Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver’s window
and open the driver’s door.
2. Activate the system by locking the doors with the
transmitter.
3. Get out of the vehicle, close the door and wait for
the security light to go out.
4. Then reach in through the window, unlock the
door with the manual door lock and open the door.
This should set off the alarm.
While the alarm is set, the power door unlock switch will
not work.
If the alarm does not sound when it should but the
headlamps ash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
seeFuses and Circuit Breakers on page 5-115Fuses
and Circuit Breakers.
If the alarm does not sound or the headlamps do not
ash, the vehicle should be serviced by your
dealer/retailer.

2-27

Immobilizer Operation (Key Access)
Your vehicle has a passive theft-deterrent system.
The system is automatically armed when the key
is removed from the ignition.
The theft-deterrent system is disarmed when the key is
turned to ON/RUN.
You do not have to manually arm or disarm the system.
The security light will come 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 your vehicle and automatically disarms the
system. Only the correct key will start the vehicle. If the
key is ever damaged, you may not be able to start your
vehicle.
When trying to start the vehicle, if the engine does not
start and the security light comes on, there may be a
problem with your 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. At this time, you
may also want to check the fuse. SeeFuses and Circuit
Breakers on page 5-115. If the engine still does not start
with the other key, your vehicle needs service. If your
vehicle does start, the rst key may be faulty. See your
dealer/retailer 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.
To program a new key do the following:
1. Verify that the new key has
1stamped on it.
2. Insert the current driver’s key in the ignition and
start the engine. If the engine will not start see
your dealer/retailer for service.
3. After the engine has started, turn the key to
LOCK/OFF, and remove the key.
4. Insert the key to be programmed and turn it to
ON/RUN within ve seconds of the ignition being
turned to LOCK/OFF in Step 3.
5. The security light will turn off once the key has
been programmed. It may not be apparent that
the security light went on due to how quickly the key
is programmed.
6. Repeat the Steps 1 through 4 if additional keys are
to be programmed.
In an emergency, contact Cadillac Roadside Service.
SeeRoadside Service on page 7-7.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

Immobilizer Operation
(Keyless Access)
Your vehicle has a passive theft-deterrent system.
The system is automatically armed when the ignition
control knob is turned to LOCK/OFF.
The immobilization system is disarmed when the ignition
control knob is pushed in and a valid transmitter is
found in the vehicle.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
The system has one or more keyless access transmitters
that are matched to an immobilizer control unit in your
vehicle. Only a correctly matched keyless access
transmitter will start the vehicle. If the keyless access
transmitter is ever damaged, you may not be able to
start your vehicle.
When trying to start the vehicle, if the engine does not
start and the security light comes on, there may be a
problem with your immobilizer system. Turn the ignition
control knob off and try again.If the ignition control knob does not rotate, and the
keyless access transmitter appears to be undamaged,
try another keyless access transmitter. Or, you may
try placing the transmitter in the transmitter pocket
located in the center console. See “Electronic Key Not
Detected” underDIC Warnings and Messages on
page 3-58. At this time, you may also want to check the
fuse. SeeFuses and Circuit Breakers on page 5-115.
If the ignition control knob still does not rotate with
the other transmitter, your vehicle needs service. If the
ignition control knob does rotate, the rst transmitter
may be faulty. See your dealer/retailer who can service
the theft-deterrent system and have a new keyless
access transmitter programmed to the vehicle.
It is possible for the immobilizer system to learn new or
replacement keyless access transmitters. Up to 4 keyless
access transmitters can be programmed for the vehicle.
To program additional transmitters, see “Matching
transmitter(s) to Your Vehicle” underKeyless Access
System Operation on page 2-8.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

Monitor System (TPMS) is not working properly. The tire
pressure light also ashes and then remains on during
the same ignition cycle. SeeTire Pressure Light on
page 3-42. Several conditions may cause this message
