Overload - starter battery

The electrical functions in the car load the starter battery to varying degrees. Avoid using the key position II when the engine is switched off. Instead use position I - which uses less power.

Also, be aware of different accessories that load the electrical system. Do not use functions which use a lot of power when the engine is switched off. Examples of such functions are:

  • ventilation fan
  • headlamps
  • windscreen wiper
  • audio system (high volume).

If the starter battery voltage is low then the combined instrument panel's information display shows the text Low battery charge Power save mode. The energy-saving function then shuts down certain functions or reduces certain functions such as the ventilation fan and/or audio system.

In which case, charge the starter battery by starting the engine and then running it for at least 15 minutes - starter battery charging is more effective during driving than running the engine at idling speed while stationary.
