Maintenance and care
Z

!Lock the car if you wash it in an automatic
car wash. Otherwise, the vehicle might be
damaged.
!Never clean your vehicle in aTouchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
If you have your vehicle cleaned in ahigh-
pressure automatic car wash, small amounts
of water may enter the vehicle.
!Make sure that the automatic transmission
is in position Nwhen washing your vehicle in
at ow-through car wash. The vehicle could be
damagedift he transmission is in another
position.
!Make sure that:
Rthe side windows and the roof are com-
pletely closed
Rthe climate control blower is switched off
Rthe windshieldw iper switch is at position 0
The vehicle could otherwise be damaged.
You can clean the vehicle at an automatic car
wash from the very start.
Preferably clean the vehicle at automatic car
washes that use textile washing elements with-
out brushes. This prevents fine scratches from
forming on the paintwork and film.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
After using an automatic car wash, wipe off wax
from the windshielda nd the wiper blades. This
will prevent smears and reduce wiping noises
caused by residue on the windshield.
iVehicles with decorative film: select awash
program without hot wax at the automatic car
wash.
Washing by hand
In some countries, washing by hand is only
allowed at speciallye quipped washing bays.
Observe the legal requirements in each country.
XDo not use hot water and do not wash the
vehicle in direct sunlight.
XUse asoft sponge to clean.
XUse amild cleaning agent, such as acar
shampoo approved by Mercedes-Benz.
XThoroughly hose down the vehicle with agen-
tle jet of water.
XDo not point the water jet directly towards the
air inlet or the edges of decorative foils.
XUse plenty of water and rinse out the sponge
frequently.
XRinse the vehicle with clean water and dry
thoroughly with achamois.
XDo not let the cleaning agent dry on the paint-
work or the decorative foils.
Carefully remove all deposits of road salt as
soon as possible when driving in winter.
Powerw ashers
GWARNING
The water jet from acircular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nentsd amagedint his way may fail unexpect-
edly.T here is arisk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis componentsr eplaced imme-
diately.
!Vehicles with decorative foil: parts of your
vehicle are covered with decorative foil. Main-
tain adistance of at least 27.5 in (70 cm)
between the foil-wrappedp arts of the vehicle
and the nozzle of the high pressure cleaner.
Information aboutt he correct distance is
available from the equipment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
The water temperature of the high-pressure
cleaner must not exceed 140 °F (60 °C).
!Alwaysm aintainadistance of at least
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information aboutt he
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, roof gaps, joints, etc.
Relectrical components
Rbattery
Rplug-type couplings
Rlights

Rseals
Rtrim
Rventilation slots
Damaged seals or electrical componentsc an
lead to leaks or failures.
!Do not use high-pressure cleaners if the
tank recess is open while you clean it. This
can cause damage to the seals or other com-
ponents.
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 aqualified specialist workshop.
XRemove dirt immediately,w here 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.T his is the
case approximately every three to five months,
depending on the climate conditions and the
care product used.
If dirt has penetrated the paint surface or if the
paint has become dull,t he paint cleaner recom-
mended and approved by Mercedes-Benz
should be used.
Do not use these care products in the sun or on
the hood while the hood is hot.
XUse asuitable touch-up stick, e.g. MB Touch-
Up Stick,tor epair slight damage to the paint-
work quickly and provisionally.
Mattef inish care
!Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to shine.
!The following can give the paint aglossy
appearance and thus reduce the matt effect:
RRubbing hard with unsuitable agents
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,tos hiny, spotted areas.
Always have paintwork repairs carried out at a
qualified specialist workshop.
!Only use automatic car washes which cor-
respond to the latest technological stand-
ards. Never use wash programs which finish
by treating the vehicle with hot wax.
Observe these notes if your vehicle has aclear
matte finish. This will help you to avoid damage
to the paintwork due to incorrect treatment.
These notes also apply to light alloy wheels with
ac lear matte finish.
iUse only insect remover and car shampoo
from the range of recommended and
approved Mercedes-Benz care products.
Cleaning the decorative film
!The following may have an effect on the ser-
vice life and coloring of decorative film:
Rsunlight
Rtemperature, e.g. hot-air fan
Rweather conditions
Rstone impacts and dirt
Rchemical cleaning agents
Rgreasy substances
!Do not use any types of polish on matt dec-
orative film. Polishing surfaces covered with
film gives it ashiny finish.
!Do not treat matt or structured decorative
film with wax. This may lead to marks that
cannot be removed.
240Care
Maintenance and care

The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
Rbe at least 50%. This will protectthe engine
cooling system against freezin gdown to
approximately -35 ‡(-37 †).
Rnot exceed 55% (antifreez eprotection down
to -49 ‡[-45 †]). Otherwise, heat will not be
dissipated as effectively
If the vehicle has lost coolant, add equal
amounts of water and antifreeze/corrosion
inhibitor.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor concentrate in accordance
with MB Specifications for ServiceP roducts
310.1.
iWhen the vehicle is first delivered, it is filled
with acoolant mixture that ensures adequate
antifreeze and anti-corrosion protection.
iThe coolant is checked with every mainte-
nancei nterval at aqualified specialist work-
shop.
