How to Turn Off the System Alarm If the system alarm is active, it can be deactivated by: 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. During normal operation, the THEFT SYSTEM light will go off approximately five seconds after the key is turned to the RUN ignition position following an engine start. If the engine stalls and the THEFT SYSTEM 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 THEFT SYSTEM 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 5-81. • Pressing the LOCK or panic button on the transmitter to turn off the alarm. The system will re-arm if all doors and the trunk are later closed. • Pressing the UNLOCK or trunk button on the transmitter to turn off the alarm and disarm the system. • Putting the key in the ignition and turning it to START to turn off the alarm and disarm the system. How to Detect a Tamper Condition If you hear three horn chirps when you press the UNLOCK, LOCK or trunk buttons on your transmitter, the content theft security system alarm was triggered while you were away. Your dealer can change the settings to disable the headlamp flash and horn chirp features. Your dealer can also change the settings to allow the horn to chirp twice on the first press of the UNLOCK button. See your dealer for more information. 2-15
