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. These
products are only suitable for high-gloss sur-
faces. Their use on vehicles with matte finish
leads to considerable surface damage (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.
These notes also apply to light alloy wheels with a clear matte finish.
The vehicle should ideally be washed by hand
using a soft sponge, car shampoo and plenty of
water.
Use only insect remover and car shampoo from
the range of approved Mercedes-Benz care
products.
Cleaning the vehicle parts
Cleaning the wheels
GWARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-
edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
!Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
