& 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
engine or the stationary heater is run-
ning.
Open a window on the side of the vehicle
#
facing away from the wind to ensure an
adequate supply of fresh air.
