Automatic Door Locks
If your vehicle has an automatic transmission, your
vehicle is programmed so that when the doors are
closed, the ignition is on and the shift lever is moved out
of PARK (P), all the doors will lock. The doors will
unlock every time you stop the vehicle and move the
shift lever back into PARK (P).
If your vehicle has a manual transmission, the doors
will lock automatically after the vehicle speed reaches
5 mph (8 km). The doors will not automatically unlock
until the ignition is turned off and the key is removed
from the ignition switch.
If someone needs to exit the vehicle once the doors have
locked, have that person use the manual lever or power
door lock switch. When the door is closed again, it will
not lock automatically. Use the manual lever or power
lock switch to lock the door.
Programmable Automatic Door Locks
The power door locks can be programmed through
prompts displayed on the Driver Information Center
(DIC). These prompts allow you to choose various
lock and unlock settings. For more information on
programming, see ªVehicle Programming and
Personalization Featuresº in the Index.
Rear-Door Security Locks
Your vehicle is equipped with rear door security locks
that prevent passengers from opening the rear doors on
your vehicle from the inside.
The rear door security locks
are located on the inside
edge of each rear door. You
must open the rear doors to
access them.
To use these locks, do the following:
1. Insert your key into the slot next to the rear door
security lock label and turn it to engage the lock.
2. Close the door.
3. Repeat the steps for the other rear door.
The rear doors on your vehicle cannot be opened from
the inside when this feature is in use.

When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door using the remote keyless entry
transmitter, the front door power lock switch or by
lifting the rear door manual lock.
2. Then open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
2. Insert your key into the slot next to the rear door
security lock label and turn it to disengage the lock.
3. Repeat the steps for the other lock.
The rear door locks will now work normally.
Anti-Lockout Feature
The power door lock switches will not work if the key is
in the ignition, the engine is off, a door is open and
delayed locking is turned off. If you press the power
door lock switch, all the doors will lock and only the
driver's door will unlock. If you close the doors, you can
lock them using the remote keyless entry transmitter. Be
sure to remove the key from the ignition when locking
your vehicle.
The anti
-lockout feature can be overridden by pressing
the lock button on the remote keyless entry transmitter.
Leaving Your Vehicle
If you are leaving your vehicle, open the door, lock the
vehicle from the inside; then get out and close the door.
Remote Keyless Entry System
With this feature, you can lock and unlock the doors or
the trunk and turn on your vehicle's interior lamps from
about 10 feet (3 m) away using the remote keyless entry
transmitter supplied with your vehicle.
Your remote keyless entry system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.

(Unlock): When you press this symbol on the
remote keyless entry transmitter, the driver's door will
unlock. This also disarms the theft
-deterrent system.
Press the button again to unlock the rest of the doors.
You can program your vehicle so that the exterior lamps
will flash when you unlock the doors with the remote
keyless entry transmitter. See ªVehicle Programming
and Personalization Featuresº in the Index for more
information on programming this feature.
If your vehicle is programmed for remote confirmation,

Matching Transmitter(s) to Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have a maximum of four
transmitters matched to it.

Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft
-deterrent
features, we know that nothing we put on it can make
it impossible to steal. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition and transmission. And remember to lock
the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
Even if you park in a lot where someone will be
watching your vehicle, it's still best to lock it up and
take your keys. But what if you have to leave your key?

If possible, park in a busy, well
-lit area.

Put your valuables in a storage area, like your trunk
or glove box.

Be sure to close and lock the storage area.

Close all windows.

Lock the glove box.

Theft-Deterrent System
The security light is located
on the instrument panel
cluster.
If the ignition is off and a door is open, the security light
will flash, reminding you to arm the theft
-deterrent
system.
To arm the system, do the following:
1. Open the door.
2. Lock the door using the remote keyless entry
transmitter or the power door lock switch. The
security light should come on and stay on.
3. Close all the doors. The security light should go off
within approximately 30 seconds.
If a door or a trunk is opened without a key or a remote
keyless entry transmitter, the horn will sound and the
lamps will flash for up to 30 seconds.The theft
-deterrent system won't arm if you lock the
doors with a key or use the manual door lock. It
activates only if you use the remote keyless entry
transmitter.
To avoid activating the alarm by accident do the
following:

The vehicle should be locked with the door key or
the manual door lock after the doors are closed if
you don't want to arm the theft
-deterrent system.

Always unlock a door with a key or use the remote
keyless entry transmitter. Pressing the unlock button
on the remote keyless entry 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 remote keyless entry
transmitter, or by starting the vehicle with a valid key.

This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this
device must accept any interference received, including
interference that may cause undesired operation of
the device.
Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
The system works when you turn the key to ON (II).
The key uses a transponder that matches an immobilizer
control unit in your vehicle. The correct key will start
the vehicle.
Your vehicle has a special key that works with the
theft
-deterrent system. There is a transponder in the key
head. 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. See ªFuses and
Circuit Breakersº in the Index. If the engine still does
not start with the other key, your vehicle needs service.
If your vehicle does start, the first key may be faulty.
See your dealer who can service the theft
-deterrent
system to 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. This procedure is for learning additional
keys only.

2-23
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 you are ever driving and the security light comes on
and stays on, you will be able to restart your 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 Assistance.
See ªRoadside Assistanceº in the Index.

New Vehicle ªBreak-Inº
NOTICE:
Your vehicle doesn't need an elaborate
ªbreak
-in.º But it will perform better in the
long run if you follow these guidelines for the
first 500 miles (805 km):

Don't drive at any one speed -- fast or slow.

Do not exceed 70 mph (113 km/h).

Don't make full
-throttle starts, also refrain
from using the full throttle while driving.
If these procedures are not followed your engine,
axle or other parts could be damaged.

Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren't yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking
-in guideline every
time you get new brake linings.
Don't tow a trailer during break-in. See ªTowing
a Trailerº in the Index for more information.
Ignition Positions
With the key in the ignition switch, you can turn the key
to four different positions.
