System limitations
No lane-correcting brake application occurs in
the following situations:
R
You clearly and actively steer, brake or accel‐
erate.
R
You have switched on the turn signal indica‐
tor.
R
A driving safety system intervenes, such as
ESP
®
, Active Brake Assist or Active Blind
Spot Assist.
R
You have adopted a sporty driving style with
high cornering speeds or high rates of accel‐
eration.
R
ESP ® is deactivated.
R
If a loss of tire pressure or a defective tire
has been detected and displayed.
The system may be impaired or may not function
in the following situations:
R
If there is poor visibility, e.g. due to insuffi‐
cient illumination of the road, highly variable
shade conditions, or due to rain, snow, fog or
heavy spray.
R
There is glare, e.g. from oncoming traffic, the
sun or reflections.
R
If there is dirt on the windshield in the vicin‐
ity of the multifunction camera or the camera
is misted up, damaged or obscured.
R
No or several, unclear lane markings are
present for one lane, e.g. near roadworks.
R
The lane markings are worn, dark or covered.
R
The distance to the vehicle in front is too
small and the lane markings thus cannot be
detected.
R
The lane markings change quickly, e.g. lanes
branch off, cross one another or merge.
R
The roadway is very narrow and winding.
Vehicles with Driving Assistance package or
Driving Assistance Plus package: Active Lane
Keeping Assist uses radar sensors to monitor
several areas around the vehicle. If the radar
sensors in the rear bumper are dirty or covered
with snow, the system may be impaired or may
not function. If an obstacle in the lane in which
you are driving has been detected, no lane-cor‐
recting brake application occurs.
Activating Active Lane Keeping Assist
& WARNING Risk of accident despite
Active Lane Keeping Assist warning
A lane-correcting brake application cannot
always bring the vehicle back into the origi‐
nal lane.
#
Always steer, brake or accelerate your‐
self, especially if Active Lane Keeping
Assist warns you or makes a lane-cor‐
recting brake application.
&
WARNING Risk of accident despite inter‐
vention of Active Lane Keeping Assist
Active Lane Keeping Assist does not detect
traffic conditions or road users. In very rare
cases, the system may make an inappropri‐
ate brake application, e.g. after intentionally
driving over a solid lane marking.
The brake application can be interrupted at
any time if you steer slightly in the opposite
direction.
