2-12 Features and Controls Testing the Alarm To test the alarm: 1. From inside the vehicle, lock the doors with the RKE transmitter. 2. Unlock the door with the manual door lock and open the door. The pre-alarm should sound followed by the full alarm about 10 seconds later. 3. Press the unlock button on the RKE transmitter or start the engine to turn the alarm off. If the alarm does not sound but the lights flash, check to see if the horn works. The horn fuse could be blown. To replace the fuse, see Fuses and Circuit Breakers on page 5-91. If the alarm does not sound or the front turn signal lamps do not flash, see your dealer/retailer for service. To avoid setting off the alarm by accident: Passlock® (U.S. Only) Passlock® is a passive theft-deterrent system that enables fuel if the vehicle is started 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 does not start. The security light turns off approximately five seconds after the engine is started. See Security Light on page 3-33. If the engine stalls and the security light flashes, wait about 10 minutes until the light stops flashing before trying to restart the engine. Release the key from START as soon as the engine starts. If the engine does not start after three tries, the vehicle needs service. • Lock the vehicle with the manual door lock lever, the power door lock switch, or the key, after the doors are closed. • Unlock the doors by pressing the unlock button on the RKE transmitter or by contacting OnStar. Unlocking a door any other way activates the alarm. Press unlock on the RKE transmitter, start the vehicle with the correct key, or have OnStar unlock the doors to turn the alarm off. The alarm does not stop if a door is unlocked any other way.
