Driver Alert Control (DAC)
*
The DAC function is intended to attract the driv-
er's attention when he/she starts to drive less
consistently, e.g. if he/she becomes distracted
or starts to fall asleep.
The objective for DAC is to detect slowly deterio-
rating 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 regu-
lar intervals, and make sure you are well
rested.
Limitation
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 camera sensor has certain limitations
(p. 230).
