When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporary
condition, the message PARKING ASSIST OFF will be
displayed on the DIC and a red light will be shown on the
rear URPA display when the shift lever is moved into
R (Reverse). This occurs under the following conditions:
The driver disables the system.
The parking brake pedal is depressed.
The ultrasonic sensors are not clean. Keep the
vehicle’s rear bumper free of mud, dirt, snow, ice and
slush. For cleaning instructions, seeWashing Your
Vehicle on page 5-118.
A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the tailgate during the
last drive cycle, the red light may illuminate in the
rear display. Once the attached object is removed,
URPA will return to normal operation.
A tow bar is attached to the vehicle.
The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled, after driving forward at
least 15 mph (25 km/h), take the vehicle to your
dealer/retailer.

How OnStar Service Works
Your vehicle’s OnStar system has the capability
of recording and transmitting vehicle information.
This information is automatically sent to an OnStar
Call Center at the time of an OnStar button press,
Emergency button press or if your airbags or AACN
system deploys. The vehicle information usually includes
your GPS location and, in the event of a crash, additional
information regarding the accident that your vehicle has
been involved in (e.g. the direction from which your
vehicle was hit). When you use the Virtual Advisor feature
of OnStar Hands-Free Calling, your vehicle also sends
OnStar your GPS location so that we can provide you
with location-based services.
OnStar service cannot work unless your vehicle is in a
place where OnStar has an agreement with a wireless
service provider for service in that area. OnStar service
also cannot work unless you are in a place where the
wireless service provider OnStar has hired for that area
has coverage, network capacity and reception when the
service is needed, and technology that is compatible
with the OnStar service. Not all services are available
everywhere, particularly in remote or enclosed areas,
or at all times.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.

Operation (With Three Round LED)
This 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.

Read the instructions completely before attempting to
program the transmitter. Because of the steps involved,
it may be helpful to have another person assist with
programming the transmitter.
Be sure to keep the original remote control
transmitter for use in other vehicles, as well as,
for future programming. Only the original remote
control transmitter is needed for Fixed Code
programming. The programmed buttons should be
erased when the vehicle is sold or the lease ends.
See “Erasing Universal Home Remote Buttons”
later in this section.
Park the vehicle outside of the garage when
programming a garage door. Be sure that people
and objects are clear of the garage door or gate
that is being programmed.Programming Universal Home
Remote — Rolling Code
For questions or 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 starting. Otherwise, the device will time out
and the procedure will have to be repeated.
To program up to three devices:
1. From inside the vehicle, press the two outside
buttons at the same time for one to two seconds,
and immediately release them.
2-72
Page 167 of 596
2. Locate in the garage, the garage door opener
receiver (motor-head unit). Locate the “Learn” or
“Smart” button. It can usually be found where the
hanging antenna wire is attached to the motor-head
unit and may be a colored button. Press this button.
After pressing this button, complete the following
steps in less than 30 seconds.3. Immediately return to the vehicle. Press and hold
the Universal Home Remote button that will be used
to control the garage door until the garage door
moves. The indicator light, above the selected
button, should slowly blink. This button may
need to be held for up 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 was used for the garage door opener.
If these instructions do not work, the garage door
opener is probably a Fixed Code unit. Follow the
Programming instructions that follow for a Fixed Code
garage door opener.

Programming Universal Home
Remote — Fixed Code
For questions or help programming the Universal
Home Remote System, call 1-866-572-2728 or go
to www.learcar2u.com.
Most garage door openers sold before 1996 are Fixed
Code units.
Programming a garage door opener involves
time-sensitive actions, so read the entire procedure
before starting. Otherwise, the device will time out
and the procedure will have to be repeated.To program up to three devices:
1. To verify that the garage door opener is a Fixed
Code unit, remove the battery cover on the hand
held transmitter supplied by the manufacturer of the
garage door opener motor. If there are a row of dip
switches similar to the graphic above, the garage
door opener is a Fixed Code unit. If you do not
see a row of dip switches, return to the previous
section for Programming Universal Home
Remote – Rolling Code.
Your hand held transmitter can have between
eight to 12 dip switches depending on the brand
of transmitter.
2-74
Page 169 of 596
The garage door opener receiver (motor head unit)
could also have a row of dip switches that can be
used when programming the Universal Home
Remote. If the total number of switches on the motor
head and hand held transmitter are different, or if the
dip switch settings are different, use the dip switch
settings on the motor head unit to program the
Universal Home Remote. The motor head dip switch
settings can also be used when the original hand
held transmitter is not available.
The panel of switches might not appear exactly as
they do in the examples above, but they should
be similar.
The switch positions on the hand-held transmitter
could be labeled, as follows:
A switch in the up position could be labeled
as “Up,” “+,” or “On.”
A switch in the down position could be labeled
as “Down,” “−,” or “Off.”
A switch in the middle position could be labeled
as “Middle,” “0,” or “Neutral.” Example of Eight Dip Switches with Two Positions
Example of Eight Dip Switches with Three Positions

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
“Right.”
If a switch is set between the up and down
position, write “Middle.”
The switch settings written down in Step 2 now
become the button strokes to be entered into the
Universal Home Remote in Step 4. Be sure to
enter the switch settings written down in Step 2,
in order from left to right, into the Universal Home
Remote, when completing Step 4.
3. From inside your vehicle, rst rmly press all three
buttons at the same time for about three seconds.
Release the buttons to put the Universal Home
Remote into programming mode.4. The indicator lights will blink slowly. Enter each
switch setting from Step 2 into your vehicle’s
Universal Home Remote. You will have two and
one-half minutes to complete Step 4. Now press
one button on the Universal Home Remote for each
switch setting as follows:
If you wrote “Left,” press the left button in the
vehicle.
If you wrote “Right,” press the right button in the
vehicle.
If you wrote “Middle,” press the middle button in
the vehicle.
