V70 D5 Mj.06: turning circle / function xenon light?

Good evening, after having covered 3000 km with my V70 in a short time and having finally “friended” me as a Volvo newcomer with the car, there are still 2 open points: 1. Turning circle: I experience the usual traffic space with my V70 every day, because I have to follow up at the places that went with my pass in a slide. Now Volvo indicates the turning circle with 11,9m, and my Passat 3BG was probably at 11,4m. The “feeled” and probably also realistic turning circle in the V70 is, however, significantly larger. Has someone already measured for fun (with the brochure value of the underlying and with me also mounted 215 standard tyres) times? 2. Xenon light: How does the automatic height control work in the V70? In the passat, one has already got the after-regulation during the ride with some longer floor waves, so a very quick system which affects the counter traffic at all possible.
