I went to turn lane keeping off and I don't see that option. Only warn or warn and aid I believe, in advanced setting of dash screen?
You disable lane keep assist via a button behind the shifter on the center console. A way you can tell it’s enabled:
Depending on what display you have, at the bottom center of the display is a “road way” icon
While lane keep assist is enabled, once you’re over the threshold speed (it’s in the manual and I don’t remember it ), there are arrow icons on the left and right of the roadway. If you’re within the lines, the arrows are green.
If you get close to a line, that side goes yellow
If you’re really close, on the line or over, the arrow goes red.
If the arrow is red, you either are about to get corrected or you already are being corrected.
In warn, it just vibrates the wheel, and I believe the red arrow flashes.
In warn and aid, it vibrates the wheel, and steers you back. Now, it won’t keep you from doing something insanely stupid, but so far I’ve found it useful.
HTH
