Also in the US if you long press the blue pro pilot button the standard cruise control icon lights up instead & you have traditional cruise control with out any of the LKA, car controlled following distance, etc. An interesting anecdote is std cruise accelerates to the set speed quite a bit slower than pro pilot but the minimum speed is 25mph instead of 20mph for pro pilot
Perhaps try long pressing some of your buttons & see what happens
And if you turn off the steering control via the button to the left of the steering wheel next to the charge door release button Pro pilot becomes adaptive cruise control.
