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  .
- 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.
