Function of the tyre pressure loss warning system

The tyre pressure loss warning system warns the driver by means of display messages when there is a severe tyre pressure loss.

After a change in tyre pressure, a wheel rotation or a tyre change, or if you have refitted wheels or tyres, the tyre pressure loss warning system has to be restarted More.

The tyre pressure loss warning system does not replace the need to regularly check the tyre pressures.

System limitations

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

incorrectly set tyre pressure
sudden pressure loss caused, for example, by a foreign object penetrating the tyre
