My Tyre Pressure Warning Light Is On — What Should I Do?

Do not ignore a tyre-pressure monitoring system (TPMS) warning. It may mean that one or more tyres are underinflated, punctured or that the monitoring system has developed a fault.

First: Find Somewhere Safe to Stop

Slow down, avoid sudden braking or steering and stop safely as soon as practical. If a tyre looks flat, is visibly damaged, or the vehicle feels unstable, do not continue driving. Arrange roadside assistance.

What to Check

1

Inspect every tyre

Look for a visibly low or flat tyre, cuts, bulges, exposed cords, objects in the tread or other damage. A visual check alone cannot confirm that the pressures are correct.

2

Check the pressures

Use an accurate pressure gauge and compare every tyre with the vehicle manufacturer’s recommended pressures. Check them when the tyres are cold where possible.

3

Use the correct settings

The recommended pressures are normally shown in the handbook, inside the fuel-filler flap or on a placard in a front door opening. Front and rear settings may differ.

4

Reinflate carefully

Adjust each tyre to the correct pressure. If one tyre is considerably lower than the others, it may have a puncture or leak that needs professional inspection.

After checking and correcting the pressures

The Warning Light Is Still On

Some vehicles switch the light off automatically after the correct pressures have been restored and the car has been driven for a short distance. Other vehicles require the TPMS to be reset manually.

Follow the procedure in your vehicle handbook or dashboard menu. Never reset the system before checking and correcting all tyre pressures, because the system may then treat an incorrect pressure as its normal reference point.

Why Might the Light Return?

Slow puncture or leaking valve

A tyre that loses pressure again after being inflated needs inspecting. Do not repeatedly top it up without finding the cause.

Temperature change

Cold weather can reduce tyre pressure enough to trigger the warning. Check and adjust the pressures rather than resetting the light without measuring them.

Sensor or system fault

A damaged sensor, depleted sensor battery or other TPMS fault may require diagnostic equipment and professional repair.
