!If the windshield wipers leave smears on the
windshield after the car has been driven through
an automatic car wash, then wax or other resi-
due is on the windshield. Shortly after washing
the car in an automatic car wash, clean the wind-
shield with windshield washer fluid
(
page 373).
!Do not operate the wipers when the wind-
shield is dry. Dust that accumulates on a wind-
shield might scratch the glass and/or damage
the wiper blades when wiping occurs on a dry
windshield. If it is necessary to operate the wip-
ers in dry weather conditions, always operate
the wipers with windshield washer fluid
(
page 373).
!If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off immediate-
ly.

For safety reasons, stop the vehicle in a safe
location,

turn off the engine by turning the
SmartKey to position0 and withdraw
SmartKey from starter switch
or

turn off the engine by pressing the
KEYLESS-GO* start/stop button
(
page 337) and open the driver’s door
(with the driver’s door open, starter
switch is in position0, same as with
SmartKey removed from starter switch)
before attempting to remove any blockage.

Remove blockage.

Turn the windshield wipers on again.If the windshield wipers fail to function at all in
the combination switch position u,

set the combination switch to the next high-
er wiper speed

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
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause un-
consciousness and possible death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive with at least one window
fully open.

The red brake warning lamp 0
(USA only) or ! (Canada only) in the
instrument cluster goes out.After a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter to reach
its operating temperature earlier.
iWait for the gear selection process to com-
plete before setting the vehicle in motion.
iShifting from gear position P to position R,
N, or D is only possible with the brake pedal de-
pressed. Without the brake pedal depressed, the
gear selector lever can be moved, but the park-
ing pawl remains engaged, not allowing shifting
to occur.
!If you hear a warning signal, the red indica-
tor lamp 0 (USA only) or ! (Canada only)
in the instrument cluster flashes and the mes-
sage “Please release parking brake” appears in
the multifunction display when driving off, you
are driving with the electronic parking brake en-
gaged, or you are carrying out an emergency
brake application with the electronic parking
brake.

Warning!G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.
Warning!G
It is dangerous to shift the gear selector le-
ver out of P or N if the engine speed is high-
er than idle speed. If your foot is not firmly
on the brake pedal, the vehicle could accel-
erate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and when
your right foot is firmly on the brake pedal.
!Shift the automatic transmission toP or R
only when the vehicle is stopped in order to avoid
damaging the transmission.
!Do not run cold engine at high engine
speeds. Running a cold engine at high engine
speeds may shorten the service life of the en-
gine.
This is not covered by the Mercedes-Benz
Limited Warranty.
!Simultaneously depressing the accelerator
pedal and applying the brakes reduces engine
performance and causes premature brake wear
and drivetrain wear which is not covered by the
Mercedes-Benz Limited Warranty.
