Night View Assist Plus
General notes 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 the multifunction display. The image
shown in the display corresponds to a road lit
up by main-beam headlamps. This enables
you to see the road's course and any obsta-
cles in good time. When pedestrian recogni-
tion is active, pedestrians recognised by the
system are visually highlighted in colour in the Night View Assist Plus display with small
frame corners.
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.
In addition, thermal imaging camera :is
integrated in the radiator grille. The camera
helps detect pedestrians and animals.
Observe the notes on cleaning the thermal
imaging camera (Y page 349).
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 are responsible 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.
The system may be impaired or may not func-
tion:
R if there is poor visibility, e.g. due to snow,
rain, fog or spray
R if the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera
R if the thermal imaging camera in the radia-
tor grille is dirty, misted up or covered
R on bends, hilltops or downhill gradients
R at high outside temperatures
Night View Assist Plus cannot display objects directly in front of or beside the vehicle.
It may be the case that other objects are
marked or highlighted as well as pedestrians
and animals.
Pedestrian and animal recognition General notes
Pedestrian or animal recognition may be
impaired or inoperative if:
R pedestrians or animals are partially or
entirely obscured by other objects, e.g.
parked vehicles
R the silhouette of the pedestrian or of the
animal in the Night View Assist Plus display
is incomplete or interrupted, e.g. by pow-
erful light reflections
R pedestrians or animals do not contrast with
the surroundings
R the camera system no longer recognises
pedestrians as persons due to special
clothing or other objects
R pedestrians are not in an upright position,
e.g. sitting, squatting or lying
R animals are not recognised by the system,
e.g. because of their size or shape
The pedestrian and animal recognition is
deactivated at temperatures above 32 †. The spotlight function and automatic delayed
switch-off are then no longer active. 230

Problems with Night View Assist
Problem
Possible causes/consequences and
M
MSolutions The picture quality of
Night View Assist Plus
has deteriorated. The windscreen is misted up on the inside.
X Fold down the camera cover (Y page 349).
X Demist the windscreen (Y page 143). The windscreen is iced up.
X De-ice the windscreen (Y page 143). The windscreen wipers are smearing the windscreen.
X Replace the wiper blades (Y page 132). The windscreen is smeared after the vehicle has been cleaned in a
car wash.
X Clean the windscreen (Y page 346). The windscreen has been damaged by stone impact in the cam-
era's field of vision.
X Replace the windscreen. The pedestrian and ani-
mal recognition is not
available. The infrared camera in the radiator grille is dirty.
X Use a soft cloth and water to clean the infrared camera. Driving Assistance Plus package
General notes The Active Driving Assistance PLUS package
consists of DISTRONIC PLUS (Y page 191),
Active Blind Spot Assist (Y page 233) and
Active Lane Keeping Assist (Y page 236).
Active Blind Spot Assist General notes
Active Blind Spot Assist monitors the areas
on either side of the vehicle that are not visi-
ble to the driver with two lateral, rear-facing
radar sensors. A warning display in the exte-
rior mirrors draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lanes, you will also receive a visual
and audible collision warning. If a risk of side impact is detected, corrective braking may
help you avoid a collision. Active Blind Spot
Assist evaluates the free space in the direc-
tion of travel and to the side before making a
course-correcting brake application. For this, Active Blind Spot Assist uses the forward-
facing radar sensors.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
Important safety notes
Active Blind Spot Assist is only an aid and is
not a substitute for attentive driving. Driving systems
233Driving and parking Z

G
WARNING
Active Blind Spot Assist does not react to
vehicles:
R overtaking too closely on the side, placing
them in the blind spot area
R if the difference in the speed of approach
and overtaking is too great
As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and maintain a safe distance at the side of the vehicle.
Radar sensors
The Active Blind Spot Assist radar sensors are
integrated into the front and rear bumpers
and behind a cover in the radiator trim. Make sure that the bumpers and the cover in the
radiator trim 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 radar
sensors checked at a qualified specialist
workshop. Active Blind Spot Assist may oth-
erwise no longer function properly.
Monitoring range G
WARNING
Active Blind Spot Assist does not detect all
traffic situations and road users. There is a
risk of an accident.
Always make sure that there is sufficient dis-
tance to the side for other traffic or obstacles. Active Blind Spot Assist monitors the area up
to 3.0 mbehind your vehicle and directly next
to your vehicle, as shown in the diagram.
The detection of vehicles may be impaired in the case of:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to rain, snow or
spray
Vehicles in the monitoring range are then not
indicated.
Active Blind Spot Assist may not detect nar-
row vehicles, such as motorcycles or bicy-
cles, or may only detect them too late.
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 particularly long vehicles, for
example lorries, for a prolonged time 234
Driving systemsDriving and parking

G
WARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can:
R give an unnecessary warning and then
make a course-correcting brake application
to the vehicle
R neither give a warning nor intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you. Ter-
minate the intervention in a non-critical driv-
ing situation.
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
(e.g. if the road surface is wet)
R the windscreen is dirty, misted up, dam-
aged or covered, for instance by a sticker,
in the vicinity of the camera
R the radar sensors in the front or rear bump-
ers or the radiator trim are dirty, e.g.
obscured by snow
R no, or several, unclear lane markings are
present for one lane, e.g. in a construction
area
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 change quickly, e.g.
lanes branch off, cross one another or
merge
R the road is narrow and winding
R there are highly variable shade conditions
on the road If no vehicle is detected in the adjacent lane
and broken lane markings are detected, no
lane-correcting brake application is made.
Warning vibration through 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 steer-
ing wheel for up to 1.5 seconds.
Lane-correcting brake application
If you leave your lane under certain circum-
stances, the vehicle will brake briefly on one
side. This is intended to help you return the
vehicle to the original lane. G
WARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake appli-
cation. If a lane-correcting brake application occurs,
display :appears in the multifunction dis-
play. The brake application also slightly
reduces driving speed.
This function is available in the range between
60 km/h and 200 km/h.
A lane-correcting brake application can be
made after driving over a lane marking rec-
ognised as being solid or broken. Before this,
a warning must have been issued by means of
intermittent vibration through the steering Driving systems
