youto stay inthe center of the lane by
means of moderate steering inter ventions.
RIt uses theve hicle in front and the lane mark‐
ings as a refere nce depending on the driven
speed.
RAc tive Steering Assist requ ires you, as the
driver, tokeep your hands onthesteering
wheel at all times so that you are ableto
inter vene at any time tocor rect the course of
th eve hicle and keep it in lane.
RAc tive Steering Assist can be overridden at
any time bysteering theve hicle yourself.
RWhen the sy stem is actively steering, the
è symbol is shown in green in the multi‐
function displa y.
Sy stem limitations of Active Steering Assist
Ac tive Steering Assist has a limited steering tor‐
qu efo r lateral guidance. In some cases, the
st eering inter vention is not suff icienttokeep the
ve hicle in the lane.
If th e de tection of lane markings and vehicles
ahead is impaired, Active Steering Assist
switches topassive mode. The sy stem pr ovides
no support in this case. During the transition from
the active topassive status, theè sym‐
bol is shown as enlar ged and flashes yello w.
Once the sy stem is passive theè symbol is
gr ay ed out in the multifunction displa y.
