Verify if the radars are "Mature alignment".
If yes, vehicle should be ready for DRIVE PILOT use.
If no, begin process again with the park and key cycle. If after a second attempt the radars are not calibrated to "Mature".
Try a different plaza. If radars still do not calibrate to "Mature", open a TIPS case.

3.Verify all system activation conditions are met as prescribed by the Owner's Manual and Drive Pilot Supplement.
4.If after verifying all short range radars have been calibrated and the system activation conditions are met yet the cluster message
still appears, open a TIPS case.
