Adaptive Cruise Stop-and-Go Auto-Resume vs Stopped

[xtraman122]

Does anyone know what makes the truck decide whether to "Auto-Resume" certain times in traffic vs give you the 3 seconds of being stopped and require manually resuming? I can't figure out the rhyme or reason behind it at all.

Half the times I want it to crawl in traffic for me it'll just give me the "Stopped" message on the cluster and require me to keep hitting the gas or resume button once it's stopped for more than 3 seconds, but other times it says "Auto Resume" when it stops which means it's going to work correctly and resume like it should after being stopped for more than those 3 seconds.

Less than 3 seconds the auto-resume works for up to 30 seconds. So after the 30 seconds you have to click the button or press the pedal. Image below taken from manual.

In my head I was trying to figure out why they would do this. My thinking is because it probably can’t detect your hands on the wheel in stop and go traffic.

The “after following a vehicle to a complete stop” is the part I’m interested in I guess. That seems to be hit or miss, sometimes it works fine snd does auto-resume, other times it keeps doing the “stopped” thing which is very frustrating.

As earlier post said it should be based on your location - stop and go on city street vs freeway.

In my experience, if I am on a City street at say a stop light it is based on 3 seconds, and if it’s stop and go on a freeway it’s more like 30 seconds. My guess is the city is so that if you are say at a light and the person in front of you turns right on red you don’t just automatically drive straight through a red light (because there are no cars in front of you). On a freeway this time issue.
