First read and observe the introductory information
and safety warnings
The tyre monitor display uses the ABS sensors to compare the rolling circumference and the vibration characteristics of the individual wheels. Any change in the tyre pressure of one or more wheels is shown by the tyre monitor display in the instrument cluster and infotainment system displays.
Changes in the rolling circumference
The rolling circumference of a tyre can change:
In certain circumstances, the tyre monitor display
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 monitor display
The tyre monitoring display will have to be re-calibrated 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 accepted 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 calibration .
The Tyre Pressure Monitoring System stops working if there is a fault in the ESC or ABS .
When using snow chains, an incorrect display may be shown as the snow chains increase the tyre circumference.
