You can test it this way very easily.
When a car is signaling a right turn in front of you, don't have your foot on either pedal. As the car in front starts to make the turn, if you're close enough, the system will beep, beep again louder and then start to apply the brakes until the car is out of the radar zone.
If you have your foot on the accelerator even a little, it will over ride the warning system. It a little nervy the first time, but you just need to trust it. Also, I wouldn't try this with another car right behind me.
The second way to see it working.
Set cruise control and leave the distance bar at three. As you come upon a car in the right lane, wait until you are about four car lengths away and pull in behind the car. You will feel the car slow down to match the car's speed in front now. If you're close enough and a bit faster then the car in front, brakes will be applied also.
I'm making a 40 mile run frequently. I set my CC to 72 and one distance bar. I go thru two major interchanges and one construction zone and never touch the brakes. I do tap the gas to bring the car back up to speed a little quicker then the CC will do.
A little scary the first time you come up on heavy traffic to just let the system do it's job. I've even had a jerk pull in front of me and slam on the brakes trying to make his exit and misjudged the speed of the car in front of me slowing down also. The system applied the brakes to the point the ABS kicked in and the system kept a distance of about three feet. I was extremely lucky the there wasn't a car close behind me.
I've found it to work just about flawless, although it does shut down in snow, but only a fool uses CC on anything other then a dry road.
Have a good day.
