The battery may need to be charged in the following cases:

  • If the vehicle is not used for prolonged periods, longer than a month.


Do not connect charging devices to the 12 volt socket in the vehicle

Do not connect battery chargers to the factory- installed 12 volt sockets in the vehicle as this may damage the vehicle battery due to an increased power consumption.

Starting aid terminals In the vehicle, only charge the battery via the starting aid terminals, in the engine compartment with the engine off.
