• 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.
• 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. Always sit upright, properly use the 
seatbelts 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.
Failure to follow these instructions can result in 
severe or fatal injuries to you or other occupants.

Wa r n i n g !
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 child 
restraint which will turn off the passenger side 
front airbag. BabySmart
TM will not, however, turn 
off the vehicle’s side impact airbag. 
It should be noted that with respect to both front 
and rear side impact airbags there is a possibility 
for a side airbag related injury if occupants, 
especially children, are not properly seated or 
restrained when next to a side airbag which needs 
to deploy rapidly in a side impact in order to do its 
job.
To help avoid the possibility of injury, please follow 
these guidelines: (1) occupants, especially 
children, should never place their bodies or lean 
their heads in the area of the door where the side 
airbag inflates. This could result in serious 
injuries or death should the side airbag be 
activated; (2) always sit upright, properly use the 
seat belts and use an appropriately sized infant or 
child restraint system for all children 12 years old 
or under; and (3) always wear seat belts properly.If you believe that, even with the use of these 
guidelines, it would be safer for your rear seat 
occupants to have both rear door mounted side 
airbags deactivated, then deactivation can be 
accomplished upon your written election to do so at 
your authorized Mercedes-Benz Center at an 
additional cost. Please contact your local 
authorized Mercedes-Benz Center or call our Client 
Assistance Center at 1-800-FOR-MERCedes 
(1-800-367-6372) for details.

To  a ctiva te:
Press button (1). The green indicator lamp in the rear 
view mirror lights up.To deactivate:
Press button (1) again. The indicator lamp in the rear 
view mirror goes out. The mirror brightness does not 
respond to changes in light sensitivity.

With gear selector lever in position “R”, or with the 
interior lamps (except cargo compartment lamp) 
switched on, the mirror brightness does not respond to 
changes in light sensitivity.
The automatic antiglare function does not react, if 
incoming light is not aimed directly at sensors in the 
mirror.
Wa r n i n g !
In the case of an accident liquid electrolyte may 
escape the mirror housing when the mirror glass 
breaks.Electrolyte has an irritating effect. Do not allow the 
liquid come into contact with eyes, skin, clothing, 
or respiratory system. In cases it does, immediately 
flush affected area with water, and seek medical 
help if necessary.

Vehicles with automatic antiglare function:
With the key in steering lock position 2, the driver’s 
side mirror reflection brightness responds to changes in 
light sensitivity.
With gear selector lever in position “R”, or with the 
interior lamps (except cargo compartment lamp) 
switched on, the driver’s side mirror brightness does 
not respond to changes in light sensitivity.Important!
Electrolyte drops coming into contact with the vehicle 
paint finish can only be completely removed while in 
their liquid state, by applying plenty of water.
Notes:
The exterior mirrors have electrically heated glass. The 
heater switches on automatically, depending on outside 
temperature.
If an exterior mirror housing is forcibly pivoted from its 
normal position, it must be repositioned by applying 
firm pressure until it snaps into place.
