& DANGER Risk of fatal injury due to poison-
ous exhaust gases
If the tailpipe is blocked or sufficient ventila-
tion is not possible, poisonous exhaust gases
such as carbon monoxide may enter the vehi-
cle. This is the case in enclosed spaces or if
the vehicle gets stuck in snow, for example.
Always switch the stationary heater off in
#
enclosed spaces without an air extrac-
tion system, e.g. in garages.
Keep the tailpipe and the area around
#
the vehicle free from snow when the
vehicle or the auxiliary heating is run-
ning.
Open a door or a roof hatch on the wind-
#
ward side of the vehicle to ensure an
adequate supply of fresh air.
& WARNING Risk of fire due to hot station-
ary heater components and exhaust gases
Flammable materials such as leaves, grass or
twigs may ignite.
When the stationary heater is switched
#
on, make sure that:
hot vehicle parts do not come into
R
contact with flammable materials.
the exhaust gas can flow out of the
R
stationary heater exhaust pipe unhin-
dered.
the exhaust gas does not come into
R
contact with flammable materials.
* NOTE Battery discharge caused by sta-
tionary heater or stationary ventilation
operation
Operating the stationary heater or stationary
ventilation drains the battery.
After heating or ventilating the vehicle
#
