shield 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.

XSwitch on the ignition.
XTurn the combination switch to the corre-
sponding position.
In the ÅorÄ position, the appropriate
wiping frequency is set automatically according
to the intensity of the rain. In the Åposition,
the rain sensor is more sensitive than in the
Ä position, causing the windshield wiper to
wipe more frequently.
The washer fluid is fed through the wiper blades;
when the screen is wiped with washer fluid
î, the water is emitted directly from the
blades.
If you push and hold the combination switch
beyond the point of resistance in direction of
arrow B, the manual wash program is activa-
ted. If you push and hold the combination switch
briefly beyond the point of resistance in direc-
tion of arrow B, the automatic wash program is
activated.
If the wiper blades are worn, the windshield will
no longer be wiped properly. This could prevent
you from observing the traffic conditions.
Replacing the wiper blades
Important safety notes
GWARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
!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 wind-
shield.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release the
windshield wiper arm without a wiper blade
and it falls onto the windshield, the windshield
may be damaged by the force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
!Always position the windshield wiper arms
vertically before folding them away from the
windshield. By doing so, you will avoid dam-
age to the hood.
Replacing the wiper blades
Moving the wiper arms to a vertical posi-
tion
XSwitch off the engine.
XRemove your foot from the brake pedal.
XSet the windshield wiper to the °position
on the combination switch.
XPress the Start/Stop button repeatedly until
the windshield wiper starts.
XWhen the wiper arms are vertical to the hood,
press the Start/Stop button.
XFold the wiper arm away from the windshield.

Example: checking the coolant level
XPark the vehicle on a level surface.
Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down.
XTurn the SmartKey to position2in the ignition
lock (Ypage 124).
or
XOn vehicles with KEYLESS-GO, press the
Start/Stop button twice (Ypage 124).
XCheck the coolant temperature display in the
instrument cluster (Ypage 188).
The coolant temperature must be below
158 ‡ (70 †).
XTurn the SmartKey to position 0in the ignition
lock (Ypage 124).
or
XPress the Start/Stop button once on vehicles
with KEYLESS-GO (Ypage 124).
XSlowly turn cap :counter-clockwise and to
relieve excess pressure.
XTurn cap :further counter-clockwise and
remove it.
If the coolant is at the level of marker bar =
in the filler neck when cold, there is enough
coolant in coolant expansion tank ;.
If the coolant level is approximately 0.6 in
(1.5 cm) above marker bar =in the filler neck
when warm, there is enough coolant in expan-
sion tank ;.
XIf necessary, add coolant that has been tested
and approved by Mercedes-Benz.
XReplace cap :and turn it clockwise as far as
it will go.
For fu rther i
nformation on coolant, see
(Ypage 332).
Adding washer fluid to the windshield
washer system
GWARNING
Windshield washer concentrate could ignite if it comes into contact with hot engine compo-
nents or the exhaust system. There is a risk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
Example: adding fluid to the windshield
washer system
XTo open: pull cap:upwards by the tab.
XPlace cap :on the edge of the filler neck and
engage in place.
XAdd the premixed washer fluid.
XTo close: press cap :onto the filler neck
until it engages.
If the washer fluid level drops below the recom-
mended minimum fluid level of 1.1 US qt (1.0 l),
a message appears in the multifunction display
prompting you to add washer fluid (
Ypage 230).

The ASSYST PLUS service interval display

Maintenance and care

!Always maintain a distance of at least
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information about the
correct distance is available from the equip-
ment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
Do not aim directly at any of the following:
RTires
RDoor gaps, joints etc.
RSoft top
RWind deflector net
RElectrical components
RBattery
RConnectors
RLamps
RSeals
RTrim elements
RVentilation slots
Damaged seals or electrical components can
lead to leaks or failures.
!If the SmartKey is within the rear detection
range of KEYLESS-GO, the following situa-
tions, for example, could lead to the uninten-
tional opening of the trunk:
Rusing a car wash
Rusing a power washer
Make sure that the SmartKey is at least 10 ft
(3 m) away from the vehicle.
Cleaning the paintwork
!Do not affix:
Rstickers
Rfilms
Rmagnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected by corrosion and damage caused by inadequate
care cannot always be completely repaired. In
such cases, visit a qualified specialist workshop.
XRemove dirt immediately, where possible,
while avoiding rubbing too hard.
XSoak insect remains with insect remover and
rinse off the treated areas afterwards.
XSoak bird droppings with water and rinse off
the treated areas afterwards.
XRemove coolant, brake fluid, tree resin, oils,
fuels and greases by rubbing gently with a
cloth soaked in petroleum ether or lighter
fluid.
XUse tar remover to remove tar stains.
XUse silicone remover to remove wax.
If water no longer forms "beads" on the paint
surface, use the paint care products recommen-
ded and approved by Mercedes-Benz. This is the
case approximately every three to five months,
depending on the climate conditions and the
care product used.
The cleaning product Paint Cleaner, which has
been recommended and approved by
Mercedes-Benz, should be used when dirt has
penetrated the paint surface.
Also use Paint Cleaner on paint that has become
dull.
Do not use these care products in the sun or on
the hood while the hood is hot.
XUse a suitable touch-up stick, e.g. MB Touch-
Up Stick, to repair slight damage to the paint- work quickly and provisionally.
Matte finish care
!Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to shine.
!The following may cause the paint to
become shiny and thus reduce the matte
effect:
Rstrong rubbing of the paintwork with
unsuitable materials
Rfrequent use of automatic car washes
Rwashing the vehicle in direct sunlight
!Never use paint cleaner, buffing or polishing
products, or gloss preserver, e.g. wax, for the
purpose of paintwork care. These products
are only suitable for high-gloss surfaces. Their
use on vehicles with matte paintwork leads to considerable surface damage or, more spe-
cifically, to shiny, spotted areas.
Always have paintwork repairs carried out at a
qualified specialist workshop.
!Do not use wash programs with a hot wax
treatment under any circumstances.
Observe these notes if your vehicle has a clear
matte finish. This will help you to avoid damage to the paintwork due to incorrect treatment.
