How The System Works - Cadillac 2004 Seville Owner's Manual

CAUTION: (Continued)
So, unless you check carefully behind you
before and when you back up, you could strike
children, pedestrians, bicyclists or pets behind
you, and they could be injured or killed.
Whether or not you are using Rear Park Assist,
always check carefully behind your vehicle
before you back up and then watch closely as
you do.
The URPA display is
located inside the vehicle,
above the rear window.
It has three color-coded
lights that can be seen
through the rearview mirror
or by turning around.

How the System Works

URPA comes on automatically when the shift lever is
moved into REVERSE (R). When the system comes on,
the three lights on the display will briefly illuminate 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 the
system does not work at this speed.
The first time an object is detected while in
REVERSE (R), a chime will sound and the following will
occur in sequence, depending on the distance from
the object:
•
At 5 feet (1.5 m) a chime will sound and one amber
light will be lit;
•
at 40 inches (1.0 m) both amber lights will be lit;
•
at 20 inches (0.5 m) a continuous chime will sound
and all three lights (amber/amber/red) will be lit; and
•
at 1 foot (0.3 m) a continuous chime will sound and
all three lights (amber/amber/red) will flash.
URPA can detect objects 3 inches (7.6 cm) and wider,
and at least 10 inches (25.4 cm) tall, but it cannot detect
objects that are above trunk level. In order for the
rear sensors to recognize an object, it must be within
operating range.
