To avoid setting off the alarm by
accident:
• 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.
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.
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.
