20 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE ON/RUN position. If not deactivated through the transmitter or the ignition switch, the alarm will turn off automatically after 3 minutes. Programming Additional Transmitters NOTE: You must have at least one programmed transmitter to perform this procedure. If you do not have a programmed transmitter, contact your dealer for details. Use this procedure to program up to three additional transmitters for your vehicle. To activate the programming feature, proceed as follows: 1. Turn the ignition switch to the ON/RUN position. 2. Set the parking brake. 3. Press and hold the UNLOCK button for at least 5 seconds, but no longer then 10 seconds on a previously programmed transmitter. Then, press the PANIC button while still holing the UNLOCK button. 4. Release both buttons at the same time. A chime will sound to signal that the programming feature is activated. 5. Within 30 seconds, press and release the LOCK button and the UNLOCK button at the same time on the new transmitter. 6. Press and release any button one time on the new transmitter. A chime will sound to indicate that the new transmitter is programmed. An additional chime will sound at the end of the 30-second programming period. It will also sound if the ignition is switched OFF. 7. Repeat Steps 3 through 6 to program each additional transmitter.
