9-1 Index
Here’s an alphabetical listing of almost every subject in this manual. You can use it to quickly find
something you want
to read.
i

If your vehicle ever gets into a lot of water -- such as
water up to the carpeting or higher
-- or if water enters
your vehicle and soaks the carpet, the air bag controller
can be soaked and ruined. If this ever happens, and then
you
start your vehicle, the damage could make the air
bags inflate, even if there’s no crash. You would have to
replace the air bags
as well as the sensors and related
parts.
If your vehicle is ever in a flood, or if it’s exposed
to water that
soaks the carpet, you can avoid needless
repair costs by turning
off the vehicle immediately.
Don’t let anyone start the vehicle, even to tow it, unless
the battery cables are first disconnected.
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 working on your vehicle. Your
dealer and the Bonneville 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
For up to 10 minutes 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.

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.
Tom 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.
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 your seat adjuster won’t work after a crash, the special
part of the safety belt that goes through the seat to the
adjuster may need to be replaced.
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.
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.)

If you can’t see the HUD image when the ignition is on,
check to see if:
0 The headlamps are on.
0 The HUD unit is covered.
0 The HUD dimmer control is adjusted correctly.
0 The HUD image is adjusted to the proper height.
A fuse in the fuse panel may be blown. See “Fuses
and Circuit Breakers” in the Index.
If the HUD image is not clear, it could be too bright.
Move the HUD dimmer control further downward. You
may need to clean the windshield and
HUD lens.
Your windshield is part of the HUD system. If you ever
have to have a new
windshield, be sure to get one
designed for HUD. If you don’t, the HUD image may
look blurred
and out of focus.

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;
0 Shift into a gear; and
0 Release the parking brake.
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(s), 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

fight.
-
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating”
in the Index.

Service
Your dealer knows your vehicle best and wants you to
be happy with it. We hope you’ll go to your dealer for
all your service needs. You’ll get genuine GM
parts and
GM-trained and supported service people.
We hope you’ll want to keep your GM vehicle
all GM.
Genuine GM
parts have one of these marks:

Doing Your Own Service Work
If you want to do some of your own service work, you’ll
want to use the proper Pontiac Service Manual. It tells
you much more about how
to service your vehicle than
this manual can. To order the proper service manual, see
“Service and Owner Publications” in the Index.
Your vehicle has an
air bag system. Before attempting
to do
your own service work, see “Servicing Your Air
Bag-Equipped Vehicle” in the Index.
You should keep a record with all
parts receipts and
list the mileage and the date of any service work you
perform. See “Maintenance Record” in the Index.
6-2

/1 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
The 8th digit of your vehicle identification number
(VIN) shows the code letter for your engine. You will
find the VIN at the top left
of your instrument panel.
(See .“Vehicle Identification Number”
in the Index.)
If you have the 3800 engine (VIN Code K), use regular
unleaded gasoline rated at 87 octane or higher. 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 you don’t have to buy a higher octane fuel to get
rid of pinging. It’s the heavy, constant
knock that means you have a problem.
