Seats & Restraint Systems
How The Air Bag System
Works (CONK)
e
e
Your vehicle is equipped with a
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 whether the
driver’s safety belt was in use.
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 cover for the
driver’s or
the right-front
passenger’s air bag, they may not
work properly. You may have to
replace the air bag on the steering
wheel or both the air bag and the
instrument panel for the passenger’s
air bag.
Do not open or break the air
bag covers.
Is the smoke from an air bag inflation
harmful?
The particles emitted during air bag
inflation are not harmful to most people.
Some people with respiratory ailments
may experience difficulty breathing if they
stay
in the vehicle with the windows
closed after air bag inflation.
So, if your air
bag inflates,
you and any passengers
should exit the vehicle
if and when it is
safe to
do so. If you or your passengers
can’t get out of
the vehicle, try to get fresh
air by opening a window, turning on the
fan, or opening a door.
Servicing Your Air
Bag-Equipped Pontiac
Air bags affect how your Pontiac should
be serviced. There are parts of the air bag
system in several places around xour
vehicle. You don’t want the system to
inflate while someone is working on your
vehicle. Your Pontiac dealer and the
1994
Bonneville Service Manual have
information about servicing your vehicle
and the air bag system. The air bag
system does not need regular
maintenance.
Safety Belt Use During
Pregnancy
Safety belts work for everyone, including
pregnant women. Like all occupants, they
are more likely to be seriously injured if
they don’t wear safety belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap portion should be worn as low as possible
throughout the pregnancy.

Understanding Radio
Reception
FM Stereo
FM Stereo will give you the best sound,
but
FM signals will reach only about
10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with
FM signals, causing the sound to come
and go.
AM
The range for most AM stations is greater
than for
FM, especially at night. The
longer range, however, can cause stations
to interfere with each other.
AM can also
pick up noise from things like storms and
power lines. To lower this noise, try
reducing the treble level.
Care of Your Cassette
Tape Player
A tape player that is not cleaned regularly
is subject
to reduced sound quality, ruining
the cassette, or damaging the mechanism.
Tape cassettes that are not properly stored
in their plastic cases away from
contaminants, direct sunlight, and extreme
heat may not operate properly and could
cause premature failure
of the tape player. Your
tape player should be cleaned after
every
50 hours of use, as regular
maintenance.
If you notice a reduction in
sound quality, try a good cassette to see if
the tape or the tape player is at fault.
If the
second cassette results in no improvement
in sound quality, try cleaning the tape
player.
Cleaning may be done with a scrubbing
action, non-abrasive cleaning cassette.
This system uses a cleaning cassette with
pads which scrub the tape head as
the
hubs of the cleaner cassette turn. It is
normal for the cartridge
to eject while
cleaning. Insert the cassette at least
3
times to ensure thorough cleaning. A
scrubbing action cleaning cassette is
available through your Pontiac dealership.
You may also choose a non-scrubbing
action, wet-type cleaner which uses a
cassette with a fabric belt to clean the tape
head. This type of cleaning cassette will
not eject. It may not clean as thoroughly
as the scrubbing type cleaner.

Parking on Hills
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.
2.
3.
4.
5.
Apply your regular brakes, but don’t
shift into
“P” (Park) yet.
Have someone place chocks under the
trailer wheels.
When the wheel chocks are in place,
release the regular brakes until the chocks absorb the load.
Reapply the regular brakes. Then
apply your parking brake, and then shift to
“F”’ (Park).
Release the regular brakes.
When You Are Ready to Leave After
Parking

Apply your regular brakes and hold
the pedal down while you:
0 Start your engine;
Shift into a gear; and
0 Release the parking brake.
Let up on the brake pedal.
Drive slowly until the trailer is clear
of the chocks.
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 are tight.

Doing Your Own Service
Work
If you want to do some of your own
service work, you’ll want to get the
proper Pontiac Service Manual. It tells
you much more about how to service your
Pontiac than this manual can.
To order the
proper service manual, see “Service 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 Pontiac”
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.
NOTICE:
~~
If you try to do your own service
work without knowing enough
about it, your vehicle could be
damaged.

Engine Accessory Belt
The 3800 (L27) engine uses an engine
accessory belt. This diagram shows the
features connected by the belt routing.
See “Maintenance Schedule’’
in the Index
for when to check the belt.

B. Crank
C. Coolant Pump
D. Air Conditioning
E. Alternator
F. Tensioner
3800 Supercharged
(L67) Engine (OPTION)
Your Bonneville may have a 3800
Supercharged engine. The Supercharger is
a device which is designed to pump more
air into the engine than
it would normally
use. This air mixed
with fuel, creates
increased engine power. Since the
Supercharger is a pump and is driven
from an engine accessory drive belt,
increased pressure is available at all
driving conditions, The Powertrain Control
Module
(PCM),
works with a vacuum control to regulate
the increased pressure required during
specific driving conditions. When this
increased pressure or boost is
not desired,
such as during idling and light throttle
cruising, the excess air that the
’
Supercharger is pumping is routed,through
a bypass. All of these controls, working
together provide high performance
character and fuel efficiency
in the3800
V6 Supercharged engine.
The power steering pump uses a Remote
reservoir mounted on the throttle wd
cruise control cable bracket. See
“Maintenance Schedule”
in the Index for
when you should check the fluid:

Check oil level every 30,000 miles
(50 000 km) or every 36 months.
What Kind of Oil to Use
See “Recommended Fluids and
Lubricants” in the Index and use only the
recommended oil.
