DANGER
If the exhaust pipe is blocked or sufficient
ventilation is not possible, toxic exhaust
fumes can enter the vehicle, especially car-
bon monoxide. This is the case, e.g. in
enclosed spaces, or if the vehicle is stuck in
snow. There is a risk of fatal injuries.
You should switch off the auxiliary heating in
enclosed spaces which do not have an extrac-
tion system, e.g. a garage. If the vehicle is
stuck in snow and you must leave the auxiliary
heating running, keep the exhaust pipe and
the area around the vehicle clear of snow. To
guarantee a sufficient supply of fresh air, open
a window on the side of the vehicle away from
the wind.

R
There is a risk of fire.
When the auxiliary heating is switched on,
make sure that:
no flammable materials come into contact
R
with hot vehicle components
the exhaust gas can escape from the
R
exhaust pipe unhindered
the exhaust gas does not come into contact
R
with flammable materials.
The auxiliary heating and the exhaust gas outlet

wheel.
