overhead console.
This system can replace up to three
remote control transmitters used to
activate devices such as garage
door openers, security systems, and
home automation devices. These

instructions refer to a garage door
opener, but can be used for other
devices.
Do not use the Universal Remote
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 programming the Universal
Remote system. It may help to have
another person assist with the
programming process.
Keep the original hand-held
transmitter for use in other vehicles
as well as for future programming.
Erase the programming when
vehicle ownership is terminated.
See“Erasing Universal Remote
System Buttons” later in this
section.
To program a garage door opener,
park outside directly in line with and
facing the garage door opener
receiver. Clear all people and
objects near the garage door. Make sure the hand-held transmitter
has a new battery for quick and
accurate transmission of the
radio-frequency signal.
Programming the Universal
Remote System
For questions or programming help,
see www.homelink.com/gm or call
1-800-355-3515.
Programming involves
time-sensitive actions, and may time
out causing the procedure to be
repeated.
To program up to three devices:
1. Hold the end of the hand-held transmitter about 3 to 8 cm
(1 to 3 in) away from the
Universal Remote system
buttons with the indicator light
in view. The hand-held
transmitter was supplied by the
manufacturer of the garage
door opener receiver.
2. At the same time, press and hold both the hand-held
transmitter button and one of
the three Universal Remote system buttons to be used to
operate the garage door. Do
not release either button until
the indicator light goes from a
slow to a rapid flashing light.
Then release both buttons.
Some garage door openers
may require substitution of
Step 2 with the procedure
under
“Radio Signals for
Canada and Some Gate
Operators” later in this section.
3. Press and hold the newly programmed Universal Remote
system button for five seconds
while watching the indicator
light and garage door
activation.
.If the indicator light stays on
continuously or the garage
door moves when the
button is pressed, then
programming is complete.
There is no need to
complete Steps 4–6.
. If the indicator light does
not come on or the garage
door does not move, a

second button press may
be required. For a second
time, press and hold the
newly programmed button
for five seconds. If the light
stays on or the garage door
moves, programming is
complete.
. If the indicator light blinks
rapidly for two seconds,
then changes to a solid light
and the garage door does
not move, continue with
programming Steps 4–6.
Learn or Smart Button
4. After completing Steps 1–3, locate the Learn or Smart
button inside the garage on the
garage door opener receiver. The name and color of the
button may vary by
manufacturer.
5. Press and release the Learn or Smart button. Step 6 must be
completed within 30 seconds of
pressing this button.
6. Inside the vehicle, press and hold the newly programmed
Universal Remote system
button for two seconds and
then release it. If the garage
door does not move or the
lamp on the garage door
opener receiver does not flash,
press and hold the same
button a second time for
two seconds, then release it.
Again, if the door does not
move or the garage door lamp
does not flash, press and hold
the same button a third time for
two seconds, then release it.
The Universal Remote system
should now activate the
garage door. Repeat the process for
programming the two remaining
buttons.
Radio Signals for Canada and
Some Gate Operators
For questions or programming help,
see www.homelink.com/gm or call
1-800-355-3515.
Canadian radio-frequency laws and
some U.S. gate operators require
transmitter signals to time out or quit
after several seconds of
transmission. This may not be long
enough for the Universal Remote
system to pick up the signal during
programming.
If the programming did not work,
replace Step 2 under
“Programming
the Universal Remote System” with
the following:
Press and hold the Universal
Remote system button while
pressing and releasing the
hand-held transmitter button every
two seconds until the signal has
been successfully accepted by the
Universal Remote system. The
Universal Remote system indicator

light will flash slowly at first and then
rapidly. Proceed with Step 3 under
“Programming the Universal Remote
System”to complete.
Universal Remote System

Erasing Universal Remote
System Buttons
Erase all programmed buttons when
vehicle ownership is terminated.
To erase:
1. Press and hold the two outside buttons until the indicator light
begins to flash. This should
take about 10 seconds.
2. Release both buttons.
Reprogramming a Single
Universal Remote System
Button
To reprogram any of the system
buttons: 1. Press and hold any one of the buttons. Do not release the
button.
2. The indicator light will begin to flash after 20 seconds. Without
releasing the button, proceed
with Step 1 under
“Programming the Universal
Remote System.”

L :This position allows selection of
a range of gears appropriate for
current driving conditions.
If equipped, see “Range Selection
Mode” underManual Mode 0223.
Caution
Spinning the tires or holding the
vehicle in one place on a hill
using only the accelerator pedal
may damage the transmission.
The repair will not be covered by
the vehicle warranty. If the vehicle
is stuck, do not spin the tires.
When stopping on a hill, use the
brakes to hold the vehicle in
place.
Normal Mode Grade Braking
This mode is enabled when the
vehicle is started, but is not enabled
in Range Selection Mode. It assists
in maintaining desired vehicle
speeds when driving on downhill
grades by using the engine and
transmission to slow the vehicle. The first time the system engages
for each ignition cycle, a DIC
message will be displayed.
To disable or enable Normal Mode
Grade Braking within the current
ignition cycle, press and hold the
Tow/Haul button for five seconds.
When the button is released, the
requested mode change is made.
A DIC message displays.
For other forms of grade braking,
see
Tow/Haul Mode 0225 and
Cruise Control 0237.
Kickdown Mode
The accelerator pedal provides an
additional downshift after pressing
through the kickdown feature.
It requires extra pedal pressure near
the end of its travel to engage.
Manual Mode
Range Selection Mode
If equipped, Range Selection Mode
helps control the vehicle's
transmission and vehicle speed
while driving downhill or towing a
trailer by letting you select a desired
range of gears.
To use this feature:
1. Move the shift lever to L (Manual Mode).
2. Press the plus/minus buttons on the shift lever to select the
desired range of gears for
current driving conditions.
Hold the plus/minus buttons on the
shift lever to select the highest or
lowest range available for the
current vehicle speed.

system, and on the type of trailer
brakes detected. This available
power output to the trailer brakes
can be adjusted to a wide range of
trailering situations.
The ITBC system is integrated with
the vehicle’s brake, antilock brake,
and StabiliTrak systems. In trailering
conditions that cause the vehicle’s
antilock brake or StabiliTrak
systems to activate, power sent to
the trailer's brakes will be
automatically adjusted to minimize
trailer wheel lock-up. This does not
imply that the trailer has StabiliTrak.
If the vehicle’s brake, antilock brake,
or StabiliTrak systems are not
functioning properly, the ITBC
system may not be fully functional
or may not function at all. Make sure
all of these systems are fully
operational to ensure full
functionality of the ITBC system. The ITBC system is powered
through the vehicle's electrical
system. Turning the ignition off will
also turn off the ITBC system. The
ITBC system is fully functional only
when the ignition is in on.
{Warning
Connecting a trailer that has an
air brake system may result in
reduced or complete loss of trailer
braking. There may be an
increase in stopping distance or
trailer instability which could
result in personal injury or
damage to the vehicle, trailer,
or other property. Use the ITBC
system only with electric or
electric over hydraulic trailer
brakes.
