It is necessary to haveall(maximum of four—original and/or new) of
your remote transmitters available prior to beginning this procedure.
To program the transmitters yourself:
•Insert a key in the ignition and
turn from 1 (LOCK) to 3 (ON)
and cycle between 1 (LOCK) and
3 (ON) eight times in rapid
succession (within 10 seconds)
with the eighth turn ending in the
3 (ON) position. The doors will
lock/unlock to confirm that
programming mode has been
entered.
•Within 20 seconds, program a remote transmitter by pressing any
button on a transmitter. The doors will lock/unlock to confirm that the
remote transmitter has been programmed. (If more than 20 seconds
pass before pressing a remote transmitter button, the programming
mode will exit and the procedure will have to be repeated.)
•Repeat the previous step to program additional remote transmitters.
The doors will lock/unlock to confirm that each remote transmitter has
been programmed.
•When you have completed programming the remote transmitters, turn
the ignition to 1 (LOCK) or wait 20 seconds. Again the doors will
lock/unlock to confirm programming has been completed.

system to operate.
The inside lights will not turn off if:
