Adaptive cruise control - can you enable it if you don't have a High Country?

I have a 2018 Traverse Premier with pretty much every optional feature I could pick. I have all the sensors, the display shows me how far behind the leading car I am, etc. However, adaptive cruise control was only an option on the High Country. I did not want the HC because of one reason -- I HATE HATE HATE the sh*t brown leather seats. I wanted black leather, but that is not an option on the HC. So I had to pick between ugly brown seats or adaptive cruise control. Funny how the seat color is a "compatibility issue" with the ACC. Anyway, is there a way to enable that, either yourself or through the dealer? I would imagine it is as simple as plugging the car in at the dealership and setting a sales code or something to flip the bit and enable it. If there is something I'm missing physically I'd like to know to. If they just won't do it because I don't like brown leather, that would be nice to know too.

Same with my Premier, the Redline package wasn't available on the High Country and brown leather would look even more out of place with a blackout look.


Same sensors but unlikely the dealer has the capability to install the software.......software updates are controlled by VIN and there will be a mismatch for the different models.



I wouldn't be too concerned about not having ACC.....had it in my Impala. Novel at first and might work OK on a cross country trip, but not in everyday traffic. Regardless of the following distance set, as soon as a car cuts in the lane, you slow down and dangerous if the tailgater behind you is playing with a cellphone.....I found it to be annoying and encourages cutting into your lane and wouldn't have the dealer activate it even if he could.

That's what I've been telling myself. Just did a road trip and it would have been nice at times to have the ACC (I think, never actually used it myself). My gripe is more with their choice to only include it as a feature (optional or otherwise) on a rather restricted version. You'd think if we are paying *that* much for a vehicle they would be a bit more accommodating. But to tie brown leather with ACC is dumb.

I'd still like to know if it's possible. But you're probably right, it's probably something stupid like a software licensing issue (cars are becoming rolling computers more and more) and this might even be a restriction set by the software manufacturer for the ACC, whoever that is. Pretty sure all the automakers get these features from the same place.

Adaptive Cruise Control has unique sensors and software. I would not recommend trying to add it in on a vehicle that wasn't "factory-built" with it.

Much of the time these features are present on all models, as a cost saving measure, then disabled in the software. This is pretty standard practice in most industries. From everything I have seen thus far, all the sensors are present in the Premier, and I would not doubt for a second that the software for Adaptive Cruise Control is also present and missing a license file or some setting that can only be enabled by a dealership or perhaps at the factory.

My hope in posting this question was to get a definitive answer from someone that knows for sure so I can put this issue to bed. So far, everything I've read or heard about the topic is speculation.

The Adaptive Cruise Control-equipped units have a different radar sensor out front. It, along with the sensor behind the windshield, provide the critical data to make the Adaptive Cruise work. Adding that extra sensor, and the wiring to the different modules would be a giant task. On top of the physical part changes, there are at least three modules that would have to be reprogrammed.

It seems you have some knowledge on this topic. I know my vehicle has a radar sensor since I can see how may seconds I am behind the leading car, as well as having the collision avoidance feature. What you're saying is there is either an additional radar or an upgraded radar on the models with adaptive cruise, correct?

As for flashing the modules, if this were something that was available, there would be provisions at the dealership to do that. However it is sounding like something that 1) cannot be done youself, 2) is unlikely to be available through a dealer at this time.

This isn't really a problem, I have been living without adaptive cruise control for over 25 years of driving, it is just crazy that they tied it with only the High Country and therefore, that seat color.

The following distance function is handled through the windshield-mounted camera, near the inside rear view mirror. The adaptive cruise function uses that sensor PLUS a radar device mounted in front of the condenser and radiator, low on the driver's side. And yeah, I know the second generation product pretty well

All sensors are included in the Premier including the LED for the ACC idiot light. But that doesn't mean that the dealer can install a software set to add the ACC option. Software installation and changes are controlled by the VIN stored in the ECU.



Windshield camera is coupled to object recognition software used for lane detection, vehicle ahead identification, the dash idiot lights, intellibeams, electric steering and tranny output sensor used for speed detection. The front grille camera is only used for a front when traveling forward under 5mph and the 360 surround view in the DIC. Radar sensor is used to determine following distance for the ACC, but also for feedback in conjunction with the low speed braking, pedestrian detection and to trigger heads up warning LEDs in the Premier, and other models equipped with the optional detection packages.



Indication that the front windshield camera is not used for low speed braking and pedestrian detection is because these function remain operative under adverse visual road conditions such as a heavy rain downpour, blizzard or fog, whereas under these conditions lane detection is inoperative and sometimes automatically turned off with a DIC warning under these same conditions (with a vehicle stop and restart once road conditions are cleared to reactivate using the console button - happened on once during a really heavy rain)

I had the same dislike for the brown interior... I guess others did as well, since my new highcountry was available with black interior! :-)

And yes, it had ACC. I have used it enough to know if I like it, but I love it on trips in my Tundra.
