assessing your tiredness again when you con-
tinue your journey if:
R you switch off the engine.
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break. Speed Limit Assist
Important safety notes Speed Limit Assist shows you detected speed
limits in the multifunction display. Data from
the navigation system is also used for this
purpose. If a traffic sign indicating a speed
limit or the end of a speed limit is detected,
it is shown in the multifunction display. If
Speed Limit Assist does not detec tany traffic
signs, the speed limit from the digital road
map is take nand shown in the display.
Speed Limit Assist detects the traffic signs
with a camera attached behind the top of the
windscreen. :

Important safety notes In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road. The
Night View Assist Plus camera picks up the
infrared light and displays
amonochrome
image in COMAND. The image displayed in
COMAND corresponds to a road lit up by
main-beam headlamps. This enables you to
see the road's course and any obstacles in
good time. When pedestrian recognition is
active, pedestrians recognised by the system
are highlighted in the Night View Assist Plus
display. G
WARNING
Night View Assist Plus is only an aid designed
to assist driving and does not relieve you of
the responsibility to pay attention. Continue
to look through the windscreen instead of
relying on the Night View Assist Plus display.

also the case if you cannot switch on the
main-beam headlamps due to oncoming traf-
fic. G
WARNING
Night View Assist Plus does not detect
objects in the immediate vicinity of the vehi-
cle. Look through the windscreen when
manoeuvring. Make sure that there are no
people or animals in the area in which you are
manoeuvring.
i Infrared light is not visible to the human
eye and therefore does not dazzle. Night
View Assist Plus can therefore remain
switched on even if there is oncoming traf-
fic. :

Pedestrian recognition G
WARNING
Pedestrian recognition may be impaired or
inoperative if:
R pedestrians are partially or entirely
obscured by objects, e.g. by parked vehi-
cles.
R the silhouette of the pedestrian in the Night
View Assist Plus display is incomplete or
interrupted, e.g. by powerful light reflec-
tions.
R pedestrians do not contrast with the sur-
roundings.
R pedestrians are not in an upright position,
e.g. sitting, squatting or lying.
i Animals are not recognised by pedestrian
recognition.
Night View Assist Plus can recognise pedes-
trians using typical characteristics, e.g. when
there is a silhouette in the shape of a person.
Pedestrian recognition is then switched on
automatically if:
R Night View Assist Plus is activated.
R you are driving faster than about 10 km/h.
R the surroundings are dark, e.g .when driv-
ing outside built-up areas without street
lighting.
If pedestrian recognition is active, sym-
bol ?appears. If a pedestrian is now recog-
nised, they are framed =and thereby high-
lighted. If the pedestrian recognition system
has brought a pedestrian to your attention,
look through the windscreen to evaluate the
situation. The actual distance to objects and
pedestrians cannot be gauged accurately by
looking at a screen.
It may be the case that objects are highlighted
as well as pedestrians. Misted up or dirty windscreen If the windscreen in front of the camera is

