How to use parking sensor feature

[RedRocket]

Interesting. So when I'm stopped behind a car and get up close, I would expect the sensors to go off? That definitely hasn't been happening. I will try walking around or using a piece of paper and see if the sensors react.

Mine are set on 3. First beeps are ~ 16 18 inches away and become *frantic* when front plate assembly is about 3 inches. Actually a pretty damn good parking sensor.

You cannot correlate a defined fixed distance warning beep to a specific selection number choice in the PDC table !
This is b/c you're not actually measuring distance, but rather the relative signal "strength" of the returned IR reflection from an object ahead.

Case in point:
My setting is the same as curmudgeon's. Sometimes the proximity warning beeps are the same as his or even 3-4 ft, but when the object is highly reflective it will give warning beeps at 8-10 ft.
