Active Steering Assist
Function of Active Steering Assist
Active Steering Assist assists the driver at
speeds up to130mp h (2 10km/h) and helps the
driver tostay inthe center of the lane bymeans
of moderate steering inter ventions. The sy stem
orients itself using de tected lane markings.
Depending on the speed driven, Active Steering Assist uses
theve hicles ahead as a refere nce. If
th e de tection of lane markings and vehicles
ahead is impaired, Active Steering Assist
switches topassive mode. The sy stem does not
pr ov ide support in thefo rm ofsteering inter ven‐
tions.
RThe driver is requ ired tokeep their hands on
th esteering wheel at all times and be able to
inter vene at any time tocor rect the course of
th eve hicle and keep it in lane.
RThe status of Active Steering Assist is dis‐
pla yed in thest atus bar of the multifunction
displa y.
Ste ering and contact de tection
The driver is requ ired tokeep their hands on the
st eering wheel at all times and tobe able to
inter vene at any time. The driver must expect a
ch ange from active topassive mode or vice
ve rsa at any time.

Driving and parking

Ifth e sy stem reaches a sy stem limitation or the
driver has not steered theve hicle for a consider‐
able period of time or has remo vedth eir hands
from thesteering wheel, the sy stem will,
depending on the situation, firs t alert the driver
with a visual warning. Display 1appears in the
multifunction displa y.Ifth e driver still does not
st eer theve hicle himself or herself, or still has
not take n hold of thesteering wheel, a repeated
wa rning tone sounds in addition tothe visual
wa rning message toremind the driver totake
control of theve hicle.
The warning message does not appear or disap‐
pears if one of thefo llowing conditions are me t:
RThe driversteers theve hicle.
RThe driver presses a steering wheel button or
operates Touch Control.
Ac tive Steering Assist is only an aid. The driver is
re sponsible forth e dis tance totheve hicle in
front, forve hicle speed, for braking in good time
and forst ay ing in lane. Before changing lanes,
th e driver must make sure that the neighboring
lane is free (glance over the shoulder).
Sy stem limitations
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 lan
e or todrive past exits. Active
St eering Assist cann otprov ide the driver with
st eering assis tance at traf fic circles, T-intersec‐
tions, intersections, tollst ations or turnings, for
ex ample.
The sy stem may be impaired or may not function
in thefo llowing ins tances:
RIn sno w,rain, fog, heavy spr ay, if there is
gl are or direct sunlight or if there are greatly
va rying ambient light or reflections, or strong
shado wsonthero ad.
RInsuf ficient road illumination.
RThe windshield in the area of the camera is
dirty, fogged up, damaged or co vered.
RAbsence of lane markings, or se veral unclear
lane markings, or if the markings change rap‐
idl y.
RThe dis tance totheve hicle in front is too
small and the lane markings thus cannot be
de tected.
RThe road is nar rowand winding.
RObstacles on the lane or projecting out into
th e lane.
The sy stem does not pr ovide assis tance in the
fo llowing conditions:
ROn tight bends, traf fic circles and when turn‐

MAGIC BODY CONTROL is an electrohydraulic
suspension with variable damping for impr oved
driving comfort. The all-round le vel control sys‐
te m ensures the best possible suspension and
const ant ground clearance, even wi tha laden
ve hicle. When driving at speed, theve hicle is
lo we red automatically toimpr ove driving saf ety