General notes The Lane Tracking package consists of Blind
Spot Assist (Y
page 212) and Lane Keeping
Assist (Y page 214).
Blind Spot Assist Important safety notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from speeds of
30 km/h. A warning display in the exterior
mirrors draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lane, you will also receive an optical
and audible collision warning. For monitoring,
Active Blind Spot Assist uses sensors in the
rear bumper. G
WARNING
Blind Spot Assist is only an aid designed to
assist driving. It may fail to detect some vehi-
cles and is no substitute for attentive driving.
Blind Spot Assist cannot detect road and traf-
fic conditions. It may fail to detect narrow
vehicles, such as motorcycles or bicycles, or
only detect them too late.
Monitoring may be affected by dirty sensors,
strong spray or poor visibility caused by snow,
rain or mist, for example. In this case, vehicles
are detected late or not at all.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.
The radar sensor system is automatically
deactivated near radio telescope facilities
(Y page 398).
For Blind Spot Assist to assist you when driv-
ing, the radar sensor system must be activa-
ted (Y page 247) and operational. 212
Driving systemsDriving and parking
Page 216 of 409
Monitoring range of the sensors
Blind Spot Assist monitors the area up to
three metres behind yourv ehicle and directly
nextt o your vehicle, as shown in the diagram. Example: Saloon
G
WARNING
Blind Spot Assist monitors certain areas in the
immediate vicinity of your vehicle. Vehicles
that approach and drive past at high speeds
are not detected. There is no display and no
warning.
If the lanes are very wide, it may not be pos-
sible to monitor the complete width of the
neighbouring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in a staggered formation in
different lanes. This may be the case if vehi-
cles are driving at the edge of their lane that
is furthest away from your vehicle.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.
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 nearest your vehicle. Due to the nature of the system:
R
warnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders.
R warnings may be interrupted when driving
alongside long vehicles, for example lor-
ries, for a prolonged time.
The two radar sensors for Blind Spot Assist
are integrated into the sides of the rear
bumper. Make sure that the bumper is free of
dirt, ice or slush in the vicinity of the sensors.
The sensors must not be covered, for exam-
ple by cycle racks or overhanging loads. Fol-
lowing a severe impact or in the event of dam-
age to the bumpers, have the function of the
sensors checked at a qualified specialist
workshop. Blind Spot Assist may otherwise
not work properly.
Indicator and warning display :
Yellow indicator lamp/red warning lamp
If Blind Spot Assist is switched on, indicator
lamp :in the exterior mirrors lights up yel-
low up to a speed of 30 km/h. At speeds
above 30 km/h, the indicator lamp goes out
and Blind Spot Assist is operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp :on the corre-
sponding side lights up red. This warning is
always emitted 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 12 km/h. Driving systems
213Driving and parking Z
Page 217 of 409
The yellow indicator lamp goes out if reverse
gear is engaged. Blind Spot Assist is then
deactivated.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.
G
WARNING
Blind Spot Assist is not active at speeds below
30 km/h. The indicator lamps in the exterior
mirrors are yellow. Vehicles in the monitoring
range are then not indicated.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.
Collision warning
If a vehicle is detected in the monitoring range
of Blind Spot Assist and you switch on the
corresponding turn signal, a double warning
tone sounds. 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.
Switching on Blind Spot Assist
X Make sure that the radar sensor system
(Y page 247) and Blind Spot Assist
(Y page 242) are activated in the on-board
computer.
X Turn the key to position 2in the ignition
lock.
Warning lamps :light up red in the exte-
rior mirrors for approximately 1.5 seconds
and then turn yellow.
Trailer towing
If you attach a trailer, make sure that you have
correctly established the electrical connec-
tion. This can be accomplished by checking
the trailer lighting. Blind Spot Assist is then
deactivated. The indicator lamp in the exte-
rior mirrors lights up yellow, and the BlindSpot Assist currently unavailable
See Owner's Manual message appears in
the multifunction display. i
You can deactivate the indicator lamps in
the exterior mirrors.
To do so, switch off Blind Spot Assist if:
R the key is in position 2in the ignition
lock.
R the engine is not running.
R the electrical connection to the trailer
has been established.
Lane Keeping Assist Important safety notes
Lane Keeping Assist monitors the area in
front of your vehicle by means of a camera at
the top of the windscreen. Lane Keeping
Assist detects lane markings on the road and
warns you before you leave your lane unin-
tentionally. :
Lane Keeping Assist camera
If you have chosen the Display unit Speed-/odometer (Y
page 243) function in
the on-board computer and select km as the
unit of measurement, Lane Keeping Assist is
active from speeds of 60 km/h. If the miles display unit is selected, the assistance range
begins at 40 mph.
G
WARNING
Lane Keeping Assist does not keep your vehi-
cle in its lane. It is only an aid and may detect
the lane markings on the road incorrectly or
not at all. 214
Driving systemsDriving and parking
Page 218 of 409
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 reflection from other vehicles.
R the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera
R several or no lane markings for a single lane
are present.
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 on the road are unclear,
e.g. near roadworks.
R the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge.
R the road is narrow and winding.
Lane Keeping Assist cannot detect road and
traffic conditions. It is not a substitute for
attentive driving. You are responsible for the
vehicle's speed, braking in good time, and
steering correctly. Always adapt your driving
style to suit the prevailing road and weather
conditions. Always pay attention to traffic
conditions and your surroundings. Otherwise,
you may fail to recognise dangers in time,
cause an accident and injure yourself and oth-
ers.
A warning may be given if a front wheel
passes over a lane marking .Itwill warn you
by means of intermittent vibration in the
steering wheel for up to 1. 5seconds.
In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system recognises certain con-
ditions and warns you accordingly. The warning vibration occurs earlier if:
R
you approach the outer lane marking on a
bend.
R the road has very wide lanes, e.g. a motor-
way.
R the system recognises solid lane markings.
The warning vibration occurs later if:
R the road has narrow lanes.
R you cut the corner on a bend.
No warning vibration occurs if:
R you clearly and actively steer, brake, or
accelerate.
R you cut the corner on a sharp bend.
R a driving safety system intervenes, such as
ABS, BAS or ESP ®
.
R you have switched on the turn signals. In
this event, the warnings are suppressed for
a certain period of time.

