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. When you shift into REVERSE (R) and an
object is detected, 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 the center of the Cadillac crest
badge on the tailgate. In order for the rear sensors to
recognize an object, it must be within operating range.
NOTICE:
The URPA system will not work correctly with
the tailgate lowered. You could damage your
vehicle by backing into an object before URPA
detects it. Turn off the URPA system when
driving with the tailgate lowered.

If the URPA Display Flashes Red
If the URPA system is not functioning properly, the
display will flash red, indicating that there is a problem.
The light will also flash red while driving if any of the
following conditions exist:
A trailer or trailer
-hitch ball mount is attached to
your vehicle.
A bicycle or object is on the back of, or hanging out
the cargo area.
If the tailgate is lowered.
If your vehicle is moving in REVERSE (R) at a
speed greater than 3 mph (5 km/h).
The light will continue to flash until the trailer or the
object is removed or the tailgate raised and your vehicle
is driven forward at least 15 mph (25 km/h).It may also flash red if the ultrasonic sensors are not
kept clean.
So be sure to keep your rear bumper free of mud, dirt,
snow, ice and slush or materials such as paint or the
system may not work properly. If after cleaning the rear
bumper and driving forward at least 15 mph (25 km/h),
the display continues to flash red, see your dealer. For
cleaning instructions, see ªCleaning Your Vehicleº in
the Index.
Other conditions that may affect system performance
include things like the vibrations from a jackhammer or
the compression of air brakes on a very large truck.
As always, drivers should use care when backing up a
vehicle. Always look behind you, being sure to check
for other vehicles, obstructions and blind spots.

control ring allows for more volume compensation
at faster vehicle speeds. Then, as you drive, SCV
automatically increases the volume, as necessary, to
overcome noise at any speed. The volume level should
always sound the same to you as you drive. If you don't
want to use SCV, turn the control ring counterclockwise.

Cassette Tape Messages
If an error occurs while trying to play a cassette tape,
it could be for one of the following reasons:
The cassette tape is tight and the cassette player
cannot turn the hubs of the tape. Hold the cassette
tape with the open end down and try turning the
right hub counterclockwise with a pencil. Flip the
tape over and repeat. If the hubs do not turn easily,
your cassette tape may be damaged and should not
be used in the player. Try a new tape to be sure your
player is working properly.
The cassette tape is broken. (Check to see if your
tape is broken. Try a new tape.)
CLN (Clean): If this message appears on the display,
the cassette tape player needs to be cleaned. It will still
play tapes, but you should clean it as soon as possible to
prevent damage to the tapes and player. See ªCare of
Your Cassette Tape Playerº in the Index.
If any error occurs repeatedly or if an error can't be
corrected, contact your dealer.CD Adapter Kits
It is possible to use a portable CD player adapter kit
with your cassette tape player after activating the bypass
feature on your tape player.

is pressed.
3-15 Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen to and
control any of the music sources: AM FM, cassette tapes
and CDs, through the Rear Seat Audio (RSA) controller.
However, the rear seat passengers can only control the
music sources that the front seat passengers are not
listening to. For example, rear seat passengers may
listen to a cassette tape through headphones while the
driver listens to the radio through the front speakers.
The rear seat passengers have control of the volume for
each set of headphones. The rear speakers will be muted
when the RSA power is turned on. You may operate the
RSA functions even when the main radio is off.The following functions are controlled by the buttons on
the main radio:
REAR DSPL (Rear Display): When the main radio
is turned on, press this button to turn on the RSA
display on the main radio. Press it again to turn the
RSA display off.
PR (Power Rear): Press this button, on the main radio,
to turn RSA on or off. The light to the right of the button
will illuminate to indicate that RSA is on.
The following functions are controlled by the RSA
system buttons:
PWR (Power): Press this button to turn RSA on or off.
AM FM: Press this button to switch between AM, FM1
and FM2. If the front passengers are already listening to
AM
-FM, the RSA controller will not switch between the
bands and cannot change the frequency.
SEEK : While listening to the radio, press the
up arrow to tune to the next station and stay there.
Press the down arrow to tune to the previous station
and stay there. The sound will mute while seeking.
The SEEK button is inactive if the AM FM mode on
the front radio is in use.
