System calibration If control indicators c and b
illuminate simultaneously, a
calibration of the power steering
system is necessary. This can occur
e.g. when turning the steering wheel
for one rotation with ignition switched
off. In this case, switch on ignition and turn steering wheel once from lock to
lock.
If control indicators c and b do not
extinguish after calibration, seek the
assistance of a workshop.Driver assistance
