Rseals

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.
