230 Self-help, vehicle care
Windows
Use a soft lint-free cloth or chamois leather
together with window cleaner and insect
remover.
When cleaning the rear window, make sure
the heating element inside the window is
not damaged.
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.
Sun roof 3
Never clean with solvents or abrasives,
fuels, aggressive agents (e.g. paintwork
cleaner, solutions containing acetone,
etc.), acidic or strongly alkaline agents or
scourers.
No stickers may be applied to the sun roof.
Locks
The locks are lubricated with a high-quality
locking cylinder grease in the factory. Only
use de-icer in urgent cases, since it has a
de-greasing effect and affects the
operation of the locks. Have the locks re-
greased in a workshop after using de-icer.
Engine compartment
Clean painted surfaces in the engine
compartment like any other painted
surface.
It is advisable to wash the engine
compartment before and after winter and
preserve it with wax. Cover alternator and
brake fluid reservoir with plastic sheets
before washing the engine.
When washing the engine with a steam-jet
cleaner, do not direct the steam jet at
components of the anti-lock brake system,
the air conditioning system, the climate
control system, belt drive or the fuse box.
After an engine wash, have all engine room
components preserved thoroughly by a
workshop using protective wax.
Do not use high-pressure jet cleaners.
Underbody
Some areas of the vehicle underbody have
a PVC undercoating while other critical
areas have a durable protective wax
coating.
After the underbody is washed, check the
underbody and have more protective wax
applied if necessary.
Bitumen/rubber materials could damage
the PVC coating. Have underbody work
carried out by a workshop.
Before and after winter, wash the
underbody and have the protective wax
coating checked.
Towing equipment
Do not clean the coupling ball bar with a
steam-jet or high-pressure jet cleaner.
