Information about auxiliary heating

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 systems, e.g. in garages.

Keep the tailpipe and the area around the vehicle free from snow when the engine or the stationary heater are running.

Open a window on the windward side of the vehicle 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.

The heater for the auxiliary heating is fitted at the front of the vehicle underbody. The emissions outlet is on the left side of the vehicle below the front door.

WARNING Risk of poisoning during work on the auxiliary warm-air heater

If work on the heat exchanger of the auxiliary warm-air heater is not performed correctly, exhaust fumes could leak into the passenger compartment.

Have all work on the auxiliary warm-air heater carried out at a qualified specialist workshop.

If you are transporting hazardous materials, comply with the relevant safety regulations. Place objects a sufficient distance from the auxiliary heating outlet opening.

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.

Your vehicle may be equipped with either a hot-water auxiliary heater or an auxiliary warm-air heater.

The hot-water auxiliary heater is adjusted and operated using the rocker switch on the climate control system control panel and via the multimedia system or by remote control.

The auxiliary warm-air heater is adjusted and operated via the switch clock on the lower centre console or by remote control
