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.
