Important safety notes
GWARNING
Lane Keepin g Assist may not always clearly
recognize lane markings.
In this case, Lane Keepin g Assist may:
Rgive an unnecessary warning
Rnot give a warning
There isa risk of an acc ident.
Always pay particular attention to the traff ic
situation and stay inlane, inparticular if
warned byLane Keepin g Assist.
GWARNING
The Lane Keepin g Assist warning does not
return the veh icleto the original lane. There is
a risk of an acc ident.
You should always steer, brake or accelerate
yourself, inparticular ifwarned byLane Keep-
ing Assist.
If you fail to adapt your driving style, Lane
Keeping Assist can neither reduce the risk of
an accident nor override the laws of physics.
Lane Keeping Assist cannot take into account
the road, traffic and weather conditions. Lane
Keeping Assist is merely 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.
The Lane Keeping Assist does not keep the
vehicle in the lane.
The system may be impaired or may not func- tion if:
Rthere is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray
Rthere is glare, e.g. from oncoming traffic,
the sun or reflections (e.g. when the road
surface is wet)
Rthe windshield is dirty, fogged up, damagedor covered, for instance by a sticker, in the
vicinity of the camera
Rthere are no, several or unclear lane mark-
ings for a lane, e.g. in areas with road con-
struction work
Rthe lane markings are worn away, dark or
covered up, e.g. by dir
t or snow
Rthe distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
Rthe lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
Rthe road is narrow and winding
Rthere are strong shadows cast on the road

Active Driving Assistance package
General notes
The Active Driving Assistance package con-
sists of DISTRONIC PLUS (
Ypage 156), Active
Blind Spot Assist (
Ypage 180) and Active
Lane Keeping Assist (
Ypage 183).
Active Blind Spot Assist
General notes
Active Blind Spot Assist uses a radar sensor
system, pointed toward the rear of the vehi-
cle, to monitor the area to the sides of the
vehicle which the driver is unable to see. A
warning display in the exterior mirrors draws
your attention to vehicles detected in the
monitored area. If you then switch on the cor-
responding turn signal to change lanes, you
will also receive a visual and audible collision
warning. If a risk of lateral collision is detec-
ted, corrective braking may help you avoid a
collision. Before a course-correcting brake
application, Active Blind Spot Assist evalu-
ates the space in the direction of travel and at
the sides of the vehicle. For this, Active Blind
Spot Assist uses the forward-facing radar
sensors.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
180Driving systems
Driving and parking

The detection of obstacles can be impaired in
the case of:
Rthere is dirt on the sensors or anything else
covering the sensors
Rpoor visibility, e.g. due to rain, snow or
spray
Vehicles in the monitoring range are then not indicated or indicated with a delay.
Active Blind Spot Assist may not detect nar-
row vehicles, such as motorcycles or bicy-
cles, or may only detect them too late.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may be
the case if there are vehicles at the edge of
their lane.
Due to the nature of the system:
Rwarnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders.
Rthe warning is canceled when driving for an
extended period next to long vehicles, such
as trucks.
Warning display
:Warning display
Active Blind Spot Assist is not active at
speeds below approximately 20 mph
(30 km/h). Vehicles in the monitoring range
are then not indicated.
When Active Blind Spot Assist is activated,
indicator lamp :in the exterior mirrors lights
up yellow at speeds of up to 20 mph
(30 km/h). At speeds above 20 mph (30 km/h), the indicator lamp goes out and
Active Blind Spot Assist is operational.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp :on the corre-
sponding side lights up red. This warning is
always given when a vehicle enters the blind
spot monitoring range from behind or from
the side. When you overtake a vehicle, the
warning only occurs if the difference in speed
is less than 7 mph (12 km/h).
The yellow indicator lamp goes out if reverse
gear is engaged. Active Blind Spot Assist is
not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the
surroundings.
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, detec-
ted vehicles are indicated by the flashing of
red warning lamp :. There are no further
warning tones.
Course-correcting brake application
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.
GWARNING
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 appli-
cation. Always maintain a safe distance at the
sides.
182Driving systems
Driving and parking

Example: Sedan
If a course-correcting brake application
occurs, red warning lamp:flashes in the
exterior mirror and a dual warning tone
sounds. In addition, display ;appears in the
multifunction display underlining the danger
of a side collision.
In very rare cases, the system may make an
inappropriate brake application. An inappro-
priate course-correcting brake application
may be interrupted at any time if you steer
slightly in the opposite direction or acceler-
ate, 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:
Rthere are vehicles or obstacles, e.g. crash
barriers, located on both sides of your vehi-
cle.
Ra vehicle approaches you too closely at the
side.
Ryou have adopted a sporty driving style with
high cornering speeds.
Ryou clearly brake or accelerate.
Ra driving safety system intervenes, e.g.
ESP®or PRE-SAFE®Brake.
RESP®is switched off.
Ra loss of tire pressure or a defective tire is
detected.

RSwitching on Active Blind Spot Assist
Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the area
in front of your vehicle by means of multi-
function camera :at the top of the wind-
shield. Various different areas to the front,
rear and side of your vehicle are also moni-
tored 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-cor-
recting 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).

there is sufficient distance on the side for
other traffic or obstacles.
Example: Sedan
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.
If a lane-correcting brake application occurs,
display:appears in the multifunction dis-
play.
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. The following vehi-
cles can have an influence on brake applica-
tion: oncoming traffic, vehicles that are over-
taking and vehicles that are driving parallel to
your vehicle.
iA 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:
Ryou clearly and actively steer, brake or
accelerate.
Ryou cut the corner on a sharp bend.
Ryou have adopted a sporty driving style with
high cornering speeds or high rates of
acceleration.
Ryou have switched on the turn signals.
Ra driving safety system intervenes, e.g.
ESP®, PRE-SAFE®Brake or Active Blind
Spot Assist.
RESP®is switched off.
Rthe transmission is not in position D.
Ran obstacle has been detected in the lane in
which you are driving.
Rwhen a loss of tire pressure or a defective
tire has been detected and displayed.
There is a possibility that the Active Lane
Keeping Assist could misjudge the given traf-
fic situation. An inappropriate brake applica-
tion may be interrupted at any time if you:
Rsteer slightly in the opposite direction
Rswitch on the turn signal
Rclearly brake or accelerate
A lane-correcting brake application is inter-
rupted automatically if:
Ra driving safety system intervenes, e.g.
ESP®, PRE-SAFE®Brake or Active Blind
Spot Assist.
Rlane markings can no longer be recognized.
