What do you mean ‘in and out?’
Is the system ON with the button left of the steering wheel?
Also understand the car has to identify the road lines for the system to work. This can be tricky at times, with bad pavement, or on some curves. If there are no straight vertical lines next to you car icon on the display (or HUD) the lane assist and warning system won’t work. That means it hasn’t detected the road lines.
