12 V battery

The 12 V battery powers the car's primary electrical system, which includes most of the electrical equipment. However, the high voltage battery is used for driving.

The battery is dimensioned to power the electrical system and functions that are specific to the car model. Under normal conditions, it is kept charged by the larger high voltage battery.


PS2-2007-12V-battery location


If the 12 V battery is disconnected, the automatic opening and closing function must be reset to work properly. A reset must take place for pinch protection to work.


  • The battery can generate oxyhydrogen gas, which is highly explosive. A spark can be formed if a jump lead is connected incorrectly, and this can be enough for the battery to explode.
  • The battery contains sulphuric acid, which can cause serious burns.
  • If sulphuric acid comes into contact with eyes, skin or clothing, flush with large quantities of water. If acid splashes into the eyes - seek medical attention immediately.
  • Never smoke near the battery.
