12 V sockets
General notes X
Turn the Sm artKey to position G in the ign i-
tion lock ( Y
page 132).
The sockets can be used for accessories wit h a
maximum draw of 180 W (15 A). Accessories
inc lude such items as chargers for mob ile
phones.
If you use the sockets for long per iods when the
engine is swit ched off, the battery may dis-
charge.
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 sock-
ets is automatically cut. This ensures that there
is suff icie nt power to start the engine.
If you have connected a device to the 12 V
socket, leave the cover of the stowage com-
partment open. This prevents the cover from
