RIfth e sy stem de tects that there are no lane
markings, it uses theve hicle ahead as a ref‐
erence up toa speed of 80 mph(1 30 km/h).
RWhen the sy stem is actively steering, the
è symbol is shown in green in the multi‐
function displa y.
St eering Pilot sy stem limits
St eering Pilot has a limited steering torque for
lateral guidance. In some cases, thesteering
inter vention is not suff icienttokeep theve hicle
in the lane.
If de tection of lane markings and vehicles ahead
is impaired, Steering Pilot switches topassive
mode. The sy stem pr ovides no support in this
case. During the transition from the active to
passive status theè symbol is shown as
enlar ged and flashes yello w. Once the sy stem is
passive theè symbol is gr ayed out in the
multifunction displa y.
The sy stem may be impaired or may not function
in thefo llowing situations:
RIf th ere is poor visibility, e.g. due toinsuf fi‐
cient illumination of thero ad, or due tosno w,
ra in, fog or spr ay.
RIfth ere is glare, e.g. from oncoming traf fic,
dire ct sunlight or reflection from other vehi‐
cles (e.g. if thero ad sur face is wet).
RIfth e windshield is dirty, fogged up, damaged
or co vered, for ins tance byast icke r,in the
vicinity of the camer a.
RIf no, or se
veral, unclear lane markings are
present for one lane, e.g. in a construction
area.
RIf th e lane markings are wornaw ay, dark or
co vered up, e.g. bydirt or sno w.
RIfth e dis tance totheve hicle in front is too
small and the lane markings thus cannot be
de tected.
RIfth e lane markings change quickl y,e.g.
lanes branch off, cross one ano ther or
mer ge.
RIfth ero ad is nar rowand winding.
RIfth ere are highly variable shade conditions
on thero ad.
RIfth ere are obs tacles such as traffic guid‐
ance posts on the lane or projecting out into

Note s onSteering Pilot
St eering Pilot is only an aid. You are responsible
fo rth e dis tance totheve hicle in front, forve hi‐
cle speed, for braking in good time and forst ay ‐
