The system checks the tyre pressure 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 appears in the multifunction display More.
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.
If the tyre pressure is set incorrectly.
If there is a sudden pressure loss caused, for example, by a foreign object penetrating the tyre.
