Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose.
Do not use the reversing camera in these
types of situation. You could, otherwise,
injure others or damage objects and your
vehicle while you are parking.
Activating the reversing camera X
Make sure that the key is in position 2in
the ignition lock.
X Make sure that the "Reversing camera"
function is selected in COMAND APS (see
the separate operating instructions for
COMAND APS).
X Engage reverse gear.
The area behind the vehicle is shown in the
COMAND APS display.
You can select not to show the area behind
the vehicle in the COMAND APS display (see
the separate operating instructions for
COMAND APS). ATTENTION ASSIST
ATTENTION ASSIST helps you on long, monot-
onous journeys such as on motorways and
trunk roads. It is active at speeds between 80
and 180 km/h. If ATTENTION ASSIST detects tiredness or increasing lapses in concentra-
tion on the part of the driver, it suggests a
break. G
Risk of accident
ATTENTION ASSIST is only an aid and may
detect your tiredness or lapses in concentra-
tion too late or not at all. It is not a substitute
for a well rested and attentive driver.
Fatigue may cause you to recognise hazard-
ous situations too late, misjudge a situation
or react slower. For this reason, make sure
you feel rested before you begin driving and
during your journey. Always take breaks in
good time and regularly, especially during
long journeys. Otherwise, you may fail to rec-
ognise dangers in time, cause an accident and
injure yourself and others.
ATTENTION ASSIST assesses your level of
fatigue or increasing inattentiveness taking
into consideration the following criteria:
R personal driving style, e.g. steering charac-
teristics
R driving conditions, e. g. time, driving time
ATTENTION ASSIST's functionality is restric-
ted and warnings are delayed or do not
appear at all:
R if the road condition is poor, e.g. large
bumps or potholes
R there is a strong side wind
R you have adopted a very sporty driving style
with high cornering speeds or driving with
a high rate of acceleration
R if you are predominantly driving slower
than 80 km/h or faster than 180 km/h
R if you are currently operating or making a
call using COMAND APS*
R in active driving situations, for example, if
you are changing lanes or changing the
vehicle speed Driving systems

secondary road).
R you have travelled a certain minimum
distance without the road sign being
repeated or detected again. Night View Assist Plus*
In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road. A
camera at the top of the windscreen picks up
the infrared light and displays a black and
white image in the COMAND APS display. The
image displayed in COMAND APS corre-
sponds to a road lit up by main-beam head-
lamps. This enables you to see the road's
course and any obstacles in good time. If
pedestrian recognition is activated, pedes-
trians recognised by the system are highligh-
ted in the Night View Assist Plus display. G
Risk of accident
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.
You are responsible for safety and must drive
in accordance with traffic conditions. You Driving systems

i
The infrared headlamps only switch on
when the vehicle is driving at speeds of at
least 10 km/h. This means that you do not
have the full visual range while stationary
and cannot check whether Night View
Assist Plus is working.
Pedestrian recognition The Night View Assist Plus recognises pedes-
trians using typical characteristics, i. e. a sil-
houette in the shape of a person.
Pedestrian recognition is activated, 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. G
Risk of accident
Pedestrian recognition may be impaired or
inoperative, if:
R pedestrians are partially or completely
obscured by objects, e. g. by parked vehi-
cles
R the silhouette in the Night View Assist Plus
display is incomplete or interrupted, e. g. by
powerful light reflections
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.
Misted up or dirty windscreen If the windscreen in front of the camera is
misted up or dirty on the inside or outside, the
Night View Assist Plus display is affected.
X To demist: check the automatic air-condi-
tioning settings (Y page 179) and fold
down the camera cover (Y page 245).
X To demist the inside of the wind-
screen: fold down the camera cover and
clean the windscreen (Y page 242). Lane package*
The lane package consists of Blind Spot
Assist and Lane Keeping Assist.
Blind Spot Assist Blind Spot Assist uses a radar sensor system
to monitor the area on both sides of your
vehicle. It supports you when you change
lanes at speeds above 30 km/h. In each case,
a warning lamp appears in the exterior mirror
as soon as a vehicle is detected in the area
monitored. When you switch on the corre-
sponding turn signal prior to changing lanes,
you receive an optical and acoustic collision
warning. For this purpose, Blind Spot Assist
uses sensors in the rear bumper.
G
Risk of accident
Blind Spot Assist is only an aid and may not
detect all vehicles. Blind Spot Assist does not
relieve you of the responsibility of paying
attention.
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 362). Driving systems

