steering MERCEDES-BENZ C-Class SEDAN 2015 W205 Repair Manual

Important safety notes
If you fail to adapt your driving style, Active
Lane Keeping Assist can neither reduce the
risk of accident nor override the laws of phys- ics. Active Lane Keeping Assist cannot take
account of road and weather conditions. It
may not recognize traffic situations. Active
Lane Keeping Assist is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
Active Lane Keeping Assist cannot continu-
ously keep your vehicle in its lane. G
WARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can:
R give an unnecessary warning and then
make a course-correcting brake application
to the vehicle
R not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you. Ter-
minate the intervention in a non-critical driv-
ing situation.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray
R there is glare, e.g. from oncoming traffic,
the sun or reflections (e.g. when the road
surface is wet)
R the windshield is dirty, fogged up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R the radar sensors in the front or rear bump-
ers or the radiator grill are dirty, e.g.
obscured by snow R
there are no, several or unclear lane mark-
ings for a lane, e.g. in areas with road con-
struction work
R the lane markings are worn away, dark or
covered up, e.g. by dirt or snow
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 road is narrow and winding
R there are strong shadows cast on the road
If no vehicle is detected in the adjacent lane
and there are broken lane markings detected,
no lane-correcting brake application is made.
Warning vibration in the steering wheel
A warning may be given if a front wheel
passes over a lane marking. It will warn you by
means of intermittent vibration in the steer-
ing wheel for up to 1.5 seconds.
Lane-correcting brake application
If you leave your lane, under certain circum-
stances the vehicle will brake briefly on one
side. This is meant to assist you in bringing
the vehicle back to the original lane. G
WARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake appli-
cation. Driving systems
225Driving and parking Z

If a lane-correcting brake application occurs,
display 0043appears in the multifunction dis-
play. The brake application also slightly
reduces vehicle speed.
This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
A lane-correcting brake application can be
made after driving over a lane marking rec-
ognize as being solid or broken. Before this, a
warning must be given by means of intermit-
tent vibration in the steering wheel. In addi-
tion, a lane with lane markings on both sides must be recognized.
In the case of a broken lane marking being
detected, a lane-correcting brake application can only be made if a vehicle has been detec-
ted in the adjacent lane. Oncoming vehicles,
overtaking vehicles and vehicles in adjacent
lanes can be detected.
i A further lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane.
No lane-correcting brake application occurs
if:
R you clearly and actively steer, brake or
accelerate.
R you cut the corner on a sharp bend.
R you have switched on the turn signal.
R a driving safety system intervenes, e.g.
ESP ®
, PRE-SAFE ®
Brake or Active Blind
Spot Assist. R
you have adopted a sporty driving style with
high cornering speeds or high rates of
acceleration.
R ESP ®
is switched off.
R the transmission is not in position D.
R a loss of tire pressure or a defective tire has
been detected and displayed.
R an obstacle in the lane in which you are
driving has been detected.
Active Lane Keeping Assist may not detect
other road users or traffic situations. An inap- propriate brake application may be interrup-
ted at any time if you:
R steer slightly in the opposite direction
R switch on the turn signal
R clearly brake or accelerate
A lane-correcting brake application is inter-
rupted automatically if:
R a driving safety system intervenes, e.g.
ESP ®
, PRE-SAFE ®
Brake or Active Blind
Spot Assist.
R lane markings can no longer be recognized.
