Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 210) and Lane Keeping
Assist (Y page 211).
Blind Spot Assist General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sen-
sors. A warning lamp lights up on the exterior
mirror and draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lanes, you will also receive a visual and
audible warning.
Blind Spot Assist supports you from a speed of
approximately 30 km/h.
Important safety notes G
WARNING
Blind Spot Assist does not react to vehicles:
R overtaken too closely on the side, placing
them in the blind spot area
R when the difference in the speed of
approach and overtaking is too great
As a result, Blind Spot Assist cannot warn
drivers in these situations. There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and maintain a safe distance at the side
of the vehicle.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is not a substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.
Radar sensors The radar sensors for Blind Spot Assist are inte-
grated into the rear bumper. Make sure that the
bumpers are free of dirt, ice and slush. The sen- sors must not be covered, e.g. by cycle racks oroverhanging loads. Following a severe impact or in the event of damage to the bumpers, have the
function of the radar sensors checked at a quali- fied specialist workshop. Blind Spot Assist may
no longer work properly in such cases.
Monitoring range In particular, the detection of obstacles can be
impaired in the case of:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to fog, heavy rain,
snow or spray
R narrow vehicles, e.g. motorcycles or bicycles
R very wide lanes
R narrow lanes
R vehicles not driving in the middle of their lane
R crash barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated. At a distance of around 0.5 m
;from the vehi-
cle, Blind Spot Assist monitors the area up to
3.0 mnext to =and behind :your vehicle, as
shown in the picture.
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 driv-
ing in the middle of their lane. This may be the
case if the vehicles are driving on the inner side of their lane.
Due to the nature of the system:
R warnings may be issued in error when driving
close to crash barriers or similar solid boun-
daries
R warnings may be interrupted when driving
alongside long vehicles, e.g. lorries, for a pro-
longed time 210

Warning lamp
:
Warning lamp
Blind Spot Assist is not active at speeds below
approximately 30 km/h. Vehicles in the moni-
toring range are then not indicated.
If a vehicle is detected within the blind spot
monitoring range at speeds above approx-
imately 30 km/h, warning lamp :on the cor-
responding side lights up red. This warning lamp always lights up when a vehicle enters the blindspot monitoring range from behind or from the
side. When you overtake a vehicle, the warning
occurs only if the difference in speed is less than
12 km/h.
If you select reverse gear, Blind Spot Assist is
not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
Collision warning
If a vehicle is detected in the blind spot moni-
toring range and you switch on the correspond-
ing turn signal, a double warning tone sounds.
The red warning lamp flashes on the relevant
exterior mirror. If the turn signal remains on,
detected vehicles are indicated by the flashing
of the red warning lamp on the exterior mirror.
There are no further warning tones.
Activating Blind Spot Assist
X Make sure that Blind Spot Assist is activated
in the on-board computer (Y page 241).
X Turn the key to position 2in the ignition lock.
The red warning lamps on the exterior mirrors
light up until the engine is started. Display in the Assist image
When Blind Spot Assist is activated, grey radar
waves propagating backwards appear next to
the vehicle in the Assist image on the multifunc-
tion display (Y page 239). Above a speed of
30 km/h, the colour of the radar waves in the
Assist image changes to green :. Blind Spot
Assist is then ready for use.
Towing a trailer
If you couple up a trailer, make sure that you
have correctly established the electrical con-
nection. This can be accomplished by checking
the trailer lighting. Blind Spot Assist is then
deactivated. The Blind Spot Assist not Blind Spot Assist not

Lane Keeping Assist General notes
Lane Keeping Assist monitors the area in front of
your vehicle by means of multifunction cam-
era :attached at the top of the windscreen.
Lane Keeping Assist detects lane markings on
the road and can warn you before you leave your lane unintentionally. Driving systems
211Driving and parking Z

This function is available in a speed range
between 60 km/h and 200 km/h.
A warning may be given if a front wheel passes
over a lane marking. It will warn you by means of intermittent vibration through the steering
wheel for up to 1.5 seconds.
Important safety notes G
WARNING
Lane Keeping Assist cannot always clearly
identify lane markings.
In these cases, Lane Keeping Assist may:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep in lane, especially if Lane
Keeping Assist alerts you. G
WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is a risk of an accident.
Always steer, apply the brakes or accelerate
the vehicle yourself, especially if Lane Keep-
ing Assist alerts you.
Lane Keeping Assist can neither reduce the risk
of an accident if you fail to adapt your driving
style nor override the laws of physics. Lane
Keeping Assist cannot take into account road,
weather or traffic conditions. 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
lane.
Lane Keeping Assist does not keep your vehicle in its lane.
The system may be impaired or may not function
in the following situations:
R poor visibility, e.g. due to insufficient illumi-
nation of the road, or due to snow, rain, fog or
spray
R glare, e.g. from oncoming traffic, the sun or
reflection from other vehicles (e.g. if the road
surface is wet)
R the windscreen is dirty, misted up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera R
no or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area
R the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
R the distance to the vehicle in front is so small
that the lane markings cannot be detected
R the lane markings change quickly, e.g. lanes
branch off, cross one another or merge
R the road is very narrow and winding
R there are highly variable shade conditions on
the road surface

General notes The Driving Assistance PLUS package consists
of DISTRONIC PLUS (Y page 178), Active Blind
Spot Assist (Y page 213) and Active Lane Keep-
ing Assist (Y page 216).
Active Blind Spot Assist General notes
Using two lateral, rear-facing radar sensors,
Active Blind Spot Assist monitors the areas on
either side of the vehicle that are not visible to
the driver. A warning lamp lights up on the exte- rior mirrors and draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lanes, you will also receive a visual and
audible warning. If a risk of side impact is detec- ted, a course-corrective brake application may
help you avoid a collision. Active Blind Spot
Assist evaluates the free space in the direction
of travel and to the side before making a course-correcting brake application. For this, Active
Blind Spot Assist uses the forward-facing radar
sensors.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
Important safety notes Active Blind Spot Assist is only an aid and is not
a substitute for attentive driving. G
WARNING
Active Blind Spot Assist does not react to
vehicles:
R overtaking too closely on the side, placing
them in the blind spot area
R if the difference in the speed of approach
and overtaking is too great
As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and maintain a safe distance at the side of the vehicle.
Radar sensors
The Active Blind Spot Assist radar sensors are
integrated in the front and rear bumpers and
behind a cover in the radiator trim. Make sure
that the bumpers and the cover in the radiator
trim are free of dirt, ice or slush. The rear sen-
sors must not be covered, e.g. by bicycle racks
or overhanging loads. Following a severe impact or in the event of damage to the bumpers, have
the function of the radar sensors checked at a
qualified specialist workshop. Active Blind Spot
Assist might otherwise no longer function prop-
erly. Driving systems
