Mercedes-Benz SL-Class 2014 Owners Manual - Manual (Page 216)

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
surface 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 you are currently using COMAND or
making a telephone call with it
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 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.
Warning and display messages in the
multifunction display

board computer (

page 235).
If ATTENTION ASSIST is active, you will be
warned no sooner than 20 minutes after
your journey has begun. You then hear an
intermittent warning tone twice and the
Attention Assist: Take a Break! Attention Assist: Take a Break!
message appears in the multifunction
display.
X
If necessary, take a break.
X Press the a or % button to confirm

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.
When ATTENTION ASSIST is deactivated, the
é symbol appears in the multifunction
display in the assistance graphics display.
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.
Camera ; of Night View Assist Plus picks up
the infrared light and displays a black and
white image in COMAND. The image shown
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. 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
corners.
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.
