First read and observe the introductory information and safety warnings

The Tyre Pressure Loss Indicator uses data from the ABS sensors and other functions to check the speed of rotation and the rolling circumference of the individual wheels. Any change in the rolling circumference of one or more wheels is shown by the Tyre Pressure Loss Indicator in the instrument cluster.

Changes in the rolling circumference

The rolling circumference of a tyre can change:

In certain circumstances, the Tyre Pressure Loss Indicator may become slow or may not display anything, e.g. with a sporty driving style, in winter driving conditions, on unpaved roads, or when driving with snow chains.

Calibrating the Tyre Pressure Loss Indicator

The Tyre Pressure Loss Indicator will have to be re-synchronised after changing the tyre pressure, or after changing one or more wheels. This also applies when wheels are swapped, e.g. from the front to the rear.

During normal vehicle operation, the system calibrates itself independently to the fitted tyres and the tyre pressures filled by the driver. The calibrated values are stored and monitored after a long journey at various speeds.

If the wheels are loaded more heavily than normal, e.g. if the vehicle is carrying heavy payload, the tyre pressure must be raised to the recommended full-load tyre pressure before synchronisation   .

WARNING

Incorrect use of the setting button can cause the Tyre Pressure Loss Indicator to issue false warnings or to issue no warning despite dangerously low tyre pressure. Make certain the tyre pressure of all tyres is correct before using the setting button.

The Tyre Pressure Loss Indicator stops working if there is a fault in the ESC or ABS   .

If a warning is given about tyre pressure being too low, the vehicle must remain stationary for approximately one minute and should not be moved. Alternatively, the ignition can be switched off and then back on again. Only then can the Tyre Pressure Loss Indicator be synchronised using the tyre monitoring button  .

When using snow chains, an incorrect display may be shown as the snow chains increase the tyre circumference.
