2007 Chevrolet Silverado 1500 Pickup Owner's Manual - Page 131

This message reminds you to activate the theft-deterrent system. Here is how to do it: 1. Open the door. 2. Lock the door with the Remote Keyless Entry (RKE) transmitter. The security light should come on and flash. The door does not need to be open. If the delayed locking feature is active, the alarm will not be activated until all doors are closed and the security light goes off. 3. Close all doors. The security light will stop flashing and go off after approximately 30 seconds. The content theft deterrent alarm is not armed until the security light goes off. If a door is opened without using the RKE transmitter, the alarm will go off. Your vehicle's headlamps will flash and the horn will sound for about two minutes, then will turn off to save the battery power. The theft-deterrent system will not activate if you lock the doors with a key, the manual door lock, or the power door lock switch. It activates only if you use the RKE transmitter. You should also remember that you can start your vehicle with the correct ignition key if the alarm has been set off. Here is how to avoid setting off the alarm by accident: • 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 remote keyless entry transmitter. Unlocking a door any other way will set off the alarm if the system has been armed. If you set off the alarm by accident, turn off the alarm by pressing unlock on the remote keyless entry transmitter or by placing the key in the ignition and turning it to START. 131
