Here you will find information about the care of your Cadillac. This
Section begins
with service and fuel information, and then it shows how
to check important fluid and lubricant levels. There is also technical
information about your vehicle, and a section devoted
to its appearance
care.

Doing Your Own Service Work
If you want to do some of your own service wax, you’ll want to get the
proper Cadillac Service Manual. It tells you much more about how to
service your Cadillac than this manual can.
To order the proper service
manual, see “Service Publications” 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.

A CAUTION:
You can be injured 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 premium unleaded gasoline rated at 91 octane or higher. It should
meet specifications ASTM
D4814 in the US. and CGSB 3.5-92 in
Canada. These fuels should have the proper additives,
so you should not
have to add anything to the fuel.
In the
U.S. and Canada, it’s easy to be sure you get the right kind of
gasoline (unleaded). You’ll see “UNLEADED” right on the pump. And
only unleaded nozzles will fit into your vehicle’s filler neck.
Be sure the posted octane is at least 91.
If the octane is less than 91, you
may get a heavy knocking noise when you drive.
(In an emergency, you
may be able
to use lower octane -- as low as 87 -- if heavy knocking does
not occur.)
If you’re using 91 or higher octane unleaded gas and you still
get heavy knocking, your engine needs service.

Downloaded from www.Manualslib.com manuals search engine What about gasoline with blending materials that contain oxygen, such as
MTBE or alcohol?
MTBE is “methyl tertiary-butyl ether.” Fuel that is
no more than 15%
MTBE is fine for your car.
Ethanol is ethyl or grain alcohol. Properly-blended fuel that is no more
than
10% ethanol is fine for your car.
Methanol is methyl or wood alcohol.
Gasolines for Cleaner
Air
Your use of gasoline with detergent additives will help prevent deposits
from forming in your engine and fuel system. That helps keep
your
engine in tune and your emission control system working properly. It’s
good for your vehicle, and you’ll be doing your part for cleaner air.
Many gasolines are
now blended with materials called oxygenates.
General Motors recommends that you use gasolines with these blending
materials, such as
MTBE and ethanol. By doing so, you can help clean
the air, especially in those parts of the country that have high carbon
monoxide levels.
In addition, some gasoline suppliers are now producing reformulated
gasolines. These gasolines are specially designed to reduce vehicle
emissions. General Motors recommends that you use reformulated
gasoline.
By doing so, you can help clean the air, especially in those parts
of the country that have high ozone levels.
You should ask your service station operators if their gasolines contain
detergents and oxygenates, and if they have been reformulated to reduce
vehicle emissions.

If you plan 6n driving in another country outside the U.S. or Canada,
unleaded fuel may be hard to find.
Do not use leaded gasoline. If you use
even one tankful, your emission controls won’t
work well or at all. With
continuous use, spark plugs can get fouled, the exhaust system can
corrode, and your engine
oil can deteriorate quickly. Your vehicle’s
oxygen sensor
will be damaged. All of that means costly repairs that
wouldn’t be covered by your warranty.
To check on fuel availability, ask an auto club, or contact a major oil
company that does business in the country where you’ll be driving.
You can also write us at the following address for advice. Just tell
us
where you’re going and give your Vehicle Identification Number (VIN).

FILLING YOUR TANK
263

Downloaded from www.Manualslib.com manuals search engine I
A CAUTION:
Gasoline vapor is highly flammable. It burns violently, and that
can cause very bad injuries. Don't smoke if you're near gasoline
or refueling your vehicle. Keep sparks, flames, and smoking
materials away from gasoline.
If you're refueling your tank using a hydrocarbon recovery nozzle, the
fuel pump may shut off before the
fuel capacity of your tank reaches full.
This
is a normal condition. If you slow the flow of fuel going into the
tank, it is more likely to fill to capacity without shutting off.
The cap is behind a hinged door
on the left side of your vehicle. Pushin
on the front edge
of the door to open.

release lever located
on the left side in the
trunk. Pull the lever
toward the rear
of your
vehicle to release the
fuel door.
To take off the cap, turn it slowly to the left (counterclockwise).
While refueling, hang the cap inside the fuel door.
A CAUTION:
If you get gasoline on you and then something ignites it, you
could be badly burned. Gasoline can spray out on you if you
open the fuel filler 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.
When you put the cap back on, turn it
to the right until you hear a
clicking noise.

A CAUTION:
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
