Calibration Procedure

WARNING: This page is about a different car, the 2008 Cadillac STS. However, it is still accessible from the selected car via links, so may be relevant.

Conditions to complete the self-calibration procedure:

Operating the vehicle at 35 mph or more
Clear stretch of straight road
Visible references (lane markings, curb, guard rail, etc.)

One or more of the following conditions may increase the length of time required to complete the self-calibration procedure:

Operating the vehicle at 19 to 38 mph
Curves in roadway
Driving through snow, fog, or driving at night or directly into the sun
Bott's Dots type lane markings
Poor contrast lane markings

Conditions that will prevent completion of the self-calibration procedure:

Operating the vehicle at less than 19 mph
No visible lane markings

When the VDAAW system is in calibration mode, the amber light in the IPC will remain illuminated. When the calibration is complete, the amber indicator will turn green, indicating the system is ready to assist.

If the VDAAW system is disabled with the VDAAW switch, the amber light will turn off. The system will still run the calibration procedure in the background.

Immediately after the self calibration procedure, there may be a delay in lane crossing alerts. The VDAAW system will run further calibration tests as the vehicle is driven in order to improve performance.
