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 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, a service station search is performed in
COMAND. You can select a service station
and navigation to this service station will then
begin. This function can be activated and
deactivated in COMAND. 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 0044picks 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 0043. The camera helps
detect pedestrians and animals. Observe the notes on cleaning the infrared camera
(Y page 331).
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 if there is poor visibility, e.g. due to snow,
rain, fog or spray
R if the windshield is dirty, fogged 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 grill is dirty, fogged 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. Driving systems
