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".

Driver Alert Control (p. 370)
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.

373 Lane Keeping Aid steers the vehicle back into its lane.
Lane Keeping Aid alerts the driver using vibrations in the
steering wheel
105
. 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.
106 See "LKA assistance options" under "Activating/deactivating Lane Keeping\
Aid".

Lane Keeping Aid does not intervene in sharp inside
curves.
In certain cases, such as when a turn signal is
used or when "straightening out" an inside curve,
Lane Keeping Aid will not provide steering assis-
tance or alerts.
