Road Sign Information* (p. 357) 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). 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. If the driving behavior becomes
noticeably erratic, the driver will
be alerted by this symbol in the
instrument panel and the mes-
sage
Time for a break
soon?.
If driving behavior does not improve but instead
becomes even more erratic, the driver will be
alerted by the same symbol in the instrument
panel, an audible signal and the message Time
for a break. If the Rest Stop Guidance function is activated
in Sensus Navigation* when the Time for a
break warning is given, suggestions will also be provided for suitable places to take a break. 105

The warnings 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.

Related information
• 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

. 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".
