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).
In certain driving conditions, such as driving in mountainous areas or hot
weather, there is a risk of the engine or transmission overheating, especially when
carrying heavy loads...
If the start battery is discharged, current from another battery can be used
to start the vehicle.
