When should an air bag inflate?
The air bag is designed to inflate in moderate to severe
frontal or near-frontal crashes. The air bag will inflate
only
if the impact speed is above the system’s designed
“threshold level.”
If your vehicle goes straight into a
wall that doesn’t move or deform, the threshold level is
about
9 to 15 mph (14 to 24 km/h). The threshold level
can vary, however, with specific vehicle design,
so that
it can be somewhat above or below this range.
If your
vehicle strikes something that will move or deform, such
as a parked car, the threshold level will be higher. The
air bag
is not designed to inflate in rollovers, side
impacts or rear impacts, because inflation would not
help the occupant.
In any particular crash, no one can say whether an air
bag should have inflated simply because of
the damage
to a vehicle or because
of what the repair costs were.
Inflation is determined by the angle of the impact and
the vehicle’s deceleration. Vehicle damage
is only one
indication of this.
What makes an air bag inflate?
In a frontal or near-frontal impact of sufficient severity,
the air bag sensing system detects that the vehicle is
suddenly stopping as a result of a crash. The sensing
system triggers a chemical reaction
of the sodium azide
sealed
in the inflator. The reaction produces nitrogen
gas, which inflates the air bag. The inflator, air bag and
related hardware are all part
of the air bag module
packed inside the steering wheel.
How does an air bag restrain?
In moderate to severe frontal or near-frontal collisions,
even belted occupants can contact the steering wheel.
The air bag supplements the protection provided by
safety belts. Air bags distribute the force of the impact
more evenly over the occupant’s upper body, stopping
the occupant more gradually. But air bags would not
help you
in many types of collisions, including
rollovers, rear impacts and side impacts, primarily
because
an occupant’s motion is not toward the air bag.
Air bags should never be regarded
as anything more
than a supplement to safety belts, and then only in
moderate to severe frontal or near-frontal collisions.

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.
Be sure you have sufficient knowledge, experience, and 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.
Fuel
Use regular unleaded gasoline rated at 87 octane or
higher. At a minimum, it should meet specifications
ASTM D4814 in the United States and CGSB 3.S-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 compared to other gasolines.
Be sure
the posted octane is at least 87. 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 87 octane or higher and you
still 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.
If your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label),
it is designed to operate on fuels that meet California
specifications. If such fuels are not available
in states
adopting California emissions standards, your vehicle
will operate satisfactorily
on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may turn
on and/or your vehicle
may fail a smog-check test. If this occurs, return to
your authorized Oldsmobile retailer for diagnosis to
determine the cause of failure. In the event
it is
determined that the cause of the condition
is the type of
fuels used, repairs may not be covered by your warranty.

NOTICE:
If you need a new cap, be sure to get the right
type. Your retailer can get one for you.
If you get
the wrong type, it may not fit or have proper
venting, and your fuel tank and emissions system
might be damaged.
Checkhg Things Under the Hood
/I CAUTION:
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan.

Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or others
could be burned. Be careful not to drop or spill
things that will burn onto
a hot engine.

Tire Chains,
I NOTICE:
Use tire chains only where legal and only when
you must. Use only
SAE Class “S” type chains
that are the proper size for your tires. Install
them on the front tires and tighten them as
tightly as possible with the ends securely
fastened. Drive slowly and follow the chain
manufacturer’s instructions.
If you can hear the
chains contacting your vehicle, stop and retighten
them. If the contact continues,
slow down until it
stops. Driving too fast or spinning the wheels
with chains on will damage your vehicle.
Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can burst into flame if you strike a
match or get them on a
hot part of the vehicle. Some are
dangerous if you breathe their fumes in a closed space.
When you use anything from a container to clean your
Oldsmobile, be sure to follow the manufacturer’s warnings and instructions.
And always open your doors
or windows when you’re cleaning the inside.
Never use these to clean your vehicle:
Gasoline
0 Benzene
0 Naphtha
0 Carbon Tetrachloride
Acetone
0 Paint Thinner
0 Turpentine
Lacquer Thinner
0 Nail Polish Remover
They can all be hazardous
-- some more than
others
-- and they can all damage your vehicle, too.
Don’t use any of these unless this manual says you can.
In many uses, these will damage your vehicle:
0 Alcohol
0 Laundry Soap
0 Bleach
0 Reducing Agents
