To be detected, objects must be at least 10 inches (25.4 cm) off the ground and below trunk level. Objects must also be within 5 feet (1.5 m) from your rear bumper. This distance may be less during warmer or humid weather. A single beep will sound the first time an object is detected between 20 inches (0.5 m) and 5 feet (1.5 m) away. Repeated beeping will occur when you are closer than 20 inches (0.5 m) from the object. The following describes what will occur with the URPA display as you get closer to a detected object: Description amber light amber/amber lights amber/amber/red lights/continuous beep amber/amber/red lights flashing and continuous beep English 5 ft 40 in 20 in 1 ft Metric 1.5 m 1.0 m 0.5 m 0.3 m When the System Does Not Seem to Work Properly • The ultrasonic sensors are not clean, a red URPA display light may illuminate when the vehicle is in REVERSE (R). Keep your rear bumper free of mud, dirt, snow, ice and slush. For cleaning instructions, see Washing Your Vehicle on page 6-83. • A trailer was attached to your vehicle, or a bicycle or an object was hanging out of your trunk during your last drive cycle, the red light may illuminate. Once the attached object is removed, URPA will return to normal operation. • The vehicle's bumper is damaged. Take the vehicle to your dealer/retailer to repair the system. • Other conditions may affect system performance, such as vibrations from a jackhammer or the compression of air brakes on a very large truck. If the system is still disabled, after driving forward at least 15 mph (25 km/h), take your vehicle to your dealer/retailer. 2-40
