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

146 Instruments and Controls
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 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 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.”

Battery Load
Management
The vehicle has Electric Power
Management (EPM) that 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. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), you may see the
