How The System Works - Cadillac 2008 CTS Owner's Manual

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 5 mph
(8 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 trunk level. Objects
must also be within 8 feet (2.5 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 8 feet (2.5 m)
away. Beeping will occur for three seconds when
you are closer than 1 foot (0.3 m) from the object.

The following describes what will occur with the URPA
display as you get closer to a detected object:
