engine and let
it run until you can feel the upper
radiator
hose getting hot. Watch out for the engine
fans.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower, add
more
of the proper mix to the coolant surge tank
until
the level reaches about 2.5 inches (60 mm)
below the base of the filler neck.

The compact spare is for temporary use only. Replace
the compact spare tire with
a full-size tire as soon as you
can. See the storage instructions label to replace your
compact spare into your trunk properly.
Compact Spare Tire
Although the compact spare tire was fully inflated when
your vehicle was new, it can lose
air after a time. Check
the inflation pressure regularly.
It should be 60 psi
(420 kPa).
After installing the compact spare
on your vehicle, you
should stop as soon as possible
and make sure your
spare tire is correctly inflated. The compact spare. is
made to perform well at posted speed limits for
distances up to
3,000 miles (5 000 km), so you can
finish your trip and have your full-size tire repaired
or
replaced where you want. Of course, it’s best to replace
your spare with a full-size tire as
soon as you can. Your
spare will last longer and be in
good shape in case you
need
it again.

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 part devoted
to its appearance care.
Service
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:
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.
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.

I A CAUTION:
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, 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 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 leasf
9 1. 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 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 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.

In Canada, some gasolines contain an octane-enhancing
additive called
MMT. If you use such fuels, your
emission control system performance may deteriorate
and the malfunction indicator lamp on your instrument
panel may turn
on. If this happens, return to your
authorized Cadillac dealer for service.
To provide cleaner air, all gasolines 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.
NOTICE:
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.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may
b.e 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
advice. Just tell us where you’re
going and give your
Vehicle Identification Number
(VIN).

you hear at least three clicks. Make sure you fully install
the
cap.
I 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 Things Under the Hood
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.
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 or others
could be burned.
Be careful not to drop or spill
things that will
burn onto a hot engine.

A CHECK OIL LEVEL message will appear when the
engine oil is approximately a quart low.
If the message
is displayed, check the dipstick level and add oil
as needed.
It's a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be
warm and the vehicle must be on level ground. The
engine oil dipstick is
located behind the radiator
on the
driver's side of the
engine. The black .handle
says
ENGINE OIL on it.
Turn
off the engine and give
the
oil a few minutes to
drain
back into the oil pan.
If you don't, the oil
dipstick might not show
the actual level.

Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
When to Add Oil
If the oil is at or below the ADD line, then you’ll need
to add some oil.
But you must use the right kind. This
part explains what kind of oil to use. For crankcase
capacity, see “Capacities and Specifications” in
the Index.
NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark
that shows the proper operating range,
your engine could be damaged.
