First read and observe the introductory information and safety warnings

In engine preheating mode, the engine coolant is heated slowly using a heating element while the vehicle is stationary. To do so, the cables supplied with the vehicle must be connected to a 230-volt socket or a 115-volt socket, e.g. in a garage. The engine will reach its operating temperature much more quickly if the vehicle is switched on when the coolant has been preheated. This reduces fuel consumption and exhaust emissions during the warm-up phase.

Preheating the engine can take up to 3 hours depending on the outside temperature   .

Connecting the engine preheating system

WARNING

Incorrect use of the engine preheating system can cause short circuits, electric shocks, fire, or severe and fatal injuries.

WARNING

The use of unsuitable or damaged sockets and mains cables, and failure to adhere to general safety procedures, can lead to short circuits, accidents, severe injuries and death.

It is sufficient to test the residual current circuit breaker once a month if the engine preheating system is only used occasionally. If it is used regularly, have it checked once a week.
