When active, the system monitors your
alertness level based upon your driving
behavior in relation to the lane markings and
other factors.
System Warnings
Note: The system does not issue warnings
below approximately 40 mph (64 km/h).
The warning system has two stages. First,
the system issues a temporary warning that
you need to take a rest. This message only
appears for a short time. If the system
detects further reduction in driving alertness,
it may issue another warning that remains in
the information display for a longer time. You
can press OK on the steering wheel control
to clear the warning.
System Display
When active, the system runs automatically
in the background and only issues a warning
if required. You can view the status at any
time using the information display. See
General Information (page 109).
The alertness level is shown by six steps in
a colored bar.
E131358
The current assessment of your alertness is
within a typical range.
E131359
The current assessment of your alertness
indicates that you should rest as soon as
safely possible.
The status bar travels from left to right as the
calculated alertness level decreases. As the
meter approaches the rest icon, the color
turns from green to yellow to red.
The yellow position indicates the first
warning is active and the red position
indicates the second warning is active.
Note: If you have recently received a
warning, you should consider resting, even
if the current assessment is within 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 changes to
grey for a short time and the information
display informs 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.
