How to use crawl control features

You don't have to be in park or neutral to engage 4 wheel drive you can engage while driving under 25 mph also.

 

Correct but most of the time in motion the truck makes a loud clunck sound from it engaging I don't like the sound so I just don't do it while moving unless I have to, the only time that's ever happened while I was in snow and it doesn't snow at all here. Well not much anyway.

 

I was testing out CC for the first time this weekend and heard this: https://youtu.be/U6NB_VFSims

Is this the clicking sound you're referring to? I was on a gravel road with slight grade and a lot of potholes.

 

Yes, that is the booster firing individual brake lines

 

Yes. Exactly. It should go away once you hit an incline.

 

It will only stop if all 4 wheels are spinning the same speed. If you go down that incline, it will never stop
