FORD 2012 Flex v.2 - Manual (Page 274)

Keep the RSS sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
sensors with sharp objects). If the sensors are covered, it will
affect the accuracy of the RSS.
If your vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles or false alarms.
REARVIEW CAMERA SYSTEM (IF EQUIPPED)
The rearview camera system,
located on the liftgate, provides a
video image, which appears on the
navigation system screen, of the
area behind the vehicle. It adds
assistance to the driver while
reversing or reverse parking the
vehicle.
To use the camera system, place the transmission in R (Reverse); an
image will display on the navigation screen. The area displayed on the
screen may vary according to the vehicle orientation and/or road
condition.
