Important safety notes Night View Assist Plus is only an aid and is not
as ubstitute for attentive driving. Do not rely
on the Night View Assist Plus display .You are
responsible for the distance to the vehicle in
front,f or 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
function if:
R
there is poor visibility, e.g. due to snow,
rain, fog or spray
R the windshield is dirty, fogged up or
covered, for instance by asticker, in the
vicinit yofthe 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 incomplet eor
interrupted, e.g. by powerful light
reflections
R pedestrians do not contrast adequately
from the background
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
001Apicks up
the infrared light and display samonochrome
image in COMAND. The image displayed in
COMAND corresponds to aroad 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,
pedestrians recognized by the system are 204

highlighted in the Night View Assist Plus
display.
Light from the headlamps of oncoming
vehicles does not affect the Night View Assist
Plus displayint
he 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
traffic.
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 000Dor001D
position.
R reverse gear has not been engaged.

The infrared headlamps only switch on
when the vehicle is being driven at speeds
of approximately 6mph (10 km/h). This
means that you do not have the full visual

WARNING
Always remembe rthat you must concentrate
primarily on driving the vehicle. Adriver's
attention to the road must always be his/her
primary focus when driving. For your safety
and the safety of others: stop the vehicle
before attempting to clean fogged up
windows or the windshield area in front of the
Night View Assist Plus camera.
Please remember that when your vehicle is
traveling at aspeed of only 30 mph
(approximately 50 km/h )itcovers adistance
of 44 ft (approximately 14 m) per second.
If the windshield in front of the camera is
fogged up or dirty on the inside or outside, the
Night View Assist Plus displayisa ffected.

Active Blind Spot Assist Genera
lnotes
Active Blind Spot Assis tuses aradar sensor
system, pointed toward the rear of the
vehicle, to monitor the area to the sides of the
vehicle which the driver is unable to see. A
warning displayint he exterior mirrors draws
your attention to vehicles detected in the
monitored area. If you then switch on the
corresponding turn signal to change lane, you
will also receive an optical and audible
warning. If arisk of lateral collision is
detected, corrective braking may help you
avoid acollision. Before acourse-correcting
brake application, Active Blind Spot Assist
evaluates 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).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be:

Important safety notes
Active Blind Spot Assist is only an aid and is
not asubstitute for attentive driving. G
WARNING
Active 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 alarge speed
