This vehicle has theft-deterrent
features; however, they do not make
it impossible to steal.
Anti-theft Alarm System
If your vehicle has the Remote
Keyless Entry (RKE) system, the
vehicle has a content theft-deterrent
alarm system.
To activate the content
theft-deterrent system:
1. Close all the doors.
2. Lock the doors with the RKE transmitter. The security light,
located on the instrument panel
cluster, will flash. If the LOCK button on the RKE
transmitter is pressed, but a door is
open, the horn will chirp six times.
Press the LOCK button again, within
three seconds, and the doors will
lock. Close the open door and the
system will be activated.
If a locked door is not opened using
the RKE transmitter, or by OnStar
®,
the pre-alarm will go off. If the
engine is not started or UNLOCK
not pressed within 10 seconds, the
front turn signal lamps will flash for
two minutes, and the horn will sound
for two minutes, then will turn off to
save the battery power.
Remember, the theft-deterrent
system will not activate if you lock
the doors with a key, the manual
door lock, or power door lock
switch. The system can only be
activated using the RKE transmitter,
or by OnStar
®. See the OnStar
Owner's Guide for additional
information. You should also
remember that you can start your
vehicle with the correct ignition key
if the alarm has been set off.

2-10 Keys, Doors, and Windows
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
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 10‑39.
If the alarm does not sound or the
front turn signal lamps do not flash,
see your dealer for service.

theft-deterrent system.
The system is automatically armed
when the key is removed from the
ignition.
The system is automatically
disarmed when the key is turned
to ON/RUN.
You do not have to manually arm
or disarm the system.
The security light comes on if
there is a problem with arming or
disarming the theft-deterrent
system.
The key uses a transponder that
matches an immobilizer control unit
in the vehicle. Only the correct key

damaged, the vehicle may not start.
When trying to start the vehicle,
if the engine does not start and
the security light comes on, there

Keys, Doors, and Windows 2-11
may be a problem with the
theft-deterrent system. Turn the
ignition off and try again.
If the engine still does not start, and
the key appears to be undamaged,
try another ignition key. Check
the fuse. SeeFuses and Circuit
Breakers on page 10‑39. If the
engine still does not start with the
other key, the vehicle needs service.
If the vehicle does start, the first key
may be faulty. See your dealer who
can service the theft-deterrent
system and have a new key made.
It is possible for the theft-deterrent
system decoder to learn the
transponder value of a new or
replacement key. Up to 10 keys
can be programmed for the vehicle.
The following procedure is for
programming additional keys only.
Canadian Owners: If the keys are
lost or damaged, only a dealer can
service the theft-deterrent system to
have new ones made. Two current
driver's keys are required to
program additional keys. To program a new key:
1. Verify that the new key has
PK3+ stamped on it.
2. Insert the current driver's key in the ignition and start the engine.
If the engine does not start see
your dealer for service.
3. After the engine has started, turn the key to LOCK/OFF, and
remove the key.
4. Insert the second current driver's key in the ignition and start the
engine within ten seconds of
removing the previous key. If the
engine does not start see your
dealer for service.
5. After the engine has started, turn the key to LOCK/OFF, and
remove the key. Insert the key
to be programmed and turn it to
ON/RUN within ten seconds of
removing the previous key.
The security light turns off once
the key has been programmed. 6. Repeat Steps 1 through 5 if
additional keys are to be
programmed.
If the security light comes on and
stays on while driving, the engine
will restart if you turn it off. However,
the theft-deterrent system is not
working properly and must be
serviced by your dealer. The
vehicle is not protected by the
theft-deterrent system at this time.
In an emergency, contact Roadside
Assistance. See Roadside
Assistance Program (U.S. and
Canada) on page 13‑7 orRoadside

A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the right lane,
you could hit a vehicle on the
