After adjusting the tyre pressures or changing a wheel on your Toyota C-HR Mk2 (2023–present), the tyre-pressure warning may stay lit until you tell the car the new values are correct. You do that by storing the pressures as the reference from the dashboard menu using the steering-wheel controls. A lit TPMS lamp here simply means the current pressures no longer match the stored baseline — it’s a normal prompt, not a fault. Here’s how to clear the tyre-pressure warning.
How It Works on This Model
The C-HR Mk2 monitors the pressures and compares them against a reference set that you store. When you inflate, deflate or move a wheel, the readings drift away from that stored baseline and the warning appears. Running the ‘Set indicated air pressure’ function takes whatever the tyres are at right now — which is why you inflate them correctly first — and saves that as the new reference the system watches from then on.
Set the Pressures First
Park on level ground and inflate all four tyres cold to the figure on the driver’s door-pillar label, then store the reference.
Before You Start
- Set the pressures cold — check them before driving, or at least a couple of hours after, so warm tyres don’t read high.
- Use the door-pillar figure, and match it to the load if the label lists a laden setting.
- Only store once every tyre is right — the car saves whatever it sees, so a low corner set now becomes a low baseline.
- Switch the ignition on (engine can stay off) so the instrument menu is available on the steering-wheel controls.
How to Reset the C-HR Mk2 TPMS
- Turn the ignition on.
- Using the multifunction steering-wheel controls, scroll through the instrument-display menu.
- Select ‘Tyre pressure’.
- Select ‘Set indicated air pressure’ (or ‘Set’).
- The TPMS warning light flashes about 3 times to confirm the system has stored the new pressures.
The light then goes out once the car confirms the readings.
If the Light Stays On
- Re-check every tyre — one low corner keeps the warning on.
- Re-store after any change — the C-HR needs the new baseline set whenever pressures change.
- Give it a short drive after storing so the system settles on the fresh reference.
- Watch a corner that keeps dropping — if one tyre falls again soon after you set it, suspect a slow puncture rather than a menu problem.
- A steady-flashing TPMS light points to a sensor fault (flat sensor battery, or an unmatched sensor after a wheel change) and needs a tyre shop’s tool.
What to Expect After
Once you’ve stored the correct cold pressures, the warning clears and stays off for the trip. It’s normal for the lamp to return after a cold spell or over a few weeks as pressures naturally fall — just top up to the label figure and re-run ‘Set indicated air pressure’ to save the new baseline.
Frequently Asked Questions
How do I reset the tyre pressure light on a Toyota C-HR?
Set the pressures cold to the door-pillar figure, then on the dash menu choose Tyre pressure → Set indicated air pressure. The TPMS light flashes about 3 times to confirm the system has stored the new values, and the warning then clears.
Do I need a tool?
No — the C-HR stores the new reference from its own menu using the steering-wheel controls, so no garage equipment is needed. A tool is only required if a sensor has actually been replaced and has to be matched to the car.
Why does the light come on when it’s cold?
Pressures fall as the temperature drops, so a cold morning can take a tyre below the stored reference even with no leak. Top up to the label figure and re-store the reference, and the light clears. It’s the most common harmless cause of a TPMS warning.
It came on after a wheel change — why?
The reference moved when the pressures changed during the swap. Set all four correctly, then run ‘Set indicated air pressure’ so the new pressures become the baseline the system watches. There’s no need for a tool unless a sensor itself was replaced.
The TPMS light is flashing and won’t stop — what does that mean?
A brief flash when you store the pressures is normal confirmation. A light that keeps flashing at start-up, or flashes then stays on, usually signals a sensor fault — often a flat sensor battery or a sensor that isn’t matched after a wheel change — and needs checking with a tyre shop’s tool.
