IMPORTANT

The A/C system evaporator must never be repaired or replaced with a previously used evaporator. The new evaporator must be certified and labeled in accordance with SAE J2842.

Brake fluid specifications

The medium in the hydraulic brake system is called brake fluid and is used to transfer braking force from e.g. pressure on the brake pedal via a master brake cylinder to one or more slave cylinders, which in turn act on a mechanical brake.

Recommended grade: Brake fluid meeting a combination of Dot 4, 5.1 and ISO 4925 class 6.

NOTE

Changing or filling brake fluid should be entrusted to an authorized workshop.

Filling washer fluid

Washer fluid is used to help keep the headlights and windshield clean. Washer fluid containing anti-freeze should be used in very cold weather (below-freezing temperatures).

Fill washer fluid into the reservoir with the blue cover. The reservoir is used for both the windshield washer and the headlight washer*.

NOTE

When there is approximately 1 liter (1 qt) of washer fluid remaining, the message Refill washer fluid, level lowand the  symbol will be displayed in the instrument panel.

Recommended grade: Washer fluid recommended by Polestar, with frost protection during cold weather and temperatures below the freezing point.

IMPORTANT

Use washer fluid with the recommended pH value between 6 and 8, diluted as recommended, e.g. in a 1:1 solution with pH-neutral water.

IMPORTANT

Use washer fluid with anti-freeze when temperatures are below the freezing point to help keep the pump, reservoir and hoses from freezing.

Volume:

• Vehicles with headlight washers: 5.5 liters (5.8 qts).
• Vehicles without headlight washers: 3.5 liters (3.7 qts).
