Driving Aids System Display 249 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. 2015 Explorer (exp) Owners Guide gf, 2nd Printing, September 2014 USA (fus)
