Immobilizer Operation
Your vehicle is equipped
with a passive
theft-deterrent system.
The system works when you turn the key to ON. 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. SeeFuses
and Circuit Breakers on page 5-100. 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 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.
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.
2-20
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.

New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
“break-in.” But it will perform better in the long
run if you follow these guidelines for the rst
500 miles (805 km):
Do not drive at any one speed — fast or slow.
Do not exceed 70 mph (113 km/h).
Do not 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 rst 200 miles
(322 km) or so. During this time your new brake
linings are not yet broken in. Hard stops with new
linings can mean premature wear and earlier
replacement. Follow this break-in guideline every
time you get new linings.
Do not tow a trailer during break-in. SeeTowing a
Trailer on page 4-39for more information.

Ignition Positions
With the key in the ignition switch, you can turn the key
to four different positions.
Notice:If your key seems stuck in OFF and you
can’t turn it, be sure you are using the correct key;
if so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the key
hard. Turn the key only with your hand. Using a
tool to force it could break the key or the ignition
switch. If none of these works, then your vehicle
needs service.A (OFF):This is the only position in which you can
insert or remove the key. This position locks the
ignition, steering wheel and transmission. It’s a
theft-deterrent feature.
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, but still turn the steering wheel.
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 ON.
D (START):This position starts the engine.

Key Release Button
(Manual Transmission)
The key cannot be
removed from the ignition
of 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 the button and 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.
Steering Column Ignition Lock Release
(Automatic Transmission)
If your vehicle has a dead battery or a battery with low
voltage, you can still release the ignition lock and
remove the key. Use the following procedure to release
the steering column:
1. Locate the plastic screw head on the underside of
the plastic cover for the steering column.
2. Insert a at, thin object into the slot and turn it
until the plastic piece detaches from the steering
column cover.

3. Insert a narrow, pointed object into the hole in the
steering column cover and press the spring.
4. Then, turn the ignition switch to OFF and remove
the key.
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 (if programmed)
Sunroof (Option)
Power to these accessories stops after 10 minutes or if
a door is opened. If you want power for another
10 minutes, close all the doors and turn the ignition key
to ON and then back to OFF.
Starting Your 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.
