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
Reduce speed, avoid sharp steering or heavy braking, and stop safely.
- 2
Inspect the indicated tyre for visible damage or rapid air loss.
- 3
Check all pressures when safe and inflate to the vehicle's specified standard value.
- 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.
