Do not use cleaners which contain solvents.
11.3 Upkeep Cleaning the exterior
The vehicle should not be washed more often than necessary.
Only wash the vehicle at specially designated wash
sites.
Use cleaning solvents as sparingly as possible.
Aggressive cleaners such as rim cleaner pollute our
environment.
In some weather conditions even if you ventilate cor-
rectly condensation may settle on cold objects (e.g.
metal ttings or xings).
Thermal bridges (cold/warm) may occur at external
openings (e.g. mushroom fans, roof bonnet edges,
plug sockets, windows, ller pipes, aps, etc.).
Always wipe away condensation immediately.
The relatively small room volume in recreational vehicles; the carrying
in of damp clothing; breathing and perspiration as well as the operati-
on of gas-fuelled devices can increase the formation of condensation.
In order to avoid damage caused by condensation you
should thus – as described above – ensure that there
is a sucient exchange of air. You should also ensure
that any ventilation slots/openings in overhead stowa-
ge compartments and / or in the stowage areas in se-
ating and sleeping areas are not obstructed.
This is the only way to prevent condensation and, as a result, mould
forming in unfavourable weather conditions. When heating, air dis-
tribution and ventilation are all coordinated with one another it is
possible to achieve a pleasant room climate at any time of the year.
Do not make any alterations to the standard hot-air system. Do not
turn o the system’s circulation fans in the winter months, even at
night.
Make sure that vehicle is occasionally ventilated even when it is not
moved for some time; in summer there is a risk of heat accumulation.
When ventilating be sure to also ventilate the externally accessible
stowage areas as well as the interior space. Even if the vehicle is
parked in a closed room (e.g. a garage) you must still ventilate it
regularly.
