{CAUTION:
The Ultrasonic Rear Parking Assist (URPA)
system does not replace driver vision.
It cannot detect:
objects that are below the bumper,
underneath the vehicle, or if they are
too close or far from the vehicle
children, pedestrians, bicyclists, or pets.
If you do not use proper care before and while
backing; vehicle damage, injury, or death
could occur. Even with URPA, always check
behind your vehicle before backing up. While
backing, be sure to look for objects and check
your vehicle’s mirrors.On some vehicles this
display is located near the
passenger side rear
window and can be seen
by looking over your
right shoulder.
If your vehicle has the display, there are three
color-coded lights to provide distance and system
information.
If your vehicle does not have the display and it has
URPA, you will hear the beeps as described in the
following information.
How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R). The rear display will
then brie y illuminate to let you know the system is
working.
URPA operates only at speeds less than 5 mph (8 km/h).
If you are above this speed, the red light on the rear
display will ash.

To be detected, objects must be at least 10 inches
(25.4 cm) off the ground and below liftgate level. Objects
must also be within 8 feet (2.5 m) from your rear
bumper. This distance may be less during warmer or
humid weather.
A single beep will sound the rst time an object is
detected between 20 inches (0.5 m) and 8 feet (2.5 m)
away. Beeping will occur for three seconds when
you are closer than 1 foot (0.3 m) from the object.
The following describes what will occur with the URPA
display as you get closer to a detected object:
Description English Metric
amber light 8 ft 2.5 m
amber/amber lights 40 in 1.0 m
amber/amber/red lights 23 in 0.6 m
amber/amber/red lights
ashing and beep for
three seconds1 ft 0.3 mThe system can be
disabled by pressing the
rear park aid disable button
located next to the radio.
The indicator light will
come on to indicate that
URPA is off.
When the System Does Not Seem to
Work Properly
The driver disables the system.
The parking brake pedal is depressed.
The ultrasonic sensors are not clean. Keep your
vehicle’s rear bumper free of mud, dirt, snow,
ice and slush. For cleaning instructions, see
Washing Your Vehicle on page 5-102.
A trailer was attached to your vehicle, or a bicycle
or an object was hanging out of your liftgate/liftglass
during your last drive cycle, the red light may
illuminate in the rear display. Once the attached
object is removed, URPA will return to normal
operation.

Location information about your vehicle is only available
if the GPS satellite signals are unobstructed and
available.
Your vehicle must have a working electrical system
(including adequate battery power) for the OnStar
equipment to operate. There are other problems OnStar
cannot control that may prevent OnStar from providing
OnStar service to you at any particular time or place.
Some examples are damage to important parts of your
vehicle in an accident, hills, tall buildings, tunnels,
weather or wireless phone network congestion.
Your Responsibility
Increase the radio volume if you cannot hear the OnStar
advisor. If the light next to the OnStar buttons is red,
this means that your system is not functioning properly
and should be checked by your dealer/retailer. If the
light appears clear (no light is appearing), your OnStar
subscription has expired. You can always press the
OnStar button to con rm that your OnStar equipment
is active.

Universal Home Remote System
Operation (With Three Round LED)
Your vehicle may have the Universal Home Remote
System. If there are three round Light Emitting Diode
(LED) indicator lights above the Universal Home Remote
buttons, follow the instructions below.
This system provides a way to replace up to three
remote control transmitters used to activate devices
such as garage door openers, security systems,
and home automation devices.
Do not use this system with any garage door opener
that does not have the stop and reverse feature.
This includes any garage door opener model
manufactured before April 1, 1982.
Read the instructions completely before attempting to
program the transmitter. Because of the steps involved,
it may be helpful to have another person available to
assist you in programming the transmitter.Be sure to keep the original remote control transmitter
for use in other vehicles, as well as, for future
programming. You only need the original remote control
transmitter for Fixed Code programming. It is also
recommended that upon the sale or lease termination of
the vehicle, the programmed buttons should be
erased for security purposes. See “Erasing Universal
Home Remote Buttons” later in this section.
When programming a garage door, it is advised to park
outside of the garage. Be sure that people and
objects are clear of the garage door or security device
you are programming.Programming Universal Home
Remote — Rolling Code
If you have questions or need help programming the
Universal Home Remote System, call 1-866-572-2728 or
go to www.learcar2u.com.
Most garage door openers sold after 1996 are Rolling
Code units.
Programming a garage door opener involves
time-sensitive actions, so read the entire procedure
before you begin. If you do not follow these actions, the
device will time out and you will have to repeat the
procedure.

3. Immediately return to your vehicle. Press and hold
the Universal Home Remote button that you would
like to use to control the garage door until the
garage door moves. The indicator light, above the
selected button, should slowly blink. You may
need to hold the button from ve to 20 seconds.
4. Immediately, within one second, release the button
when the garage door moves. The indicator light
will blink rapidly until programming is complete.
5. Press and release the same button again. The
garage door should move, con rming that
programming is successful and complete.
To program another Rolling Code device such as an
additional garage door opener, a security device,
or home automation device, repeat Steps 1 through 5,
choosing a different function button in Step 3 than
what you used for the garage door opener.
If these instructions do not work, you probably have a
Fixed Code garage door opener. Follow the
Programming instructions that follow for a Fixed Code
garage door opener.Programming Universal Home

2. Write down the eight to 12 switch settings from left
to right as follows:
When a switch is in the up position, write “Left.”
When a switch is in the down position, write