Active Blind Spot Assist Important safety notes
Active Blind Spot Assist uses a radar sensor
system to monitor the side areas of your vehi-
cle which are behind the driver.
Awarning
display in the exterior mirrors draws your
attentio nto vehicles detected in the moni-
tored area. If you then switch on the corre-
sponding turn signal to change lane, 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 30 km/h. G
WARNING
Active Blind Spot Assist is only an aid and may
detect vehicles/obstacles incorrectly or not
at all.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to snow,
rain, fog or spray.
R the rear and/or front sensors are dirty.
Active Blind Spot Assist may not detect nar-
row vehicles, such as motorcycles or bicycles,
or only detect them too late. It cannot detect
vehicles which are overtaken at a small dis-
tance and then enter the blind spot area.
Active Blind Spot Assist cannot detect road
and traffic conditions. It is not a substitute for
attentive driving. You are responsible for the
vehicle's speed, braking in good time, and
steering correctly. Always adapt your driving
style to suit the prevailing road and weather
conditions. Always pay attention to traffic
conditions and your surroundings. Otherwise,
you may fail to recognise dangers in time,
cause an accident and injure yourself and oth-
ers. The radar sensor system is automatically
deactivated near radio telescope facilities
(Y
page 398).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be activated (Y page 247) and operational.
Monitoring range
Active Blind Spot Assist monitors the area up
to three metres behind your vehicle and
directly next to your vehicle as shown in the
diagram. For this purpose, Active Blind Spot
Assist uses radar sensors in the rear bumper. Example: Saloon
G
WARNING
Active Blind Spot Assist monitors certain
areas in the immediate vicinity of your vehicle.
Vehicles that approach and drive past at high
speeds are not detected. No visual nor audi-
ble warnings are emitted and the system does
not brake the vehicle to correct your course.
If the lanes are very wide, it may not be pos-
sible to monitor the complete width of the
neighbouring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in a staggered formation.
This may be the case if vehicles are driving at
the edge of their lane that is furthest away
from your vehicle. 216

Two Active Blind Spot Assist radar sensors
are integrated into the front and rear bumpers
respectively. An additional radar sensor is
located behind the cover in the radiator grille.
Make sure that the sensors and the areas
around them are free of dirt, ice or slush. The
rear sensors 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 sensors
checked at a qualified specialist workshop.
Blind Spot Assist may otherwise not work
properly.
Indicator and warning display :

When Active Blind Spot Assist is activated,
indicator lamp :in the exterior mirrors lights up yellow at speeds of up to 30 km/h. At
speeds above 30 km/h, the indicator lamp
goes out and Active Blind Spot Assist is
operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp
:on the corre-
sponding side lights up red. This warning
always occurs 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 12km/h.
The yellow indicator lamp goes out if reverse
gear is engaged. Active Blind Spot Assist is
then no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light. G
WARNING
Active Blind Spot Assist is not active at speeds
below 30 km/h. The indicator lamps in the
exterior mirrors are yellow .Vehicles in the
monitoring range are then not indicated.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time and cause an acci-
dent and injure yourself and others.
Visual and acoustic collision warning
If a vehicle is detected in the side monitoring
range and you switch on the appropriate turn
signals, you will receive a collision warning.
You will 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
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 designed to help you avoid a col-
lision. Driving systems
