Points to observe before use
The sockets can be used for accessories, e.g. lamps or mobile phone chargers with a maximum current draw of 180 W (15 A).
If you use the sockets for long periods when the engine is switched off, the battery may discharge.
- Turn the SmartKey to position 1 in the ignition lock.
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.
