lamps unless activated) in the instru-
ment cluster come on. If a lamp in the
instrument cluster fails to come on
when the ignition is switched on, have
it checked and replaced if necessary.
If a lamp in the instrument cluster
remains on after starting the engine or
comes on while driving, refer to “Lamps
in the instrument cluster”
(
page 342).
3Starting position
!A side window will not work if it is blocked
with ice or if the battery needs charging. If you
cannot shut a door, do not force it or you could
damage the door or the side window.
Fix whatever is affecting the window before
trying to shut the door.
Warning!G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised ac-
cess to a vehicle could result in an accident
and/or serious personal injury.
iWhen you switch on the ignition, the indica-
tor and warning lamps (except high beam head-
lamp indicator lamp and turn signal indicator
lamps unless activated) in the instrument cluster
come on. The indicator and warning lamps
(except high beam headlamp indicator lamp and
turn signal indicator lamps if activated) should go
out when the engine is running. This indicates
that the respective systems are operational.

er switch or the SmartKey with
KEYLESS-GO* removed from the vehicle,
the power seats can be operated when the
respective door is open. Therefore, do not
leave children unattended in the vehicle, or
with access to an unlocked vehicle. A child’s
unsupervised access to a vehicle could
result in an accident and/or serious person-
al injury.
Warning!G
Children 12 years old and under must be
seated and properly secured in an appropri-
ately sized infant restraint, toddler restraint,
or booster seat recommended for the size
and weight of the child For additional infor-
mation, see “Children in the vehicle”
(
page 84).
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.
46 Getting started
Adjusting
Head restraint tilt
Manually adjust the angle of the head re-
straint.
Push or pull on the lower edge of the
head restraint cushion.
For more information on seats, see “Seats”
(
page 124).
Steering wheel
Make sure that
you can reach the steering wheel with
your arms slightly bent at the elbows
you can move your legs freely
all displays (including malfunction and
indicator lamps) on the instrument
cluster are clearly visible
Warning!G
Do not adjust the steering wheel while driv-
ing. Adjusting the steering wheel while driv-
ing could cause the driver to lose control of
the vehicle.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle.
Even with the SmartKey or the SmartKey
with KEYLESS-GO* removed from the

KEYLESS-GO* removed from the vehicle,
the steering wheel adjustment feature can
be operated when the driver’s door is open.
Therefore, do not leave children unattended
in the vehicle, or with access to an unlocked
vehicle. A child’s unsupervised access to a
vehicle could result in an accident and/or
serious personal injury.
iThe memory function (page 129) lets you
store the settings for the steering wheel together
with the settings for the driver’s seat position
and the exterior rear view mirrors.
50 Getting started
Driving
Fastening the seat belts
Warning!G
Make sure that absolutely no objects are
obstructing the pedal’s range of movement.
Keep the driver’s footwell clear of all obsta-
cles. If there are any floormats or carpets in
the footwell, make sure the pedals still have
sufficient clearance.
During sudden driving or braking maneu-
vers, the objects could get caught between
the pedals. You could then no longer brake
or accelerate. This could lead to accidents
or injury.Warning!G
Always fasten your seat belt before driving
off. Always make sure your passenger is
properly restrained.
Failure to wear and properly fasten and
position your seat belt greatly increases
your risk of injuries and their likely severity
in an accident. You and your passenger
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 68).
Warning!G
Children 12 years old and under must be
seated and properly secured in an appropri-
ate infant restraint, toddler restraint, or
booster seat recommended for the size and
weight of the child. For additional informa-
tion, see “Children in the vehicle”
(
page 84).
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.
52 Getting started
Driving
Proper use of seat belts
Do not twist the seat belt when fasten-
ing.
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 seat 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 position
that is as upright as possible.
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 restraints, toddler restraints or
children in booster seats, always follow
the child seat manufacturer’s instruc-
tions.
Check your seat belt during travel to
make sure that it is properly
positioned.
Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.
Warning!G
Do not pass seat belts over sharp edges.
They could tear.
Do not allow the seat belt to get caught in
the door or in the seat adjustment
mechanism. This could damage the
seat belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the seat 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 seat belts that were
highly stressed in an accident must be
replaced. Contact an authorized
Mercedes-Benz Center.
68 Safety and Security
Occupant safety
In this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
The restraint systems are
Seat belts (page 79)
Child restraints (page 85)
Additional protection potential provided by
Supplemental Restraint System (SRS)
with
Air bags (page 70)
Air bag control unit (with crash
sensors)
Emergency Tensioning Device
(ETD) for seat belts (
page 82)
Roll bar (page 83)Air bag system components with
Passenger front air bag off indicator
lamp (
page 78)
Passenger seat with Occupant
C
lassification System (OCS)
(
page 74)
Although independent systems, their
protective functions work in conjunction
with each other.The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates detection of malfunctions.
The
1indicator lamp in the instrument
cluster comes on when the ignition is
switched on and goes out no later than a
few seconds after the engine has been
started.
The SRS components are in operational
readiness if the
1indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the
1indicator lamp:
fails to go out after approximately
4 seconds after the engine was started
does not come on at all
comes on after the engine was started
or while driving

traveling with you in the vehicle and restraint
systems for infants and children, see “Children

71 Safety and Security
Occupant safety
Occupants, especially children, should
never lean their heads in the area of the
door where the head-thorax air bag in-
flates. This could result in serious inju-
ries or death should the air bag be
deployed. Always sit as upright as possi-
ble, properly use the seat belts and an
appropriately sized infant restraint,
toddler restraint, or booster seat
recommended for the size and weight of
the child.
Failure to follow these instructions can
result in severe injuries to you or other
occupants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety in-
formation. Be sure to give the buyer this
Operator’s Manual.Warning!G
There is a possibility of a head-thorax air bag
related injury if occupants, especially chil-
dren, are not properly seated or restrained
when next to a head-thorax air bag 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
head-thorax air bag inflates. This could
result in serious injuries or death should
the head-thorax air bag be deployed.
(2) Always sit as upright as possible, prop-
erly use the seat belts and for children
12 years old or under, use an appropri-
ately sized infant restraint, toddler
restraint, or booster seat recommended
for the size and weight of the child.
(3) Always wear seat belts properly.
If you believe that, even with the use of
these guidelines, it would be safer for your
passenger seat occupants to have the pas-
senger side head-thorax air bag deactivated,
then deactivation can be accomplished
upon your written election to do so at an
authorized Mercedes-Benz Center at an
additional cost.
Please contact your local authorized
Mercedes-Benz Center or call the Customer
Assistance Center (in the USA) at
1-800-FOR-MERCedes (1-800-367-6372),
or Customer Service (in Canada) at
1-800-387-0100 for details.
iAir bags are designed to activate only in cer-
tain frontal impacts (front air bags, driver-side
knee bag) and side impacts (head-thorax air
bags) which exceed preset thresholds. Only
during these events, will they provide their
supplemental protection.
The driver and passenger should always wear
their seat belts. Otherwise it is not possible for
the air bags to provide their supplemental
protection.
