Overload - starter battery
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
- windscreen wiper
- audio system (high volume).
If the battery voltage is low the 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.
