knock that means you have a problem.
If your vehicle is certified to meet California Emission
Standards (indicated
on the underhood emission control
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 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 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.
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.
I 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.

What to Do with Used Oil
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 oiI
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies
of water. Instead, recycle
it by taking
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.

Your vehicle 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).
I A CAUTION:
The brake wear warning sound means that soon
your brakes won’t work well. That could lead to
an accident, When you hear the brake wear
warning sound, have your vehicle serviced.
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.
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 Section 7 of the
Maintenance Schedule booklet under Part
C “Periodic
Maintenance Inspections.”
Brake Pedal Travel
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.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.

Downloaded from www.Manualslib.com manuals search engine When It’s Time for New Tires
~ One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires have
only 1/16 inch (1.6 mm) or
less of tread remaining.
You need a new tire if any
of the following statements
are true:
You can see the indicators at three or more places
around the tire.
You can see cord or fabric showing through the tire’s
rubber.
The tire has a bump, bulge or split.
The tire has a puncture, cut or other damage that
can’t be repaired well because
of the size or location
of the damage.
Buying New Tires
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,
get ones with that same
TPC Spec number. That way
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
TPC Spec number, make sure they are the same size,
load range, speed rating and consiruction type (bias,
