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

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.

Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions
allow you to signal a turn or a lane change.
To signal a turn, move the lever all the way up or
down. When the turn is nished, the lever will
return automatically.
To signal a lane change, raise or lower the lever
for less than one second until the arrow starts
to ash. This will cause the turn signals to

times if tow-haul mode is active. Holding the turn
signal lever for more than one second will
cause the turn signals to ash until you release
the lever. The lever will return by itself when
it is released.

When the weather is cool or damp, operating the
system in recirculation for extended periods of
time may cause fogging of the vehicle’s windows.
To clear the fog, select either defog or front
defrost.
You may also notice that the air condition
compressor will run while in recirculation mode.
This is normal and helps to prevent fogging.

Battery Warning Light
If this light comes on
when the engine is
running, there could be
a problem with the
charging system.
The battery display will also stay on while the key
is in RUN until the engine is started.
If the light stays on after starting the engine it
could indicate a problem with the generator drive
belt, or some other charging system problem.
Have it checked right away. Driving while this light
is on could drain the battery.
If you must drive a short distance with this light
on, it helps to turn off all your accessories, such as
the radio and the air conditioner.
Voltmeter Gage
When the engine is not
running, but the ignition
is in RUN, this gage
shows your battery’s
state of charge in
DC volts.
While the engine is running, this gage shows the
condition of the charging system. The gage
may transition from a higher to lower or a lower to
higher reading. This is normal. Readings
between the low and high warning zones indicate
the normal operating range. The voltmeter
gage may also read lower when in fuel economy
mode. This is normal.
Readings in the low warning zone may occur
when a large number of electrical accessories are
operating in the vehicle and the engine is left at
an idle for an extended period.
