agents, fuels, aggressive media
(e.g. paint cleaner, acetone-
containing solutions etc.), acidic or
highly alkaline media or abrasive
pads.
Wheels and tyres Do not use high-pressure jet
cleaners.
Clean rims with a pH-neutral wheel
cleaner.
Rims are painted and can be treated
with the same agents as the body.
Paintwork damage Rectify minor paintwork damage with
a touch-up pen before rust forms.
Have more extensive damage or rust
areas repaired by a workshop.
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 it waxed 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.
Liquid gas system9 Danger
Liquid gas is heavier than air and
can collect in sink points.
Take care when performing work
at the underbody in a pit.
For painting work and when using a
drying booth at a temperature above
60 °C, the liquid gas tank must be
removed.
Do not make any modifications to the
liquid gas system.
Towing equipment
Do not clean the coupling ball bar with
a steam-jet or high-pressure jet
cleaner.
Rear carrier system Clean the rear carrier system with a
steam-jet or high-pressure jet cleaner
at least once a year.
Operate the rear carrier system
periodically if not in regular use, in
particular during winter.
Air shutter Clean the shutter system in the front
bumper to maintain correct
functionality.
