What it means
The tyre pressure symbol often looks like a horseshoe or flat tire shape with an exclamation mark. It means the tyre pressure monitoring system has detected low pressure or a sensor issue. Low pressure can reduce grip, increase wear, and cause overheating.
What to do first
- Slow down and avoid sharp steering if the car pulls or feels unstable.
- Check all tyre/tire pressures, including the spare if your vehicle monitors it.
- Inflate to the pressure shown on the door placard or owner's manual, not the number printed on the tyre sidewall.
- Reset the TPMS only after correcting the pressure if your vehicle requires a reset.
Common causes
- One or more tyres/tires are underinflated
- Puncture, nail, or slow leak
- Cold weather pressure drop
- Recent tyre rotation or replacement
- Faulty TPMS sensor or weak sensor battery
When to stop driving
Stop as soon as safe if the tyre looks flat, the car pulls strongly, steering vibrates, or you hear flapping or thumping. Driving on a flat tyre can damage the wheel and make the car harder to control.
Tire Pressure Warning FAQ
Why did the TPMS light come on after cold weather?
Tyre pressure drops as temperature falls. Inflate to the recommended pressure when the tyres are cold.
Why is the light still on after inflating?
Some cars need a TPMS reset or a short drive. If it stays on, a sensor or leak may need inspection.
