For your protection, drive only with properly
positioned head restraints.
Adjust head restraint to support the back of
the head approximately at ear level.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.
Warning!
G
Do not adjust the steering wheel while driv-
ing. Adjusting the steering wheel while driv-
ing, or driving without the adjustment
locked could cause the driver to lose control
of the vehicle.
When leaving the vehicle, always remove the
key from the starter switch and lock your ve-
hicle.
The electrical steering wheel adjustment
feature* can also be operated with the driv-
er’s door open. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment may cause an accident
and/or serious personal injury.

Warning!
G
In the case of an accident liquid electrolyte
may escape the mirror housing if the mirror
glass breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.

Exercise care when using the passenger
side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
side rear view mirror or glance over your
shoulder before changing lanes. !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.

!If an exterior rear view mirror housing
is forcibly pushed forward or backward,
reposition it by applying firm pressure
until it snaps into place. The mirror
housing is now properly positioned and
you can adjust the mirror normally.

Warning!
G
Vehicles with automatic transmission: It is
dangerous to shift the selector lever out ofP
or N if the engine speed is higher than idle
speed. If your foot is not firmly on the brake
pedal, the vehicle could accelerate quickly
forward or in reverse. You could lose control
of the vehicle and hit someone or some-
thing. Only shift into gear when the engine is
idling normally and when your right foot is
firmly on the brake pedal.Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.

Wait until the vehicle is stationary before re-
moving the key from the starter switch. The
vehicle cannot be steered when the key is
removed.Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
system. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to stop or steer the vehi-
cle.
Warning!
G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before turning off
the engine and leaving the vehicle always:

Keep right foot on brake pedal.


Firmly depress parking brake pedal.


Move the selector lever to positionP
(manual transmission: first or reverse
gear).


Slowly release brake pedal.


When parked on an incline, turn front
wheels towards road curb.


Turn the key to starter switch position0
and remove.


Take the key and lock vehicle when leav-
ing.

57 Safety and Security
Occupant safety
Airbags
Warning!
G
In the event that the SRS malfunction indica-
tor lamp lights up during driving or does not
come on at all, the SRS may not be opera-
tional. For your safety, we strongly recom-
mend that you visit an authorized
Mercedes-Benz Center immediately to have
the system checked; otherwise the SRS may
not be activated when needed in an acci-
dent, which could result in serious or fatal
injury, or it might deploy unexpectedly and
unnecessarily which could also result in inju-
ry.
Improper work on the restraint systems, in-
cluding incorrect installation and removal,
can lead to possible injury through an unin-
tended activation of the SRS.
In addition, through improper work there is
a risk of rendering the SRS inoperative or
causing unintended airbag deployment.
W o r k o n t h e S R S m u s t t h e r e f o r e o n l y b e p e r -
formed by an authorized Mercedes-Benz
Center.
Warning!
G
Airbags are designed to reduce the potential
of injury in certain frontal (front airbags) im-
pacts, or side (side impact and head protec-
tion window curtain airbags) impacts which
may cause significant injuries. However, no
system available today can totally eliminate
injuries and fatalities.
The activation of the SRS temporarily releas-
es a small amount of dust from the airbags.
This dust, however, is neither injurious to
your health, nor does it indicate a fire in the
vehicle. The dust might cause some tempo-
rary breathing difficulty for people with asth-
ma or other breathing trouble. To avoid this,
you may wish to get out of the vehicle as
soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of the
vehicle after the airbag inflates, then get
fresh air by opening a window or door.
Warning!
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 your
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. Oc-
cupants who are unbelted, out of position or
too close to the airbag can be seriously in-
jured 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 seat back-
rest.

58 Safety and SecurityOccupant safety

Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion of vehicle controls. The distance
from the center of the driver’s breast-
bone 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 combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see your authorized
Mercedes-Benz Center.


Do not lean with your head or chest
close to the steering wheel or dash-
board.


Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side 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 seat belts
and appropriate size infant or child re-
straint 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 deacti-
vate 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, seri-
ous or fatal injury will result.
Failure to follow these instructions can re-
sult in severe injuries to you or other occu-
pants.
If you sell your vehicle you are responsible
to make the buyer aware of these points. Be
sure to give the buyer this Operator’s Manu-
al.
Warning!
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 any
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 prop-
erly 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 or rear
