Calibrating
Calibrating means that the con-
trol is adapted to the effective
tire radii of the front and rear
wheel.
Effective tire radius
The effective tire radius de-
pends on the tire make, tread
depth, tire pressure and load.
Calibrate the ASC control af-
ter every tire change to com-
pensate for changes in the tire
radii.
Calibrate the ASC control regu-
larly as tire wear progresses to
maintain optimum operation.
Recalibration is not required
after removing and refitting
an unchanged wheel, e.g. for
brake servicing.
