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.
Jumper cable connecting points. Engine compartment appearance
may vary depending on vehicle model and equipment level...
Other information:
BLIS1 functionality may be reduced in certain situations.
Keep the marked area clean (on both the left and right sides
of the vehicle)2.
Examples of limitations:
Dirt, ice and snow covering the sensors may reduce functionality and prevent
the system from providing warnings...
The low beam bulbs in the halogen headlights can be changed without the help
of a workshop.
Before the bulbs can be replaced, the plastic covering over the headlight must
be removed.
CAUTION
Never touch the bulb glass with your bare fingers. Grease and oils from
your fingers vaporize in the heat and will leave a deposit on the reflector, which
may damage it...
