Points to observe before use
The sockets can be used for accessories, e.g.
lamps or mobile phone chargers with a maximum current draw of 180 W (15 A).
If you use the sockets for long periods when the engine is switched off, the battery may discharge.
Turn the SmartKey to position 1

An emergency cut-out ensures
that the
on-board voltage does not drop too low. If
the on-board voltage is too low, the power
to the sockets is automatically cut. This
ensures that there is sufficient power to
start the engine.
