nction of Active Steering Assist
Ac tive Steering Assist is only available for
ve hicles with the Driving Assistance Pack‐
age.
R Active Steering Assist is operational at
speeds up to210 km/h and helps youto stay
in the cent reofthe lane bymeans of moder‐
ate steering inter ventions.
R It uses theve hicle in front and the lane mark‐
ings as a refere nce depending on the driven
speed.
R Active Steering Assist requ ires you as the
driver, tokeep your hands on thesteering
wheel at all times so that you are able to
inter vene at any time tocor rect the course of
th eve hicle and keep it in lane.
R Active Steering Assist can be overridden at
any time bysteering theve hicle yourself.
R When 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 su fficient tokeep 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
shown as gr eyinthe multifunction displa y.
The sy stem may be impaired or may not function
in thefo llowing ins tances:
R Ifth ere is poor visibility, e.g. due toinsuf fi‐
cient illumination of thero ad, or due tosno w,
ra in, fog or heavy spr ay.
R Ifth ere is glare, e.g. from oncoming traf fic,
di re ct sunlight or reflection from other vehi‐
