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 ¯ash.
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 ¯ash red, indicating that there is a problem.
The light will also ¯ash 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 ¯ash until the trailer or the
object is removed or the tailgate is raised and your
vehicle is driven forward at least 15 mph (25 km/h).
It may also ¯ash red if the ultrasonic sensors are not
kept clean.

Delayed Locking
If your DIC does not have this feature, you can still
program the delayed locking feature. SeeDelayed
Locking on page 2-9for more information.
When locking the doors with the power lock switch or
the keyless entry transmitter and a door or the liftgate is
open, the delayed locking feature will delay locking
the doors and tailgate until ®ve seconds after the last
door is closed.

button while DELAYED LOCKING is displayed on the
DIC. Pressing the select button will scroll through
the following choices:
DELAYED LOCKING ON:The doors will not lock until
®ve seconds after the last door or the liftgate is
closed. You will hear three chimes to signal that the
delayed locking feature is in use. You can temporarily
override delayed locking by pressing the lock button
on the door or keyless entry transmitter a second time.

At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag
system does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace
blade inserts that appear worn or damaged or that
streak or miss areas of the windshield. Also see
Cleaning the Outside of Your Vehicle on page 5-96.
Spare Tire Check
At least twice a year, after the monthly in¯ation check of
the spare tire determines that the spare is in¯ated to the
correct tire in¯ation pressure, make sure that the spare
tire is stored securely. Push, pull, and then try to rotate or
turn the tire. If it moves, use the wheel wrench/ratchet to
tighten the cable. See
Changing a Flat Tire on page 5-76.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. See
Part D: Recommended Fluids and
Lubricants on page 6-17.
Automatic Transmission Check
Check the transmission ¯uid level; add if needed.
SeeAutomatic Transmission Fluid on page 5-21.
A ¯uid loss may indicate a problem. Check the system
and repair if needed.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
speci®ed in Part D.
Body Lubrication Service
Lubricate all hood latch assembly, secondary latch,
pivots, spring anchor, release pawl, rear compartment
hinges, outer tailgate handle pivot points, latch bolt,
fuel door hinge and folding seat hardware. Part D tells
you what to use. More frequent lubrication may be
required when exposed to a corrosive environment.
