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. The button
only works in PARK (P)
when the ignition key is in
any position.
An alternate fuel door
release
is located inside of
the trunk on the left hand
side. Pull it to release
the
fuel door.

What to ,Add
When
you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 11@ (GM Part
No. 1052535). Use new brake fluid from a sealed
container only,
and always clean the brake fluid
reservoir cap before removing
it.
A CAUTION:
With the wrong kind of fluid in your brake
system, your brakes
may not work well, or they
may not even work
at all. This could cause a
crash. Always use the proper brake fluid.
Using the wrong fluid can badly damage brake
system parts. For example, just
a few drops of
mineral-based oil, such as engine oil, in your
brake system can damage brake system
parts
so badly that they’ll have to be replaced. Don’t
let someone put in the wrong kind
of fluid.
NOTICE: (Continued) NOTICE:
(Continued)
If you spill brake fluid on your vehicle’s painted
surfaces, the paint finish can
be damaged. Be
carefbl not to spill brake
fluid on your vehicle.
If you do, wash it off immediately. See
“Appearance Care” in the Index.
Brake Wear
Your Cadillac has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a
high-pitched warning sound when the brake pads are
worn
and new pads are needed. The sound may come and
go or be heard all the time your vehicle is moving (except
when you are pushing on the brake
pedal fmly).
A CAUTION:
The brake wear warning sound means that sooner
or later your brakes won’t work well. That could
lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.

Downloaded from www.Manualslib.com manuals search engine I NOTICE:
Continuing to drive with worn-out brake pads
could result
in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied
or lightly
applied. This does not mean something is wrong with
your brakes.
Free movement of brake calipers and proprely torqued
wheel nuts are necessary
to help prevent brake
pulsation. When tires are rotated, inspect brake calipers
for movement, brake pads for wear, and evenly torque wheel nuts in the proper sequence to
GM Specifications.
Brake linings should always
be replaced as complete
axle sets.
Brake Pedal Travel Brake Adjustment
Every time you apply the brakes, with
or without the
vehicle moving,
your brakes adjust for wear.
Replacing Brake System Parts
The braking system on a modem vehicle is complex.
Its many parts have to
be of top quality and work well
together if the vehicle
is to have really good braking.
Vehicles
we design and test have top-quality GM brake
parts in them, as your Cadillac does when it is new.
When you replace
parts of your braking system -- for
example, when your brake linings wear down and you
have to have new ones put in
-- be sure you get new
genuine
GM replacement parts. If you don’t, your
brakes may no longer work properly. For example, if
someone puts in brake linings that are wrong for your
vehicle, the balance between your front and rear brakes
can change -- for the worse. The braking performance
you’ve come to expect can change in many other ways if
someone puts in the wrong replacement brake
parts.
--
See your dealer if the brake pedal does not return to
normal height,
or if there is a rapid increase in pedal
travel.
This could be a sign of brake trouble.

NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right. It’s not. If your tires
don’t have enough air (underinflation),
you can
get the following:
, Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Needless damage from road hazards.
i Rough ride
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be
at
60 psi (420 Wa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell
if your tires are properly inflated
simply by
looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and moisture.
Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10 OOO to 13 000 km) for any signs of unusual wear.
If unusual wear is present, rotate your tires as soon
as
possible and check wheel alignment. Also check for
damaged tires
or wheels. See “When It’s Time for New
Tires” and “Wheel Replacement” later
in this section for
more information.

The purpose of regular rotation is to achieve more
uniform wear
for all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services”
in the Maintenance Schedule
booklet for scheduled rotation intervals.
When rotating
your tires, always use the correct rotation
pattern
shown here.
Don’t include the compact spare
tire in your tire rotation. After
the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” in
the Index.
A CAUTION:
Rust or dirt on a wheel, or on the parts to which
it is fastened,
can make wheel nuts become loose
after
a time. The wheel could come off and cause
an accident. When
you change a wheel, remove
any rust
or dirt from places where the wheel
attaches to the vehicle. In an emergency,
you can
use a cloth or a paper towel to do this; but be I
sure to use a scraper or wire brush later, if you
need to, to get
all the rust or dirt off. (See I
“Changing a Flat Tire” in the Index.)

