General 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.
ATTENTION ASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
R your personal driving style, e.g. steering
characteristics
R journey-related parameters, e.g. time of
day, length of journey
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or
not occur at all:
R if the road condition is poor, e.g. if the sur-
face is uneven or if there are potholes
R if there is a strong side wind
R if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R if you are predominantly driving slower
than 80 km/h or faster than 180 km/h
R if you are currently using COMAND Online
or making a telephone call with COMAND

using COMAND Online. The maximum per-
missible speed is shown in the COMAND
display; see the COMAND Online operating instructions. Night View Assist Plus
Important safety notes Night View Assist Plus is only an aid and is not
a substitute for attentive driving. Do not rely
on the Night View Assist Plus display. You areresponsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Drive carefully and always adapt
your driving style to suit the prevailing road
and traffic conditions.
Night View Assist Plus cannot display objects
directly in front of or beside the vehicle.
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
Pedestrian recognition may be impaired or
inoperative if:
R pedestrians are partially or entirely
obscured by objects, e.g. parked vehicles
R the silhouette of the pedestrian in the Night
View Assist Plus display is incomplete or
interrupted, e.g. by powerful light reflec-
tions 220

R
pedestrians do not contrast with the sur-
roundings
R pedestrians are not in an upright position,
e.g. sitting, squatting or lying 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
main-beam headlamps due to oncoming traf-
fic.
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. Activating Night View Assist Plus Activation conditions
You can only activate Night View Assist Plus
if:
R the key is in position 2in the ignition lock
R it is dark
R the light switch is in the ÃorL posi-
tion
R reverse gear has not been engaged
Activating Night View Assist Plus X
Make sure COMAND Online is switched on.
X Press button :.
The Night View Assist Plus display appears in the COMAND display.
You can read about how to adjust the bright- ness of the COMAND display in the COMAND
Online operating instructions.
i The infrared headlamps only switch on
when the vehicle is being driven at speeds
of at least 10 km/h. This means that you do
not have the full visual range while station-
ary and cannot check whether Night View
Assist Plus is working. Driving systems

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 switched on auto-
matically if:
R Night View Assist Plus is activated.
R you are driving faster than 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, symbol ?
appears. If pedestrians are detected, they are highlighted with framing =. If the pedestrian
recognition system has brought a pedestrian
to your attention, look through the wind-
screen 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
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 147) and fold down
the camera cover (Y page 339).
X To demist the inside of the windscreen:
fold down the camera cover (Y page 339)

Monitoring range of the sensors
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 bicy-
cles
R very wide lanes
R narrow lanes
R vehicles not driving in the middle of their
lane
R barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated. CLS Coupé
Blind Spot Assist monitors the area up to
3.0 mbehind your vehicle and directly next to
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 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.

Example: CLS Coupé
If Active Blind Spot Assist detects a risk of a
side impact in the monitoring range, a course-correcting brake application is carried out.
This is designed to help you avoid a collision.
If a course-correcting brake application
occurs, red warning lamp :flashes in the
exterior mirror and a dual warning tone
sounds. In addition, the display shown in the
lower image appears in the multifunction dis- play.
In very rare cases, the system may make an
inappropriate brake application. A course-
correcting brake application may be interrup-
ted at any time if you steer slightly in the
opposite direction or accelerate.
The course-correcting brake application is
available in the speed range between
30 km/h and 200 km/h.
Either a course-correcting brake application
appropriate to the driving situation, or none at all, may occur if:
R there are vehicles or obstacles, e.g. crash
barriers, on both sides of your vehicle
R a vehicle approaches too closely on the
side
R you have adopted a sporty driving style with
high cornering speeds R
you clearly brake or accelerate
R a driving safety system intervenes, such as
