Windshield wipers
Switching the windshield wipers on/
off
GWARNING
Wiper blades are components that are subject
to wear and tear. Replace the wiper blades
twice a year, preferably in the spring and fall.
Otherwise the windshield will not be wiped
properly. As a result, you may not be able to
observe surrounding traffic conditions and
could cause an accident.
! Do not operate the windshield wipers
when the windshield is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windshield can
scratch the glass if wiping takes place when
the windshield is dry.
! If the windshield wipers leave smears on
the windshield after the vehicle has been
washed in an automatic car wash, wax or
other residues may be the reason for this.
Clean the windshield using washer fluid
after washing the vehicle in an automatic
car wash.

windshield using washer fluidXSwitch on the ignition.XTurn the combination switch to the
corresponding position.
! Vehicles with a rain sensor: if the
windshield becomes dirty in dry weather
conditions, the windshield wipers may be
activated inadvertently. This could then
damage the windshield wiper blades or
scratch the windshield.
For this reason, you should always switch
off the windshield wipers in dry weather.
In the Ä or Å position, the appropriate
wiping frequency is set automatically
according to the intensity of the rain. In
the Å position, the rain sensor is more
sensitive than in the Ä position, causing
the windshield wipers to wipe more
frequently.
Replacing the wiper blades
Important safety notes
GWARNING
For safety reasons, switch off the wipers and
remove the SmartKey from the starter switch
before replacing a wiper blade. Otherwise, the
wiper motor could suddenly turn on and cause
injury.
! To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper.
! Never open the hood if a windshield wiper
arm has been folded away from the
windshield.
Never fold a windshield wiper arm without
a wiper blade back onto the windshield.

Setting the air vents
Important safety notes
GWARNING
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold (depending on the set temperature). This
could cause burns or frostbite to unprotected
skin in the immediate area of the air vents.
Always keep sufficient distance between
unprotected parts of the body and the air
vents. If necessary, use the air distribution
adjustment to direct the air to air vents in the
vehicle interior that are not in the immediate
area of unprotected skin.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet grille on the hood and in
the engine compartment on the front-
passenger side free of blockages, such as
ice, snow or leaves.
R never cover the air vents or air intake grilles
in the vehicle interior.
i You can tilt the adjuster for the air vents
vertically or horizontally to alter the
direction of the airflow.
i For optimal climate control in the vehicle,
open the air vents completely and set the
adjusters to the central position.

multifunction display when the engine is
switched off, the engine was switched off
automatically. However, all vehicle systems
remain active. If you open the door, unfasten
your seat belt or remove your foot from the
brake pedal, the engine will automatically
start. The vehicle may begin moving. There is
a risk of an accident.

automatic engine switch-off have been
fulfilled ( Y page 135) and the ¤ symbol is
shown in the multifunction display. In
addition, the Stop/Start active message
is shown in the AMG menu in the
multifunction display.
If not all conditions for automatic engine
switch-off are fulfilled, the border of the ECO
symbol disappears in the multifunction
display. In addition, the Stop/Start
inactive message is shown in the AMG
menu in the multifunction display.
