How the System Works

URPA comes on automatically when the shift lever is
moved into REVERSE (R). The rear display will then
briefly illuminate to let you know the system is working.
URPA operates only at speeds less than 3 mph (5 km/h).
If you are 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 liftgate 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:

While the system is disabled, an indicator light will be lit

display if the switch is in the off position.
