iWhen you switch on the ignition, the
indicator and warning lamps (except
high beam headlamp indicator lamp
and turn signal indicator lamps if acti-
vated) in the instrument cluster come

switch position0 for an extended peri-
od of time, it can no longer be turned in
the starter switch.

Remove the SmartKey from the

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 place hands under the seat or near
any moving parts while a seat is being ad-
justed.
Never ride in a moving vehicle with the seat
back in an excessively reclined position as
this can be dangerous. You could slide un-
der the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen or neck.
That could cause serious or fatal injuries.
The seat back and seat belts provide the
best restraint when the wearer is in a nearly
upright position and belts are properly posi-
tioned on the body. Your seat must be ad-
justed so that you can correctly fasten your
seat belt (
page 45).
Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it

Even with the SmartKey removed from the
starter switch or the vehicle, the seats can
be operated. Therefore, do not leave chil-
dren unattended in the vehicle, or with ac-
cess to an unlocked vehicle. Unsupervised
use of vehicle equipment may cause an ac-
cident and/or serious personal injury.

mirrors before driving so that you have a
good view of the road and traffic condi-
tions.Interior rear view mirror

Manually adjust the rear-view mirror.
For more information, see “Rear view mir-
rors” (
page 179).
Exterior rear view mirrors
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.!Electrolyte drops coming into contact
with the vehicle paint finish can be
completely removed only while in the
liquid state and by applying plenty of
water.
Warning!
G
Exercise care when using the passen-
ger-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-
terior rear view mirror or glance over your
shoulder before changing lanes.

Driving
Fastening the seat beltsWarning!
G
Do not lay any objects in the driver’s foot-
well. Be careful that floor mats or carpets in
the driver’s footwell have sufficient clear-
ance for the pedals.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate.Warning!
G
Always fasten your seat belt before driving
off. Always make sure your passenger is
properly restrained, even pregnant women.
Failure to wear and properly fasten and po-
sition your seat belt greatly increases your
risk of injuries and their likely severity in an
accident. You and your passenger should al-
ways wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled. Without
your seat belt buckled, you are much more
likely to hit the interior of the vehicle or be
ejected from it. You can be seriously injured
or killed.
In the same crash, the possibility of injury or
death is lessened if you are wearing your
seat belt. The airbags can only provide the
protection they were designed to afford if
the occupants are using their seat belts
(page 69).
Warning!
G
Children 12 years old and under must never
ride in this vehicle, except in a
Mercedes-Benz authorized BabySmart
TM1

compatible child seat, which operates with
the BabySmart
TM system installed in the ve-
hicle to deactivate the passenger front air-
bag when it is properly installed. Otherwise
they will be struck by the airbag when it in-
flates in a crash. If this happens, serious or
fatal injury will result.
Infants and small children must be seated in
an appropriate BabySmart
TM compatible in-
fant or child restraint system, which is prop-
erly secured with the vehicle’s seat belt and
top tether strap, 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.Warning!
G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this 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 ab-
domen or neck. That could cause serious or
even fatal injuries. The seat backrest and
seat belt provide the best restraint when the
wearer is in a nearly upright position and the
belt is properly positioned on the body.
Warning!
G
Never let more people ride in the vehicle
than there are seat belts available. Be sure
everyone riding in the vehicle is correctly
restrained with a separate seat belt. Never
use a seat belt for more than one person at
a time.Warning!
G
Read and observe the additional warning no-
tices printed in the “Safety and Security”
(page 67) and (
page 69).


47 Getting started
Driving

Pull the belt smoothly from seat belt
holder 1.

Place the shoulder portion of the belt
across the top of your shoulder and the
lap portion across your hips.

Push latch plate2 into buckle3 until
it clicks.

If necessary, tighten the lap portion to
a snug fit by pulling shoulder portion
up.
Proper use of seat belts


Do not twist the belt when fastening.


Adjust seat belt so that the shoulder
portion is located as close as possible
to the middle of the shoulder (it should
not touch the neck). Never pass the
shoulder portion of the belt under your
arm.


Position the lap belt as low as possible
on your hips (over hip joint) and not
across the abdomen.


Place the seat backrest in a nearly up-
right position.


Never use a seat belt for more than one
person at a time.


Do not fasten a seat belt around a per-
son and another object at the same
time. When using a seat belt to secure
infant or toddler restraints or children
in booster seats, always follow the
child seat manufacturer’s instructions.


Check your seat belt during travel to
make sure that it is properly
positioned.


Make sure that the seat belt is always
fitted snugly. Take special care of this
when wearing loose clothing.
Warning!
G
Do not pass belts over sharp edges. They
could tear.
Do not allow the belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the belts.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Damaged seat belts or belts that were highly
stressed in an accident must be replaced.
Contact an authorized Mercedes-Benz
Center.

(such as garage) which are not properly ven-
tilated. If you think that exhaust gas fumes
are entering the vehicle while driving, have
the cause determined and corrected imme-
diately. If you must drive under these condi-
tions, drive only with at least one window
fully open.
