or 2 (with respective door open, the power seats can 
also be operated with the electronic key removed or in

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.

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.

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 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 driver front airbag 
inflates.• Adjust the front passenger seat as far as 
possible rearward from the dashboard when 
the seat is occupied.
• Occupants, especially children, should never 
lean their heads in the area of the door where 
the side airbag inflates. This could result in 
serious injuries or death should the airbag be 
triggered.• Children 12 years old and under must never 
ride in the front seat, except in a
