Camera limitations (p. 338) Driver Alert Control
The Driver Alert Control (DAC) function is
designed to help capture the driver become
aware of erratic behavior, e.g. if the driver is dis-
tracted or showing signs of fatigue.
The objective of DAC is to detect slowly deterio-
rating driving behavior and is primarily intended to
be used on major roads. The function is not
intended for use in city traffic.
DAC is activated when the vehicle's speed
exceeds 65 km/h (40 mph) and remains active
as long as speeds are above 60 km/h (37 mph). DAC detects the vehicle's position in the traffic lane.
A camera monitors the traffic lane's marker lines
and compares the direction of the road with the
driver's movements of the steering wheel. The vehicle is moving erratically in the lane.
If driving behavior becomes
considerably erratic, the driver
will be alerted by this symbol in
the instrument panel, an audi-
ble signal and the messageTime for a break. If the vehicle is equipped with Sensus
Navigation* and the
Rest Stop Guidance func-
tion is activated, a suitable place to take a break
will also be suggested (see section “Selecting
guidance to a rest stop if a Driver Alert Control
warning has been given”).
The warning will be repeated after a short time if
driving behavior does not improve.

WARNING
The Driver Alert Control function is sup-
plementary driver support intended to
facilitate driving and help make it safer –
it cannot handle all situations in all traffic,
weather and road conditions.
Driver Alert Control must not be used to
extend a period of driving. The driver
should plan in breaks at regular intervals
and make sure they are well rested.
Driver Alert Control is not a substitute for
the driver's attention and judgment. The
driver is always responsible for ensuring
the vehicle is driven in a safe manner, at
the appropriate speed, with an appropri-
ate distance to other vehicles, and in
accordance with current traffic rules and
regulations.
WARNING An alarm from Driver Alert Control should be
taken very seriously since a sleepy driver is
often not aware of their own condition.
If the alarm sounds or you feel fatigued:
Stop the vehicle safely as soon as possi-
ble and rest.
Studies have shown that it is just as danger-
ous to drive while tired as it is to drive under
the influence of alcohol or other stimulants.

Driver Alert Control (p. 370) Driver Alert Control limitations
Driver Alert Control (DAC) functionality may be
reduced in certain situations.
In certain situations, the system may provide a
warning even if it has not detected a change in
driving behavior, e.g.:
in strong crosswinds
on grooved road surfaces.
WARNING In certain cases, driving behavior might not be
affected despite the driver's fatigue – when
using the Pilot Assist function – resulting in
the driver not getting a warning from DAC.
It is therefore very important to always stop
and take a break at the slightest sign of fati-
gue, regardless of whether the DAC function
has issued a warning or not.
NOTE
The function uses the vehicle's camera unit,
which has some general limitations – see the
section "Camera unit limitations".

Run-Off Mitigation with steering
assistance
This sub-function is intended to help reduce the
risk of the vehicle inadvertently running off the
road by actively steering the vehicle back onto
the road.
The function is active at speeds between
65-140 km/h (40-87 mph) on roads with clearly
visible traffic lane markings/lines.
The system uses a camera to monitor the edges
of the road and the painted side marker lines. If
the vehicle is about to cross the edge of the road,
the function will attempt to steer the vehicle back
onto the road. If this is not sufficient to keep the
vehicle on the road, the brakes will also be
applied.
However, the function will not provide either
steering assistance or braking if the turn signal is
used. The function will also not be activated if it
detects that the driver is actively operating the
vehicle.
After the system has automatically intervened,
this text message will appear in the instrument
panel: Collision avoidance assistance –

WARNING
The "Steering assistance at risk of run-
off" subfunction is supplementary driver
support intended to help improve driving
safety – it cannot handle all situations in

or similar obstacles at the side of the
road.

386 Steering assistance during collision
risks from behind*
If you become distracted and do not notice your
vehicle starting to veer out of the lane while
another vehicle is approaching from behind or is
in your vehicle's blind spot, this sub-function can
help provide assistance. The function provides assistance by steering your vehi-
cle back into your own lane.
Another vehicle in blind spot zone
Own vehicle
If your vehicle is beginning to veer out of your
lane while another vehicle is in your blind spot or
another vehicle is rapidly approaching in the next
lane, this function can help the driver steer the
vehicle back into its own lane.
Even if the driver intentionally changes lanes
using a turn signal without noticing another vehi- cle approaching, the function can provide assis-
tance.
The function is active at speeds between
60-140 km/h (37-87 mph) on roads with clearly
visible traffic lane markings/lines.
After the system has automatically intervened,
this text message will appear in the instrument
panel:

390 Park Assist*
The Park Assist function can help the driver
when maneuvering in tight spaces by indicating
distances to obstacles using audible signals and
graphics in the center display. Display view showing obstacle zones and sensor sec-
tors.
The center display shows an overview of the vehi-
cle in relation to objects that have been detected.
The marked sector indicates where the obstacle
is located. The closer the vehicle symbol is to a
marked sector forward/rearward, the closer the
detected obstacle is to your vehicle.
The side sectors change color as the distance
between the vehicle and an object decreases.
The audible signals will also speed up the closer
the obstacle is to the vehicle. The volume of the
audio system will be automatically lowered. Audible signals for obstacles in front and to the
sides of the vehicle are active when the vehicle is
moving but will cease after the vehicle has been
stationary for approx. 2 seconds. Audible signals
for obstacles behind the vehicle will remain active
even when the vehicle is stationary.
If a detected obstacle is within approx. 30 cm
(1 ft) from the front or rear of the vehicle, the
tone will become constant and the active sen-
sor's field closest to the vehicle symbol will be
filled in.
At distances within approx. 25 cm (0.8 ft) from an
obstacle to the sides of the vehicle, an rapid puls-
ing signal will be given and the active sector
fields will change color from ORANGE to RED.
The volume of the Park Assist audible signals
can be adjusted while the signal is being given
using the >II knob or in the center display's Top
view under Settings.
NOTE
Besides in the sector closest to the vehi-
cle symbol, audible warnings are only pro-
vided for objects located directly in the
vehicle's path.
WARNING
The Parking Assist function is supple-
mentary driver support intended to facili-
tate driving and help make it safer – it
cannot handle all situations in all traffic,
weather and road conditions.
The parking sensors have dead/blind
spots where objects cannot be detected.
Pay particular attention to people and
animals near the vehicle.
Parking Assist is not a substitute for the
driver's attention and judgment. The driver
is always responsible for ensuring the
vehicle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.
