Adjusting active backrest width*
First set a comfortable backrest width, see

The adaptation of the backrest width and the
speed of the adjustment vary depending on the
program. You can select from among three pro-
grams from comfort to sport. The "Sport" pro-
gram provides increased lateral support on both
sides when driving through a quick succession
of curves.
