• Driver Alert Control (p. 362) 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".

Driver Alert Control (p. 362) Lane Keeping Aid
Lane Keeping Aid (LKA 107
) is designed to
actively steer the vehicle on freeways, highways
and other major roads to help the driver reduce
the risk of the vehicle unintentionally veering out
of the lane.
Lake Keeping Assistance steers the vehicle back
into the lane and/or alerts the driver using vibra-
tions in the steering wheel.
Lane Keeping Aid is active at speeds between
65-200 km/h (40-125 mph) on roads with
clearly visible traffic lane marker lines.
On narrow roads, the function may be unavailable
and go into standby mode. The function will
become available again when the road becomes
sufficiently wide. A camera monitors the road/traffic lane's marker lines.

Lane Keeping Aid alerts the driver using vibrations in the
steering wheel
108
. Depending on the settings used, Lane Keeping
Aid functions in different ways:
• With
Assist 109
activated: When the vehicle
approaches a lane marker line, LKA will
actively steer the vehicle back into the lane
using light pressure on the steering wheel.
• With
Warning 109
activated: If the vehicle is
about to move over a lane marker line, the
driver will be alerted by vibrations in the
steering wheel.
NOTE When the direction indicator is activated, the
Lane Keeping Aid does not provide any warn-
ing or intervene with steering.
WARNING •
The Lane Keeping Aid function is supple-
mentary driver support intended to help
improve driving safety – it cannot handle
all situations in all traffic, weather and
road conditions.
• The function 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. 108
The steering wheel vibrations vary. The more time the vehicle is over th\
e lane marker line, the longer the vibrations.

Aid".

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 –
Automatic intervention
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
all traffic, weather and road conditions.
• The function cannot detect barriers, rails
or similar obstacles at the side of the
road.
• "Steering assistance at risk of run-off" 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 appropri-
ate speed, with an appropriate distance to
other vehicles, and in accordance with
current traffic rules and regulations.

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, the closer the detected obstacle
is to your vehicle.
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 30 cm (1 ft) from
the front or rear of the vehicle, the tone will
become constant and the active sensor's field
closest to the vehicle symbol will be filled in.
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 •
Acoustic warnings are only given for
objects directly in front of the vehicle's
path.

mentary driver support intended to facili-
tate driving and help make it safer – it
