General information
The information about the mounted tires can
be entered in the tire settings if the system
does not automatically detect the tires.
The tire sizes of the mounted tires can be
gathered from the tire inflation pressure details
on the vehicle or directly on the tires.
The tire details do not need to be re-entered
when the tire pressure is corrected.
For summer and winter tires, the tire details
entered last are stored. After a tire or wheel
change, the settings of the tire sets used last
can be selected.
