12 V sockets
General notes X
Turn the SmartKey to position G in the igni-
tion lock ( Y
page 136).
The sockets can be used for accessories with a
maximum draw of 180 W (15 A). Accessories
include such items as chargers for mobile
phones.
If you use the sockets for long periods when the
engine is switched 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 sufficient 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
being blocked.
