Driver Alert Control
The Driver Alert Control (DAC) function is
intended to attract the driver's attention when he
or she starts to drive less consistently, e.g. if the
driver 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.
The function is activated when speed exceeds
65 km/h (40 mph) and remains active as long as
the speed is over 60 km/h (37 mph).
A camera detects the edge markings painted on
the carriageway and compares the alignment of
the road with the driver’s steering wheel move-
ments.
When driving behaviour starts
to become inconsistent, the
driver is alerted by this symbol
in the driver display, together
with the text message
Time
for a break soon?
.
If driving behaviour does not improve but
becomes noticeably inconsistent, the driver is
alerted by the same symbol in the driver display,
combined with an acoustic signal and the text
message
Time to take a break .
If the Rest Stop Guidance function is activated
in Sensus Navigation * , suggestions for a suitable
location for a break are also shown with the
Time to take a break warning.
The warnings are repeated after a time if driving
behaviour has not improved.
WARNING
•
The Driver Alert Control function is sup-
plementary driver support intended to
facilitate driving and make it safer – it
cannot handle all situations in all traffic,
weather and road conditions.
•
Driver Alert Control should not be used to
extend a period of driving. The driver
should instead plan for breaks at regular
intervals and make sure they are well
rested.
•
Driver Alert Control is not a substitute for
the driver's attention and judgement. The
driver is always responsible for ensuring
the car 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.
WARNING
An alarm from Driver Alert Control should be
taken very seriously, as a sleepy driver is often
not aware of his/her own condition.
If the alarm sounds or you feel fatigued:
•
Stop the car safely as soon as possible
and rest.
Studies have shown that it is just as danger-
ous to drive while tired as it is to drive under
the influence of alcohol or other stimulants.
