Was ACC standard on the 2019 Tahoe Premier?

The subject says it all. I've got a 2019 and can't seem to engage the ACC.

Is there an RPO code for this option?

Thank you!

procedure should be shown in the owners manual, if it does not engage then you do not have it. Also some had active cruise, some had regular cruise, some had both.

In believe 2019 tahoes only has acc or regular and lacked the ability to change from acc to regular.

You have to hold the start stop button down for about eight seconds and that will put the truck into ACC mode,
My LT suburban with the luxury package has the start/stop button and that’s what I have to do to access ACC mode

Was the thread creator referring to accessory mode or adaptive cruise control?

 

[Lundgren]

Adaptive cruise control.

That's what I thought. Pressing and holding the cruise control on/off button for about 5 seconds is what activates it if you have it, from what I've read
