Here is how to avoid setting off the alarm by accident: Passlock® (U. S. Only) Your vehicle has 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 an incorrect key is used or the ignition lock cylinder is tampered with, the fuel system is disabled and the vehicle will not start. During normal operation, the security light will turn off approximately five seconds after the engine is started. See Security Light on page 3-37. If the engine stalls and the security light flashes, wait about 10 minutes 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 does not start after three tries, the vehicle needs service. 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/retailer. Your vehicle is not protected by Passlock® at this time. See your dealer/retailer for service. In an emergency, call the Roadside Assistance Center. See Roadside Assistance Program on page 7-7. Do not leave the key or device that disarms or deactivates the theft deterrent system in the vehicle. • If you do not want to activate the theft-deterrent system, the vehicle should be locked with the door key after the doors are closed. • Always unlock a door with the RKE transmitter. Unlocking a door any other way will set off the alarm. If you set off the alarm by accident, you can turn off the alarm by pressing unlock on the RKE transmitter. The alarm will not stop if you try to unlock a door any other way. Testing the Alarm To test the alarm: 1. From inside the vehicle, activate the system by locking the doors with the RKE transmitter. 2. Unlock the door with the manual door lock and open the door. This should set off the alarm. 3. To turn the alarm off, press the unlock button on the RKE transmitter or start the engine. If the alarm does not sound when it should but the lights flash, check to see if the horn works. The horn fuse may be blown. To replace the fuse, see Fuses and Circuit Breakers on page 5-116. If the alarm does not sound or the front turn signal lamps do not flash, see your dealer/retailer for service. 2-16
