ATTENTION ASSIST
General notes
ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways.
It is active in the 37 mph (60 km/h) to
125 mph (200 km/h) range. If ATTEN-
TION ASSIST detects typical indicators of fati-
gue or increasing lapses in concentration on
the part of the driver, it suggests taking a
break.

Important safety notes
ATTENTION ASSIST isonlyan aid to the
driv er.Itmight not always recogniz e fatigue
or increasing inattentiveness in time or fail to
recogniz e them at all. The system is not a
substitute for a well-rested and attentive
driv er.
The functionalit y of ATTENTION AS SIST is
restricted and warnings may bedelayed or
not occur at all:
Rifthe length of the journey isless than
appr oximately 30 minutes
Rifthe road cond ition ispoor, e.g. ifthe sur-
face isuneven or if there are potholes
Rifthere isa strong side wind
Rifyou have adopted a sporty driving style
wit h high cornering speeds or high rates of
acceleration

tifunction display, you will then hear a warn-
ing tone.
XIf necessary, take a break.
XConfirm the message by pressing the a
button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break and ATTENTION ASSIST
continues to detect increasing lapses in con-
centration, you will be warned again after
15 minutes at the earliest. This will only hap-
pen if ATTENTION ASSIST still detects typical
indicators of fatigue or increasing lapses in
concentration.
If a warning is output in the multifunction dis-
play, COMAND performs a service station
search. You can select a service station and
navigation to this service station will then
begin. This function can be activated and
deactivated in COMAND.
Traffic Sign Assist
General notes
Traffic Sign Assist displays the maximum
speed permitted to the driver in the instru-
ment cluster. The data and general traffic reg-
ulations stored in the navigation system are
used to determine the current speed limit. As Traffic Sign Assist is a map-based system,
traffic signs put up temporarily (e.g. near
roadworks) are not detected.
If a traffic sign that is relevant to your vehicle
is passed, the display of the speed limits is
updated.
Traffic signs with a restriction indicated by an
additional sign (e.g. in wet conditions) are
also shown.
The traffic signs are only displayed with the
restrictions if:
Rthe regulation must be observed with the
restriction, or
RTraffic Sign Assist is unable to determine
whether the restriction applies
If Traffic Sign Assist is unable to determine a maximum permitted speed from any of the
available sources, no speed limit is displayed
in the instrument cluster either.
Traffic Sign Assist is not available in all coun-
tries. In this case, symbol :is shown in the
assistance graphic display (
Ypage 243).
Important safety notes
Traffic Sign Assist is only an aid and is not
always able to correctly display speed limits.
Traffic signs always have priority over the
Traffic Sign Assist display.
The system may be either functionally
impaired or temporarily unavailable if the
information in the digital street map of the
navigation system is incorrect or out of date.

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 high-beam headlamps. This enables you to see the road's course and any obstacles in
good time. When pedestrian recognition is
active, pedestrians recognized by the system are visually highlighted in color in the Night
View Assist Plus display with small frame cor-
ners.
In addition, an infrared camera is integrated
into the radiator trim :. The camera helps
detect pedestrians and animals. Observe the
notes on cleaning the infrared camera
(
Ypage 337).
iInfrared light is not visible to the human
eye and therefore does not glare. Night
View Assist Plus can therefore remain
switched on even if there is oncoming traf-
fic.
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 if:
Rif there is poor visibility, e.g. due to snow,
rain, fog or spray
Rif the windshield is dirty, fogged up or cov-
ered, for instance by a sticker, in the vicinity
of the camera
Rif the thermal imaging camera in the radia-
tor grill is dirty, fogged up or covered
Ron bends, hilltops or downhill gradients
Rat 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:
Rpedestrians or animals are partially or
entirely obscured by other objects, e.g.
parked vehicles
Rthe 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
Rpedestrians or animals do not contrast with
the surroundings
Rthe camera system no longer recognizes
pedestrians as persons due to special
clothing or other objects
Rpedestrians are not in an upright position,
e.g. sitting, squatting or lying
Ranimals are not recognized by the system,
e.g. because of their size or shape
Pedestrian and animal recognition is deacti-
vated at temperatures above 90 ‡ (32 †).
The spotlight function and automatic delayed
switch-off are then no longer active.

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
windshield to evaluate the situation. The
actual distance to objects and pedestrians
cannot be gaged accurately by looking at a
screen.
Animal recognition
Animals can be recognized in the following
situations:
Rdarkness
Routside built-up areas
Rbelow an outside temperature of 90 ‡
(32 †) Night View Assist Plus can recognize larger
animals such as deer, cows or horses using
typical characteristics.
The system does not detect:
Rsmaller animals, e.g. dogs and cats
Ranimals whose silhouette is not clearly rec-
ognizable
When detected, animals are marked with
small color frame corners. In contrast to
pedestrian recognition, there is no separate
readiness symbol in the multifunction dis-
play.

Driving Assistance PLUS package
General notes
The Driving Assistance PLUS package con-
sists of DISTRONIC PLUS (
Ypage 182), Active
Blind Spot Assist (
Ypage 222) and Active
Lane Keeping Assist (
Ypage 225).
Active Blind Spot Assist
General notes
Active Blind Spot Assist uses a radar sensor
system, pointed toward the rear of the vehi-
cle, to monitor the area to the sides of the
vehicle which the driver is unable to see. A
warning display in the exterior mirrors draws
your attention to vehicles detected in the
monitored area. If you then switch on the cor-
responding turn signal to change lanes, you
will also receive a visual and audible collision
warning. If a risk of lateral collision is detec- ted, corrective braking may help you avoid a
collision. Before a course-correcting brake
application, Active Blind Spot Assist evalu-
ates the space in the direction of travel and at
the sides of the vehicle. For this, Active Blind
Spot Assist uses radar sensors which are
pointed in the direction of travel.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h)
.
Important safety notes
Active Blind Spot Assist is only an aid and is
not a substitute for attentive driving.
GWARNING
Active Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
