hot, and the child could be burned on these
parts.GWARNING

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

If accessories are connected, make sure
that a maximum current draw of 15 A is not
exceeded. Otherwise, you will overload the
