6.3 Ventilation

The oxygen in the vehicle interior is used up by breathing and the use
of gas operated appliances. That is why the used air must be replaced
permanently. For this purpose, forced ventilation options (e.g. sky-
lights 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 ventilations clear of snow and leaves. There is a danger of suf-
focation 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.).
