Wipers
Notes
! Do not operate the wipers when the
windshield/rear window is dry. Dust that
accumulates on a windshield/rear window
might scratch the glass and/or damage the
wiper blades when wiping occurs on a dry
windshield/rear window. If it is necessary
to operate the wipers in dry weather
conditions, always operate the wipers with
washer fluid.

rain.
Intermittent wiping
Only switch on intermittent wiping under wet
weather conditions or in the presence of
precipitation.
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.
XTurn the combination switch to position
Ä or Å.
After the initial wipe, pauses between
wipes are controlled by the rain sensor
automatically.
Intermittent wiping is interrupted when the
vehicle is at a standstill and a front door is
opened. This protects persons getting into or
out of the vehicle from being sprayed.
Intermittent wiping will be continued when all
doors are closed andRthe automatic transmission is in drive
position D or reverse gear R

it is raining.
For information on filling up the washer
reservoir, see “Washer system and headlamp
cleaning system” (Y page 232).

attempting to remove any blockage:
R Stop the vehicle in a safe location.
R Remove the SmartKey from the starter
switch.
or
R Turn off the engine by pressing the
KEYLESS-GO start/stop button and

Power windows
Opening and closing
The door windows and the hinged quarter
windows are opened and closed electrically.
The switches for all door windows and the
hinged quarter windows are located on the
driver’s door control panel. The switches for
the respective door windows are located on
the front passenger door and the rear doors.
The hinged quarter windows can be operated
from the driver’s seat only.
i Operating the rear door windows from
the rear is not possible when you activate
the override switch ( Y page 60).GObserve Safety notes, see page 55.GWarning!
When opening or closing the windows, make
sure there is no danger of anyone being
harmed by the opening/closing procedure.
The door windows are equipped with the
express operation and automatic reversal
function. If in express operation mode a door
window encounters an obstruction that
blocks its path, the automatic reversal
function will stop the door window and open
it slightly.
The door windows operate differently when
the switch is pulled and held. See the “Closing
when a door window is blocked” section in
this chapter for details.
The closing of a door window can be
immediately halted by releasing the switch or,
if the switch was pulled past the resistance
point and released, by either pressing or
pulling the respective switch.
The closing of the hinged quarter windows can
be immediately halted by pressing or pulling
the switch.
If a window encounters an obstruction that
blocks its path in a circumstance where you
are closing the windows by pressing and
holding button & on the SmartKey or by
pressing and holding the lock button (vehicles
with KEYLESS-GO) on an outside door handle,
the automatic reversal function will not
operate.
Activate the override switch when children
are riding in the back seats of the vehicle. The
children may otherwise injure themselves,
e.g. by becoming trapped in the window
opening.

GWarning!
You could be injured when the hood is open –
even when the engine is turned off.
Parts of the engine can become very hot. To
prevent burns, let the engine cool completely
before touching any components on the
vehicle. Comply with all relevant safety
precautions.
GWarning!
To help prevent personal injury, stay clear of
moving parts when the hood is open and the
engine is running.
The radiator fan may continue to run for
approximately 30 seconds or may even
restart after the engine has been turned off.
Stay clear of fan blades.
GWarning!
Vehicles with gasoline engine:
The engine is equipped with a transistorized
ignition system. Because of the high voltage
it is dangerous to touch any components
(ignition coils, spark plug sockets, diagnostic
socket) of the ignition system

XThoroughly spray the vehicle with a
diffused jet of water.XDo not spray directly towards the
ventilation intake.XUse plenty of water and rinse the sponge
and chamois frequently.XRinse with clean water and dry with a
chamois thoroughly.
Do not allow cleaning agents to dry on the
finish.
Automatic car wash
You can have your vehicle washed in an
automatic car wash from the start. Brushless
car washes are preferable.
XTo protect the filter system, activate the air
recirculation mode using button d on
the climate control panel.
! Do not clean your vehicle in an automatic
touchless car wash which uses caustic
spray. Caustic spray will damage the paint
or ornamental moldings.
If the vehicle is very dirty, prewash it before
running it through the automatic car wash.
! Make sure the combination switch is set
to wiper setting $. Otherwise, the rain
sensor could activate and cause the wipers
to move unintentionally. This may lead to
vehicle damage.
Due to the width of the vehicle, fold in
exterior rear view mirrors prior to running
the vehicle through an automatic car wash
to prevent damage to the mirrors.
XWhen taking the vehicle through an
automatic conveyor-type car wash:
Make sure the automatic transmission
remains in neutral position N. Observe
instructions, see “Remaining in neutral
position N” ( Y page 115).
When leaving the automatic car wash, make
sure the mirrors are folded out.
After running the vehicle through an
automatic car wash, wipe any wax off of the
windshield and the wiper blade inserts. This
will prevent smears and reduce wiping noise
which can be caused by residual wax on the
windshield.
Ornamental moldingsXFor regular cleaning and care of ornamental
moldings, use a damp cloth.
! Do not use chrome cleaner on ornamental
moldings. Although ornamental moldings
may have chrome appearance, they could
be made of anodized aluminum that will be
damaged when cleaned with chrome
cleaner. Instead, use a damp cloth to clean
those ornamental moldings.
For very dirty ornamental moldings of
which you are sure are chrome-plated, use
a chrome cleaner. If in doubt whether an
ornamental molding is chrome-plated,
contact an authorized Mercedes-Benz
Center.
Headlamps, brake lamps, tail lamps,
side markers, turn signal lenses
XUse a mild vehicle wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water.
! Only use window cleaning solutions that
are suitable for plastic lamp lenses.
Window cleaning solutions which are not
suitable may damage the plastic lamp
lenses of the headlamps. Therefore, do not
use abrasives, solvents or cleaners that
contain solvents.
