Vehicles with R1234yf refrigerant
WARNING
The air conditioning system contains the refrigerant R1234yf under pressure. In accordance with SAE J2845 (Technician Training for Safe Service and Containment of Refrigerants Used in Mobile A/C System), service and repairs to the refrigerant system may only be performed by trained and certified technicians in order to ensure the safety of the system.
Compressor oil
| Volume | Prescribed grade |
| 100 ml (3.38 fl. oz.) | PAG SP-A2 |
Evaporator
Never repair or replace the A/C system’s evaporator with a previously used evaporator. New evaporators must be certified and labeled in accordance with SAE J2842.
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: Polestar Original or similar fluid that meets 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.
Engine oil specifications
Engine oil of type VCC RBS0-2AE 0W-20 must be used. Lower oil grades may not offer the same fuel economy, engine performance, or engine protection.
Polestar recommends:
General
See the Status and Warranty booklet for information about oil change intervals.
NOTE
This vehicle is delivered from the factory with synthetic oil.
Do not use oil additives.
Oil viscosity
The wrong oil viscosity can shorten engine service life during normal use. VCC RBS0-2AE 0W-20 provides good fuel economy and engine protection. See the viscosity chart.
Oil volume
| The oil volume for the engine is: |
| Liter (approx) | 5.6 |
| US qts (approx) | 5.9 |
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 Washer fluid level is low, refill and 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:
The washer fluid reservoir has a volume of 5 liters (5.3 qts).
Fuel tank volume
The fuel tank’s refillable volume is shown in the table below.
| Liter (approx) | 60 |
| US gallons (approx) | 15.9 |
Transmission fluid specifications
Under normal driving conditions, the transmission fluid will not need to be changed during the transmission’s service life. However, it may need to be changed if the vehicle is driven frequently in adverse driving conditions.
Automatic transmission
| Prescribed transmission fluid: | AW-1 |
