Simulated Armed Mode If you choose not to arm the system or if proper arming cannot be completed, the Content Theft Deterrent system will flash the security light once every three seconds after a one minute delay with all the doors closed. This flashing serves as a visual deterrent; however, the system is not armed. During normal operation, the security light will go off approximately three seconds after the key is turned to RUN following an engine start. The security light is located on the instrument panel cluster. See Instrument Panel Cluster on page 3-22. If the engine stalls and the security light flashes, wait until the light stops flashing before trying to restart the engine. Remember to release the key from START as soon as the engine starts. If the engine is running and the security light comes on, you will be able to restart the engine if you turn the engine off. However, your Passlock® system is not working properly and must be serviced by your dealer. Your vehicle is not protected by Passlock® at this time. See your dealer for service. Or see Roadside Assistance Program on page 7-6 for more information. You may also want to check the fuses. See Fuses and Circuit Breakers on page 5-91. How to Detect a Tamper Condition If you hear three chirps when you press the unlock, lock, or trunk release buttons on the remote keyless transmitter, it means that the content theft security system alarm was activated previously. Passive Arming If passive arming is enabled through the DIC, the system will arm itself 60 seconds after cycling the ignition off and closing all doors. Passlock® Your vehicle is equipped with the Passlock® theft-deterrent system. Passlock® is a passive theft-deterrent system. Passlock® enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder is tampered with, fuel is disabled. 2-15
