I have a 2014 Buick Regal wth the Premium II package.In the description of this package it says I have :
(Following Distance Sensor Indicator, Forward Collision Alert, Rear Cross-Traffic Alert, and Side Blind Zone Alert w/Lane Change Alert),
with integrated turn signal indicators Rear Parking Assist, Ultrasonic with audible warning.
What I want to know is are all these sensors working correctly. Should I be able to pull up OR back up to my garage door and when I get close the sensors should notify me that I am close with a visual and sound alarm?
