238 Parking Aids A. Coverage area of up to 27 inches (70 centimeters) from the front of the vehicle and about 6-9 inches (15-23 centimeters) to the side of the front end of the vehicle. Refer to the reverse sensing section for details on coverage area. A The system sounds an audible warning when obstacles are near either bumper in the following manner: • Objects detected by the front sensors are indicated by a high-pitched tone from the front of the vehicle. • Objects detected by the rear sensors are indicated by a lower pitched tone from the rear of the vehicle. • The sensing system reports the obstacle which is closest to the front or rear of the vehicle. For example, if an obstacle is 12 inches (30 centimeters) from the front of the vehicle and, at the same time, an obstacle is only 6 inches (15 centimeters) from the rear of the vehicle, the lower pitched tone sounds. • An alternating warning sounds from the front and rear if there are objects at both bumpers that are closer than 10 inches (25 centimeters). For specific information on the reverse sensing portion of the system, refer to that section. REAR VIEW CAMERA SYSTEM (IF EQUIPPED) WARNING: The rear view camera system is a reverse aid supplement device that still requires the driver to use it in conjunction with the interior and exterior mirrors for maximum coverage. WARNING: Objects that are close to either corner of the bumper or under the bumper, might not be seen on the screen due to the limited coverage of the camera system. 2013 Expedition (exd) Owners Guide gf, 3rd Printing, April 2013 USA (fus)
