Read the instructions completely before attempting
to program the transmitter. Because of the steps
involved, it may be helpful to have another
person available to assist you in programming
the transmitter.
Be sure to keep the original remote control
transmitter for use in other vehicles, as well as,
for future programming. You only need the
original remote control transmitter for Fixed Code
programming. It is also recommended that
upon the sale or lease termination of the vehicle,
the programmed buttons should be erased for
security purposes. See "Erasing Universal
Home Remote Buttons" later in this section.
When programming a garage door, it is advised
to park outside of the garage. Be sure that
people and objects are clear of the garage door
or security device you are programming.
