Important safety notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 80 km/h
to 180 km/h range.
If ATTENTION ASSIST detects typical indica-
tors of fatigue or increasing lapses in con-
centration on the part of the driver, it sug-
gests taking 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 asubstitute
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 acciden tand

Important safety notes 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
could otherwise endanger yourself and oth-
ers. 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 windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera.
R on bends, on uphill gradients or downhill
gradients.
Light from the headlamps of oncoming vehi-
cles does not affect the Night View Assist Plus
display in the multifunction display. This is
also the case if you cannot switch on the
main-beam headlamps because of oncoming
traffic. G
Risk of accident
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. :

General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 183) and Lane Keeping
Assist (Y page 185).
Blind Spot Assist Important safety notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. Blind Spot Assist provides assistance
at speeds higher than 30 km/h. A warning
lamp in the exterior mirrors draws your atten-
tion to detected vehicles in the monitored
area. If you then switch on the corresponding
turn signal to change lane, you will also
receive an optical and acoustic collision warn-
ing. For this purpose, Blind Spot Assist uses
sensors in the rear bumper. G
Risk of accident
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 327).
For Blind Spot Assist to assist you when driv-
ing, the radar sensor system must be
switched on (Y page 210) and operational. Driving systems
183Driving and parking Z
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. 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. In particu-
lar, this may be the case if the vehicles are driving 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 particularly long vehicles for a
prolonged time.
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. 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 in red. This warning is
always emitted when a vehicle enters the
blind spot monitoring range from behind or 184

attentive driving. You are responsible for the
vehicle's speed, braking in good time, and
steering correctly. Always adapt yourd riving
style to suitt he 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 can be 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.
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.

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. In addition, it uses the radar sensor sys-
tem to monitor the front area as well. Active
Blind Spot Assist provides assistance at
speeds higher than about 30 km/h. Awarn-
ing lamp in the exterior mirror calls your
attentio nto a vehicle or certain obstacles
detected in the area monitored. If you then
switch on the corresponding turn signal to
change lane, you will also receive an optical
and acoustic collision warning. If a risk of lat-
eral collision is detected, corrective braking
may help you avoid a collision. 186
