Checking and filling engine oil
Viewing oil level in the center display
Oil level graphic in the center display
The oil level can be viewed using the electronic oil level gauge in the center display once the vehicle has been started.
- Open the Car Status app from App view in the center display.
- Tap Status to display the oil level.
The system cannot directly detect changes when the oil is filled or drained. The vehicle must have been driven approximately 30 km (20 miles) and have been stationary 5 minutes on a level surface and with the engine off before the correct oil level will be displayed.
If the conditions for measuring oil level are not properly fulfilled (time after engine shutdown, vehicle inclination, ambient temperature, etc.) the message No value availablewill be shown in the center display. This does not mean that anything is wrong in the vehicle systems.
Filling engine oil
Filler pipe
It may be necessary to top up engine oil between regularly scheduled services.
No action is necessary with regard to engine oil level until a message appears in the instrument panel.
If this symbol is shown along with the message Engine oil levelService required, contact Polestar Customer Support. The oil level may be too high.
If this symbol is shown together with a message about low oil level, for example Engine oil level lowRefill 1 liter, fill only with the indicated volume, e.g. 1 liter (1 quart).
Do not spill oil on the hot exhaust pipes as this could cause a fire.
If the engine oil is not checked regularly and the level becomes too low, this could cause serious engine damage.
Coolant
To avoid deterioration of the cooling system, engine trouble, etc., only approved Polestar coolant should be used.
Recommended grade: Polestar-approved premixed coolant. If concentrated coolant is used, mix with 50% water of acceptable quality (i.e. not salt water, etc.). Contact Polestar Customer Support if you are uncertain.
Contact Polestar Customer Support as soon as possible in the event of a warning for too-low or too-high coolant level.
Coolant is hazardous if ingested and could cause damage to organs (kidneys). The product contains ethylene glycol, inhibitor, emetic, water, etc.

Polestar recommends:
The decals shown in the Manual do not claim to be exact reproductions of those found in the vehicle. The purpose is to show approximately how they look and about where they are located on the vehicle. The information that applies for your vehicle in particular is found on the decal on the vehicle.
- If the engine oil is not checked regularly and the level becomes too low, this could cause serious engine damage.
- For the recommended service intervals to apply, an approved engine oil must be used. Only use the prescribed oil grade to top off or change the oil. Otherwise, there is a risk of the vehicle’s service life, startability, fuel consumption and environmental impact being affected.
- Failure to use engine oil of the prescribed grade and viscosity could cause damage to engine-related components. Polestar disclaims warranty liability for such type of damage.
To meet the engine’s service schedule requirements, all engines are filled at the factory with a specially designed synthetic engine oil. The oil has been chosen with great care, taking into account useful life, start performance, fuel consumption and environmental impact.
Change the engine oil and oil filter according to the schedule specified in the Status and Warranty booklet. Oils of a higher grade than that specified may be used. If the vehicle is driven in adverse conditions, Polestar recommends using an oil with a higher grade than that specified.
Polestar recommends contacting Polestar Customer Support for oil changes.
Symbols for low oil level
Polestar uses different systems to warn if the oil level is too low/high or the oil pressure is low. For oil pressure sensors, a warning symbol is displayed in the instrument panel when oil pressure is low

Opening and closing the hood
Opening the hood
| Pull the handle to the left of the brake pedal to release the hood from its fully closed position. |
| Turn the handle under the front edge of the hood counterclockwise to release the catch and lift the hood. |
Warning – hood not closed
When the hood is released, a warning symbol and graphic will be displayed in the instrument panel and an audible signal will sound. If the vehicle begins to roll, the audible signal will be repeated several times.
Contact Polestar Customer Support if the warning symbol is illuminated or the warning signal sounds even if the hood is properly closed.
Closing the hood
- Press down the hood until it begins to close under its own weight.
- When the hood reaches the catch at the handle in the front edge of the vehicle, press down on the hood to close it completely.
Risk of injury! When closing, make sure that the hood is completely unobstructed and that no one can be injured.
Make sure the hood locks securely after closing. It must audibly lock on both sides.
Hood not completely closed.
Hood completely closed.
Never drive with the hood open!
If this symbol appears, or anything else indicates that the hood is not completely closed while driving, stop immediately and close it properly.
Refilling coolant
Location of coolant expansion tank
If there is coolant under the vehicle, smoke from the cooling system, or if more than 2 liters (about 2 quarts) of coolant has been added to the system, there could be something wrong with the cooling system and starting the vehicle could damage the engine. Call a tow truck and do not attempt to start the engine.
When refilling coolant, follow the instructions on the package. Never fill the cooling system with only water. The risk of freezing is increased with too low or too high amounts of coolant.
The coolant may be very hot. Never unscrew the cap when the coolant is hot. If coolant must be filled, unscrew the expansion tank cap slowly to relieve overpressure.
- Unscrew the cover in the plastic covering.
- Unscrew the expansion tank cap and fill coolant as needed. The level should not exceed the yellow MAX mark inside the expansion tank.
Put the components back in place in the reverse order.
- Do not ingest the contents. May cause damage to organs (kidneys).
- Use premixed coolant according to Polestar’s recommendations. If concentrated coolant is used, make sure that the coolant mixture is 50% coolant and 50% water of acceptable quality.
- Do not mix different types of coolant.
- To help ensure sufficient corrosion protection in the system, only use new coolant when replacing larger components in the cooling system.
- Never run the engine unless the cooling system is properly filled. An improperly filled cooling system could lead to high temperatures and cracks in the cylinder heads.
- High levels of chlorine, chlorides and other salts may cause corrosion in the cooling system.
