Volkswagen Touran Owners Manual: Engine pre-heating

Fig. 128 The front left-hand side of the bumper: cover ① and connecting socket ② for engine pre-heating

First read and observe the introductory information and safety warnings 

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.

Connecting the engine pre-heating system

• Only use those cables included in the scope of delivery.

• All cables and connections must be free of damage  .

• Open the cover  .

• Insert the connecting cable in the socket  .

• Connect the connecting cable with the mains cable.

• Connect the mains cable with a 230-volt socket or 115-volt socket which is earthed and equipped with a residual current circuit breaker.

• Before starting the engine, always remove the connecting cable and close the cover  .

WARNING

Incorrect use of the engine pre-heating system could cause short-circuits, electric shocks, fire or severe or even fatal injuries.

• Connect the mains cable with a 230-volt socket or 115-volt socket which is earthed and equipped with a residual current circuit breaker, which is protected against water, moisture and other liquids.

• Never connect the engine pre-heating system to any other socket, irrespective of whether it is protected or not.

WARNING

The use of unsuitable or damaged sockets and mains cables and failure to keep to general safety procedures can lead to short circuits, accidents, injuries or potentially fatal electric shocks.

• Never use damaged sockets or main cables. Check connections and cables for damage before use.

• Never undertake modifications or repairs of the electrical components.

• Protect electrical connectors from water, moisture and other liquids.

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.
