Features and Controls How the System Works URPA comes on automatically when the shift lever is moved into R (Reverse). The rear display briefly illuminates to indicate the system is working. URPA operates only at speeds less than 5 mph (8 km/h). If the vehicle is above this speed, the red light on the rear display flashes. To be detected, objects must be at least 10 inches (25.4 cm) off the ground and below liftgate level. Objects must also be within 8 feet (2.5 m) from the rear bumper. This distance may be less during warmer or humid weather. A single beep sounds the first time an object is detected. Beeping may occur beginning at 23 inches (0.6 m). Beeping occurs for a short time when the vehicle is closer than 23 inches (0.6 m) and again at 1 foot (0.3 m) from the object. 2-37 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 amber/amber/red lights flashing The system can be disabled through the Driver Information Center (DIC). See "Park Assist" under DIC Operation and Displays (With DIC Buttons) on page 3-45 or DIC Operation and Displays (Without DIC Buttons) on page 3-51 for more information.
