Programming Transmitters to
the Vehicle
Only RKE transmitters
programmed to this vehicle will
work. If a transmitter is lost or
stolen, a replacement can be
purchased and programmed through
your dealer. When the replacement
transmitter is programmed to this
vehicle, all remaining transmitters
must also be reprogrammed.
Any lost or stolen transmitters
will no longer work once the new
transmitter is programmed. Each
vehicle can have up to four
transmitters programmed to it.
Battery Replacement
The battery in the transmitter is
weak and should be changed if it
does not work at the normal range
in any location.
Notice:When replacing the
battery, do not touch any of the
circuitry on the transmitter. Static
from your body could damage the
transmitter. To replace the battery:
1. Separate the transmitter with a
flat, thin object inserted into the
notch on the side.
2. Remove the old battery. Do not use a metal object.
3. Insert the new battery. Replace with a CR2032 or equivalent
battery.
4. Snap the transmitter back together.

Vehicle Security
Vehicle theft is big business,
especially in some cities. This
vehicle has theft-deterrent features,
however, they do not make it
impossible to steal.
Anti-Theft Alarm System
This vehicle has a content
theft-deterrent alarm system.
The security light is located on the
instrument panel cluster.
To arm the system:
1. Close all the doors.
2. Lock the doors with the RemoteKeyless Entry (RKE) transmitter.
The security light flashes. If the lock button on the RKE
transmitter is pressed, but a door is
open, the doors lock, the lights may
flash and the horn may sound.
Close the open door to arm the
system.
The alarm goes off if a locked door
is not opened using the RKE
transmitter, or by OnStar
®.
A pre-alarm sounds the horn at
reduced intensity for 10 seconds.
Then, the front turn signal lamps
flash for two minutes, and the horn
sounds for two minutes. The alarm
then turns off to save battery power.
Start the engine to turn off the
alarm.
The theft-deterrent system does
not activate if the doors are locked
with the 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. The vehicle
can be started with the correct key if
the alarm has been set off.

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

Immobilizer Operation
(Canada)
This vehicle has a passive
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
starts the vehicle. If the key is ever
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 may
be a problem with the theft-deterrent
system. Turn the ignition off and try
again.

2-12 Keys, Doors and Windows
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.
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 the 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 Service
on page 13‑5.
Do not leave the key or device that
disarms or deactivates the theft
deterrent system in the vehicle.
