.
If the vehicle exceeds a
detected speed limit with the
Speed Warning function acti-
vated, the driver is given a
speed warning when the vehi-
cle is approaching a speed
camera if the navigation map
for the vehicle's current location contains infor-
mation on speed cameras. For more information on Speed Warnings in con-
junction with speed cameras, see "Road Sign
Information with Speed Warning and settings"
and "Road Sign Information limitations".
NOTE
•
For an audible alert to be provided if the
speed is exceeded, the
Speed Limit
Warning function must be activated and
the Road Sign Audio Warning sub- function must be On. Audible alerts are
provided if the vehicle's speed exceeds
the speed displayed by RSI in the instru-
ment panel.
• Information about speed cameras on the
navigation map is not available for all
markets/areas.

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.

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

The steering wheel vibrations vary. The more time the vehicle is over th\
e lane marker line, the longer the vibrations.

In certain demanding driving conditions, Lane
Keeping Aid may not be able to properly assist
the driver. In these situations, it is recommended
that the function be deactivated. Examples of such situations include:
• road work
• winter driving conditions
• poor road surfaces
• a very sporty driving style
• bad weather with reduced visibility
• roads with indistinct or no lane markings
• sharp edges or lines other than the lane's
side markings
• when the power steering works at reduced
power - e.g. during cooling due to overheat-
ing (see section "Speed-dependent steering
force").

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.

site direction, this function can help the driver
steer the vehicle back into its own lane. However, the function will not provide steering
assistance if the turn signal is used. The function
will also not be activated if it detects that the
driver is actively operating the vehicle.