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
Mixing tires could cause you to lose control while
driving.
If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and you could have a crash.
Using tires of different sizes
may also cause
damage to your vehicle. Be sure
to use the same
size
and type tires on all four wheels.
It’s all right
to drive with your compact spare,
though. It
was developed for use on your vehicle.
Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance. (This applies only to vehicles sold
in the United States.) The
grades are molded on the sidewalls
of most passenger
car tires. The Uniform Tire Quality Grading system does
not apply to deep tread, winter-type snow tires,
space-saver or temporary
use spare tires, tires with
nominal rim diameters of 10 to 12 inches (25 to 30 cm),
or
to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may
vary with respect to these
grades, they must also conform to Federal safety
requirements and additional General Motors Tire
Performance Criteria
(TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course.
For
example, a tire graded 150 would wear one and a half
(1 1/2) times as well on the government course as a tire
graded
100. The relative performance of tires depends
upon the actual conditions of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences in
road characteristics and climate.

r-
Traction -- A, B, C
The traction grades, from highest to lowest, are A, B
and C, and they represent the tire’s ability to stop on wet
pavement
as measured under controlled conditions on
specified government test surfaces
of asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based
on braking (straightahead) traction tests and does not
include cornering (turning) traction.
Temperature -- A, B, C
The temperature grades are A (the highest), B and C,
representing the tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure.
The grade
C corresponds to a level of performance
which
all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109. Grades
A and B represent higher levels of performance on the
laboratory test wheel than the minimum required by law. Warning: The temperature grade for this tire
is
established for a tire that
is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup
and possible tire failure.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully
at the factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to have your wheels
aligned again. However, if you notice unusual tire wear
or your vehicle pulling one way or the other, the
alignment may need to
be reset. If you notice your
vehicle vibrating when driving
on a smooth road, your
wheels may need
to be rebalanced.

Downloaded from www.Manualslib.com manuals search engine Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded.
If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced.
If the
wheel leaks air, replace it (except some aluminum
wheels, which can sometimes
be repaired). See your
Cadillac dealer if
any of these conditions exist.
Your dealer will know the kind
of wheel you need.
Each new wheel should have the same load carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new GM original
equipment parts. This way, you will
be sure to have the
right wheel, wheel bolts and wheel nuts for your Cadillac
model.
A CAUTION:
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose
air and make you
lose control. You could have
a collision in which
you or others could be injured.
Always use
the correct wheel, wheel bolts and wheel nuts
for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer/odometer
calibration, headlamp aim, bumper height, vehicle
ground clearance and tire
or tire chain clearance
to
the body and chassis.
See “Changing
a Flat Tire” in the Index for
more information.

Used Replacement Wheels
Putting
a used wheel on your vehicle is
dangerous.
You can’t know how it’s been used or
how many miles it’s been driven. It could
fail
suddenly and cause an accident. If you have to
replace a wheel, use a new GM original
equipment wheel.
Tire Chains
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.

Downloaded from www.Manualslib.com manuals search engine Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and
tar, tree sap, bird
droppings, chemicals from industrial chimneys, etc., can
damage your vehicle’s finish if they remain
on painted
surfaces. Wash the vehicle as soon
as possible. If
necessary, use non-abrasive cleaners that are marked
safe for painted surfaces to remove foreign matter.
Exterior painted surfaces are subject
to aging, weather
and chemical fallout that can take their toll over a period
of years.
You can help to keep the paint finish looking
new
by keeping your Cadillac garaged or covered
whenever possible.
Aluminum or Chrome Wheels
Keep your wheels clean using a soft clean cloth with
mild soap and water. Rinse with clean water. After
rinsing thoroughly, dry with a soft clean towel.
A wax
may then
be applied.
The surface
of these wheels is similar to the painted
surface
of your vehicle. Don’t use strong soaps,
chemicals, abrasive polishes, abrasive cleaners or
abrasive cleaning
brushes on them because you could
damage the surface. You
may use chrome polish on
chrome wheels, but avoid any painted surface of the
wheel, and buff off immediately after application. Don’t
take your vehicle through an automatic car
wash
that has silicon carbide tire cleaning brushes. These
brushes can also damage the surface
of these wheels.
Tires
To clean your tires, use a stiff brush with a tire cleaner.
I NOTICE:
When applying a tire dressing, always take care
to wipe
off any overspray or splash from all
painted surfaces on the body or wheels
of the
vehicle. Petroleum-based products
may damage
the paint finish.
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material to the parts repaired or
replaced to restore corrosion protection.
