-
A CAUTION:
--
Never fill a portable fuel container while it is in
your vehicle, Static electricity discharge from the
container can ignite the gasoline vapor. You can
be badly burned and your vehicle damaged
if this
occurs. To help avoid injury to you and others:
Dispense gasoline only into approved
containers,
Do not fill a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed or
on any surface other than the ground.

Don’t smoke while pumping gasoline.
Checking Things Under the Hood
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.
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.

Downloaded from www.Manualslib.com manuals search engine How to Check
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.
I NOTICE:
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall on hot engine parts
or exhaust system parts, starting a fire. Be sure to
get an accurate reading if you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level
if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at
normal operating temperature, which is 180°F to
200°F (82°C to 93°C).
Get the vehicle warmed
up by driving about
15 miles (24 km) when outside temperatures are
above
50°F (10°C). If it's colder than 50°F ( 10°C),
you may have to drive longer.
Checking the Fluid Level

Park your vehicle on a level place. Keep the
engine running.
With the parking brake applied, place the shift
lever in PARK (P).
With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in each range. Then, position the
shift lever in PARK (P).
Let the engine
run at idle for three to five minutes.

Brake Fluid
Your brake master cylinder reservoir is here. It is filled
with
DOT-3 brake fluid.
There are only two reasons why the brake fluid level
in the
reservoir might go down. The first
is that the brake fluid
goes down to
an acceptable level during normal brake
lining wear. When new linings are put in, the fluid level
goes back up. The other reason is that fluid is leaking out of the brake system.
If it is, you should have your brake
system fixed,
since a leak means that sooner or later your
brakes won’t work well, or won’t work at all.
So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid won’t correct a leak.
If you add fluid
when your linings are worn, then you’ll have too much
fluid when you get new brake linings. You should add
(or remove) brake fluid, as necessary, only when work is
done on the brake hydraulic system.
If you have too much brake fluid, it can spill
on the engine. The fluid will burn if the engine
is hot enough.
You or others could be burned,
and your vehicle could be damaged. Add brake
fluid only when work is done on the brake
hydraulic system.
When your brake fluid falls to a low level, your brake warning light will come on. See “Brake System Warning
Light” in the Index.

Downloaded from www.Manualslib.com manuals search engine What to Add
When you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 11’ (GM Part
No. 12377967). Use new brake fluid from a sealed
container only.
Always clean the brake fluid reservoir cap and the
area around the
cap before removing it. This will help
keep dirt from entering the reservoir.
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.
NOTICE:
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.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid
on your vehicle.
If you do, wash it off
immediately. See “Appearance Care” in
the Index.
6-29

Downloaded from www.Manualslib.com manuals search engine Brake Wear
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).
r
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 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 Replacing L - -‘;e 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.
Your vehicle was designed and tested with top-quality
GM brake parts. 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 approved 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.
Battery
Every new Cadillac has an ACDelco Freedom@ battery.
You never have to add water to one
of these. When it’s
time for a new battery, we recommend an ACDelco
Freedom battery. Get one that has the replacement
number shown on the original battery’s label.
--‘-icle ~~~ Storage
lr’ you’re not going to drive your vehicle for 25 days
or more, remove the black, negative
(-) cable from
the battery. This will help keep your battery from
running down.
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren’t careful. See “Jump Starting” in the Index
for tips
on working around a battery without
getting hurt.
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
Also, for
your audio system, see “Theft-Deterrent
Feature” in the Index.

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
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.
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
or
-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.

Downloaded from www.Manualslib.com manuals search engine Headlamp Wiring
The headlamp wiring has an individual fuse which is
powered by a MaxiFuse?
An electrical overload will
cause the lamps to go on and
off, or in some cases to
remain
off. If this happens, have the headlamp wiring
checked right away.
MaxiFuse
is a registered trademark of Little Fuse ,
Incorporated.
Windshield Wiper Fuses
The windshield wiper motor is powered by a MaxiFuse.
If the motor overheats due to heavy snow, etc., the
wipers will stop until the motor cools.
If the overload,
is caused by some electrical problem, be sure to have
it fmed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load
is too heavy,
the cifcuit breaker opens and closes, protecting the circuit until the problem
is fixed or goes away.
MaxiFusesLRelay Center
The MaxiFuses and relays are located next to the engine
compartment fuse b1oc.k on the driver’s side
of the
engine.
To access the compartment fuse block, remove
the shroud cover.
If a MaxiFuse should blow, have your
vehicle serviced by your dealer immediately.
