This supplies power for all electrical
consumers. All lamps in the instrument
cluster (except low beam headlamp in-
dicator lamp, high beam headlamp indi-
cator lamp, and turn signal indicator
lamps unless activated) 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 nec-
essary. If a lamp in the instrument clus-
ter remains on after starting the engine
or comes on while driving, see “Lamps
in instrument cluster” (
page 380).For information on starting the engine us-
ing the KEYLESS-GO start/stop button,
see “Starting with KEYLESS-GO*”

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 seat belt would apply force at
the abdomen or neck. That could cause se-
rious or fatal injuries. The seat back and seat
belts provide the best restraint when the
wearer is in a nearly upright position and
seat belts are properly positioned on the
body.
Warning!
G
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 49).
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 to the rear as pos-
sible, consistent with ability to properly
operate controls.


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.

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.

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.

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.

49 Getting started
Driving
Driving
Fastening the seat beltsWarning!
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 82).
