Calibrating ASC
Requirement
Lower stability reserves of the
ASC control after a tire change.
NOTICE
Calibration means that the con-
trol is adapted to the effective
tire radii of the front and rear
wheels.
The effective tire radii depend on
the tire brand, tread depth, tire
pressure and payload.
Every time the tires are changed,
calibrate the ASC control to
adapt it to the new tire radii.
As tire wear progresses, calibrate
the ASC control regularly to keep
it functioning optimally.
Before calibration, the
ignition must have been
switched off for at least
1 minute.
Switch on ASC ( 70).
