ering and touch de tection
The driver is requiredtokeep their hands on the
st eering wheel at all times and be able tointer‐
ve ne at any time tocor rect the course of the
ve hicle and keep it in lane. The driver must
ex pect a change from active topassive mode or
vice versa at any time. If
th e sy stem de tects that the driver has not
st eered theve hicle for a considerable period of
time or has remo vedth eir hands from thesteer‐
ing wheel, display 1appears. If the driver still
does not steer theve hicle, a warning tone
sounds in addition tothe visual warning mes‐
sage. If
th e driver does not react tothis wa rning for a
considerable period, an emergency stop is initi‐
ated (/ page 205).
If th e driver steers, no warning is issued, or the
wa rning is ended.
If Ac tive Steering Assist de tects that a sy stem
limit has been reached, a visual warning is
