2023 Silverado 1500 RST adaptive cruise function

kickass audio · October 29, 2023

So before the big GM issue due to the system update that caused the transfer case control module to break I tried to switch between normal cruise control and adaptive cruise control but when I held the cancel button for cruise control as indicated in the owners manual to switch to adaptive cruise, the standard cruise disappeared from the DIC and I could not get it back on. I had to fiddle around and finally was able to hold the cruise cancel button for like a minute straight and went back to standard cruise mode.

My question is for those who have adaptive cruise, how long do you hold the cancel button on the wheel to flip between adaptive cruise and standard cruise control? Also, do you have the front radar sensors in the bumper? I have forward collision avoidance so i'm not sure if adaptive cruise works with the camera on the windshield or if it works on the higher end trim levels with the 360 camera view where one of the cameras is just below the bowtie on the grille? Also, can you switch between adaptive cruise and standard cruise modes when at a dead stop or does adaptive cruise require you to meet a minimum speed to switch modes without even having it engaged?

So I tried again to test switching to adaptive cruise control and still nothing. This time around though I could not get it back to normal cruise control. I stumbled across someone on another forum who had a similar problem and he fixed it by pulling fuse F11 in the passenger side dashboard fuse box and waiting 5 minutes and then put the fuse back in and start the truck and normal cruise control worked again.

I really think my truck does not have adaptive cruise but just figured i'd see what those who have ACC have for additional features and trim levels.

If it didn't work before the update, then you don't have ACC.

Pulling the fuse F11 is largely a forward collision glitch fix but I assume if ACC was optioned and the camera glitched, then sure it would reset that.

I switch mine occasionally. (I use adaptive almost all the time)

Adaptive cruise is optional on 2023 1500 RST.

If you want to verify adaptive is installed, check the QR code on the truck, the option code (rpo code) is KSG

Note 2 applies to 2023 RST 1500

It is the left button to switch modes.

The switch between modes only takes a few seconds. (2 or 3?)

I haven't tried, but presumably the cruise must be 'on' (RH button) for it to change modes.

I never shut off (RH button) the cruise -- I just use LH button (or brake pedal) to 'pause' cruise operation.

Pretty sure I used the on/off button (right side) to switch modes on mine.

ahh thanks a ton for sharing that!! So reading the detail for options available on the 2023 it shows the RST all star edition as not available for RST redline edition which is definitely why I don't have it because I have a redline and the seats are cloth not leather. Oh well. One would think that GM would not have it lock up hard if you hold the button down and lack the feature when it tries to switch over and it would just give up and leave the cruise control alone but I guess not haha.

'23 manual shows the LH button. (with the big X thru the symbol)

Maybe they both do it?

Footnote 2 "requires Convenience II package". All RSTs have AllStar which includes convenience I. You can option up to Convenience II or you can get All Star Premium (or Texas Premium) which will include Convenience II which then allows it to add the $500 option for Adaptive Cruise.

If you have buckets in the front so the full center console instead of the jump seat, you have Convenience II, but then they didn't order Adaptive Cruise in addition to that.

Nope. Memory is the first thing to go, as they say.

I could have sworn I had used the On/Off but I just double-checked last night and only the Cancel button switches modes. Just like it says in the manual. Imagine that! lol
