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 .
