If you don't start to brake and you have distance required to x car lengths then it will start to brake to Maintain that distance. Also if someone is in your blind spot steering in that direction will be restricted. Max braking can occur stopping the maverick about 30" from contact. Someone cut across my lane from passing to make a right turn but he had to stop with 1/2 his vehicle in my lane.
Makes sense, but the distance between us is significantly greater than the following distance ACC allows, and is set for in my case.
Good to hear! Thanks for responding. I have a feeling the Santa Fe will be our choice.
That's not true. You can turn collision warning/ assist permanently off even after you restart the vehicle.Dennis, @Busa789
Pre collision assist is what you probably experienced.
I have mine set at High the most sensitive setting. I want plenty of notice.
It has never activated the brakes.
According to the 2025manual you can turn it off. Temporarily.
At the bottom of the page it also notes that it will reactivate when you restart your truck. In other words it's not something that you can permanently disable.
The brake lights do illuminate
When the truck activates collision avoidance and applies the brakes.
Please show us how to permanently turn off the collision warning assist
it isn't the pre collision that's doing it - when the pre-c is triggered you get a big old rectangular red box on your dash and a lot of beeping - you didn't mention that in your post so that's not it. I've had my pre-c fire up 4 or 5 times over a few years, it sort of over-reacts but it for sure isn't firing off for no reason at all.
Yeah, that's what I was thinking would be the case. I mentioned I didn't see or hear any warning on the dash. It would seem adaptive cruise shouldn't be doing it since it is well beyond the following distance I set. That's why I said "some form" of automatic braking ... not sure what it is.
It has to brake before you get to the following distance. Will brake at maybe , twice the set distance if the relative speed difference is 20-30 mph faster. It will match your speed to the other vehicle's speed at the set distance.
During normal operation of the adaptive cruse, when someone is and has been directly in front of me, it gets closer then brakes. It seems to be working properly. When someone is merging, it seems to be a greater distance, the truck brakes harshly for a moment, then often resumes to the set speed. It could well be the adaptive cruise doing it, but it doesn't seem appropriate. One other thing is that it has occurred when using regular cruise also.
It's definitely the adaptive cruise. Pre collision assist will make more noise than an annoyed R2-D2 before it takes action.
You need to expand your list of automotive companies to include all of them, and the reason these features exist is due to federal automotive safety requirements.
That seems odd, and braking for a merging car when you use CC rather than ACC sounds like it's a sensitivity issue or error with automatic braking rather than the cruise itself.
