Refilling the windshield washer fluid
reservoir
Washer fluid helps keep the windshield and
headlights clean.
The windshield and headlight washers
*
share a
common reservoir. Open the blue cap to refill
washer fluid (see the illustration for the location
of the reservoir).
During cold weather, the reservoir should be filled
with windshield washer solvent containing anti-
freeze. Use Volvo Original Washer Fluid or the
equivalent with a recommended pH value
between 6 and 8 in a 1:1 solution.
When there is approx. 1 qt (1 liter) of washer
fluid remaining in the reservoir, a text message
and the
symbol will be displayed in the
