Function of Active Lane Keeping Assist
A

ctive Lane Keeping Assist monitors the area in
front of your vehicle by means of the multifunction
camera (  page 264) and can warn you before
you leave your lane unintentionally. The system
can guide you back into your lane through a
course-correcting steering intervention and addi-
tionally warns you with vibration pulses in the
steering wheel. Active Lane Keeping Assist is
available in the speed range between 60 km/h
and 200 km/h. 298
Driving and parking

The system can intervene in the following situa-
tions:
= A
ctive Lane Keeping Assist detects a lane
marking.
= One of your front wheels goes over a lane
marking.
If you activate the turn signal indicator, a steering
intervention does not occur on the corresponding
side.
If the system detects an obstacle, such as another
vehicle in the adjacent lane, a steering interven-
tion occurs regardless of the turn signal indicator.
If you leave the lane without activating the turn
signal indicator, but danger of a collision with a
moving obstacle is detected in your lane, a steer-
ing intervention does not occur. Display
1 will appear in t
he driver's display and a
warning tone will sound in the following situations:
= A steering intervention by Active Lane Keeping
Assist lasts longer than approximately ten sec-
onds.
= The system carries out two or more steering
interventions within approximately three
minutes without any steering intervention from
the driver.
In the Active Lane Keeping Assist settings, you
can set the sensitivity of the system and set the
level of support. Additionally, you can set whether
the system should react to discontinuous lane markings or only continuous lane markings
( pag

e 301).

erate.
= If a driving safety system intervenes, such as
ESP n
, Active Brake Assist or Active Blind Spot
Assist.
= You have adopted a sporty driving style with
high cornering speeds or high rates of acceler-
ation.
= If transport equipment, forexample a trailer or
bicycle rack, is attached to the trailer hitch
and the electrical connection has been cor-
rectly established.
The system may be impaired or may not function
particularly in the following situations:
= If there is poor visibility, e.g. due to insuPcient
illumination of the road, highly variable shade
conditions, rain, snow, fog or heavy spray. =
If t here is glare, e.g. from oncoming traPc, the
sun or reOections.
= If there is dirt on the windscreen in the vicinity
of the multifunction camera or if the camera is
misted up, damaged or obscured.
= If there is dirt on the bumper in the area of the
radar sensors, or if they are damaged or cov-
ered.
= If there are no lane markings, or several
unclear lane markings are present for one
lane, e.g. around roadworks.
= If the lane markings are worn, dark or cov-
ered.
= If the distance to the vehicle in front is too
short and thus the lane markings cannot be
detected.
= If the lane markings change quickly, e.g. lanes
branch oM, cross one another or merge.
