How the System Works when Backing When backing, UFRPA detects objects close to the front and rear bumpers. The first time an object is detected a single chime will sound. If an object is detected at a REVERSE (R) speed of less than 5 mph (8 km/h), or if you are already within an 8 ft (2.5 m) distance to a detected object when the system first comes on, the following describes what will occur according to your distance from an object located behind the vehicle: • At distances between 40 inches (1 m) and 8 ft (2.5 m), a single amber light will be lit. • At distances between 23 inches (0.6 m) and 40 inches (1 m), both amber lights will be lit. • At distances between 12 inches (0.3 m) and 23 inches (0.6 m), all three lights (amber/ amber/red) will be lit. • At distances less than 12 inches (0.3 m), a chime will sound for a short time and all three lights (amber/amber/red) will be lit and flashing. When you are backing the vehicle and objects are detected at the same time near both the front and rear bumpers, both color-coded light displays will notify you of objects close to each bumper. If there are objects detected near both bumpers, the beeps will only be sounded to notify that objects are close to the rear bumper. However, if while you are backing and an object comes within 1 ft (0.3 m) of the front bumper, and at the same time there is another object further than 1 ft (0.3 m) from the rear bumper, then the beeps will only be sounded to notify you of the closer object that is near the front bumper. 199
