Stationary heater/ventilation

▌Stationary heater/ventilation function

The following function is equipment-depend-

▌Switching the stationary heater/ventilation

on/o via the operating unit

DANGER Risk of fatal injury due to poison-

ous exhaust gases

If the tailpipe is blocked or sucient 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 o 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.

WARNING Risk of re 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

contact with ammable materials.

the exhaust gas can ow out of the

stationary heater exhaust pipe unhin-

dered.

the exhaust gas does not come into

contact with ammable materials.
