Vehicle Security - Chevrolet silverado 2012 Owner's Manual

Vehicle Security

This vehicle has theft-deterrent
features; however, they do not make
it impossible to steal.
Anti-theft Alarm System
This vehicle may have a content
theft-deterrent alarm system.
This is the security light.
To arm the theft-deterrent system:
1. Open the door.
2. Lock the door with the Remote
Keyless Entry (RKE) transmitter.
The security light should flash.
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 system is armed when the
security light goes off.
If a locked driver door is opened
without using the RKE transmitter, a
10 second pre-alarm will occur. The
horn will chirp and the lights will
flash. If the key is not placed in the
ignition and turned to START or the
door is not unlocked by pressing
the unlock button on the RKE
transmitter during the 10 second
pre-alarm, the alarm will go off. The
vehicle's headlamps will flash and
the horn will sound for about
30 seconds, then will turn off to save
the battery power.
Keys, Doors, and Windows
The theft-deterrent system will not
activate if the doors are locked with
the key or the manual door lock.
It activates only if you use the
power door lock switch or the RKE
transmitter. The vehicle can be
started with the correct key if the
alarm is set off.
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
RKE transmitter.
If the alarm is set off, press unlock
on the RKE transmitter or place the
key in the ignition and turn it to
START.
