Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the center of
the head restraint supports the back of the
head at eye level. This will reduce the poten-
tial for injury to the head and neck in the
event of an accident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.iAdjust the head restraint in such a way
that it is as close to the head as possi-
ble.

factory for U.S. vehicles. If you wish to
have it activated, contact an authorized
Mercedes-Benz Center.
The front passenger seat head restraint
automatically lowers after a few sec-
onds when the front passenger seat is
not occupied. This improves the
driver's outward view as well as the for-
ward view from the rear passenger
compartment.
When the front passenger seat is occu-
pied again, the front passenger head
restraint returns to the last set position
within a few seconds.
If the front passenger seat was moved
fore or aft while not being occupied,
the front passenger seat head restraint
returns to a position that corresponds
best with the seat's axial position when
the seat is occupied again.

wheel adjustment feature can be operated
when the driver’s door is open. Therefore,
do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.
Unsupervised use of vehicle equipment may
cause an accident and/or serious personal
injury.

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

Manually adjust the interior rear view
mirror.
For more information, see “Rear view mir-
rors” (
page 186).Exterior rear view mirror
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 only be
completely removed while in their liq-
uid state and by applying plenty of wa-
ter.
Warning!
G
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-
terior rear view mirror or glance over your
shoulder before changing lanes.

Fastening the seat belts
Warning!
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 passengers are
properly restrained, even those sitting in the
rear and 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 passengers should
always 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 air bags can only provide the
protection they were designed to afford if
the occupants are using their seat belts
(page 60).
Warning!
G
Children 12 years old and under must never
ride in the front seat, 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. Other-
wise they will be struck by the air bag when
it inflates in a crash. If this happens, serious
or fatal injury will result.

tive Corp.

3 Latch plate
Pull the seat belt smoothly from the
seat belt outlet.
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing 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 and top tether strap, or secured via
lower anchors and top tether strap, fully in
accordance with the child seat manufactur-
er’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 let more people ride in the vehicle
than there are seat belts available. Be sure
everyone riding in the vehicle is correctly re-
strained with a separate seat belt. Never use
a seat belt for more than one person at a
time.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
Read and observe the additional warning no-
tices printed in the “Safety and Security”
section (
page 64).


45 Getting started
Driving

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

Push latch plate3 into buckle2 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 posi-
tioned.


Make sure 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 Cen-
ter.

Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive with at least one window
fully open.
iYou can also use the “touch-start”
function. Turn the SmartKey to
position3 and release it again immedi-
ately. The engine then starts automati-
cally.

carry out the following steps:

If you are starting the engine with the
SmartKey, turn SmartKey in starter
switch to position0 and repeat starting
procedure.

If you are starting the engine with
KEYLESS-GO: Close any doors that
may be open to allow for better detec-
tion of the SmartKey with
