What the tyre-pressure warning means

Distinguish low pressure from a TPMS signal or system fault and know what to do next.

QUICK ANSWER

What to do

A solid warning with a yellow tyre value indicates low pressure. A warning that flashes and then stays on, together with an abnormal signal or Check TPMS message, indicates a sensor, signal or system problem.

STEP BY STEP

Follow these steps

  1. 1

    Reduce speed, avoid sharp steering or heavy braking, and stop safely.

  2. 2

    Inspect the indicated tyre for visible damage or rapid air loss.

  3. 3

    Check all pressures when safe and inflate to the vehicle's specified standard value.

  4. 4

    If the display reports an abnormal signal or Check TPMS, arrange inspection of the monitoring system.

GOOD TO KNOW

Before you finish

  • The low-pressure alarm is triggered below 80% of the standard pressure and stops after pressure rises above 95% of the standard value.
  • The system normally displays live pressures between approximately 19 and 99 mph (30-160 km/h).
  • Wireless interference can temporarily affect the signal.
  • A sudden puncture may develop before the next sensor transmission, so do not rely only on the display.
