Fig. 158 In the centre console or in the stowage compartment on the front passenger side: button for the tyre monitor display
The tyre monitor display 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 monitor display in the instrument cluster.
Changes in the rolling circumference
The rolling circumference of a tyre can change:
The tyre monitor display may, in certain circumstances,
become slow or may not display anything, e.g. with a sporty driving style, winter
driving conditions or on unpaved roads or when driving with snow chains.
Calibrating tyre monitor display
The tyre monitor display will have to be re-calibrated after changing the tyre pressure and after changing one or several wheels. This also applies for changing the wheels, e.g. from the front to the rear.
The system calibrates itself independently in normal vehicle operation for the tyre pressures filled by the driver and the tyres that are fitted The recorded values are adopted and monitored after a long journey at various speeds.
If the wheels are loaded more heavily than normal, e.g. heavy payload, the tyre pressure must be raised to the recommended full-load tyre pressure before calibration .
