Adjusting
Seats
Warning!G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before
the vehicle is put into motion.
Warning!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 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
abdomen or neck. That could cause serious
or fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a position that is as upright as
possible and the seat belts are properly po-
sitioned on the body.Warning!G
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 48).
Observe the following points:
Adjust the backrest until your arms are
slightly angled when holding the steer-
ing wheel.
Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The po-
sition should be as far back as possible
with the driver still able to operate the
controls properly.
Adjust the head restraint so that it is as
close to the head as possible and the
center of the head restraint supports
the back of the head at eye level.
Never place hands under the seat or
near any moving parts while a seat is be-
ing adjusted.
Failure to do so could result in an accident
and/or serious personal injury.

Warning!G
When leaving the vehicle, always remove the
SmartKey or the 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
starter 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 re-
sult in an accident and/or serious personal
injury.
Warning!G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats
whenever possible. Regardless of seating
position, children 12 years old and under
must be seated and properly secured in an
appropriate infant or toddler restraint, or
booster seat recommended for the size and
weight of the child. For additional informa-
tion, see “Children in the vehicle”
(
page 82).
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.
iThe memory function (page 123) lets you
store the settings for the seat position together
with the settings for the steering wheel and the
exterior rear view mirrors.
!When moving the seat, make sure there are
no items in the footwell or behind the seats, oth-
erwise you could damage the seats.

Steering wheel
Warning!G
When folding back the side cushions, never
reach between the side cushion and the
mounting post. You could otherwise be
trapped.
iAdjust the head restraint in such a way that
it is as close to the head as possible.
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 the SmartKey with
KEYLESS-GO* from the starter switch, take
it with you, and lock your vehicle.
Even with the SmartKey removed from the
starter switch or the SmartKey with
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.
48 Getting started
Driving
Fastening the seat belts
Warning!G
Make sure that absolutely no objects are ob-
structing the pedals 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 that the pedals still
have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury.
Warning!G
Always fasten your seat belt before driving
off. Always make sure all of your passengers
are properly restrained, even those sitting in
the rear.
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 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 76).
Warning!G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front
seating position. Thus, we strongly recom-
mend that children be placed in the rear
seats. Regardless of seating position, chil-
dren 12 years old and under must be seated
and properly secured in an appropriate in-
fant or toddler restraint, or booster seat rec-
ommended for the size and weight of the
child. For additional information, see “Chil-
dren in the vehicle” (
page 82).
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
restrained with a separate seat belt. Never
use a seat belt for more than one person at
a time.
50 Getting started
Driving
Belt outlet height adjustment
1Release button
Press release button1 and move the
seat belt height adjuster upward or
downward.
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 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 or toddler restraints or children
in booster seats, always follow the
child seat manufacturer’s instructions.
Check your seat belt periodically dur-
ing t ravel to ma ke sure that it is proper-
ly 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.
73 Safety and Security
Occupant safety
If the 75 indicator lamp is illu-
minated, the front passenger front air bag is
deactivated and will not be deployed.
If the 75 indicator lamp is not
illuminated, the front passenger front air
bag is activated and will be deployed:
in the event of certain frontal impacts
if impact exceeds a preset deployment
threshold
independently of the side impact
air bags
If the front passenger front air bag is
deployed, the rate of inflation will be
influenced by:
the rate of relevant vehicle deceleration
as assessed by the air bag control unit
front passenger’s weight category as
identified by the Occupant Classification
System (OCS)
Warning!G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats
whenever possible. Regardless of seating
position, children 12 years old and under
must be seated and properly secured in an
appropriate infant or child restraint recom-
mended for the size and weight of the child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt, the seat
belt and top tether strap, or lower anchors
and top tether strap, fully in accordance
with the child seat manufacturer’s instruc-
tions.
Always sit as upright as possible, properly
use the seat belts and for children 12 years
old and under, use an appropriately sized in-
fant restraint, toddler restraint, or booster
seat recommended for the size and weight
of the child.
Children can be killed or seriously injured by
an inflating air bag. Note the following im-
portant information when circumstances re-
quire you to place a child in the front
passenger seat:
Your vehicle is equipped with air bag
technology designed to turn off the front
passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropri-
ate child restraint on the front passen-
ger seat.
A child in a rear-facing child restraint on
the front passenger seat will be serious-
ly injured or even killed if the front pas-
senger front air bag inflates in a collision
which could occur under some circum-
stances, even with the air bag technolo-
gy installed in your vehicle. The only
means to completely eliminate this risk
is to never place a child in a rear-facing
child restraint in the front seat. We
therefore strongly recommend that you
always place a child in a rear-facing
child restraint in the back seat.
