You can also use the tire pressure values for a fully
laden vehicle. These are always allowed and per-
missible. However, in a partially laden vehicle, the
ride is not as comfortable and fuel consumption is
only minimally reduced. In addition, wear is greater
in the middle of the tire tread.
Set the correct tire pressure before loading the
vehicle. Once the vehicle is laden, check the tire
pressures and correct them if necessary.

The system checks the tire pressure and the tire
temperature of the tires installed on the vehicle by
means of a tire pressure sensor.
New tire pressure sensors, e.g. in winter tires, are
automatically taught-in during the rst journey they
are used.

Note that the correct tire pressure for the current
operating situation must rst be taught-in to the
tire 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 tire pressure monitor
