Fig. 128 The front left-hand side of the bumper: cover ① and connecting socket ② for engine pre-heating
For the engine pre-heating mode, the engine coolant is heated slowly using a heating element while the vehicle is stationary. For this purpose the cables included in the scope of delivery 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 pre-heated. This reduces fuel consumption and exhaust emissions during the warm-up phase.
The pre-heating of the engine can take up to 3 hours depending on the outside temperature.

WARNING
It is sufficient to test the residual current circuit breaker once a month if the engine pre-heating system is only used occasionally. In case it is used regularly, have it checked once a week.
