Activating DAC
Press MY CAR in the center instrument panel
and go to Car settings
Driver Alert and
select On. See page 133 for more information
on the menu system.
The function is activated when the vehicle exceeds a speed of 40 mph (65 km/h). The display will show level markings of 1–5 bars, where a low number of bars indicates erratic driving. A high number of bars indicates stable driving.
If the vehicle is being driven erratically, the driver will be alerted by an audible signal and the message Driver Alert, Time for a break is displayed. The warning will be repeated after a short time if the driving pattern remains the same.
WARNING
• An alert should be taken seriously since
it is sometimes difficult for a driver to
realize that he/she is fatigued.
• In the event of a warning or if the driver
feels fatigued, stop as soon as possible
in a safe place and rest.
