use the seat belts 
and appropriate size infant or child restraint 
system.• 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.
• Accident research shows that the safest place 
for children in an automobile is in the rear 
seat. Should you choose to place a child 12 
years old or under in the front passenger seat 
of your vehicle, you must properly use a 
BabySmart
TM chi ld  restrai nt  whi ch w il l turn of f 
the passenger side front airbag. 
Failure to follow these instructions can result in 
severe or fatal injuries to you or other occupants.
