The sockets can be used for accessories with amaximum draw of 180 W (15 A). Accessoriesinclude such items as chargers for mobilephones.
If you use the sockets for long periods when theengine 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 thereis sufficient power to start the engine.
