Universal Remote System
Programming
If equipped, these buttons are in the

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. For calls placed outside the
U.S., Canada, or Puerto Rico, international
rates will apply and may differ based on
landline or mobile phone.
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. Press and release one of the three Universal Remote system buttons to be
programmed. Press and hold the
hand-held transmitter button. Do not
release the hand-held transmitter button
until the indicator light changes from a
slow to a rapid flash or continuous light.
Then release the hand-held transmitter
button. Some garage door openers may require
substitution of Step 2 with the procedure
under
“Radio Signals for 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
indicator light is continuously lit,
or the garage door moves,
programming is complete.
.If the indicator light flashes rapidly
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. Return to the vehicle and firmly press and hold the trained Universal Remote
system button for two seconds and
release. Repeat the “press/hold/release”
sequence up to three times to complete
the training process. The Universal Remote system should now
activate the garage door.
Repeat the process for programming the
two remaining buttons.
Radio Signals for Some Gate Operators
For questions or programming help, see

1-800-355-3515. For calls placed outside the
U.S., Canada, or Puerto Rico, international
rates will apply and may differ based on
landline or mobile phone.
Some radio–frequency laws and 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 change to a rapid flash or
continuous solid-light. Proceed with Step 3
under
“Programming the Universal Remote
System” to complete.

while the signal is being transmitted.
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.

Lighting Features
Entry Lighting
Some exterior lamps turn on briefly at
night, or in areas with limited lighting,
when
Kis pressed on the remote key. After
about 30 seconds the exterior lamps turn off
when any door is opened, the unlock button
on the remote key is pressed, or when the
ignition is switched off. All interior lights
turn on and then the dome and remaining
interior lamps dim to off after 20 seconds.
Entry lighting feature for exterior lighting
can be changed by Vehicle Locator Lights.
See Vehicle Locator Lights under Vehicle
Personalization 0124.
Exit Lighting
Some exterior lamps come on at night, or in
areas with limited lighting, when the driver
door is opened after the ignition is turned
off. The dome lamp comes on after the
ignition is turned off. The exterior lamps and
dome lamp remain on after the door is
closed for a set amount of time, then
automatically turn off.
The exterior lamps turn off immediately by
turning the exterior lamp control off.
The exit lighting for exterior lights can be
changed. See Vehicle Personalization 0124.
Battery Load Management
The vehicle has Electric Power Management
(EPM), which estimates the battery's
temperature and state of charge. It then
adjusts the voltage for best performance
and extended life of the battery.
When the battery's state of charge is low,
the voltage is raised slightly to quickly bring
the charge back up. When the state of
charge is high, the voltage is lowered
slightly to prevent overcharging. The
voltmeter gauge or the voltage display on
the Driver Information Center (DIC), if equipped, may show the voltage moving
up or down. This is normal. If there is a
problem, an alert will be displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for
all vehicles. This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all the power that
is needed for very high electrical loads.
A high electrical load occurs when several of
the following are on, such as: headlamps,
high beams, rear window defogger, climate
control fan at high speed, heated seats,
engine cooling fans, trailer loads, and loads
plugged into accessory power outlets.
EPM works to prevent excessive discharge of
the battery. It does this by balancing the
generator's output and the vehicle's
electrical needs. It can increase engine idle
speed to generate more power, whenever
needed. It can temporarily reduce the power
demands of some accessories.
Normally, these actions occur in steps or
levels, without being noticeable. In rare
cases at the highest levels of corrective
action, this action may be noticeable to the
driver. If so, a DIC message might be

Caution
Using a razor blade or sharp object to
clear the inside rear window can damage
the rear window defogger. Repairs would
not be covered by the vehicle warranty.
Do not clear the inside rear window with
sharp objects.
Remote Start Climate Control Operation :
If equipped with remote start, the climate
control system may run when the vehicle is
started remotely. If equipped with heated or
ventilated seats or a heated steering wheel,
these features may come on during a
remote start. See Remote Vehicle Start 014,
Heated and Ventilated Front Seats 043, and
Heated Steering Wheel 094.
Sensors
The solar sensor, on top of the instrument
panel near the windshield, monitors the
solar heat.
The climate control system uses the sensor
information to adjust the temperature, fan
speed, recirculation, and air delivery mode
for best comfort.
Do not cover the sensor; otherwise the
automatic climate control system may not
work properly.
Rear Climate Control System
The rear climate control system is located
on the rear of the center console storage.
The rear climate settings can be adjusted
with this system.

2. TEMP (Temperature Control)
3. Heated Rear Seats (If Equipped)
4. MODE (Air Delivery Mode Control)
5. AUTO (Automatic Operation)
If the dual automatic climate control system
