Ultrasonic Rear Parking Assist (Urpa); How The System Works - Cadillac 2005 XLR Owner's Manual

Ultrasonic Rear Parking Assist
(URPA)
Ultrasonic Rear Parking Assist can help you to
determine how close an object is to your rear bumper
within a given area, making parking easier.
CAUTION:
{
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully before
backing up. The system does not operate above
typical backing speeds of 3 mph (5 km/h) while
parking. And, the system does not detect
objects that are more than 5 feet (1.5 meters)
behind the vehicle.
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.

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 comes on,
the three lights on the display will illuminate to let you
know that the system is working. URPA senses
how close your vehicle is to an object. The distance is
determined by the four ultrasonic sensors located on the
rear bumper.
The URPA display is
located inside the vehicle,
below the rear window.
It has three color-coded
lights that can be seen
through the rearview mirror
or by turning around.
