2004 CADILLAC DEVILLE Owners Manual

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.

Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the air
bag systems. To purchase a service manual, seeService
Publications Ordering Information on page 7-12.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
air bag can still inate during improper
service. You can be injured if you are close to
an air bag when it inates. Avoid yellow
connectors. They are probably part of the air
bag systems. Be sure to follow proper service
procedures, and make sure the person
performing work for you is qualied to do so.
The air bag systems do not need regular maintenance.
Restraint System Check
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)

Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems in
your vehicle. A damaged restraint system may
not properly protect the person using it,
resulting in serious injury or even death in a
crash. To help make sure your restraint
systems are working properly after a crash,
have them inspected and any necessary
replacements made as soon as possible.
If you have had a crash, do you need new belts or
LATCH system parts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be if worn
during a more severe crash, then you need new parts.
If the LATCH system was being used during a more
severe crash, you may need new LATCH system parts.If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have LATCH
system, safety belt or seat parts repaired or replaced.
New parts and repairs may be necessary even if the belt
or LATCH system was not being used at the time of
the collision.
If an air bag inates, you will need to replace air bag
system parts. See the part on the air bag system earlier
in this section.
If the frontal air bags inate, you will also need to
replace the driver’s and right front passenger’s safety
belt buckle assembly. Be sure to do so. Then the
new buckle assembly will be there to help protect you in
a collision.
After a crash you may need to replace the driver and
front passenger’s safety belt buckle assemblies, even if
the frontal air bags have not deployed. The driver
and front passenger’s safety belt buckle assemblies
contain the safety belt pretensioners. Have your safety
belt pretensioners checked if your vehicle has been
in a collision, or if your air bag readiness light stays on
after you start your vehicle or while you are driving.
SeeAir Bag Readiness Light on page 3-50.

{CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons. A child or
others could be badly injured or even killed.
They could operate the power windows or
other controls or even make the vehicle move.
If they turned the ignition to ACCESSORY or
ON and moved the shift lever out of PARK (P),
that would release the parking brake.
Don’t leave the keys in a vehicle with children.

There is a master key that works all of the lock cylinders
(driver’s door, trunk, ignition and glove box).
There is also a VALET key which only operates the
driver’s door and the ignition.Your vehicle has the PASS-Key
®III vehicle theft
system. Both the master and VALET key have a
transponder in the key head that matches a decoder in
the vehicle’s steering column. If a replacement key
or any additional key is needed, you must purchase this
key from your dealer. The key will have PK3 stamped
on it. Keep the bar code tag that came with the original
keys. Give this tag to your dealer if you need a new
key made.
Any new PASS-Key
®III key must be programmed before
it will start your vehicle. SeePASS-Key®III on page 2-21
for more information on programming your new key.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
In an emergency, contact Cadillac Roadside Assistance.
SeeRoadside Service on page 7-6.
If your vehicle is equipped with the OnStar
®system with
an active subscription and you lock your keys inside
the vehicle, OnStar
