Function of tyre pressure monitor on Single tyres

The system checks the tyre pressure and the temperature of the tyres fitted to the vehicle by means of a tyre pressure sensor.

New tyre pressure sensors, e.g. in winter tyres, are automatically taught-in the first time they are driven.

The tyre pressure and the tyre temperature appear in the multifunction display More.

If there is a substantial loss of tyre pressure, a warning is issued:

via display messages More More More More More More More
via the warning lamp in the instrument cluster

It is the driver's responsibility to set the tyre pressure to the recommended cold tyre pressure suitable for the operating situation. Set the tyre pressure for cold tyres using a tyre pressure gauge. Note that the correct tyre pressure for the current operating situation must first be taught-in to the tyre pressure monitoring system.

In most cases, the tyre pressure monitoring system will automatically update the new reference values after you have changed the tyre pressure. You can, however, also update the reference values by restarting the tyre pressure monitoring system manually More.

System limitations

The system may be impaired or may not function in the following situations:

if the tyre pressure is set incorrectly
if there is a sudden pressure loss caused by a foreign object penetrating the tyre, for example
if there is a malfunction caused by another radio signal source
