Driver Alert Control (DAC)
DAC is intended to alert the driver if his/her driv-
ing becomes erratic due to e.g., distraction or
fatigue.
DAC is designed to help detect a slowly chang-
ing driving pattern. It is primarily intended to be
used on main roads and is not meant for use in
city traffic.
The function activates initially when the vehicle's
speed first exceeds 40 mph (65 km/h) and
remains active as long the speed remains above
approx. 37 mph (60 km/h)
A camera monitors the traffic lane's side marker
lines and compares the direction of the road with
the driver’s movements of the steering wheel.
If the driving pattern starts to
become noticeably erratic, the
driver will be alerted by this
symbol in the instrument panel
along with the text
Driver Alert
Time for a break.
If the driving pattern does not change, the driver
will be warned by the same symbol in the instru-
ment panel combined with an audible signal and
the text
Time for a break.
If the
Rest Stop Guidance function is activated
in the navigation system when Time for a break
is displayed, suggested rest areas will also be
displayed.
The warning will be repeated if the driving pattern
does not change.
WARNING
•
DAC is not intended to extend the dura-
tion of driving. Always plan breaks at reg-
ular intervals to help remain alert.
•
A warning from DAC should not be
ignored. A driver may not be aware of
how fatigued he/she has become.
•
In certain cases, fatigue may not affect
the driver’s behavior. In situations of this
type, no warning will be provided. There-
fore, it is important to take breaks at reg-
ular intervals, regardless of whether or
not DAC has given a warning.
