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

•

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 message

Time 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

374

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 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".

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.

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:

•

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
