Important safety notes
G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the
vehicle. This is the case, for example in
enclosed spaces or if the vehicle gets stuck
in snow. There is a risk of fatal injury.
Switch the auxiliary heating off in enclosed
spaces without extraction systems, e.g. in
garages. If the vehicle is stuck in snow and
you have to leave the auxiliary heating run-
ning, keep the exhaust pipe and the area
around the vehicle free of snow. To ensure an
adequate supply of fresh air, open a window
on the side of the vehicle that is not facing
into the wind.
G WARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot, e.g.
the exhaust system. Flammable material such
as leaves, grass or twigs may ignite if they
come into contact with hot parts of the
exhaust system. There is a risk of fire.
When the auxiliary heating is switched on,
make sure that no flammable material can
come into contact with hot vehicle compo-
nents.
! Turn on the auxiliary heating at least once
a month for approximately 10 minutes. The
auxiliary heating could otherwise be dam-
aged.
! Make sure that the flow of hot air is not
blocked. The auxiliary heating will other-
wise overheat and switch off.
Your vehicle may be equipped with either an
auxiliary hot-water heater or an auxiliary
warm-air heater. Adjustment and operation of
the:
hot-water auxiliary heater is done via the
R
on-board computer and with the auxiliary
heating button in the control panel
