How The System Works - Cadillac 2007 SRX Owner's Manual

How the System Works

URPA comes on automatically when the shift lever
is moved into REVERSE (R) and the vehicle
speed is less than 3 mph (5 km/h). When
the system turns on, the three lights on the display
will illuminate for one and a half seconds to let
you know that the system is working. If your
vehicle is moving in REVERSE (R) at a speed
greater than 3 mph (5 km/h), the red light will flash
to remind you that the system does not work at
a speed greater than 3 mph (5 km/h).
The URPA display is
located inside the
vehicle, above the
liftgate glass. It
has three color-coded
lights that can be
seen through the
rearview mirror or by
turning around.
If an object is detected at a REVERSE (R) speed
of less than 3 mph (5 km/h), one of the following
will occur:

A chime will sound the first time an object is
detected between 20 inches (0.5 m) and 5 feet
(1.5 m) away.
URPA cannot detect objects that are above liftgate
level. In order for the rear sensors to recognize
an object, it must be within detection range behind
the vehicle.
