When the tyre pressure monitoring system TPMS (Tyre Pressure Monitoring System) gives a warning, the tyre pressure is too low in one or more of the car's tyres.
If a tyre pressure message has been shown and the TPMS indicator lamp has been illuminated:
Check the tyre pressure on the indicated tyre/tyres with a tyre pressure gauge.
Inflate the tyre/tyres to the correct pressure in accordance with the tyre pressure label on the driver's side door pillar (between front and rear doors).
In some cases it may be necessary to drive the car for a few minutes at a speed above 30 km/h (20 mph) in order to clear the message. At which point, the TPMS indicator lamp is extinguished as well.
- The TPMS system uses a so-called compensated pressure value, based on both tyre temperature and ambient temperature. This means that the tyre pressure may differ slightly from the recommended pressures listed on the tyre pressure label on the driver's side door pillar (between front and rear doors). For this reason, it may be necessary to inflate the tyres to a slightly higher pressure in order to clear a low tyre pressure message.
- To avoid incorrect tyre pressure, the pressure should be checked on cold tyres. "Cold tyres" means the tyres are the same temperature as the ambient temperature (approx. 3 hours after the car has been driven). After a few kilometres of driving, the tyres warm up and the pressure increases.
- Incorrect tyre pressure may lead to tyre failure, which could result in the driver losing control of the car.
- The system cannot indicate sudden tyre damage in advance.
