Lane guidance won't turn off

[Toonces]

My buddy has a 10k mile 2023 Q8 and the lane guidance won't turn off. He asked me to help as he's not that internet savvy and I looked up where the button at the end of the turn signal bar turns this function on and off. When I'm driving his car I hit the button and a box pops up on the screen that says 'Adaptive cruise assist: without lane guidance' and the lane guidance stays on turning the wheel when I change lanes. I hit the button again and it says 'Adaptive cruise assist: with lane guidance' and just as it says the lane guidance is on and jerks the wheel when I change lanes. It's always on no matter what the screen says.

Am I doing something wrong, or does the dealer need to address this?

Thanks,
Brad
