When you switch on the ignition, all lamps in
the instrument cluster come on. The high-
beam headlamp indicator lamp and turn
signal indicator lamps will only come on if activated. 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 instrument cluster”
(Y page 450).

Always remove the SmartKey from the
starter switch when the engine is not in
operation.
This will help to prevent accelerated vehicle
battery discharge or a completely
discharged vehicle battery.
If the SmartKey cannot be turned in the
starter switch, the vehicle battery may not be
sufficiently charged.

Safety notes
G
Warning!
In order to avoid possible loss of vehicle
control the

following must be done before the
vehicle is put into motion:
R seat adjustment
R head restraint adjustment
R steering wheel adjustment
R rear view mirror adjustment
R fastening of seat belts G
Warning!
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 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 seat belts are properly
positioned on the body. G
Warning!
Your seat must be adjusted so that you can
correctly fasten your seat belt. Observe the following points:
R
Adjust the

seat backrest until your arms are
slightly angled when holding the steering
wheel.
R Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far back as possible
with the driver still able to operate the
controls properly.
R Adjust the head restraint so that it is as
close to the head as possible. The center of
the head restraint must support the back of
the head at eye level.
R Never place hands under the seat or near
any moving parts while a seat is being
adjusted.
Failure to do so could result in an accident
and/or serious personal injury. G
Warning!
The power seats can be operated at any time.
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. G
Warning!
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
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 additional
information, see “Children in the vehicle”.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/ 264

Warning!
Always ensure that no one can become
trapped or injured when the seat is moving. In
case potential danger exists, the procedure
can be interrupted by moving the seat
adjustment switch in the door control panel
or by moving the release lever again. G
Warning!
The seat belts provide protection only with the
seat backrest locked in place. Therefore, the
seat backrest must be locked in place with the
vehicle in motion. Do not drive the vehicle
when the seat backrest is not locked in place.
If the warning message:
Lock Seat Backrest Front Right
or
Lock Seat Backrest Front Left
is displayed in the multifunction display, then
the respective seat backrest is not engaged
in its lock. Carefully slow down, and drive with
caution to an area which is in a safe distance
from the roadway. Always provide sufficient
room behind the seat backrest and fold the
seat backrest all the way back until it locks in
place.
The warning message is no longer displayed
as soon as the seat backrest is locked in
place. If both seat backrests are locked in
place and the warning message is still
displayed, have the system checked at an
authorized Mercedes-Benz Center
immediately.

Notes
! Do not operate the wipers when the
windshield is dry. Dust that accumulates on
a windshield might scratch the glass and/
or damage the wiper blades when wiping
occurs on a dry windshield. If it is necessary
to operate the wipers in dry weather
conditions, always operate the wipers with
washer fluid.
! If the windshield wipers leave smears on
the windshield after the car has been driven
through an automatic car wash, then wax
or other residue is on the windshield.
Shortly after washing the car in an
automatic car wash, clean the windshield
with washer fluid. Windshield wipers

Intermittent wiping Only switch on intermittent wiping under wet
weather conditions or in the presence of

When
you

select intermittent wiping, the rain
sensor is activated. The rain sensor sets a
suitable wiping interval depending on the
wetness of the sensor surface automatically.
! Do not leave windshield wipers on an
intermittent setting when the vehicle is
taken to an automatic car wash or during
windshield cleaning. Windshield wipers will
operate in the presence of water sprayed
on the windshield, and windshield wipers
may be damaged as a result.
! If you have set intermittent wiping, dirt on
the surface of the rain sensor or optical
effects may cause the windshield wipers to
wipe in an undesired fashion. This could
then damage the windshield wiper blades
or scratch the windshield. You should
therefore switch off the windshield wipers
when weather conditions are dry.
X Turn the combination switch to position

After the initial wipe, pauses between
wipes are controlled by the rain sensor
