I have a 2008 XLR, I have went thru the owners manual and can't find an answer. On my other cars, I can disable the adaptive cruise control so that it maintains the set speed and does not change. This is done by pushing 2 cruise control buttons at the same time.
Anyway, is there a way to disable adaptive cruise besides setting the gap to the smallest value?
 
On the left side stalk, there's a three-position switch facing the driver. Move it to the left to disable the cruise control system. The center position enables it, and the right position resumes a set speed and can incrementally increase the cruise speed.

(Straight out of the owner's manual, with a picture too.)

I don't think you can override the adaptive cruise control. I'm sure if you remove the radar sensor the system stops working altogether.
 
That will definitely disable the ACCS, but then it will light the DIC up with an error message.

Why would any cruise control system be permanently engage without a way to turn it off? The owner's manual shows controls and indicators.

Every Cadillac I've owned had to have the CC energized manually before enabling the system to command a set (or pre-set) speed to the ECM.
