The system checks the tyre pressure and the tyre temperature 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 during the first journey they are used.
It is the driver's responsibility to set the tyre pressure to the recommended cold tyre pressure suitable for the operating situation More.
Note that the correct tyre pressure for the current operating situation must first be taught-in to the tyre pressure monitoring system. If a substantial loss of pressure occurs, the warning threshold for the warning message is aligned to the taught-in reference values. Restart the tyre pressure monitor after adjusting to the cold tyre pressure More. The current pressures are saved as new reference values. This will ensure that a warning message will only appear if the tyre pressure drops significantly.
warning lamp in the instrument cluster displays a detected pressure loss or a malfunction as follows: if the
warning lamp is lit continuously, the tyre pressure on one or more tyres is significantly too low. The tyre pressure monitor is not malfunctioning. if the
warning lamp flashes for around a minute and then remains lit constantly, the tyre pressure monitor is malfunctioning. a message also appears in the instrument cluster.
the tyre pressure has been set incorrectly.
there is a sudden pressure loss caused, for example, by a foreign object penetrating the tyre.
there is a malfunction caused by another radio signal source.
If the tyre pressure monitor is malfunctioning, it may take more than ten minutes for the tyre pressure warning lamp to inform you of the malfunction. When the fault has been rectified, the warning lamp goes out after you have driven for a few minutes.
The tyre pressure values indicated by the on-board computer may differ from those measured at a filling station using a pressure gauge.
The tyre pressures shown by the on-board computer refer to those measured at sea level. At high altitudes, the tyre pressure values indicated by a pressure gauge are higher than those shown by the on-board computer. In this case, do not reduce the tyre pressures.
