If the tyre-pressure warning has come on in your Polestar 2 (2021–2024) after you’ve adjusted the pressures or changed a wheel, you store the new pressures from the central touchscreen. It is a normal request from the car — not a fault — and it clears in under a minute once the tyres are set correctly. Here’s how.
How the System Works on the Polestar 2
The Polestar 2 monitors tyre pressure and displays it through the central Android-based touchscreen rather than a separate button on the dash. When you correct the pressures, the car does not automatically assume the new figures are the target — you tell it what “correct” is by storing the pressures, so the system uses them as the baseline it watches against. That is why the warning can linger even after you’ve inflated the tyres properly: the car is still comparing against the old stored values until you re-store.
Before You Start
- Check pressures when the tyres are cold — parked for a few hours or driven less than a couple of miles.
- Use the figure on the driver’s door-pillar label (it may differ front to rear, and for a laden or high-speed load).
- Set all four tyres, and check the spare or repair kit is in order if fitted.
- Have the car parked and stationary before you open the menu.
When to Reset
- After checking or adjusting the tyre pressures.
- After changing one or more wheels or tyres.
Storing the New Pressures
- Turn the EV power switch OFF and adjust all four tyres to the correct cold pressures.
- Turn the EV power switch ON.
- On the touchscreen, open the menu and select ‘More’ > ‘Car status’ > ‘Store tyre pressures’.
- Repeat if necessary — the system now uses the corrected pressures as the baseline.
If the Warning Stays On
- Recheck every tyre — one corner below spec keeps the warning on even if the other three are perfect.
- Re-run ‘Store tyre pressures’ after you’ve set them; storing before they’re right just saves the wrong baseline.
- Cold-morning drop — pressures fall roughly 1 psi for every 10°C, so a sharp overnight chill can trip the light; top up and re-store.
- After a wheel swap the pressures must be re-stored even if the readings look correct.
- Suspect a slow puncture if one tyre repeatedly reads low — have it inspected rather than just re-storing.
- Still showing with correct pressures? A sensor may have a flat battery — look up the code on autodtcs.com.
What to Expect After
Once you’ve stored the pressures the warning should clear straight away, and the touchscreen tyre readout will show the corrected values. The system then monitors quietly in the background for the rest of the trip; you should not see the warning again unless a tyre genuinely drops or you change a wheel.
Frequently Asked Questions
How do I reset the tyre pressure light on a Polestar 2?
Set all four pressures cold to the door-pillar figures, switch the car on, then on the touchscreen choose More > Car status > Store tyre pressures. That saves the corrected pressures as the new baseline and clears the warning. If it stays on, one tyre is probably still low.
Is there a physical reset button?
No — the Polestar 2 has no separate TPMS button. Everything is done from the central display, under More > Car status. This keeps the dashboard clean but means you need the car switched on and stationary to reach the store option.
Do I need a tool?
No for a normal reset — storing the pressures from the screen is all it takes. A workshop tool is only needed if a pressure sensor is replaced, because a new sensor has to be matched to the car before the system will read it.
Does adjusting one tyre need a full reset?
Set all four correctly first, then store the pressures so the baseline is right. If you inflate just one tyre and store, the other three become the reference too — so it’s always worth checking every corner before you save.
Why does the warning come back on cold mornings?
Air contracts as it cools, so pressures naturally fall overnight and can dip below the threshold. Once you drive and the tyres warm up the reading rises again. If it keeps happening, set the tyres slightly toward the upper end of the recommended range when cold and re-store.
Can I keep driving with the warning on?
Treat it as a prompt to check your tyres at the next safe opportunity. If the car also flags a rapid pressure loss, reduce speed and inspect for a puncture. A steady warning after correct inflation usually just needs the pressures re-stored.
If the warning came on alongside other alerts, decode the code on autodtcs.com.
