Ste ering Pilot
Function of Steering Pilot
Ste ering Pilot is only available forve hicles
with the Driving Assistance Package.
RSteering Pilot is operational at speeds up to
13 0mp h(210 km/h) and helps youto stay in
th e center of the lane bymeans of moderate
st eering inter ventions.

Driving and pa rking

RIt uses as arefere nce theve hicle in front or
th e lane markings, depending on the driven
speed.
RSt eering Pilot requiresyou as the driver, to
ke ep your hands onthesteering wheel at all
times so that you are abletointer vene at any
time tocor rect the course of theve hicle and
ke ep it in lane.
RSteering Pilot can be overridden at any time
by steering theve hicle yourself.
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 (130 km/h).
RWhen the sy stem is actively steering, the
è symbol is shown in green in the multi‐
function displa y.
Sy stem limitations of Steering Pilot
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 shown as gr ayinthe
multifunction displa y.
The sy stem may be impaired or may not function

RIf th e lane markings are wornaw ay, dark or

RThe distance totheve hicle in front is too

St eering Pilot is only an aid. You are responsible
fo rth e dis tance totheve hicle in front, forve hi‐

th at the neighboring lane is free (shoulder view). %
The availability of thefo llowing function is

St eering Pilot remains active even if the turn sig‐

assists the driver when changing lanes byapply‐
ing steering torques toinitiate the lane change.
Assis tance when changing lanes is pr ovided if all
