Of course, traction is reduced when water, snow, ice,
gravel or other material is on the road. For safety, you’ll\
want to slow down and adjust your driving
to these
conditions.
It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction,
try
your best to avoid sudden steering, acceleration or
braking (including engine braking by shifting
to a lower
gear).
Any sudden changes could cause the tires to
slide.
You may not realize the surface is slippery until
your vehicle is skidding. Learn to recognize warning
clues
-- such as enough water, ice or packed snow on
the road
to make a “mirrored surface” -- and slow
down when you have any doubt.
Remember: Any anti-lock brake system
(ABS) helps
avoid only the braking skid.
Driving at Night
Night driving is more dangerous than day driving. One
reason is that some drivers
are likely to be impaired -- by
alcohol or
drugs, with night vision problems or by fatigue.

You will find an ENGINE COOLANT HOT-IDLE
ENGINE message
or a STOP ENGINE ENGINE
OVERHEATED message on the DIC. There is also an
engine temperature warning light
on the instrument
panel. See “Engine Temperature Warning Light” in the
Index.
Overheated Engine Protection Operating
Mode
Y
Should a low coolant condition exist and the message
STOP ENGINE
ENGINE OVERHEATED is displayed,
an overheat protection mode which alternates firing
groups
of four cylinders helps prevent engine damage.
This operating mode
allows your vehicle to be driven
to a safe place in
an emergency; you may drive up to
50 miles (80 km). Towing a trailer in the overheat
protection mode should be avoided.
I NOTICE:
After driving in the Overheated Engine
Protection Operating Mode,
to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil may be
severely degraded. Change the
oil and reset the
oil life indicator. See “Engine Oil, When to
~ Change” in the Index.

If you get the overheat warning but see or hear no
steam, the problem may not
be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
0 Idle for long periods in traffic.
Tow a trailer.
c
c
If you get the overheat warning with no sign of steam,
try this for
a minute or so:
1. Turn off your air conditioner.
2. Dial temperature control to the highest heat setting and open the window, as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- OVERDRIVE (a) or THIRD (3).
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes,
If the warning doesn’t come back on, you can drive
nonnally.
If the warning continues, pull over, stop
and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two
or three minutes while you’re parked, to see if
the warning stops.
But then, if you still have the
warning,
turn off the engine and get everyone out of the
vehicle
until it cools down. Also, see “Overheated
Engine Protection Operating Mode” listed previously in
this section.
You may decide not to lift the hood but to get &mice
help right away.

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.
Be sure you have sufficient knowledge,
experience, and the proper replacement
parts and tools before you attempt any vehicle maintenance task.
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 premiurn 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 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.

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.

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.

Finish Damage
Any stone chips, fractures or deep scratches in the finish should be repaired right away. Bare metal will corrode
quickly and may develop into a major repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your dealer or other service
outlets. Larger areas
of finish damage can be corrected
in your dealer's body and paint shop.
Underbody Maintenance c-
rc
Chemicals used for ice and snow removal and dust
control can collect on the underbody. If these are not
removed, accelerated corrosion (rust) can occur on the
underbody parts such as fuel lines, frame, floor pan and
exhaust system even though they have corrosion
protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud
and other debris can collect.
Dirt packed in closed areas
of the frame should be loosened before being flushed.
Your dealer or
an underbody car washing system can do
this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces
on your vehicle. This damage
can take two forms: blotchy, ringlet-shaped discolorations, and small irregular dark spots etched into
the paint surface.
Although no defect in the paint job causes this, Cadillac
will repair, at no charge to the owner, the surfaces of
new vehicles damaged by this fallout condition within
12 months or 12,OOO miles (20 000 km) of purchase,
whichever occurs first.

Service manuals contain diagnostic and repair
information for all chassis and body systems. They may
be useful for owners who wish to get a greater
understanding of their vehicle. They are also useful for
owners
with the appropriate skill level or training who
wish
to perform “do-it-yourself’ service. These are
authentic General Motors service manuals meant for
professional, qualified technicians.
Service Bulletins
Service bulletins covering various subjects are regularly
sent to all General Motors dealerships.
GM monitors
product performance in the field. When service methods are found which promote better service on
GM vehicles,
bulletins are created to help the technician perform
better
service. Service bulletins may involve any
number
of vehicles. Some will describe inexpensive service; others will describe expensive service. Some
will advise
of new or unexpected conditions, and others
may help avoid future costly repairs. Service bulletins
are meant for qualified technicians.
In some ,cases
bulletins refer
to service manuals, specialized tools,
equipment and safety procedures necessary
to service
the vehicle. Since these bulletins are issued throughout
the model year and beyond,
an index is required and
published quarterly to help identify specific bulletins.
Subscriptions
are available. You can order an index at
the toll-free numbers listed previously, or ask a
GM
dealer to see an index or individual bulletin.
Owner Publications
Owner’s manuals, warranty folders and various owner
assistance booklets provide owners
with general
operation and maintenance information.
