Active Driving Assistance package
General notes
The Active Driving Assistance package con-
sists of DISTRONIC PLUS (
Ypage 182), Active
Blind Spot Assist (
Ypage 214) and Active
Lane Keeping Assist (
Ypage 217).
Active Blind Spot Assist
General notes
Active Blind Spot Assist uses a radar sensor
system to monitor the side areas of your vehi-
cle which are behind the driver. A warning
display in the exterior mirrors draws your
attention to vehicles detected in the moni-
tored area. If you then switch on the corre-
sponding turn signal to change lanes, you will
also receive an optical and audible collision
warning. If a risk of lateral collision is detec-
ted, corrective braking may help you avoid a collision. To support the course-correcting
brake application, Active Blind Spot Assist
also uses the forward-facing radar sensor sys-
tem.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be operational.
Important safety notes
Active Blind Spot Assist is only an aid. It may
fail to detect some vehicles and is no substi-
tute for attentive driving.
GWARNING
Active Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
214Driving systems
Driving and parking

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.
Rwarnings may be interrupted when driving
alongside particularly long vehicles, e.g.
trucks, for a prolonged time.
Indicator and warning display
:Yellow indicator lamp/red warning lamp
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. In this event, Active Blind
Spot Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light. Visual and acoustic collision warning
When 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 flash-
ing of red warning lamp :. There are no fur-
ther warning tones.
Course-correcting brake application
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.
216Driving system s
Driving an d parking

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.
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.
The course-correcting brake application is
available in the speed range between 20 mph (30 km/h) and 120 mph (200 km/h).
Either a very slight course-correcting brake
application, or none at all, may occur 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.
Switching on Active Blind Spot Assist
XMake sure that Active Blind Spot Assist is
activated (
Ypage 231).
XTurn the SmartKey to position 2in the igni-
tion lock.
Warning lamps :in the exterior mirrors
light up red for approximately 1.5 seconds
and then turn yellow.
Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the area
in front of your vehicle by means of camera :
at the top of the windshield. Active Lane
Keeping Assist detects lane markings on the
road and warns 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.
If you selectkm
on the on-board computer in
the Display Unit Speed-/Odometer
func-
tion (
Ypage 232), Active Lane Keeping Assist
is activated starting at a speed of 60 km/h. If
the miles
display unit is selected, the assis-
tance range begins at 40 mph.
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. Lane Keeping Assist cannot take into
account the road, traffic and weather condi-
tions. 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.
Active Lane Keeping Assist cannot continu-
ously keep your vehicle in its lane.
GWARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can:
Rgive an unnecessary warning and then
make a course-correcting brake application
to the vehicle
Rnot 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:
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, damaged or 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 dirt 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
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.
In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system recognizes certain con-
ditions and warns you accordingly.
The warning vibration occurs earlier if:
Ryou approach the outer lane marking on a
bend.
Rthe road has very wide lanes, e.g. a high-
way.
Rthe system recognizes solid lane markings.
The warning vibration occurs later if:
Rthe road has narrow lanes.
Ryou cut the corner on a bend.
Lane-correcting brake application
GWARNING
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,

A lane-correcting brake application can only
be made after driving over a solid, recogniz-
able lane marking. Before this, a warning must be given by means of intermittent vibra-
tion in the steering wheel. In addition, a lane
with lane markings on both sides must be
recognized. The brake application also
slightly reduces vehicle speed.
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 switched on the turn signals.
