DANGER Risk of f
atal injury due to poison-
ous exhaust gases
If the tailpipe is blocked or suPcient v
entila-
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 oM in
enclosed spaces wit
hout an air extrac-
tion system, e.g. in garages. 
Keep the tailpipe and the area around

he vehicle free from snow when the
vehicle or the auxiliary heating is run-
ning. 
Open a door or a roof hatch on the wind-
w

ard side of the vehicle to ensure an
adequate supply of fresh air. &
WARNING Risk of Nr
e due to hot station-
ary heater components and exhaust gases
Flammable materials such as leaves, grass or
twigs ma
y ignite. 
When the stationary heater is switched
on, mak

e sure that:
= hot vehicle parts do not come into
contact with Oammable materials.
= the exhaust gas can Oow out of the
stationary heater exhaust pipe unhin-
dered.
= the exhaust gas does not come into
