42 Getting startedAdjustingWarning!
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 start-
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 re-
sult in an accident and/or serious personal
injury.
Warning!
G
Canada only: Children 12 years old and un-
der 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 in-
stalled in the vehicle to deactivate the front
passenger front air bag when it is properly
installed. Otherwise they will be struck by
the air bag when it inflates in a crash. If this
happens, serious or fatal injury will result.
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
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child. For addi-
tional information, see “Children in the vehi-
cle” (
page 88).
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.

The memory function (
page 134) 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.
i
Depending on the set height of the head re-
straint, the seat fore and aft position is
automatically pre-set.
i
Adjust the head restraint in such a way that
it is as close to the head as possible.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.
47 Getting started
Adjusting
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 198).
Exterior rear view mirrors
Warning!
G
Let the system complete the adjustment
procedure before setting the vehicle in mo-
tion. All steering wheel adjustment must be
completed before setting the vehicle in mo-
tion. Driving off with the steering wheel still
adjusting could cause the driver to lose con-
trol of the vehicle.
Warning!
G
In 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 liquid state and by apply-
ing plenty of water.
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). Ob-
jects in mirror are closer than they appear.
Check your interior rear view mirror or
glance over your shoulder before changing
lanes.

to turn off the engine while the gear selector le-
ver was not in positionP.
In addition, the message
Gear selector le-
ver in Park position appears in the multi-

!
Make sure the seat belt retracts fully so that
the seat belt and/or latch plate cannot get
caught or pinched in the door or in the seat
mechanism. This can damage the seat belt and
impair the effectiveness of the seat belt, and/or
cause damage to the door and/or door trim pan-
el. Such damage is not covered by the
Mercedes-Benz Limited Warranty.
Damaged seat belts must be replaced. Contact
an authorized Mercedes-Benz Center.
Warning!
G
To prevent possible personal injury, always
keep hands and fingers away from the door
openings when closing the doors. Be espe-
cially careful when small children are
around.
Before closing doors, make sure that there
is no possibility of someone getting caught
in a door during closing.Warning!
G
When leaving the vehicle, always take the
SmartKey or SmartKey with KEYLESS-GO*
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. A child’s un-
supervised access to a vehicle could result
in an accident and/or serious personal inju-
ry.
70 Safety and SecurityOccupant safetyAir bagsWarning!
G
Air bags are designed to reduce the poten-
tial of injury and fatality in certain frontal im-
pacts (front air bags), side impacts (side
impact air bags and window curtain air bags)
or rollovers (window curtain air bags). How-
ever, no system available today can totally
eliminate injuries and fatalities.
The activation of the air bags temporarily re-
leases a small amount of dust from the
air bags. This dust, however, is neither inju-
rious to your health, nor does it indicate a
fire in the vehicle. The dust might cause
some temporary breathing difficulty for peo-
ple with asthma 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 air bag inflates,
then get fresh air by opening a window or
door.
Warning!
G
To reduce the risk of injury when the front
air bags inflate, it is very important for the
driver and front passenger to always be in a
properly seated position and to wear their
respective 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 make sure that it is prop-
erly positioned on your body.
Since the air bag 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 air bag.
Occupants who are unbelted, out of position
or too close to the air bag can be seriously
injured or killed by an air bag as it inflates
with great force in the blink of an eye:
Sit properly belted in a nearly upright
position with your back against the seat
backrest.
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 air bag cover
on the steering wheel must be at least
10 in (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 contact your authorized
Mercedes-Benz Center.
Do not lean your head or chest close to
the steering wheel or dashboard.
Keep hands on the outside of steering
wheel rim. Placing hands and arms
inside the rim can increase the risk and
potential severity of hand/arm injury
when driver front air bag inflates.
Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.
