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 these 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 help programming
the Universal Remote system, call
1-800-355-3515 or see
www.homelink.com.
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
changes from a slow to a rapid
flash. 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

INSTRUMENTS AND CONTROLS 181
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
call 1-800-355-3515 or see
www.homelink.com.
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
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.”

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 button on the end of the
turn signal lever when the exterior
lamp control is in the AUTO or
2
position. The blue high-beam on light
appears on the instrument cluster
when the high beams are on.
Driving with IntelliBeam
The system only activates the high
beams when driving over 40 km/h
(25 mph).
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 high/low-beam changer or
the flash-to-pass feature. If this
happens, press the button on the
end of the turn signal lever when
the exterior lamp control is in the
AUTO or
2position. The
instrument cluster light will come
on to indicate the IntelliBeam is
reactivated.
See Headlamp High/Low-Beam
Changer 0185 and Flash-to-Pass
0 185. 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.
