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

154 Instruments and Controls
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
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 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.
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

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

IntelliBeam System
If equipped, this system turns
the vehicle's high-beam
headlamps on and off
according to surrounding
traffic conditions. The system turns the
high-beam headlamps on when
it is dark enough and there is
no other traffic present.
This light
bcomes on in the
instrument cluster when the
IntelliBeam system is enabled.
Turning On and Enabling
IntelliBeam
To enable the IntelliBeam
system, press the end of the
turn signal lever when it is
dark outside and the exterior
lamp control is in AUTO or
2.
Driving with IntelliBeam
The system only activates the
high beams when driving over
40 km/h (25 mph). 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 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 the end of
the turn signal lever when
the exterior lamp control is
in the AUTO or
2position to
reactivate the IntelliBeam
system. The instrument
cluster light will come on to
indicate the IntelliBeam
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.

Daytime Running
Lamps (DRL)
DRL can make it easier for
others to see the front of your
vehicle during the day. Fully
functional DRL are required on
all vehicles first sold in
Canada.
The dedicated DRL will come
on when all of the following
conditions are met:
.The ignition is on.
.The exterior lamp control is
in AUTO.
.The light sensor determines
it is daytime.
.The parking brake is
released or the vehicle is not
in P (Park).
When the DRL are on, the
taillamps, sidemarker lamps,
and other lamps will not be on.
The DRL turn off when the
headlamps are turned to
Oor
the ignition is off. For vehicles first sold in Canada, the DRL
can only be turned off when
the vehicle is parked.
Automatic Headlamp
System
When the exterior lamp
control is set to AUTO and it is
dark enough outside, the
headlamps come on
automatically.
There is a light sensor on top
of the instrument panel. Do
not cover the sensor.
The system may also turn on
the headlamps when driving
through a parking garage or
tunnel.
If the vehicle is started in a
dark garage, the automatic
headlamp system comes on
immediately. If it is light
outside when the vehicle
leaves the garage, there is a
slight delay before the
automatic headlamp system
changes to the Daytime
Running Lamps (DRL). During
that delay, the instrument
cluster may not be as bright as
usual. Make sure the
instrument panel brightness
control is in the full bright
position. See Instrument Panel
Illumination Control
0161.
When it is bright enough
outside, the headlamps will
turn off or may change
to DRL.
The automatic headlamp
system turns off when the
exterior lamp control is turned
to
Oor the ignition is off.
