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 antifreeze. 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 instrument panel.
Volume:
- Models with headlight washers: 5.8 qts (5.5 liters).
- Models without headlight washers: 3.7 qts (3.5 liter).
