Topping up the washer fluid

Washer fluid is used for cleaning the windscreen. Washer fluid with antifreeze must be used when the temperature is under the freezing point.
PS2-23w17-Washer fluid refill

Washer fluid is filled into the reservoir with the blue cap. The reservoir has a volume of 3.5 litres (3.7 qts).


When approx. 1 litre (1 qt) of washer fluid remains in the reservoir, the message Refill washer fluid, level low is shown in the driver display, together with the PS-1926-Washer fluid symbol symbol.

Prescribed grade: Washer fluid recommended by Polestar – with frost protection during cold weather and for temperatures below freezing point.


Use washer fluid with a recommended pH of between 6 and 8, in working dilution (e.g. 1:1 with neutral water).


Use washer fluid with antifreeze when the temperature is below freezing to avoid the fluid freezing inside the pump, reservoir and hoses.
