Air bags are designed to inflate only once. After they
inflate, 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 a crash sensing and
diagnostic module, which records information about
the air bag system. The module records information
about the readiness
of the system. when the
sensors are activated and driver’s safety belt usage
at deployment.
Let
only qualified technicians work on your air
bag system. Improper service can mean that your
air bag system won’t work properly. See your dealer
for service.
NOTICE:
If you damage the covering for the driver’s air
bag, it may not work properly. You
may have to
replace the air bag module.
Do not open or break
the air bag covering.
Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts
of the air bag system in several places
around your vehicle. You don’t want
the system to
inflate while someone is worlung on your vehicle.
Your dealer and the Cadillac Service Manual have
information about servicing your vehicle and the air bag
system.
To purchase a service manual, see “Service and
Owner Publications” in
the Index.
I A CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected,
an air
bag can still inflate during improper service. You
can be injured if you
are close to an air bag when
it inflates. Avoid yellow connectors. They are
probably part of the air bag system.
Be sure to
follow proper service procedures, and make sure
the person performing work for you is qualified
to do so.
The air bag system does not need regular maintenance.

Downloaded from www.Manualslib.com manuals search engine Safety Belt Extender
If the vehicle’s safety belt will fasten around you, you
should use it.
But if
a safety belt isn’t long enough to fasten, your
dealer will order you an extender.
It’s free. When you go
in to order it, take the heaviest coat you will wear,
so the
extender will be long enough for you. The extender will
be just for you, and just for the seat
in your vehicle that
you choose. Don’t let someone else use it, and use it
only for the seat it is made to fit. To wear it, just attach it
to the regular safety belt.
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
If you’ve had a crash, do you need new belts?
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 belts.
If belts are cut or damaged, replace them. Collision
damage also may mean
you will need to have safety belt
or seat parts repaired or replaced. New parts and repairs
may be necessary even if the belt wasn’t being used at
the time of the collision.
If an air bag inflates, you’ll need to replace air bag
system parts. See the part on the air bag system earlier
in this section.

by pressing the INFO button. The normal range is
11.5 to 15.5 volts when the engine
is running.
BATTERY VOLTAGE LOW - 6: This message will
appear when the electrical system is charging less than
10 volts or if the battery has been drained. If this
message appears immediately after starting,
it is possible
that the generator can still recharge the battery. The
battery should recharge and may take a few hours to do
so. Consider using an auxiliary charger to boost the
battery after returning home or to a final destination.
(Be sure to follow the manufacturer’s instructions
when using a battery charger.)
If this message appears and stays on while driving or
after starting your vehicle, have it checked immediately
to determine the cause of this problem. To help the

brakes but you will still have the use
of manual brakes.
The power brakes will not be affected if the problem is
caused by a failed sensor. Have your vehicle serviced
immediately at your dealership.
CHANGE ENGINE OIL - 82: This means that the
life of the engine oil has expired and it should be
changed within
200 miles (322 km). See “Engine Oil”
and “Filter Recommendations” in the Maintenance
Schedule booklet. After an oil change, the Oil Life
Indicator must be reset. See “Oil Life Indicator”

a Be sure the parking brake has released.
You really should not park your vehicle, with a trailer
attached, on
a hill. If something goes wrong, your rig
could start
to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever
have to park your rig on a hill, here’s
how to
do it:
1. Apply your regular brakes, but do not shift into
PARK (P).
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then shift into
5. Release the regular brakes.
PARK (P) firmly and apply your parking brake.
When You Are Ready to Leave After
Parking on
a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belt, cooling system and brake adjustment.
Each
of these is covered in this manual, and the Index
will help you find them quickly. If you’re trailering, it’s
a good idea to review these sections before you start
your trip.
Check periodically
to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating”
in the Index.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
You can be injured and your vehicle could be
damaged
if you try to do service work on a
vehicle without knowing enough about
it.
0 Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused.
If you use
the wrong fasteners, parts can later break
or
fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your dealer before adding equipment
to the outside of
your vehicle.
Fuel
Use premium unleaded gasoline rated at 91 octane or
higher for best performance. You
may use middle grade
or regular unleaded gasolines, but your vehicle may not
accelerate as well.
At a minimum, the gasoline you use should meet
specifications ASTM
D4814 in the United States and
CGSB 3.5-M93 in Canada. Improved gasoline
specifications have been developed by the American
Automobile Manufacturers Association (AAMA) for
better vehicle performance and engine protection.
Gasolines meeting
the AAMA specification could
provide improved driveability and emission control
system protection Fompared to other gasolines.
Be sure the posted octane for premium is at least
9
1 (at least 89 for middle grade and 87 for regular). If
the octane is less than
87, you may get a heavy knocking
noise when
you drive. If it’s bad enough, it can damage
your engine.
If you’re using fuel rated at the recommended octane or
higher and you hear heavy knocking, your engine needs
service. But don’t worry if
you hear a little pinging
noise when you’re accelerating or driving up a hill.
That’s normal, and
