Limitations of Driver Alert Control
The Driver Alert Control (DAC) function may
have limitations in certain situations.
In some cases, driving behaviour may not be
affected, despite the driver being tired - e.g. when
using the Pilot Assist function - with the result
that the driver is then not given a warning from
DAC. For this reason, it is always very important
to stop and take a break in the event of the
slightest sign of driver fatigue, regardless of
whether DAC has given a warning.
In some cases the system may issue a warning
despite driving ability not deteriorating, for exam-
ple:
•
in strong side winds
•
on rutted road surfaces.
NOTE
The function uses the car's camera unit,
which has some general limitations, see the
"Limitations for camera unit" section.

Lane Keeping Aid
The function of lane assistance is to help the
driver to reduce the risk of the car accidentally
leaving its own lane on motorways and similar
major routes.
Lane assistance steers the car back into its lane
and/or warns the driver with an acoustic signal or
steering wheel vibration.
Lane Keeping Aid is active within the speed
range 65-200 km/h (40-125 mph) on roads with
clearly visible side lines.
On narrow roads the function may be unavailable,
in which case it goes into standby mode. The
function becomes available again when the road
is wide enough.
A camera reads the side lines of the road/lane.
