How The System Works - GMC 2008 Acadia Owner's Manual

URPA uses three color-coded lights to provide distance
and system information.

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.
2-46
The display is located in
the headliner and can be
seen by looking over
your right shoulder.
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 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:
