7.3 Ventilation
Condensation Ensure that there is a continuous exchange of air by providing frequent and
efficient ventilation. This is the only method for ensuring that condensation is
not formed during cool weather. During the colder season, a pleasant living cli-
mate is created if heating output, air distribution and ventilation are synchro-
nized. To avoid draft close the air outlet nozzles on the dashboard and set the
air distribution of the base vehicle to air circulation. If the vehicle is laid up for
a longer period, occasionally ventilate it well, especially in summer as heat
accumulation can occur.
7.4 Windows
The oxygen in the vehicle interior is used up by breathing and the use of
gas operated appliances. That is why the oxygen needs to be replaced
on a constant basis. For this purpose, forced ventilation options (e.g.
skylights with forced ventilation, mushroom-shaped vents or floor vents)
are fitted to the vehicle. Never cover or block forced ventilations from the
inside or outside with objects such as e.g. a winter mat. Keep forced ven-
tilations clear of snow and leaves. There is a danger of suffocation due
to increased CO
2
levels.
Although sufficient ventilation is provided, in certain weather conditions,
condensation can form on metal objects (e.g. screwed connections in the
floor).
Additional cold spots can occur at thermal "bridges" (e.g. mushroom-
shaped vents, skylight edges, sockets, filler necks, flaps, etc.).
The windows are fitted with a blind or Roman shade and with an insect
screen or folding insect screen. After the latch has been released, the blind
and insect screen automatically spring back to the initial position by tensile
force. In order not to damage the tension mechanics, hold onto the blind or
insect screen and allow it to slowly return to the initial position. The Roman
shade and folding insect screen are made of thin woven fabric. In order not
to damage the Roman shade or the insect screen, grasp the respective
handle and carefully return it to the initial position.
Do not keep blinds closed over a longer period of time as that can cause
increased material wear.
If the blind or the Roman shade is completely closed, exposure to direct
sunlight can cause heat to accumulate between the blind/the Roman shade
and the glass window. The window could be damaged. For that reason,
close the blind/Roman shade only 2/3 of the way in direct sunlight.
Before commencing the journey, close the windows.
Depending on the weather, close the windows far enough to prevent mois-
ture from entering.
To open and close the hinged window, open or close all catch levers which
are fitted to the hinged window.
When leaving the vehicle, always close the windows.
In extreme weather conditions or if the temperature fluctuates strongly, a
light condensation film can form on the double-glazed acrylic glass. The
glass is designed in such a way that condensation can evaporate when the
external temperature increases. There is no danger of the double-glazed
acrylic glass being damaged by condensation.
