Driver Alert Control

Driver Alert Control

Updated 7/23/2018

The Driver Alert Control function is intended to attract the driver'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 deteriorating 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 movements.

If driving behaviour becomes seriously erratic, the driver is alerted by means of an acoustic signal combined with a symbol in the driver display and the message Time for a break soon?.

The warning is repeated after a time if driving ability does not improve.

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.

Warning

An alarm should be taken very seriously, as a sleepy driver is often not aware of his/her own condition.

In the event of an alarm or a feeling of tiredness; stop the car in a safe manner as soon as possible and rest.

Studies have shown that it is equally as dangerous to drive while tired as it is under the influence of alcohol.

Warning

Driver Alert Control does not work in all situations but is designed merely as a supplementary aid.

The driver always bears ultimate responsibility for ensuring that the vehicle is driven safely.
