Downloaded from www.Manualslib.com manuals search engine 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.
Use premium unleaded gasoline rated at
9 1 octane or
higher. At a minimum, it should meet specifications
ASTM D4814 in the United States and CGSB 3.5-WI93
in Canada. Improved gasoline specifications have been
developed by the American Automobile Manufacturers
Association
(AAMA) for better vehicle performance
and engine protection. Cholines 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 9 I. If
the octane is less than
91, you may get a heavy knockmg
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
rnethylcyclopentadienyl manganese tricarbonyi
(MMT);
ask your service station operator whether or not his 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
controa system performance may be affected. The
malfunction indicator
lamp on your instrument panel
may turn on. If this occurs, return to your authorized
Cadililac dealer fox service.

Don’t add anything to your oil. Your Cadillac dealer is
ready to advise if you tlunk something should be added.
Your Cadillac has an Oil Life Indicator. This feature
will let you
know when to change your oil and
filter
-- usually between 3,000 miles (5 000 km) and
7,500 miles
(12 500 km) since your last oil change.
Under severe conditions,
the indicator may come on
before 3,000 miles (5 000 km). Never drive your vehicle
more than 7,500 miles (12
500 km) or 12 months
(whichever occurs first) without an
oil change.
The system won’t detect dust
in the oil. So, if you
drive
in a dusty area, be sure to change your oil every
3,000 miles
(5 000 km) or sooner if the CHANGE
ENGINE OIL message comes on. Remember to reset
the Oil Life Indicator when the oil has been changed.
For more information, see “Oil Life Indicator”
in
the Index.
After
the oil has been changed, display the OIL LIFE
LEFT message by pressing the INFORMATION (INFO)
button. Then press and hold the RESET (INFO RESET)
button until the display shows “loo.” This resets the oil life
index. The message will remain
off until the next oil
change
is needed. The percentage of oil life remaining
may be checked at any time by pressing the
INFORMATION (INIFQ) button several times until
the OIL LIFE LEFT message appears. For more
information on the Oil Life feature, see “Oil Life
Indicator”
in the Index.

Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t let used
oil stay on your skin
for very long. Clean your skin and nails with soap and
water,
or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about the use and disposal
of oil products.)
Used oil can be
a real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from
the filter before disposal. Don’t ever dispose of oil
by putting
it in the trash, pouring it on the ground, into
sewers, or into streams QI- bodies of water. Instead,
recycle
it by takmg it to a place that collects used oil. If
you have
a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for help.

Follow these steps to reinstall the air cleaner assembly:
Slide the air cleaner lid into the slots in the front
edge
of the air cleaner base.
Pivot the
air cleaner cover and the air duct assembly
downward. Make sure that both latches are secure
and fully engaged.
Reinstall the clean air duct over the mass airflow
sensor. Make sure that the duct
is secure around the
entire outer edge of the sensor.
Tighten the air duct clamp.
Reconnect the
LA% sensor.
Refer to the Maintenance Schedule to determine when to
replace the
air filter.
See “Scheduled Maintenance Services” in the
Maintenance Schedule booklet.

Operating the engine with the air cleaner off
can cause you or others to be burned. The air
cleaner
not only cleans the air, it stops flames if
the engine backfires. If it isn’t there, and the
engine backfires, you could be burned. Don’t
drive with it off, and be careful working on the
engine
with the air cleaner off.
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.

A good time to check your automatic transaxle fluid
level
is when the engine oil is changed.
Change both
the fluid and filter every 50,000 miles
(83
000 km) if the vehicle is mainly driven under one or
more
of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90°F (32 O C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such
as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
See “Scheduled Maintenance Services”
in the
Maintenance Schedule booklet. Because this
operation can be
a little difficult, you may
choose
to have this done at your Cadillac dealership
service department.
If’ you do it yourself, be sure to follow all the instructions
here, or you could get
a false reading on the dipstick.

Downloaded from www.Manualslib.com manuals search engine 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 firmly).
The brake wear warning sound means that soon
your brakes won9$ work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
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.
Properly torqued
wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
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.
See “Brake System Inspection” in the Maintenance
Schedule booklet under Part
C “Periodic Maintenance
Inspections”.
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.
Every time you apply the brakes, with or without the
vehicle
moving, your brakes adjust for wear.

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.
Tires should
be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, 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.
I
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.

Downloaded from www.Manualslib.com manuals search engine To find out what kind and size of tires you need, look at
the Tire-Loading Information label.
The tires installed on
your vehicle when it was new had
a Tire Performance Criteria Specification
(TPC Spec)
number on each tire’s sidewall. When you get new tires,
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and
other things during normal service on
your vehicle. If your tires have an all-season tread
design, the TPC number will
be followed by an “MS”
(for mud and snow).
If you ever replace your tires with those not having a

Downloaded from www.Manualslib.com manuals search engine 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.
eadwear
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 haIf
( 1 1/2) times as well on the government course as a tire
upon the actual conditions of their use, however, and
may depart significantly from the norm due to variations
b Oraded 100. The relative performance of tires depends in
driving habits, service practices and differences in
road characteristics and climate.
action -- A9
The traction grades, from highest to lowest, are A, €3 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.
~~~~~~~~~~~ -ID A?
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.
