2014 MERCEDES-BENZ E-SEDAN lane assist

The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.
Visual and acoustic collision warning
If you switch on the turn signals to change
lanes and a vehicle is detected in the side
monitoring range, you receive a visual and
acoustic collision warning. You then hear a
double warning tone and red warning
lamp :flashes. If the turn signal remains on,
detected vehicles are indicated by the
flashing of red warning lamp :. There are no
further warning tones.
Course-correcting brake application G
WARNING
A course-correcting brake application cannot
always prevent a collision. There is a risk of
an accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake
application. Always maintain a safe distance
at the sides. If Active Blind Spot Assist detects a risk of a
lateral collision in the monitoring range, a
course-correcting brake application is carried
out. This is meant to assist you in avoiding a
collision.
If a course-correcting brake application
occurs, red warning lamp
:flashes in the
exterior mirror and a dual warning tone
sounds. In addition, ;appears in the
multifunction display.
In very rare cases, the system may make an
inappropriate brake application. An
inappropriate course-correcting brake
application may be interrupted at any time if
you steer slightly in the opposite direction or
accelerate, for example.
The course-correcting brake application is
available in the speed range between
20 mph (30 km/h) and 120 mph (200 km/h).
Either no braking application, or a course-
correcting brake application adapted to the
driving situation occurs if:
R there are vehicles or obstacles, e.g. crash
barriers, located on both sides of your
vehicle.
R a vehicle approaches you too closely at the
side.
R you have adopted a sporty driving style with
high cornering speeds.
R you clearly brake or accelerate.
R a driving safety system intervenes, e.g.
ESP ®
or PRE-SAFE ®
Brake.
R ESP ®
is switched off.
R a loss of tire pressure or a defective tire is
detected.

Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the area
in front of your vehicle by means of camera
system :at the top of the windshield.
Various different areas to the front, rear and
side of your vehicle are also monitored with
the aid of the radar sensor system. Active
Lane Keeping Assist detects lane markings on
the road and can warn you before you leave
your lane unintentionally. If you do not react
to the warning, a lane-correcting application
of the brakes can bring the vehicle back into
the original lane.
This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
For Active Lane Keeping Assist to assist you
when driving, the radar sensor system must
be operational
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
physics. 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
continuously 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.
Terminate the intervention in a non-critical
driving situation.
The system may be impaired or may not
function if:
R there is poor visibility, e.g. due to
insufficient 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
bumpers or the radiator grill are dirty, e.g.
obscured by snow
R there are no, several or unclear lane
markings for a lane, e.g. in areas with road
construction 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 lane Driving systems

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
steering wheel for up to 1.5 seconds.
Lane-correcting brake application 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
application. G
WARNING
Active Lane Keeping Assist only detects
traffic conditions or road users to a limited
extent. In very rare cases, the system may
make an inappropriate brake application, e.g.
after intentionally driving over a solid lane
marking. There is a risk of an accident.
An inappropriate brake application may be
interrupted at any time if you steer slightly in
the opposite direction. Always make sure that
there is sufficient distance on the side for
other traffic or obstacles. If you leave your lane, under certain
circumstances the vehicle will brake briefly on one side. This is meant to assist you in
bringing the vehicle back to the original lane.
If a lane-correcting brake application occurs,
display
:appears in the multifunction
display.
A lane-correcting brake application can be
made after driving over a lane marking
recognize as being solid or broken. Before
this, a warning must be given by means of
intermittent vibration in the steering wheel.
In addition, 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
detected in the adjacent lane. The following
vehicles can have an influence on brake
application: oncoming traffic, vehicles that
are overtaking and vehicles that are driving
parallel to your vehicle.
i A further lane-correcting brake
application 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 adopted a sporty driving style with
high cornering speeds or high rates of
acceleration.
R you have switched on the turn signals.
R a driving safety system intervenes, e.g.
ESP ®
, PRE-SAFE ®
Brake or Active Blind
Spot Assist.
R ESP ®
is switched off.
R the transmission is not in position D.
R an obstacle has been detected in the lane
in which you are driving.
R a loss of tire pressure or a defective tire has
been detected and displayed.
There is a possibility that the Active Lane
Assistant could misjudge the given traffic 234
