Tyre pressure warning light stays on

The light tells you that the system has detected tyre pressure that is too low, or that the system itself has a fault. A tyre that is slowly going flat is one of the most common causes. Pressure that is too low affects grip, stopping distance and wear.

Recognisable signs

What you may notice.

  • A yellow symbol with an exclamation mark in brackets comes on after starting or while driving
  • The light flashes first and then stays on, which sometimes points to a fault in the system
  • One tyre seems softer than the others
  • The light appeared after a cold night or after a tyre change
  • The car pulls or feels different

Possible causes

What may be behind it.

These are possibilities, not a diagnosis. A technician identifies which cause fits your car after checking it.

  1. A punctured or slowly deflating tyre

    A nail, a damaged valve or a leak at the wheel rim can make the pressure drop gradually.

  2. Natural pressure differences

    In cold weather, tyre pressure drops. Sometimes topping up to the recommended pressure is enough, but also check that the pressure stays stable afterwards.

  3. A new set of tyres or a tyre change

    After a change, the system sometimes has to be reset, depending on the car.

  4. A sensor or the system itself

    A sensor in the wheel can be faulty or have a flat battery. The warning may then be wrong, but that has to be checked.

  5. A damaged tyre

    A bulge or crack in the tyre is a safety risk in itself, even if the pressure still seems fine.

Keep driving?

Can I keep driving with this?

If the light is on but the tyres look normal, you can drive carefully to somewhere you can check the pressure. Do not keep driving for long on a tyre that is too soft: it can overheat and be damaged. If a tyre is visibly flat or unsafe, stop and arrange help.
