I had no problem choosing speed, what I couldn’t do was specify a distance to the vehicle in front, not way to adjust distance and no display to even show distance.
It’s the button, bottom right of steering wheel in photo, which looks like the front of a car with 3 ‘radar waves’ coming out of the front. Press this button once for 3 distance blocks from car in front – twice for two blocks & three times for one distance block to car in front.
Pressing it also brings up an image of the car & each block on the small TFT screen in front of the driver.
