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.

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.
