Active Parking Assist is switched on
automatically when driving forwards. The
system is operational at speeds of up to
approximately 22 mph (35 km/h). While in
operation, the system independently locates
and measures parking spaces on both sides
of the vehicle.
Active Parking Assist will only detect parking
spaces:
R that are parallel or at right-angles to the
direction of travel
R that are parallel to the direction of travel
and at least 59 in (1.5 m) wide
R that are parallel to the direction of travel
and at least 39.5 in (1.0 m) longer than your
vehicle
R that are at right-angles to the direction of
travel and at least 39.5 in (1.0 m) wider
than your vehicle
i Note that Active Parking Assist cannot
measure the length of a parking space if it
is at right angles to the direction of travel.
You will need to judge whether your vehicle
will fit in the parking space.
When driving at speeds below 19 mph
(30 km/h), you will see parking symbol as a
status indicator in the instrument cluster.
When a parking space has been detected, an
arrow towards the right or the left also
appears. By default, Active Parking Assist
only displays parking spaces on the front- passenger side. Parking spaces on the
driver's side are displayed as soon as the turn
signal on the driver's side is activated. When
parking on the driver's side, this must remain
switched on until you acknowledge the use of
Active Parking Assist by pressing the
0076
button on the multifunction steering wheel.

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 length of the journey is less than
approximately 30 minutes
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 37 mph (60 km/h) or faster than
125 mph (200 km/h)
R if you are driving with the active Steer
Assist of DISTRONIC PLUS
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
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. Displaying the attention level You can have current status information
displayed in the assistance menu
(Y
page 259) of the on-board computer.
X Select the Assistance display for Attention
Assist using the on-board computer
(Y page 258).
The following information is displayed:
R length of the journey since the last break.
R the attention level determined by
ATTENTION ASSIST, displayed in a bar
display in five levels from high to low.
R if ATTENTION ASSIST is unable to calculate
the attention level and cannot output a
warning, the System Passive System Passive message
appears. The bar display then changes the
display, e.g. if you are driving at a speed
below 37 mph (60 km/h) or above
124 mph (200 km/h).
Activating ATTENTION ASSIST X
Activate ATTENTION ASSIST using the on-
board computer (Y page 261).
The system determines the attention level
of the driver depending on the setting
selected:
Standard selected: the sensitivity with
which the system determines the attention
level is set to normal.
Sensitive selected: the sensitivity is set
higher. The attention level detected by
Attention Assist is adapted accordingly and
the driver is warned earlier. Driving systems
235Driving and parking Z
When ATTENTION ASSIST is deactivated, the
00AD symbol and OFF appear in the
multifunction display in the assistance
display when the engine is running.
When ATTENTION ASSIST has been
deactivated, it is automatically reactivated
after the engine has been stopped. The
sensitivity selected corresponds to the last
selection activated (standard/sensitive).
Warning in the multifunction display If fatigue or increasing lapses in
concentration are detected, a warning
appears in the multifunction display:
Attention Assist: Take a Break! Attention Assist: Take a Break!
In addition to the message shown in the
multifunction display, you will then hear a
warning 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
concentration, you will be warned again after
15 minutes at the earliest. This will only
happen if ATTENTION ASSIST still detects
typical indicators of fatigue or increasing
lapses in concentration.
If a warning is output in the multifunction
display, 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
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.
In addition, thermal imaging camera 0043is
integrated in the radiator grill. The camera
helps detect pedestrians and animals.
Observe the notes on cleaning the thermal
imaging camera (Y page 359).
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 adapt236
