218Vehicle careIf using a vehicle wash, comply with
the vehicle wash manufacturer's
instructions. The windscreen wipers must be switched off and the exterior
mirrors must be folded in. Remove
antenna and external accessories
such as roof racks etc.
If you wash your vehicle by hand,
make sure that the insides of the
wheel housings are also thoroughly
rinsed out.
Clean edges and folds on opened
doors and the bonnet as well as the
areas they cover.
Clean bright metal mouldings with a
cleaning solution approved for
aluminium to avoid damages.Caution
Always use a cleaning agent with
a pH value of four to nine.
Do not use cleaning agents on hot surfaces.
Have the door hinges of all doors
greased by a workshop.
Do not clean the engine compartment with a steam-jet or high-pressure jet
cleaner.
Thoroughly rinse and leather-off the vehicle. Rinse leather frequently. Use
separate leathers for painted and
glass surfaces: remnants of wax on
the windows will impair vision.
Do not use hard objects to remove
spots of tar. Use tar removal spray on
painted surfaces.
Exterior lights
Headlight and other light covers are
made of plastic. Do not use any
abrasive or caustic agents, do not use an ice scraper, and do not clean them
dry.
Polishing and waxing
Wax the vehicle regularly (at the
latest when water no longer beads).
Otherwise, the paintwork will dry out.
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.
Unpainted plastic body parts must not be treated with wax or polishing
agents.
Matt filmed body parts or decor tapes must not be polished, to avoid
gleaming. Do not use hot wax
programmes in automatic car washes if the vehicle is equipped with theseparts.
Matt painted decor parts, e.g. mirror
housing cover, must not be polished.
Otherwise these parts would become
agleam or the colour would be
dissolved.
Windows and windscreen wiper
blades
Use a soft lint-free cloth or chamois
leather together with window cleaner and insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
