forward if objects are stored in the parcel net in the
front passenger-side footwell. Items in the net may
be damaged.

6Head restraint
The height of the head restraint is adjusted
automatically with the seat so that the back of the
head is supported approximately at ear level. Adjust
the head restraint using the switch if the preset
position does not support the back of your head
approximately at ear level.
For steering wheel adjustment, see page 102;
rear view mirror, see page 103;
exterior rear view mirrors, see page 104.Adjust the head restraint angle (1) by hand. Push or pull
the head restraint in direction of arrow.
Storing seat positions
The head restraint, steering wheel and rear view mirror
position are stored together with the seat position.
See page 108 for notes on the memory function. For
recalling a stored seat / head restraint / steering wheel /
and rear view mirror position see page 109.

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 91 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.

Te ch n i c a l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Your vehicle was originally equipped with airbags
which are designed to activate in certain impacts
exceeding a preset threshold to reduce the potential
and severity of injury. It is important to your safety
and that of your passenger that you replace deployed
airbags and repair any malfunctioning airbags to
ensure the vehicle will continue to provide crash
protection for occupants.
Wa r n i n g !
To reduce the risk of injury when the front airbags
inflate, it is very important for the driver and front
passenger to always be in a properly seated
position and to wear their seat belts.For maximum protection in the event of a collision
always be in normal seated position with your back
against the backrest. Fasten your seat belt and
ensure that it is properly positioned on your body.Since the airbag inflates with considerable speed
and force, a proper seating and hands on steering
wheel position will help to keep you at a safe
distance from the airbag. Occupants who are
unbelted, out of position or too close to the airbag
can be seriously injured by an airbag as it inflates
with great force in the blink of an eye:
• 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.

tensioning retractor and airbag
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
Customer 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.• Airbags and “ETR’s” are designed to function
on a one-time-only basis. An airbag or
emergency tensioning retractor (ETR) that was
activated must be replaced.• Do not pass belts over sharp edges.
• Do not make any modification that could
change the effectiveness of the belts.• No modifications of any kind may be made to
any components or wiring of the “SRS”. This
includes changing or removing any component
or part of the “SRS”, the installation of
additional trim material, badges etc. over the
steering wheel hub, front passenger airbag
cover, door trim panels, or door frame trims,
and installation of additional electrical /
electronic equipment on or near “SRS”
components and wiring. Keep area between
airbags and occupants free from objects (e.g.
packages, purses, umbrellas, etc.).• Do not hang items such as coat hangers from
the coat hooks or handles over the door. These
items may turn into projectiles and cause head
and other injuries when curtain airbag is
deployed.• An airbag system component within the
steering wheel gets hot after the airbag has
inflated. Do not touch.

Wa r n i n g !
Do not adjust the steering wheel while driving.
Adjusting the steering wheel while driving could
cause the driver to lose the control of the vehicle.When leaving the vehicle always remove the
electronic key from the starter switch, and take the
KEYLESS-GO-card (if so equipped) with you. The steering wheel adjustment feature can also be
operated with the driver’s 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.

Storing inside rear view mirror positions
The inside rear view mirror positions are stored in
memory with the seat / steering wheel / exterior rear
view mirror positions and can be recalled when
necessary. See page 108 for notes on the memory
function.
Inside rear view mirror, automatic antiglare
Antiglare mode:
With the electronic key in starter switch position 2, the
mirror reflection brightness responds to changes in
light sensitivity.
With the gear selection lever in position “R”, or with the
interior light 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
inside rear view mirror.
The automatic antiglare function will not react for
example, if the rear window sun shade is in the raised
position.
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 to 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.
