Your Cadillac dealer knows your vehicle best and wants
you to be happy with it. We hope you’ll go to your
dealer for all your service needs. You’ll get genuine GM
parts and GM-trained and supported service people.
We hope you’ll want to keep your GM vehicle all GM.
Genuine GM parts have one
of these marks: Your
vehicle has an air bag system. Before attempting
to
do your own service work, see “Servicing Your Air
Bag-Equipped Cadillac” 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 Maintenance
Schedule booklet.

Doing Your Own Service Work
If you want to do some of your own service work, 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 and Owner Publications’’
in the Index. 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.
0 Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
0 Be sure to use the proper nuts, bolts ana
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.

Downloaded from www.Manualslib.com manuals search engine Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your Cadillac dealer before adding equipment to the
outside of your vehicle.
Fuel
Use premium unleaded gasoline rated at 91 octane
or higher. At a minimum,
it should meet specifications
ASTM D4814
in the United States and CGSB 3.5-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 for premium 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 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 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 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 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.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT);
ask your service station operator whether or not this fuel
contains
MMT. General Motors does not recommend
the use of such gasolines. If fuels containing MMT
are used, spark plug life may be reduced and your
emission control system performance may be affected.
The malfunction indicator lamp on your instrument
panel may turn on. If this occurs, return to your
authorized Cadillac dealer for service.

Downloaded from www.Manualslib.com manuals search engine To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to
add anything to the fuel. In addition, gasolines
containing oxygenates, such as ethers and ethanol,
and reformulated gasolines may be available in your
area to help clean the air. General Motors recommends
that you use these gasolines
if they comply with the
specifications described earlier.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended in the previous text on
fuel. Costly repairs
caused by use of improper fuel 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
Vehicle Identification Number
(VIN).
NOTICE: advice. Just tell us where you’re going and give your
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty. General Motors International Product Center

Downloaded from www.Manualslib.com manuals search engine Filling Your Tank The cap is behind a hinged door on the driver’s side of
your vehicle.
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.
The fuel door release
button is located to the
left
of the steering wheel
next to the headlamp
knob
and on the Remote Keyless
Entry (RKE) transmitter. The button only
works in
PARK
(P) when the ignition
key is in any position.

Downloaded from www.Manualslib.com manuals search engine An alternate fuel door
release
is located inside of
the trunk on the left hand
side. Pull it
to release the
fuel door.
To take off the cap, turn it slowly to the left
(counterclockwise).
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 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.
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.
Hang the cap inside the fuel door while refueling.

Downloaded from www.Manualslib.com manuals search engine When you put the cap back on, turn it to the right
(clockwise) until you hear
a clicking sound. 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 you get
the wrong type, it may not
fit or have proper
venting, and your fuel tank and emissions system
might be damaged.
Checking Thiw~s Under the Hood
A CAU I ION: I
r- - I
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.
