ted, the function switches off. The COMAND
display switches back to the previously selec-
ted view. You can also switch the display by
selecting the 0039symbol in the display and
pressing 0098the COMAND controller to con-
firm. ATTENTION ASSIST
General notes ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways.
It is active in the range between 50 mph
(80 km/h) and 112 mph (180 km/h). If
ATTENTION ASSIST detects typical indicators
of fatigue or increasing lapses in concentra-
tion on the part of the driver, it suggests you
take a break.
Important safety notes ATTENTION ASSIST is only an aid to the
driver. It might not always recognize fatigue
or increasing inattentiveness in time or fail to
recognize them at all. The system is not a
substitute for a well-rested and attentive
driver.
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 50 mph (80 km/h) or faster than
112 mph (180 km/h)
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed
ATTENTION ASSIST is reset when you con-
tinue your journey and starts assessing your
tiredness again if:
R you switch off the engine.
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break. Driving systems

Activating ATTENTION ASSIST
X
Activate ATTENTION ASSIST using the on-
board computer (Y page 284).
When ATTENTION ASSIST is deactivated, the 00D7 symbol appears in the multifunction
display in the assistance graphic display.
ATTENTION ASSIST is activated automatically
after the engine is started up.
Warning and display messages in the
multifunction display If fatigue or increasing lapses in concentra-
tion are detected, a warning appears in the
multifunction display: Attention Assist: Attention Assist:
Take a Break!
Take a Break!
In addition to the message shown in the mul-
tifunction display, you will then hear a warn-
ing tone.
X If necessary, take a break.
X Confirm the message by pressing the 0076
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, you will be warned again
after 15 minutes at the earliest. The precon-
dition for this is that ATTENTION ASSIST still
detects typical indicators of fatigue or
increasing lapses in concentration. 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 0043picks up the
infrared light and displays a monochrome
image in COMAND. The image displayed in
COMAND 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. If pedestrian recognition is activated, pedes-
trians recognized by the system are highligh-
ted 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 high-
beam headlamps due to oncoming traffic.
i Infrared 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:
R there is poor visibility, e.g. due to snow,
rain, fog or spray
R the windshield is dirty, fogged up or cov-
ered, for instance by a sticker, in the vicinity
of the camera
R on bends, on uphill gradients or downhill
gradients 242

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
R pedestrians do not contrast adequately
from the background
R pedestrians are not in an upright position,
e.g. sitting, squatting or lying
Activating Night View Assist Plus Activation conditions
You can only activate Night View Assist Plus
if:
R the SmartKey is in position 2in the ignition
lock.
R it is dark.
R the light switch is in the 0058or0058 posi-
tion.
R reverse gear has not been engaged.
Activating Night View Assist Plus X
Make sure that COMAND is switched on.

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
operating instructions. i
The infrared headlamps only switch on
when the vehicle is being driven at speeds
of approximately 6 mph (10 km/h). This
means that you do not have the full visual
range while the vehicle is stationary and
cannot check whether Night View Assist
Plus is working.

Night View Assist Plus is able to recognize
pedestrians by typical characteristics, e.g. a
silhouette in the shape of a person.
Pedestrian recognition is then switched on
automatically if:
R Night View Assist Plus is activated.
R you are driving faster than approximately
6 mph (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 0085
appears. If pedestrians are detected, they are
highlighted with framing 0087. 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. Driving systems

It may be the case that objects are highlighted
as well as pedestrians.
Fogged up or dirty windshield If the windshield in front of the camera is fog-
ged up or dirty on the inside or outside, the
Night View Assist Plus display is affected.

General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 245) and Lane Keeping
Assist (Y page 247).
Blind Spot Assist General notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from a speed of
approximately 20 mph (30 km/h) . A warning
display in the exterior mirrors draws your
attention to vehicles detected in the moni-
tored area. If you then switch on the corre-
sponding turn signal to change lanes, you will
also receive an optical and audible collision
warning. Blind Spot Assist uses sensors in the rear bumper for monitoring purposes. Important safety notes G
WARNING
Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving.

warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
Monitoring range of the sensors
In particular, the detection of obstacles can
be impaired if:
R there is dirt on the sensors or anything else
covering the sensors
R there is poor visibility, e.g. due to fog, heavy
rain, snow or spray
R there are narrow vehicles, e.g. motorcycles
or bicycles
R the road has very wide lanes
R the road has narrow lanes
R you are not driving in the middle of the lane
R there are barriers or similar lane borders
Vehicles in the monitoring range are then not indicated. Blind Spot Assist monitors the area up to 10 ft
(3 m) behind 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 driving at the
inner edge of their lanes.
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 the warning is canceled when driving for an
extended period next to long vehicles, such
as trucks.
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 condition of theradar sensors checked at a qualified special-
ist workshop. Blind Spot Assist may other-
wise not work properly.
Indicator and warning display
Blind Spot Assist is not active at speeds below approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated. 0043
Yellow indicator lamp/red warning lamp
When Blind Spot Assist is activated, indicator
lamp 0043in the exterior mirrors lights up yel-
low at speeds of up to 20 mph (30 km/h). At
speeds above 20 mph (30 km/h), the indica-
tor lamp goes out and Blind Spot Assist is
operational.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp 0043on the corre- 246
