2. Check (→ Tyre pressure) and adjust the tyre pressure for all tyres.
Fault in the Tyre Pressure Monitoring System
The indicator lamp flashes for around 1 minute and then remains lit up yellow continuously.
One or more wheels with a tyre pressure sensor have been fitted but have not yet been detected by the system.
1. Drive for a few minutes until the indicator lamp goes out.
One or more wheels without a tyre pressure sensor have been fitted or a tyre pressure sensor is defective.
1. Fit wheels with functional tyre pressure sensors.
There is a system fault.
1. Switch the ignition off and then back on again. If the fault persists, go to a correspondingly qualified workshop.
There is a transmission fault between the sensor and the system. The function of the system may be temporarily
impaired if there is interference from signals in the same frequency range as these transmitters.
1. Switch off or avoid any disruptive sources, e.g. wireless devices, remote controls or children's toys.
WARNING
Differing tyre pressures or tyre pressures that are too low can cause tyre damage, tyre failure, loss of vehicle
control, accidents, serious injury and death.
● If the indicator lamp lights up, stop immediately and check all tyres (→ Tyre pressure).
● Different tyre pressures or tyre pressures that are too low can increase wear on the tyres, reduce vehicle stability
and increase the braking distance.
● Differing tyre pressures or tyre pressures that are too low can cause sudden tyre failure and lead to a tyre
bursting and the loss of control over the vehicle.
● The driver is responsible for the correct tyre pressure of all tyres on the vehicle. The recommended tyre pressure
can be found on a sticker (→ Tyre pressure).
● The tyre monitoring system cannot function correctly until all cold tyres have the correct tyre pressure.
● The pressure in all tyres must always be appropriate to the vehicle load (→ Tyre pressure).
● Always inflate all tyres to the correct tyre pressure before every journey (→ Tyre pressure).
● If the vehicle is driven with insufficient tyre pressure, this results in greater tyre flexing. This could warm up the
tyre to such an extent that the tread may separate and the tyre could burst. This could cause the driver to lose
control of the vehicle.
● High speeds and overloading of the vehicle may cause the tyres to heat up to such an extent that the tyre bursts,
leading you to lose control of the vehicle.
● If the tyre pressure is too low or too high, the tyres will wear prematurely and the vehicle will not handle well.
● If the tyre is not flat and it is not necessary to change the wheel immediately, drive at low speed to the nearest
correspondingly qualified workshop and have the tyre pressure checked and corrected (→ Tyre pressure).
Introduction
The tyres are the most used and most underestimated parts of a vehicle. Tyres are very important as the narrow tyre
surfaces are the only contact between the vehicle and the road.
The service life of tyres is dependent on tyre pressure, driving style, handling and correct fitting.
Volkswagen Commercial Vehicles recommends that all work on tyres and wheels is carried out by a suitably qualified
workshop. They are familiar with the procedure and have the necessary special tools and spare parts and the proper
facilities for disposing of the old tyres.
