I am having an issue with the intelligent cruise on my QX . The regular cruise works fine (hold the button for more than a second) but when I try to activate the intelligent cruise, I get the audible alarm and the whole cruise system shuts down until I restart the vehicle. Is this a common problem, radar alignment, or is it more serious? Any help will be greatly appreciated.

Thanks, VQX

First off, WELCOME TO NICOclub! Glad to have you as a new member. Try cleaning the I-Cruise box located in your lower front grille area. It is a black box that has nothing obstructing it. Make sure there is nothing on it (such as dirt, grime, a bird, or God only knows what!) Let me know what you find!

I did that; no difference. I just do not want to have to take it to the dealer, they are always a rip-off. Is there any connection with the navigation or convenience set up that I may have inadvertently screwed up? I really do appreciate the tips and if you know of any thing else, I would appreciate that too.

Thanks-VQX

No, I really can't think of anything else.

THanks just the same Timmbo, I appreciate the help.

I know this is a very old thread, but maybe someone stumbles on it with a similar issue. The first thing I would do is read out the cruise control error codes form the system. This can be done as follows:

1. Turn on ignition and wait 5 seconds
2. Rapidly push up on the accelerator button for the cruise control 5 times
3. Rapidly push down on the decelerator button for the cruise control 5 times

Now the codes will be displayed on the center DIC. You can check those codes against the descriptions in the below document

You can then also delete all codes by simply clicking the Cruise Control Cancel button 5 times in rapid succession.
