To arm the system, do the following:
1. Lock the door using the Remote Keyless
Entry (RKE) transmitter or the power door
lock switch.
2. Close all the doors. The security light
will come on. It should go off within
approximately 30 seconds. Your security
system is now armed.
If a door or a trunk is opened without a key or a
RKE transmitter, the horn will sound and the lamps
will ash for up to 30 seconds.
The theft-deterrent system will not arm if you lock
the doors with a key or use the manual door
lock. It activates only if you use the RKE
transmitter or the power lock on the door.To avoid activating the alarm by accident do the
following:
Lock the door with the key or the manual door
lock after the doors are closed if you do not
want to arm the theft-deterrent system.
Always unlock a door with a key or use the
RKE transmitter. Pressing the unlock button
on the RKE transmitter disables the
theft-deterrent system.
Unlocking a door any other way will activate
the alarm when a door or the trunk is opened.
If you activate the alarm by accident, unlock the
driver’s door with your key. You can also turn
off the alarm by using the unlock button on the
RKE transmitter, or by starting the vehicle with a
valid key.

Testing the Alarm
1. Roll down the window, then get out of the
vehicle, keeping the door open.
2. From outside of the vehicle, with the door
open, lock the vehicle using the power door
lock switch or the RKE transmitter and close
the door. Wait approximately 30 seconds
until the security light goes off.
3. Reach in and unlock the door using the
manual lock and open the door. The horn
will sound and the exterior lamps will ash.
The alarm can be turned off by unlocking the
driver’s door with the key, using the unlock button
on the RKE transmitter or by starting the car
with a valid key.
If the alarm does not sound when it should, check
to see if the horn works. The horn fuse may be
blown. To replace the fuse, seeFuses and Circuit
Breakers on page 447. If the fuse does not need
to be replaced, you may need to have your vehicle
serviced.
To reduce the possibility of theft, always arm the
theft-deterrent system when leaving your vehicle.

Immobilizer Operation
Your vehicle has a
passive theft-deterrent
system.
The system works when the key is turned to ON.
The key uses a transponder that matches an
immobilizer control unit in your vehicle. 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, the
key may have a damaged transponder. 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 447. 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 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 additional keys may be
programmed for the vehicle. The following
procedure is for programming additional keys only.
114
Page 115 of 518

Canadian Owners:If you lose or damage your
keys, only a GM dealer can service the
theft-deterrent system to have new keys made.
To program additional keys you will require
two current driver’s keys. You must add a step to
the following procedure. After Step 2, repeat
Steps 1 and 2 with the second current driver’s key.
Then continue with Step 3.
To program a new key do the following:
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 will not
start see your dealer for service.
3. After the engine has started, turn the key to
OFF, and remove the key.4. Insert the key to be programmed and turn it to
ON within ten seconds of removing the
previous key.
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.
If the security light comes on and stays on while
driving, you will be able to restart the engine if you
turn it off. The theft-deterrent system, however,
is not working properly and must be serviced
by your dealer. Your vehicle is not protected by
the theft-deterrent system at this time.
In an emergency, contact Cadillac Roadside

Ignition Positions
With the key in the ignition switch, you can turn
the key to four different positions.
Notice:Using a tool to force the key from its
cylinder could cause damage or break the key.
Use the correct key and turn the key only with
your hand. Make sure the key is all the way in.
If it is and you have a manual transmission
vehicle, turn the steering wheel left and right
while you turn the key hard. If none of this
works, then your vehicle needs service.A (OFF):This is the only position in which the
key can be inserted or removed. This position
locks the ignition and shifter on automatic
transmission vehicles, and the ignition and steering
wheel on manual transmission vehicles.
B (ACCESSORY):This position allows you to use
things like the radio and the windshield wipers
when the engine is off. This position will allow you
to turn off the engine.
C (ON):This position is for driving. If your vehicle
has an automatic transmission and you turn off
the engine, the transmission will lock. If you need
to shift the transmission out of PARK (P), the
ignition key has to be in ACCESSORY or ON.
The battery could be drained if you leave the key
in the ACCESSORY or ON position with the
engine off. You may not be able to start your
vehicle if the battery is allowed to drain for
an extended period of time.
D (START):This position starts the engine.

Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your vehicle,
a chime will sound, when you open the driver’s
door. Always remember to remove the key
from the ignition and take it with you. This will lock
the ignition and transmission. Also, always
remember to lock the doors.
The battery could be drained if you leave the
key in the ignition while your vehicle is parked.
You may not be able to start your vehicle
after it has been parked for an extended period
of time.
Key Release Button
(Manual Transmission)
The key cannot be
removed from the
ignition of a manual
transmission vehicle,
unless the key release
button is used.
To remove the key, do the following:
1. Turn the key to ACCESSORY.
2. Press and release the button and then turn
the key to OFF.
Do not hold the button in while turning the key
to OFF.
3. Pull the key straight out of the ignition switch.

Retained Accessory Power (RAP)
The following accessories on your vehicle may be
used for up to 10 minutes after the ignition key
is turned from ON to OFF:
Radio
Power Windows
Audio Steering Wheel Controls
Sunroof
Power to these accessories stops after 10 minutes
or if a door is opened. If an additional 10 minutes
of power is needed, close all the doors and
turn the ignition key to ON and then back to OFF.
Starting the Engine
Automatic Transmission
Move your shift lever to PARK (P) or
NEUTRAL (N). Your engine will not start in
any other position — that is a safety feature.
To restart when you are already moving,
use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could
damage the transmission. Shift to PARK (P)
only when your vehicle is stopped.
Manual Transmission
The shift lever should be in NEUTRAL and the
parking brake engaged. Hold the clutch pedal
to the oor and start the engine. Your vehicle
will not start if the clutch pedal is not all the way
down — that is a safety feature.
1. With your foot off the accelerator pedal, turn
your ignition key to START. Then, let go of
the key; the engine will start automatically.
The idle speed will go down as your engine
gets warm. Do not race the engine
immediately after starting it. Operate the
engine and transmission gently until the oil
warms up and lubricates all moving parts.
Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects the electrical
system. If the ignition key is turned to the
START position, and then released when the
engine begins cranking, the engine will
continue cranking until the vehicle starts or
until it exceeds the maximum cranking
time allowed, approximately 15 seconds
to prevent cranking motor damage.
119
Page 120 of 518

To prevent starter-motor gear damage, this
system also prevents cranking if the engine is
already running. The engine cranking can
be stopped by turning the ignition switch to the
ACCESSORY or OFF position.
2. If your engine will not start, or starts but then
stops, it could be ooded with too much
gasoline. Try pushing your accelerator pedal
all the way to the oor and holding it there
as you turn the key to START. If the vehicle
starts brie y but then stops again, do the
same thing.
Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with
your dealer. If you do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.Engine Coolant Heater
Your vehicle may have an engine coolant heater.
In very cold weather, 0°F (−18°C) or colder,
the engine coolant heater can help. You will get
easier starting and better fuel economy during
engine warm-up.
Usually, the coolant heater should be plugged in
a minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C), use of
the coolant heater is not required. Your vehicle
may also have an internal thermostat in the
plug end of the cord. This will prevent operation of
the engine coolant heater when the temperature
is at or above 0°F (−18°C) as noted on the cord.
