Beeping in 4L is an indication that it’s not engaged. Does it actually feel like it is?While test driving the vehicle I was unable to get the crawl control to engage. I would place the vehicle in 4L and then in Drive before hitting the crawl control button. The display kept saying the vehicle had to be in "D" or "R" to engage even though I was already in drive. Also, the vehicle is beeping non stop while in 4L. I've been trying research what might be causing this (operator error vs. issue with the vehicle itself) but I'm not having much luck.
