Traffic Sign Assist is not available in all coun-
tries. In this case, display :is shown in the
speedometer.
Important safety notes Traffic Sign Assist is only an aid and is not
always able to correctly display speed limits
and overtaking restrictions. Traffic signs
always have priority over the Traffic Sign
Assist display.
The system may be either functionally
impaired or temporarily unavailable if:
R visibility is poor, e.g. due to snow, rain, fog
or spray
R there is glare, e.g. from the sun being low in
the sky
R there is dirt, ice or misting on the wind-
screen in the vicinity of the camera
R traffic signs are hard to detect (dirt, ice,
snow)
R the traffic signs are insufficiently lit at night
R signs are ambiguous (e.g. traffic signs on
construction sites or in adjacent lanes)
R the information in the digital street map of
the navigation system is incorrect or out of
date
Activating Traffic Sign Assist X
Activate the Traffic Sign Assist display
using the on-board computer
(Y page 258).
If you have activated the display of Traffic
Sign Assist in the on-board computer, the traffic regulations (speed limits and overtak-
ing restrictions) are displayed in the instru-
ment cluster. The wrong-way warning
remains active even when the display has
been deactivated.

ter (wrong-way warning)
If no entry signs or roundabout signs are
passed, a warning message is displayed in the
instrument cluster if Traffic Sign Assist
detects that you are driving in the wrong
direction. You will then also hear a warning
tone. You should immediately check your
direction of travel in order to avoid danger to yourself and other road users. Driving systems

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

Night View Assist Plus can recognise pedes-
trians using typical characteristics, e.g. the
body contours and posture of a person stand-
ing upright.
Pedestrian recognition is then switched on
automatically if:
R Night View Assist Plus is activated.
R you are driving faster than approximately
10 km/h.
R it is dark.
If pedestrian recognition is active, readiness
symbol ;appears. Persons who are detec-
ted are highlighted by framing =. 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.
Animal recognition
Animals can be recognised in the following
situations:
R darkness
R outside built-up areas
R below an outside temperature of 32 † Night View Assist Plus can recognise larger
animals such as deer, cows or horses using
typical characteristics.
The system does not detect:
R smaller animals, e.g. dogs and cats
R animals whose silhouette is not clearly rec-
ognisable
When detected, animals are marked with
small coloured frame corners. In contrast to
pedestrian recognition, there is no separate
readiness symbol in the multifunction dis-
play.
Switching Night View Assist on/off Activation conditions
You can only activate Night View Assist if all of
the following conditions have been fulfilled:

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

Warning display
:
Warning display
Active Blind Spot Assist is not operational at
speeds below approximately 30 km/h. Vehi-
cles in the monitoring range are then not indi-
cated.
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
always lights up 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.
If you select the reverse gear, Active Blind
Spot Assist is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the
surroundings. When Active Blind Spot Assist is activated,
grey radar waves propagating backwards
appear next to the vehicle in the assistance
display in the multifunction display. Above a
speed of 30 km/h, the colour of the radar
waves in the assistance display changes to
green ;. Active Blind Spot Assist is then
ready for use. Visual and acoustic collision warning
If you switch on the turn signals to change
lanes and a vehicle is detected in the side
monitoring range, you receive a visual and
acoustic collision warning. You will then hear
a double warning tone and red warning
lamp :flashes. If the turn signal remains on,
detected vehicles are indicated by the flash-
ing of red warning lamp :. There are no fur-
ther warning tones.
Course-correcting brake application
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. G
WARNING
A course-correcting brake application cannot always prevent a collision. There is a risk of an
accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake appli-
cation. Always maintain a safe distance at the sides. If a course-correcting brake application
occurs, red warning lamp
:flashes in the
exterior mirror and a dual warning tone
sounds. In addition, display ;underlining
the danger of a side collision appears in the
multifunction display.
In very rare cases, the system may make an
inappropriate brake application. A course-
correcting brake application may be interrup- Driving systems

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
ESP ®
or PRE-SAFE ®
Brake
R ESP ®
is deactivated
R a loss of tyre pressure or a defective tyre is
detected

Active Lane Keeping Assist monitors the area
in front of your vehicle by means of camera
system :at the top of the windscreen. Var-
ious different areas to the front, rear and side
of your vehicle are also monitored with the aid
of the radar sensor system. Active Lane Keep-
ing Assist detects lane markings on the road
and can warn you before you leave your lane
unintentionally. If you do not react to the
warning, a lane-correcting application of the
brakes can bring the vehicle back into the
original lane.
If you select km kmin the Display unit

the assistance range begins at 40 mph.
Important safety notes
If you fail to adapt your driving style, Active
Lane Keeping Assist can neither reduce the
risk of an accident nor override the laws of
physics. Active Lane Keeping Assist cannot
take account of road and weather conditions. It may not recognise traffic situations. Active Lane Keeping Assist is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time, and for staying in lane.
Active Lane Keeping Assist cannot continu-
ously keep your vehicle in its lane. 236

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
