Detailed description: Calibration: Notes
WARNING: This page is about a different car, the 2006 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
Calibration takes place automatically if the battery has been disconnected/discharged or if the ACC unit has been disconnected or without power in some other way. Calibration also takes place automatically after the ignition has been turned off five times when the ignition has been turned off for at least two hours.
Calibration can be done using Tech 2 after replacing the stepping motor or its position has been changed manually. It is not possible to calibrate from the panel by pushing the buttons.
