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.
2-29

Ignition Positions (Key Access)
The key can be turned to four different positions.
To shift out of P (Park), the ignition must be in the
ON/RUN or ACC/ACCESSORY and the brake pedal
must be applied.
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 the vehicle needs service.A (LOCK/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 (ACC/ACCESSORY):This position lets you use
things like the radio and the windshield wipers when
the engine is off. This position allows you to turn off
the engine.
C (ON/RUN):This position is for driving. It is the
position the ignition switch returns to after the engine
starts, and the key is released.
To shift the transmission out of P (Park), the ignition
key has to be in ACC/ACCESSORY or ON/RUN.
The battery could be drained if the key is left in the
ACC/ACCESSORY or ON/RUN position with the
engine off. The vehicle might not start if the battery
is allowed to drain for an extended period of time.
D (START):This position starts the engine. When
the engine starts, release the key. The ignition switch
returns to ON/RUN for driving.
A warning tone will sound when the driver door is
opened, the ignition is in ACC/ACCESSORY or
LOCK/OFF and the key is in the ignition.
2-31

If the ignition is on, the brake system warning light on the
instrument panel cluster should come on. If it does not,
you need to have the vehicle serviced. SeeBrake System
Warning Light on page 3-39for more information.
To release the parking brake, pull the release lever
located to the left of the steering wheel on the instrument
panel.Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the brake
warning light is off before driving.
A warning chime will sound if the parking brake is set,
the ignition is on, and the vehicle begins to move.
To stop the chime, fully release the parking brake.

EPB Apply
The EPB can be applied any time the vehicle is stopped.
The EPB is applied by momentarily lifting up on the EPB
switch. Once fully applied, the BRAKE light will be on,
and the DIC message “Park Brake Set” will be displayed.
If the light does not come on, or is ashing, you need to
have the vehicle serviced. Do not drive the vehicle if
the BRAKE light is ashing. See your dealer/retailer.
SeeBrake System Warning Light on page 3-39for more
information.
If the EPB is applied while the vehicle is in motion,
a chime will sound, and the DIC message “Release
Park Brake Switch” will be displayed. The vehicle
will decelerate as long as the switch is held in the
up position. Releasing the EPB switch during the
deceleration will release the parking brake. If the
switch is held in the up position until the vehicle
comes to a stop, the EPB will remain applied.
If the BRAKE light is on, either the EPB is applied, or
there is a failure in the hydraulic brake system.If this light is ashing, the EPB is only partially applied
or released, or there is a problem with the EPB.
The DIC message “Service Park Brake” will be
displayed. If this light is ashing, release the EPB, and
attempt to apply it again. If this light continues to
ash, do not drive the vehicle. See your dealer/retailer.
If the
Ylight is on, the EPB has detected an error
in another system and is operating with reduced
functionality. To apply the EPB when this light is on, lift up
on the EPB switch and hold it in the up position. Full
application of the parking brake by the EPB system may
take a longer period of time than normal when this light is
on. Continue to hold the switch until the BRAKE light
remains on. If the
Ylight is on, see your dealer/retailer.
If the EPB fails to apply, the rear wheels should be
blocked to prevent vehicle movement.
