2014 MERCEDES-BENZ M-Class low beam

The hazard warning lamps automatically
switch on if:
R
an air bag is deployed.
R the vehicle decelerates rapidly from a
speed of more than 45mph (70 km/h) and
comes to a standstill.
The hazard warning lamps switch off
automatically if the vehicle reaches a speed
of over 6mph (10km/h) again after a full
brake application.
i The hazard warning lamps still operate if
the ignition is switched off. Headlamp cleaning system
The headlamps are cleaned automatically if
the "Wipe with washer fluid" function is
operated five times (Y page 132) while the
lights are on and the engine is running. When
you switch off the ignition, the automatic
headlamp cleaning system is reset and
counting is resumed from 0. Active light function
The active light function is a system that
moves the headlamps according to the
steering movements of the front wheels. In
this way, relevant areas remain illuminated
while driving. This allows you to recognize
pedestrians, cyclists and animals.
Active: whenthe lights are switched on. Cornering light function
The cornering light function improves the
illumination of the road over a wide angle in
the direction you are turning, enabling better
visibility in tight bends, for example. It can
only be activated when the low-beam
headlamps are switched on.
Active:
R
if you are driving at speeds below
25mph (40 km/h) and switch on the turn
signal or turn the steering wheel
R if you are driving at speeds between
25mph (40 km/h) and45mph (70 km/h)
and turn the steering wheel
Not active: if your speed exceeds
25mph (40 km/h) or if you switch off the turn
signal or turn the steering wheel to the
straight-ahead position.
The cornering light function may remain lit for
a short time, but is automatically switched off
after no more than three minutes. Adaptive Highbeam Assist
Important safety notes G
WARNING
Adaptive Highbeam Assist does not recognize
road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier Exterior lighting
125Lights and windshield wipers
Z

In very rare cases, Adaptive Highbea
mAssist
may fail to recognize other road users that
have lights, or may recognize them too late.
In this or similar situations, the automatic
high-beam headlamps will not be deactivated
or activated regardless. There is a risk of an
accident.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. You
are responsible for adjusting the vehicle's
lighting to the prevailing light, visibility and
traffic conditions.
In particular, the detection of obstacles can
be restricted if there is:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or the sensors are
obscured
General notes You can use this function to set the
headlamps to change between low beam and
high beam automatically. The system
recognizes vehicles with their lights on, either
approaching from the opposite direction or traveling in front of your vehicle, and
consequently switches the headlamps from
high beam to low beam.
The system automatically adapts the low-
beam headlamp range depending on the
distance to the other vehicle. Once the
system no longer detects any other vehicles,
it reactivates the high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control
panel.

If you are driving at speeds above
approximately 35 mph (55 km/h) and no
other road users have been detected:
The high-beam headlamps are switched on
automatically. The 000Cindicator lamp in
the instrument cluster also lights up.
If you are driving at speeds below
approximately 30 mph (45 km/h) or other
road users have been detected or the roads
are adequately lit:
The high-beam headlamps are switched off
automatically. The 000Cindicator lamp in
the instrument cluster goes out. The 0005
indicator lamp in the multifunction display
remains lit.
X To deactivate: move the combination
switch back to its normal position.
The 0005 indicator lamp in the instrument
cluster goes out. Headlamps fogged up on the inside
The headlamps may fog up on the inside if
there is high atmospheric humidity.
X Switch on the lights and drive off.
The level of moisture diminishes,
depending on the length of the journey and
the weather conditions (humidity and
temperature).
If the level of moisture does not diminish:

Warning and display messages in the
multifunction display
X
Activate ATTENTION ASSIST using the on-
board computer (Y page 273).
X If ATTENTION ASSIST is active, it will not
warn you until at least 20 minutes after
you rjourney has begun. You then hear an
intermittent warning tonet wice and the
Attention Assist: Take a Break! message appears in the multifunction
display.
If necessary, take a break.
X Press the 000Bor0007 button to confirm
the message.
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
still detects increasing lapses in
concentration, you will be warned again after
15 minutes at the earliest.
ATTENTION ASSIST is reset when you
continue 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. 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
0002picks 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,
pedestrians recognized by the system are
highlighted in the Night View Assist Plus
display.
Light from the headlamps of oncoming
vehicles 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
traffic.
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
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 a sticker, in the
vicinity of the camera
R on bends, on uphill gradients or downhill
gradients 230
