For more information on Speed Warnings in con-
junction with speed cameras, also see “Road
Sign Information with Speed Warning and Set-
tings” 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.
It is possible to receive an audible alert
for speed cameras regardless of the vehi-
cle's speed, whether or not the speed
limit is exceeded, and even if the
Road
Sign Audio Warning function is deacti- vated: See heading "Speed camerawarning On/Off" in section "Road Sign
Information with Speed Warning and set-
tings" and select Speed Camera Audio
Warning there.
Information about speed cameras on the
navigation map is not available for all
markets/areas.

Road Sign Information (RSI 101
) functionality may
be reduced in certain situations.
RSI could have reduced functionality due to e.g.:
faded road signs
signs located in a curve in the road
twisted or damaged signs
signs positioned high above the road
fully/partially obstructed or poorly positioned
signs
signs partially or fully covered by frost, snow
and/or dirt
digital road maps 102
that are outdated, incor-
rect or do not contain speed information 103
.
NOTE Certain types of bike carriers that are con-
nected to the trailer socket may be interpre-
ted as a connected trailer by the RSI function.
In such cases, the instrument panel may indi-
cate incorrect speed information.

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.

DRIVER SUPPORT
371
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".

Camera limitations (p. 338) Lane Keeping Aid
Lane Keeping Aid (LKA 104
) 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 106
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 106
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. 105
The steering wheel vibrations vary. The more time the vehicle is over th\
e lane marker line, the longer the vibrations.

Aid".
