Does the PD1 rear sensor have to be reset after it has run its alert cycle?
Once the PD1 system has completed its full cycle of zones 1, 2, 3 (alert/stop) the system will then need to be reset if you want the alerts again during the same parking manoeuvre. However, if when parking you only get alert zones 1 and 2 the PD1 system will continue to work and alert you, its only when you have hit zone 3 (alert/stop) that you need to reset the system (by selecting reverse gear again) to reactivate the PD1. Likewise if you have parked within say 20cm of an object, when you reativate the system it will once again alert you to this object (once you start moving backwards – see question below) because switching off the system resets the PD1.
