Warning!
When opening or closing the door 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 the door windows 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.
If a door window encounters an obstruction
that blocks its path in a circumstance where
you are closing the door 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 door window
opening.

Corrosion protection, such as MB
Anticorrosion Wax should be applied to the
engine compartment after every engine
cleaning. Before applying, all control linkage
bushings
and joints should be lubricated. The
poly-V-belt and all pulleys should be
protected from any wax.
Vehicle washing In the winter, thoroughly remove all traces of
road salt as soon as possible.
When

washing the vehicle underbody, do not
forget to clean the inner sides of the wheels.
i Vehicles with KEYLESS-GO:
If a door handle is hit by a strong jet of
water, and a SmartKey is within
approximately 3 ft (1 m) of the vehicle, it
could be inadvertently locked or unlocked.
Hand-wash
X Do not use hot water or wash your vehicle
in direct sunlight.
X Only use a soft, wet cloth or sponge to
clean the vehicle.
X Only use a mild vehicle wash detergent,
such as Mercedes-Benz approved Car
Shampoo.
X Thoroughly spray the vehicle with a
diffused jet of water.
X Do not spray directly towards the
ventilation intake.
X Use plenty of water and rinse the sponge
and chamois frequently.
X Rinse 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.
X To protect the filter system, activate the air
recirculation mode using button g 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.
X When taking the vehicle through an
automatic conveyor-type car wash:
Make sure the automatic transmission
remains in neutral position N.
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 moldings X
For 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. 218

Safety notes
G
Warning!
For safety reasons, switch off the wipers and
remove the SmartKey from the starter switch
(vehicles with KEYLESS-GO: Make sure the
vehicle’s on-board electronics have status 0)
before replacing a wiper blade. Otherwise, the
wiper motor could suddenly turn on and cause
injury. G
Warning!
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.
! To avoid damage to the hood, the wiper
arms should only be folded forward when
in the vertical position.
! Never open the hood when a wiper arm is
folded forward.
Hold on to the wiper when folding a wiper
arm back. If released, the force of the
impact from the tensioning spring could
crack the windshield.
Do not allow a wiper arm to contact the
windshield glass without a wiper blade
inserted.

this work carried out at an authorized
Mercedes-Benz Center. Placing wiper arms in vertical position
