ventilation slots
Damaged seals or electrical component sc 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: R
stickers R
films R
magnetic 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 aq ualified specialist workshop.X
Remove dirt immediately ,w here possible,
while avoiding rubbing too hard. X
Soak insect remains with insect remover and
rinse off the treated areas afterwards. X
Soak bird droppings with water and rinse off
the treated areas afterwards. X
Remove coolant, brake fluid, tree resin, oils,
fuels and greases by rubbing gently with a
cloth soaked in petroleum ether or lighter
fluid. X
Use tar remover to remove tar stains. X
Use 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. X
Use as uitable touch-up stick, e.g. MB Touch-
Up Stick ,tor epair slight damage to the paint-
work quickly and provisionally. Matt ef inish care
! Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to shine.
! The following can give the paint ag lossy
appearance and thus reduce the matt effect: R
Rubbing hard with unsuitable agents R
Washing 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 ac lear
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.
i Use 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: R
sunlight R
temperature, e.g. hot-air fan R
weather conditions R
stone impacts and dirt R
chemical cleaning agents R
greasy substances
! Do not use any types of polish on matt dec-
orative film. Polishing surfaces covered with
film gives it as hiny finish.
! Do not treat matt or structured decorative
film with wax. This may lead to marks that
cannot be removed.240
Care
Maintenance and care

Observe the notes in the section on the care and
treatment of matt paintwork ( Y
page 240);
these notes also apply to decorative film.
To clean, use plenty of water and am ild cleaning
agent without additional or abrasive products,
e.g. ac ar shampoo approved by Mercedes-
Benz. X
Remove bird droppings, tree resin or fuel as
soon as possible.
The decorative film may be irreparably dam-
aged. X
Dry vehicles covered with film using as oft,
absorbent cloth after every wash.
Water marks could otherwise form.
Scratches, corrosive deposits, areas affected by
corrosion and damage caused by inadequate
care cannot always be completely repaired. In
such cases, visit aq ualified specialist workshop.
The cleaning product Paint Cleaner, which has
been approved and recommended by
Mercedes-Benz ,s hould be used when dirt has
penetrated the decorative film surface or the
decorative film has become dull.
The manufacturer can provide you with infor-
mation on special care and cleaning products.
Surfaces covered with film may appea rs hinier
after the decorative film has been removed.
i Have work or repairs on decorative film car-
ried out at aq ualified specialist workshop.
Mercedes-Benz recommends that you use an
authorized Mercedes-Benz Center for this
purpose.
Cleaning the vehicl ep arts
Cleaning the wheels
G WARNING
The water jet from ac ircular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nent sd amaged in this way may fail unexpect-
edly .T here is ar isk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis component sr eplaced imme-
diately. ! Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park your vehicle for al ong period of
time directly after cleaning, particularl ya fter
cleaning the wheel rim with wheel cleaner.
Wheel cleaner can lead to the increased cor-
rosion of the brake discs and pads. Therefore,
drive for af ew minutes after cleaning. By
heating up the brakes, the brake discs and
pads dry. The vehicle can then be parked for a
long period of time.
Cleaning the windows
G WARNING
You could become trapped by the windshield
wipers if they start moving while cleaning the
windshiel dorw iper blades. There is ar isk of
injury.
Alway ss witch off the windshiel dw ipers and
the ignition before cleaning the windshiel do r
wiper blades.
! Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the inside of the windows. Do
not touch the insides of the windows with
hard objects, e.g. an ice scraper or ring. There
is otherwise ar isk of damaging the windows.
! Clea nt he water drainage channels of the
windshiel da nd the rear window at regular
intervals. Deposits such as leaves, petals and
pollen may under certain circumstances pre-
vent water from draining away. This can lead
to corrosion damage and damage to elec-
tronic components. X
Clea nt he inside and outside of the windows
with ad amp cloth and ac leaning product that
is recommended and approved by Mercedes-
Benz.

Allow the frozen battery to thaw out before charging it or jump-starting.
! Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter coul db e
damaged by the non-combusted fuel.
If the indicator/warning lamp sdon ot light up at low temperatures, it is very likel yt hat the dis-
charge db attery has frozen. In this case, you may neither charge the battery nor jump-start the
vehicle. The service life of at hawed-out battery may be shorter. The starting characteristics can be
impaired ,p articularl yatl ow temperatures. Have the thawed-out battery checked at aq ualified
specialist workshop.
Do not start the vehicl eu sing ar api dc harging device. If you rv ehicle's battery is discharged, the
engine can be jump-started from another vehicl eorf rom as econd battery using jumper cables.

The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible ,j ump-
start the vehicl eu sing as econd battery or aj ump-starting device.R
You may only jump-start the vehicl ew hen the engine and exhaust system are cold.R
Do not start the engine if the battery is frozen. Let the battery thaw first. R
Only jump-start from batterie sw ith a12Vv oltag er ating.R
Only use jumper cables which have as ufficient cross-section and insulated terminal clamps.R
If the battery is full yd ischarged, leave the battery that is being used to jump-start connected for
af ew minutes before attempting to start. This charge st he battery slightly.R
Make sure that the two vehicles do not touch.
Make sure that: R
The jumper cables are not damaged. R
Bare parts of the terminal clamp do not come into contact with other metal parts while the jumper
cables are connected to the ba ttery.R
