126 INSTRUMENTS AND CONTROLS
Programming the Universal
Remote System
Programming involves time-sensitive
actions and may time out, requiring
the procedure to be repeated. Read
these instructions completely before
programming the Universal Remote
system. It may help to have another
person assist with the programming
process.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 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 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
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.

INSTRUMENTS AND CONTROLS 127
The Universal Remote system should
now activate the garage door. Repeat
the process for programming the
remaining two buttons.
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.
Radio Signals for Some Gate
Operators
Some gate operators and
radio-frequency laws 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.
Universal Remote System
Operation
Using the Universal Remote
System
Press and hold the appropriate
Universal Remote system button for at
least one-half second. The indicator
light will come on 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.
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.”

The blue high-beam on light appears
on the instrument cluster when the
high beams are on. There is a sensor near the top center
of the windshield that automatically
controls the system. Keep this area of
the windshield clear of debris to allow
for best system performance.
The high-beam headlamps remain on,
under the automatic control, until one
of the following situations occurs:
.The system detects an approaching
vehicle's headlamps.
.The system detects a preceding
vehicle's taillamps.
.The outside light is bright enough
that high-beam headlamps are not
required.
.The vehicle's speed drops below
20 km/h (12 mph).
.The IntelliBeam system is disabled
by the button on the turn signal
lever. If this happens, press
bon

system is reactivated. The high beams may not turn off
automatically if the system cannot
detect another vehicle's lamps because
of any of the following:
.The other vehicle's lamps are
missing, damaged, obstructed from
view, or otherwise undetected.
.The other vehicle's lamps are
covered with dirt, snow, and/or road
spray.
.The other vehicle's lamps cannot be
detected due to dense exhaust,
smoke, fog, snow, road spray, mist,
or other airborne obstructions.
.The vehicle's windshield is dirty,
cracked, or obstructed by something
that blocks the view of the light
sensor.
.The vehicle is loaded such that the
front end points upward, causing
the light sensor to aim high and not
detect headlamps and taillamps.
.The vehicle is being driven on
winding or hilly roads.
The automatic high-beam headlamps
may need to be disabled if any of the
above conditions exist.
