Volvo XC90: Maintenance and service / Putting the wiper blades in service position
The windshield wiper blades must be in the service (vertical) position for certain
operations, e.g. replacing the blades.

Windshield wipers in the service position.
The windshield wipers must be in the service position when replacing, washing
or lifting the blades (e.g. to scrape ice or snow from the windshield).
CAUTION
Before placing the wipers in service position, ensure that they have not
frozen to the windshield.
Activating/deactivating service position
The service position can be activated/deactivated when the vehicle is stationary
and the windshield wipers are switched off. Service position is activated/deactivated
via Function view in the center display:
Tap the Wiper Service Position
button. The indicator light in the button will illuminate when service position
is activated. The wipers will move to the service position when activated. To deactivate
the service position, tap Wiper Service Position once. The indicator light
in the button will go out when service position is deactivated.
The wiper blades will also move out of the service position if:
- The windshield wipers are turned on.
- The windshield washers are turned on.
- The rain sensor is activated.
- The vehicle begins moving.
CAUTION
If the wiper arms in service position are raised from the windshield, they
must be folded back against the windscreen before activating wiping, washing or
rain sensor as well as before departure. This is to prevent scratching the paint
on the hood.
The wiper blades help remove water from the windshield and rear window. Along
with the washer fluid, they are designed to clean the glass and help improve visibility
while driving...
Washer fluid is used to keep the headlights, windshield and rear window clean.
Washer fluid containing anti-freeze should be used in very cold weather (below-freezing
temperatures)...