For Blind Spot Assist to help you when driving,
the radar sensor system must be switched on
and operational. G
Risk of accident
Blind Spot Assist cannot detect road and traf-
fic conditions.
Blind Spot Assist may not detect narrow vehi-
cles, 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.
Monitoring range of the sensors
Blind Spot Assist monitors the area up to
three metres behind your vehicle and directly
next to your vehicle as shown in the diagram. Example: Saloon
G
Risk of accident
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, the system may be
unable to distinguish the neighbouring lane
from the one beyond it. For this reason, vehi-
cles in the farther lane may be indicated,
especially if the vehicles are driving in a stag-
gered formation in different lanes. This may
be the case if vehicles are driving at the edge
of the lane that is nearest your vehicle. Due
to the nature of the system, warnings may be
issued in error when driving close to crash
barriers or similar solid lane borders.
The two sensors for Blind Spot Assist are
integrated into the sides of the rear bumper.
Make sure that the bumper is free from dirt,
ice or slush around the sensors. For example,
the radar sensors must not be covered by
cycle 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, e.g. a Mercedes-Benz Service
Centre. Otherwise, Blind Spot Assist may not
work properly. 168

Information and warning display
:
Yellow indicator lamp/red warning lamp
When you turn the key to position 2in the
ignition lock, warning lamps :in the exterior
mirrors light up red.
If Blind Spot Assist is switched on and the
engine is running, indicator lamps :in the
exterior mirrors light up yellow 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 issued 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.
The yellow indicator lamp goes out after
reverse gear is engaged. In this event, Blind
Spot Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light. G
Risk of accident
Blind Spot Assist is not active at speeds below
30 km/h, and the indicator lamps in the exte-
rior mirrors are yellow. Vehicles in the moni-
toring 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 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 134) and Blind Spot Assist
(Y page 130) are activated in the on-board
computer.
X Turn the key to position 2in the ignition
lock.
Red warning lamps :in the exterior mir-
rors are lit.
X Start the engine.
Warning lamps :in the exterior mirrors
now light up yellow.
Trailer towing*
Blind Spot Assist is deactivated when you
connect the trailer to your vehicle electrically.
The Blind Spot Assist currently
unavailable See Owner's Manual mes-
sage appears in the multi-function display.
Lane Keeping Assist If you select
kmon the on-board computer in
the Speed-/odometer: function
(Y page 131), Lane Keeping Assist is activa-
ted starting at a speed of 60 km/h. If the
miles display unit is selected, the assistance
range begins at between 35 and 40 mph.
Lane Keeping Assist is designed to detect
lane markings on the road and warn you
before you leave your lane unintentionally.
Usually the warning is given when 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. Driving systems

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 camera
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 occurs earlier if:
R you cut a corner on the outside.
R the road has very wide lanes, e.g. a motor-
way.
R the system recognises solid lane markings,
as crossing these often results in a critical
situation, e.g. in the case of hard shoulders
or crash barriers.
The warning occurs later if:
R the road has narrow lanes.
R you cut a corner on the inside.
No warning occurs if:
R you actively steer, brake or depress the
accelerator pedal, e.g. when changing lane,
overtaking, accelerating or leaving the
motorway.
R you cut the corner on a sharp bend.
R you drive around a very sharp bend.
R you switch on the turn signals. In this event
the warnings are suppressed for a certain
period of time.
R a driving safety system intervenes, such as
ABS, BAS or ESP ®
. G
Risk of accident
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.
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 there is glare, e.g. from the sun or from
oncoming traffic.
R the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera.
R there are no lane markings.
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
short.
R there are ambiguous lane markings on the
road, e.g. near roadworks.
R there are short-term changes to the mark-
ings, e.g. filter lanes or motorway exits.
R the road is narrow and winding.
Lane Keeping Assist cannot detect road and
traffic conditions. It is not a substitute for
attentive driving.
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.
