208Vehicle careCaution
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.
On vehicles with emblem touchpad:
when cleaning with a high-pressure
jet cleaner ensure a minimum
distance of 30 cm when working
around the tailgate to prevent
unintended unlocking.
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.
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 painted parts of the vehicle
regularly (at the latest when water no longer beads). Otherwise, the
paintwork will dry out.
The foldable sunroof must not be
polished or waxed. When using
automatic car washes, select a
programme without wax additives.
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 waxprogrammes in automatic car washes
if the vehicle is equipped with these
parts.
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.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.
Clean smearing wiper blades with a
soft cloth and window cleaner.
