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 modules
packed inside the steering wheel and in the instrument
panel
in front of the right front passenger.
How does an air bag restrain?
In moderate to severe frontal or near-frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. 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.

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.
0 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 premium unleaded gasoline rated at 91 octane or
higher. At a minimum, it should meet specifications
ASTM
D4,814 in the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications have been
i ~ 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 for premium is at least 91. If
the octane is less than 91, you may get a heavy knocking
2
noise when you drive. (In an emergency, you may be
able to use
a lower octane -- as low as 87 -- if heavy
knocking does not occur.)
If you’re using 91 or higher
octane unleaded gasoline and you still hear heavy
knocking, your engine needs service.
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 inbcator 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 Cadillac dealer 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.

Downloaded from www.Manualslib.com manuals search engine If you get gasoline on yourself and then
something ignites it,
you could be badly burned.
Gasoline can spray out on you
if you open the
fuel fillet cap too quickly. This spray can happen
if your tank is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any “hiss” noise to stop. Then unscrew-
the cap all the way.
1 Be careful not to spill gasoline. Clean gasoline from
painted surfaces
as soon as possible. See “Cleaning the
Outside of Your Cadillac”
in the Index.
When you put the cap back on, turn it to the right until
you hear at least three clicks. Make sure you fully install the cap.
NOTICE:
If you need a new cap, be sure to get the.right
type. Your dealer can get one for you.
If yau get
the wrong type, it may not
fit or have proper
venting, and your fuel tank and emissions system
might be damaged.
Checking Things Under the Hood
I A 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.

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 flames
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
Cadillac, be sure to follow
the manufxturer’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
Naphtha
0 Carbon Tetrachloride
0 Acetone
Paint Thinner
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:
Alcohol
0 Laundry Soap
0 Bleach
Reducing Agents
