Important safety notes 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.
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. 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. In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road.
Night View Assist Plus camera
:picks up
the infrared light and displays a monochrome
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.
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 Driving systems

Monitoring range of the sensors
G
WARNING
Blind Spot Assist monitors certain areas in the
immediate vicinity of yourv ehicle. 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 nextl ane may no tbe detected, especially
if they are driving in a staggered formation in
differen tlanes .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. CLS Coupé
Blind Spot Assist monitors the area up to
3.0 mbehind your vehicle and directly nextto
your vehicle, as shown in the diagram.
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 barrier sorsimilar 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 bumpe ris 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.

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
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.

Lane-correcting brake application G
WARNING
Active Lane Keeping Assist does not keep
yourv ehicle in its lane. It is only an aid
designed to assist driving. It is not a substitute
for attentive driving. Corrective braking may
not always be sufficien tto return your vehicle
to its original lane. In such cases, you must
steer the vehicle yourself to ensure that it
does not leave the lane.
Active Lane Keeping Assist cannot detect the
current traffic situation or other road users.
Ensure at all times that there is sufficient lat-
eral distance between you and other road
users or obstacles. In rare cases, broken lines
or certain structures on the road surface may
be detected by the system as solid lane mark-
ings. You can, for example, countersteer gen- tly at any time to cancel inappropriate braking
action, e.g. if you intentionally drive across a
solid lane marking.
Active Lane Keeping Assist cannot take
weather conditions into account.
You are responsible for the vehicle's speed,
correc
tsteering and for braking in good time.
Always adap tyour 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 others. If a lane-correcting brake application occurs,
the display shown in the illustration appears
in the multifunction display.
If you leave your lane under certain circum-
stances, the vehicle will brake briefly on one
side. This is designed to help you bring the
vehicle back into the original lane.
This function is available in the range between
60 km/h and 200 km/h.
A lane-correcting brake application can only
be made after driving over a solid, recognis-
able lane marking. Before this, a warning
must be emitted by means of intermittent
vibration in the steering wheel. In addition, a
lane with lane markings on both sides must
be recognised. The brake application also
slightly reduces driving speed.
i A further lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane. 216
