DRIVER SUPPORT
Driver Alert Control
WARNING
The Driver Alert Control (DAC) function is
intended to help make the driver aware that
he or she is starting to drive less consistently,
e.g. if the driver becomes distracted or starts
to fall asleep.
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.
The objective for DAC is to detect slowly dete-
riorating driving ability and it is primarily
intended for major roads. The function is not
intended for city traffic.
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.
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).
The car is being driven erratically in the lane.
If the alarm sounds or you feel fatigued:
Stop the car safely as soon as possible
and rest.
•
If driving behaviour becomes
noticeably inconsistent, the
driver is alerted by this sym-
bol in the driver display, com-
bined with an acoustic signal
and the text message Time
to take a break.
Studies have shown that it is just as dan-
gerous to drive while tired as it is to drive
under the influence of alcohol or other
stimulants.
If the car is equipped with Sensus Navigation*
and has the function Rest Stop Guidance
activated, suggestions for an appropriate
place for a break are also displayed.
The warning is repeated after a time if driving
behaviour has not improved.
DAC reads the position of the car in the lane.
A camera detects the edge markings painted
on the carriageway and compares the align-
ment of the road with the driver’s steering
wheel movements.

Driver support functions are not a sub-
stitute for the driver's attention and
judgement. The driver is always
responsible for ensuring the car is
driven in a safe manner, at the appro-
priate speed, with an appropriate dis-
tance to other vehicles, and in accord-
ance with current traffic rules and reg-
ulations.

Limitations of Driver Alert Control
The Driver Alert Control (DAC) function may
have limitations in certain situations.

WARNING
In some cases, driving behaviour is not
affected despite driver fatigue – e.g. when
using the Pilot Assist* function – resulting
in the driver not getting a warning from
DAC.
It is therefore important to always stop and
take a break at the slightest feeling of fati-
gue, regardless of whether the function has
given a warning.
Examples of areas where CTA can assist the driver to
detect obstacles during reversing.
This function uses the car's camera and
radar units, which have certain general lim-
itations.
CTA is primarily designed to detect vehicles. In
favourable conditions it may also be able to
detect smaller objects, such as cyclists and
pedestrians.
