Vehicle Damage Warnings
Also, in this book you will find these notices:
NOTICE:
These mean there is something that could damage
your vehicle.
In the notice area, we tell you about something that can
damage your vehicle. Many times, this damage would
not be covered by your 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.
You'll also see warning labels on your vehicle.
They use the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle may be equipped with components and
labels that use symbols instead of text. Symbols,
used on your vehicle, are shown along with the text
describing the operation or information relating to a
specific component, control, message, gage or indicator.
If you need help figuring out a specific name of a
component, gage or indicator reference the following
topics in the Index:

ªEngine Compartment Overviewº

ªInstrument Panelº

ªComfort Controlsº

ªAudio Systemsº

1-3 Memory Seat and Mirrors (If Equipped)
This feature allows you to program and recall memory
settings for the driver's seating and outside rearview
mirror driving positions for up to two drivers.
The buttons for this feature
are located on the driver's
door armrest.
Use the following steps to program the buttons:
1. Adjust the driver's seat including the seatback
recliner and both outside mirrors.
2. Press and hold button 1 for at least three seconds.
Two beeps will sound to confirm that the seat and
mirror positions have been saved.
3. Repeat the procedure for a second driver
using button 2.If your vehicle has an automatic transmission, the
vehicle must be in PARK (P) to recall the stored driving
positions. If your vehicle has a manual transmission and
the engine is running, the parking brake must be set to
recall the memory seat driving positions. The stored
driving positions can be recalled without setting the
parking brake if the vehicle is off.
Press one of the numbered memory buttons to recall the
stored setting. Each time a memory button is pressed, a
single beep will sound.
Three chimes will sound and the setting will not be
recalled if you press button 1 or 2 while the engine is
running and the vehicle is not in PARK (P) on an
automatic transmission or the parking brake is not
set on a manual transmission.
If you would like the stored driving positions to be
recalled when unlocking your vehicle with the remote
keyless entry transmitter or when you place the key in
the ignition, see ªVehicle Programming and
Personalization Featuresº in the Index.
To stop recall movement of the memory feature at any
time, press one of the power seat or mirror controls.

exit positions:
1. Press memory seat button 1 or the button with
the unlock symbol on the remote keyless entry
transmitter with the number 1 on the back to recall
the drive position.
2. Adjust the driver's seat to the desired exit position.
3. Press and hold the exit button located above
buttons 1 and 2 on the driver's door armrest for
at least three seconds.
Two beeps will sound to confirm that the exit
position has been saved.
4. Repeat the procedure for a second driver using
memory seat button 2 or the remote keyless entry
transmitter with the number 2 on the back.To recall the stored exit positions, press and release the
exit button. One beep will sound, and the seat will move
to the previously stored exit position for the currently
identified driver. If an exit position has not been stored
for this driver, the seat will move all the way back. The
position of the outside mirrors is not stored or recalled
for the exit position.
If your vehicle has an automatic transmission, the
vehicle must be in PARK (P) to recall the exit positions.
For a manual transmission, the parking brake must
be set if the engine is running to recall the stored
exit positions.
Three chimes will sound and the exit setting will not be
recalled if you press the exit button while the engine is
running and the vehicle is not in PARK (P) on an
automatic transmission or the parking brake is not set on
a manual transmission.
If you would like your stored exit position to be recalled
when unlocking the vehicle with the remote keyless
entry transmitter or when the ignition is turned off and
the driver's door is opened, see ªVehicle Programming
and Personalization Featuresº in the Index.

CAUTION:
When an air bag inflates, there is dust in the air.
This dust could cause breathing problems for
people with a history of asthma or other
breathing trouble. To avoid this, everyone in the
vehicle should get out as soon as it is safe to do so.
If you have breathing problems but can't get out
of the vehicle after an air bag inflates, then get
fresh air by opening a window or a door.
Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the air
bags inflate (if battery power is available). You can lock
the doors again and turn the interior lamps off by using
the door lock and interior lamp controls. The hazard
warning flashers will also come on when the air bags
deploy. If you want to turn them off, press the hazard
warning flasher button twice.In many crashes severe enough to inflate 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 inflate only once. After an
air bag inflates, 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 records information about the readiness
of the system, when the system commands air bag
inflation and driver's safety belt usage at deployment
or in a near
-deployment crash. The module also
records speed, engine rpm, brake and throttle data.

Let only qualified 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.

Trunk Lid
CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't 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 ªComfort Controlsº
in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
Remote Trunk Release Button
The remote trunk release
button is located on the
lower portion of the
driver's door.
To use this feature, an automatic transmission must
be in PARK (P) or NEUTRAL (N) and your manual
transmission must be in NEUTRAL with the parking
brake set.
Press the button to open the trunk. You can also press
the button with the trunk symbol on the remote keyless
entry transmitter to open the trunk.
When the trunk lid opens, a light inside the trunk
will come on. The light will go out when the trunk
lid is closed.

2-22
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.

2-24
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.
