Setting the switch clock (auxiliary warm-air heater)
DANGER Risk of fatal injury due to poisonous exhaust gases
If the tailpipe is blocked or sufficient ventilation is not possible, poisonous exhaust gases such as carbon monoxide may enter the vehicle. 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 extraction 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 running.
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 fire due to hot stationary 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 flammable materials.
the exhaust gas can flow out of the stationary heater exhaust pipe unhindered.
the exhaust gas does not come into contact with flammable materials.
NOTE Damage to the auxiliary heating due to overheating
If the flow of hot air is blocked, the auxiliary heating may overheat and switch off.
Do not block the flow of hot air.
NOTE Battery discharge caused by stationary heater or stationary ventilation operation
Operating the stationary heater or stationary ventilation drains the battery.
After heating or ventilating the vehicle twice, drive for a longer period of time.
