290 Self-help, vehicle care
Clean edges and folds on opened doors
and flaps as well as the areas they cover.
Thoroughly rinse off and leather-off the
vehicle. Rinse leather frequently. Use
separate leathers for paint and window
surfaces: remnants of wax on the windows
will impair vision.
Observe national regulations.
Waxing
Wax your vehicle regularly, in particular
after it has been washed using shampoo
and at the latest when water no longer
forms beads on the paintwork, otherwise
the paintwork will dry out.
Also wax edges and folds on opened doors
and flaps as well as the areas they cover.
Polishing
Polishing is necessary only if the paint has
become dull or if solid deposits have
become attached to it.
Paintwork polish with silicone forms a
protective film, making waxing
unnecessary.
Plastic body parts should not be treated
with wax and polish.
Use Metallic Paintwork Wax on vehicles
with a metallic-effect paint finish.
Sunroof 3
Never clean with solvents or abrasive
agents, fuels, aggressive media (e.g. paint
cleaner, acetone-containing solutions etc.),
acidic or highly alkaline media or abrasive
pads.
No stickers may be applied to the sunroof.
Wheels
Use a pH-neutral wheel cleaning agent to
clean the wheels.
Wheels are painted and can be treated
with the same agents as the body. For alloy
wheels we recommend use of Alloy Wheel
Preserver.
Paintwork damage
Repair minor paintwork damage such as
stone chips, scratches etc. immediately
using the touch-up pen or spray before rust
forms. If rust has already formed, have a
workshop eliminate the cause. Also check
the surfaces and edges facing the road
surface on which rust may have developed
unnoticed for some time.
Exterior lights
Headlight and other protective light bezels
are made of plastic. If they require
additional cleaning after the vehicle has
been washed, clean them with Car
Shampoo. Do not use any abrasive or
caustic agents, do not use an ice scraper,
and do not clean them dry.
