System Display
When active the system will run automatically in the background and
only issue a warning if required. You can view the status at any time
using the information display. Refer to the
Information Displays
chapter.
The alertness level is shown by six steps in a colored bar.
The current assessment of your
alertness is within a typical range.
The current assessment of your
alertness indicates that you should
rest as soon as safely possible.
The status bar will travel from left to right as the calculated alertness
level decreases. As the rest icon is approached the color turns from
green to yellow to red. The yellow position represents the first warning
is active and the red position represents the second warning is active.
Note:
If you have recently received a warning; you should consider
resting, even if the current assessment is with the typical range.
Note:
If the camera sensor cannot track the road lane markings or if
your vehicle speed drops below approximately 40 mph (64 km/h), the
alertness level will change to grey for a short time and the information
display will inform you that the system is unavailable.
Resetting the System
You can reset the system by either:
•
Switching the ignition off and on.
•
Stopping the vehicle and then opening and closing the driver’s door.
