Volvo XC90: Starting and driving / Battery drain

The electrical functions in the vehicle drain the battery to varying degrees. Avoid using ignition mode II when the engine is switched off. Use ignition mode I instead, as this uses less electrical current.

Note that certain accessories may also drain power from the electrical system. Do not use functions that use a lot of electrical current when the engine is turned off. Examples of such functions are:

  • blower
  • headlights
  • windshield wipers
  • audio system (especially at high volume).

If the starter battery voltage is low, a message is shown in the driver display. The vehicle's energy-saving function will then turn off or reduce certain functions, such as the blower and/or the audio system.

  • To charge the battery, start the engine and let it run for at least 15 minutes (driving charges the battery faster than letting the engine idle).
