Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage your
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell you what to do to help avoid the
damage.
When you read other manuals, you might see CAUTION
and NOTICE warnings in different colors or in different
words.
There are also warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the following
topics:
Seats and Restraint Systems in Section 1
Features and Controls in Section 2
Instrument Panel Overview in Section 3
Climate Controls in Section 3

iv

In many crashes severe enough to inate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.
Air bags are designed to inate only once. After an
air bag inates, you’ll need some new parts for
your air bag system. If you don’t get them, the air
bag system won’t be there to help protect you
in another crash. A new system will include air bag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
Your vehicle is equipped with an electronic frontal
sensor, which helps the sensing system distinguish
between a moderate frontal impact and a more
severe frontal impact. Your vehicle is also equipped
with a crash sensing and diagnostic module,
which records information about the frontal air bag
system. The module system records information
about the readiness of the system, when the system
commands air bag ination and driver’s safety
belt usage at deployment or near-deployment crash.
The module also records speed, engine rpm,
brake and throttle data.
Let only qualied technicians work on your air bag
systems. Improper service can mean that an air
bag system won’t work properly. See your dealer for
service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s air bag, or the air
bag covering on the driver’s, right front passenger’s
or rear seatback, the bag may not work properly.
You may have to replace the air bag module in the
steering wheel, both the air bag module and the
instrument panel for the right front passenger’s air
bag, or both the air bag module and seatback
for the side impact air bag. Do not open or break
the air bag coverings.

Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can not see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-37.
Trunk Lock Release
The trunk lock release
button is located to the left
of the steering wheel on
the instrument panel.
Press the button to open the trunk. To use this feature,
your vehicle must be in PARK (P) or NEUTRAL (N)
and the valet lockout switch must be off.
You can also press the button with the trunk symbol on
the remote keyless entry transmitter to open the
trunk. To disable this feature, see “Valet Lockout Switch”
underTheft-Deterrent Systems on page 2-19.
2-12

PASS-Key®III Operation
Your vehicle is equipped with the PASS-Key®III
(Personalized Automotive Security System)
theft-deterrent system. PASS-Key
®III is a passive
theft-deterrent system. This means you do not have to
do anything different to arm or disarm the system. It
works when you insert or remove your key from
the ignition.
When the PASS-Key
®III system senses that someone
is using the wrong key, it shuts down the vehicle’s
starter and fuel systems. The starter will not work and
fuel will stop being delivered to the engine. Anyone
using a trial-and-error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.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 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 5-108. 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 PASS-Key
®
III to have a new key made.
2-22

It is possible for the PASS-Key®III 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 PASS-Key
®III to
have new keys made. To program additional keys you
will require two current driver’s keys (black in color). 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 the 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 10 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. Your PASS- Key
®III system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS-Key
®III system at this time.
If you lose or damage a PASS-Key
®III key, contact
your dealer to have a new key made.
In an emergency, contact Cadillac Roadside Assistance.
SeeRoadside Service on page 7-6.

A (OFF):This is the only position in which you can
insert or remove the key. This position locks the ignition
and transaxle. 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. If
your vehicle has a column shifter, you will still be able to
move the shift lever. Use ACCESSORY if you must have
your vehicle in motion while the engine is off, for example,
if your vehicle is being pushed or towed.
C (ON):This position is for driving. If your vehicle has a
console shifter and you turn off the engine, the
transaxle will lock. If you need to shift the transaxle out
of PARK (P), the ignition key has to be in ON.
D (START):This position starts the engine.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:
Cellular Telephone
Radio
Power Windows
Audio Steering Wheel Controls
Sunroof
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. If the cellular phone is
being used while retained accessory power is active,
the timer is suspended to avoid interruption of the call.
The timer resets to 10 minutes at the end of the call.
2-25

Starting Your Engine
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:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.
1. With your foot off the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as
your engine gets warm.
Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.2. If it does not start within 10 seconds, hold your key
in START for about 10 seconds at a time until your
engine starts. Wait about 15 seconds between
each try.
3. If your engine still 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 hold the key in
START for about three seconds. If the vehicle starts
briey 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.
