greater than 8 mph (13 km/h). This is the mode
that is pre-programmed in the factory for manual
transmission vehicles.

programming options listed above before entering
the program mode. To enter the program mode,
do the following:

mode. If this occurs, you can repeat the
procedure beginning with Step 1 to re-enter
the programming mode.

two seconds and then turns to a constant light,
continue with Steps 6 through 8 following to
complete the programming of a rolling-code
device, most commonly, a garage door opener.6. Locate in the garage, the garage door opener
receiver (motor-head unit). Locate the “Learn”
or “Smart” button. This can usually be

“Smart” button. The name and color of
the button may vary by manufacturer.

button for two seconds, then release. Repeat
the press/hold/release sequence a second
time, and depending on the brand of the
garage door opener or other rolling code
device, repeat this sequence a third time to
complete the programming.
The Universal Home Remote should now
activate the rolling-code device.
To program the remaining two Universal
Home Remote buttons, begin with Step 2 of
“Programming Universal Home Remote.” Do not
repeat Step 1, as this will erase all previous
programming from the Universal Home Remote
buttons.

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.
