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 3 mph (5 km/h).
If the vehicle is above this speed, the red light on the rear
display will flash.
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 the 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. Beeping will occur when the vehicle is closer
than 20 inches (0.5 m) from the object.
The following describes what will occur with the URPA
display as the vehicle gets closer to a detected object:

When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporary
condition, a red light will be shown on the rear URPA
display when the shift lever is moved into R (Reverse).
This occurs under the following conditions:
• The ultrasonic sensors are not clean. Keep the
vehicle’s rear bumper free of mud, dirt, snow,
ice and slush. For cleaning instructions, see
Washing Your Vehicle on page 6-77.
• An object was hanging out of the trunk during the
last drive cycle. Once the 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 the vehicle to your
dealer/retailer.
