If the vehicle is traveling faster then 8 km/h (5 mph) in reverse, the red light on the rear display flashes. Objects must be at least 25.4 cm (10 in.) off the ground and below trunk level, and within 2.4m (8 ft.) from the rear bumper to be detected. The distance may be less during warmer or humid weather. A single beep sounds the first time an object is detected between 1.0 m (40 in.) and 2.4m (8 ft.) away. Beeping occurs continuously when the vehicle is 0.6 m (23 in.) or closer to an object. 8-45 The following describes how the URPA display lights appear as the vehicle gets closer to a detected object: Description amber light amber/amber lights amber/amber/red lights and continuous beeping for five seconds amber/amber/red lights flashing and continuous beeping for five seconds Metric 2.4 m 1.0 m 0.6 m English 8 ft. 40 in. 23 in. 0.3 m 1 ft.
