You can also use the socket 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.
115 V socket
GWarning!
The 115V AC socket operates at high voltage.
Use the 115V AC socket in the vehicle with
the same caution and prudence that you
