Universal Home Remote System
Operation (With One Triangular LED)
Your vehicle may have the Universal Home
Remote System. If there is one triangular Light
Emitting Diode (LED) above the Universal
Home Remote buttons, follow the instructions
below. If your vehicle has three round LED above
the Universal Home Remote buttons, follow the
instructions under Universal Home Remote System
Operation (with three round LED).
Do not use the Universal Home Remote with any
garage door opener that does not have the stop
and reverse feature. This includes any garage door

Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to time out or quit after several seconds
of transmission. This may not be long enough
for Universal Home Remote to pick up the signal
during programming. Similarly, some U.S. gate
operators are manufactured to time out in
the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator or garage door
opener by using the “Programming Universal
Home Remote” procedures, regardless of where
you live, replace Step 3 under “Programming
Universal Home Remote” with the following:
Continue to press and hold the Universal Home
Remote button while you press and release every
two seconds (cycle) the hand-held transmitter
button until the frequency signal has been
successfully accepted by the Universal Home
Remote. The Universal Home Remote indicator
light will ash slowly at rst and then rapidly.
Proceed with Step 4 under “Programming
Universal Home Remote” to complete.
Using Universal Home Remote
Press and hold the appropriate Universal Home
Remote button for at least half of a second.
The indicator light will come on while the signal is
being transmitted.
Erasing Universal Home Remote
Buttons
To erase programming from the three Universal
Home Remote buttons do the following:
1. Press and hold down the two outside buttons
until the indicator light begins to ash, after
20 seconds. Do not hold the two outside
buttons for longer than 30 seconds.
2. Release both buttons.
The Universal Home Remote is now in the training
(learning) mode and can be programmed at any
time beginning with Step 2 under “Programming
Universal Home Remote” shown earlier in
this section.
Individual buttons cannot be erased, but they can
be reprogrammed. See “Reprogramming a
Single Universal Home Remote Button” following
this section.

vehicle has been off for more than three hours.
Outside Air Temperature Display
A new outside temperature reading will be
displayed if the vehicle has been off for more than
three hours. If the vehicle has been off for less
than three hours, the old temperature reading may
be displayed because underhood heat is
affecting the true outside temperature. Underhood
heat can also affect the outside temperature
while the engine is running. It may also take
several minutes of driving before the display
updates to the actual outside temperature.
