Electrical socket

Using 12-volt electrical socket

Electrical accessories can be connected to the 12-volt electrical socket.

Depending on the vehicle equipment, these sockets are located in the passenger’s side footwell, in the glove box and in the oddments tray in the center console.

Connecting charging adapter


  1. The 12-volt electrical socket and thus the connected electrical accessories function even if the ignition is switched off or the vehicle key is removed.
    If the engine is not running and the accessories are switched on, the vehicle battery will be discharged. The power supply is interrupted after about 30 minutes to protect the vehicle battery. If the consumer is to be switched on again, the ignition must be switched on once.
  2. The maximum load capacity of a 12-volt electrical socket or cigarette lighter is 20 A, if only one consumer is being used. Do not exceed 10 A per 12-volt electrical socket or cigarette lighter if several consumers are operating simultaneously.
  3. Unshielded devices and equipment can cause interference to radio and TV reception as well as vehicle electronics.
