• 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 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. 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 Baby Smart
TM compatible
child seat, which operates with the
BabySmart
TM system installed in the vehicle to
deactivate the passenger 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 injuries to you or other occupants.

Safety guidelines for the seat belt, emergency
tensioning retractor and airbag
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.Wa r n i n g !
• Damaged seat belts or belts that were highly
stressed in an accident must be replaced and
their anchoring points must also be checked.
Use only belts installed or supplied by an
authorized Mercedes-Benz Center.• Do not pass belts over sharp edges.• Do not make any modification that could
change the effectiveness of the belts.

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
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.
Infants and small children should never share a
seat belt with another occupant. During an
accident, they could be crushed between the
occupant and seat belt.Children too big for child restraint systems must
ride in back seats using regular seat belts. Position
shoulder belt across chest and shoulder, not face or
neck. A booster seat may be necessary to achieve
proper belt positioning for children from 41 lbs. to
the point where a lap / shoulder belt fits properly
without one.When the child restraint is not in use, remove it
from the vehicle or secure it with the seat belt to
prevent the child restraint from becoming a
projectile in the event of an accident.

Installation of infant and child restraint systems
This vehicle is provided with tether anchorages for a top
tether strap at each of the rear seating positions.
Prior to installing a tether strap, remove cover (1) from
anchorage ring (2) and store in a convenient place (e.g.
glove box).To secure a tether strap to the anchorage, securely
fasten the hook (3), which is part of the tether strap, to
the anchorage ring (2). For safety, please make sure that
the hook has attached to the ring beyond the safety
catch, as illustrated.
After removing the tether strap, reinstall the cover (1).

Manually adjust the mirror.
Use your inside mirror to determine the size and
distance of objects seen in the passenger-side convex
mirror.
Antiglare night position
With the electronic key in steering lock position 2, the
mirror reflection brightness responds to changes in
light sensitivity.
With gear selector lever in position “R”, or with the
interior lamp switched on, the mirror brightness does
not respond to changes in light sensitivity.Note:
The automatic antiglare function does not react, if
incoming light is not aimed directly at sensors in the
mirror.

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.

Note:
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.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.
Storing mirror positions in memory
The exterior rear view mirror positions are stored in
