7.2 Wheel Changes
Due to the external fixation of the wheel modules on the wheel bolts after wheel
change a new sensor is not needed. It is only to be ensured, that after wheel ex-
change the wheel module is fitted exactly to the same position as before.
As long as the wheel module itself is not exchanged, there is no need for new set-
tings of system parameters.
