Driver Alert System*
The Driver Alert System is intended to assist
drivers whose driving ability is deteriorating or
who are inadvertently leaving the lane they are
driving on.
The Driver Alert System consists of different
functions which can either be switched on at
the same time or individually:
•
Driver Alert Control - DAC (p. 233).
•
Lane Departure Warning - LDW (p. 236).
A switched-on function is set in standby
mode and is not activated automatically until
speed exceeds 65 km/h.
The function is deactivated again when speed
decreases to below 60 km/h.
Both functions use a camera which is
dependent on the lane having side markings
painted on each side.
WARNING
Driver Alert System does not work in all
situations but is designed merely as a sup-
plementary aid.
The driver always bears ultimate responsi-
bility for ensuring that the vehicle is driven
safely.

Driver Alert Control (DAC)*
The DAC function is intended to attract the
driver's attention when he/she starts to drive
less consistently, e.g. if he/she becomes dis-
tracted or starts to fall asleep.
The objective for DAC is to detect slowly
deteriorating driving ability and it is primarily
intended for major roads. The function is not
intended for city traffic.
A camera detects the side markings painted
on the carriageway and compares the section
of the road with the driver's steering wheel
movements. The driver is alerted if the vehicle
does not follow the carriageway evenly.
In some cases driving ability is not affected
despite driver fatigue. In which case there
may not be any warning issued for the driver.
For this reason it is always important to stop
and take a break in the event of any signs of
driver fatigue, irrespective of whether or not
DAC issues a warning.
NOTE
The function must not be used to extend a
period of driving. Always plan breaks at
regular intervals, and make sure you are
well rested.
Limitation
In some cases the system may issue a warn-
ing despite driving ability not deteriorating, for
example:
•
in strong side winds
•
on rutted road surfaces.
NOTE
The camera sensor has certain limitations
(p. 228).
