2. Get the vehicles close enough so the jumper cables
can reach, but
be sure the vehicles aren*t touching
each other.
If they are, it could cause a ground
connection you don't want.
You wouldn't be able to
start your vehicle,
and the bad grounding could
damage the electrical systems.
You co~~ld
be injured if the vehicles roll. Set the
parking
brake firmly on each vehicle. Put an
automatic transmission in PARK (P) or a manual
transmission
in NEUTRAL (N). If you have a
four-wheel-drive vehicle with a manual transfer case
shift lever, be sure
the transfer case is not in
NEUTRAL (Nj.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the ci, wsette
lighter, or accessory power outlets,
if you have this
option. Turn off all
lamps that aren't needed as well
as radios. This will avoid sparks and help save both
batteries.
In addition, it could save your radio!
I NOTICE:
If' you leave your radio on, it could be badly
damaged, The repair wouldn't be covered by
your warranty.
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools
away from any underhood
electric fan.

CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use a flashlight
if
you need more light.
Be sure the battery has enough water. You don't
need to add water to the Delco Freedom"' battery
installed in every new
CbI vehicle. But if a
battery has filler caps, be sure the right amount
of fluid is there. If it
is low, add water to take care
of that first. If
you don't, explosive gas could
be present.
Battery fluid contains acid that can burn you.
Don't get it on you. If you accidentally get it
in
your eyes or on your skin, flush the place with
water and get medical help immediately.
6. Connect the red
positive (+) cable to
the positive
(+) terminal
of the vehicle with the
de.ad battery.

Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See “Cleaning the
Outside of Your Vehicle” in the Index.
When you put the cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make sure
you fully install the cap. The diagnostic system can
determine if the fuel cap has been left off or improperly
installed. This would allow fuel to evaporate into the
atmosphere. See “Malfunction Indicator Lamp’’ in
the Index.
______
NOTICE:
If you need a new cap, be sure to get the right
type. Your dealer can get one for you.
If you get
the wrong type, it may not fit properly. This may
cause your malfunction indicator lamp to light
and your fuel tank and emissions system may be
damaged. See “Malfunction Indicator Lamp” in
the Index.
Checking Things Under the Hood
To open the hood, first pull
the handle inside the vehicle
on the lower driver’s side of
the instrument panel.
Then go to the front of
the vehicle and release the
secondary hood release.

How to Add Fluid
Here's how to add fluid. Refer to the Maintenance
Schedule to determine what kind
of fluid to use. See
"Recommended Fluids and Lubricants"
in the Index.
1. Remove the filler plug.
2. Add fluid at the filler plug hole. Add only enough
fluid to bring the fluid level up
to the bottom of the
filler plug hole.
3. Install the filler plug. Be sure the plug is fully seated.
Hydraulic Clutch
The hydraulic clutch system in your vehicle is
self-adjusting.
A slight amount of play ( 1/4 inch to
1/2 inch or ti lnm to 12 mm) in the pedal is normal.
It isn't a good idea to "top OW' your clutch fluid. Adding
fluid won't correct
a leak. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
When to Check and What to Use
Refer to the Maintenance Schedule. Owner Checks and
Services. to determine how often you should check the
fluid level
in your clutch master cylinder reservoir and
for the proper fluid. See "Owner Checks and Services''
and "Recommended Fluids and Lubricants"
in
the Index.

Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain in your vehicle
for 5 years or 150,000 miles
(240 000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem with
engine overheating, see “Engine Overheating” in
the Index.
A 50/50 mixture of water and the DEX-COOL@ coolant
for your vehicle will:
Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265 OF ( 129 O C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
8
they should.
NOTICE:
When .adding coolant, it is important that you use
only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL@ is added to
the system, premature engine, heater core
or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs
first. Damage caused by the use
of coolant other than DEX-COOL@ is not
covered by your new vehicle warranty.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half DEX-COOL@ coolant which
won’t damage aluminum parts. If you use this mixture,
you don’t need to add anything else.

Brake Wear
Your vehicle has front disc brakes and rear drum brakes.
If you have the all-wheel drive option, 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: I
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.
Your rear
drum brakes don't have wear indicators,
but
if you ever hear a rear brake rubbing noise: have
the rear brake linings inspected. Also, the rear brake
drums should be removed and inspected each time the
tires are removed
for rotation or changing. When you
have the front brake pads replaced. have the rear brakes
inspected, too.
Brake linings should always be replaced as complete
axle sets.
See
"Brake System Inspection" in Section 7 of this manual
under
Part C "Periodic Maintenance Inspections."
6-31

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 wheels.
It’s all right to drive with your compact spare
(if you have one). 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
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
c Urades, they rnust also conform to Federal safety
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
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 clilnate.

Fabric Protection Non-Greasy Stains
Your vehicle has upholstery and carpet that has been
treated with Scotchgard" Fabric Protector,
a 3M
product. It protects fabrics by repelling oil and water,
which are the carriers of most stains. Even
with this
protection, you still need
to clean your upholstery and
carpet often to keep
it looking new.
Further information on cleaning
is available by calling
1-800-433-3296 (in Minnesota, 1-800-642-6 167).
Special Cleaning Problems
Greasy or Oily Stains
Stains caused by grease. oil, butter. margarine, shoe
polish, coffee with cream, chewing
gum, cosmetic
creams, vegetable
oils, wax crayon, tar and asphalt can
be removed as follows:
1. Carefully scrape off excess stain.
2. Follow the solvent-type instructions
described earlier.
Shoe polish, wax crayon,
tar and asphalt will stain if left
on
;1 vehicle's seat fabric. They should be removed as
soon as possible. Be careful, because the cleaner will
dissolve them and may cause them to spread. Stains caused
by catsup, coffee (black). egg,
fruit. fruit
juice, milk, soft drinks, wine. vomit. urine and blood can
be removed
as follows:
1. CarefLlIly scrape off excess stain. then sponge the

Headlamps
The headlamp wiring is protected by an internal circuit
breaker. An electrical overload
will cause the lamps to go
on and
off, or in some cases to remain off. If this happens,
have
your headlamp wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit breaker
and a fuse.
If the motor overheats due to heavy snow, etc.. the
wiper will stop
until the motor cools. If the overload is caused
by some electrical problem, be sure
to get it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load is too heavy.
the circuit breaker opens and closes, protecting the
circuit
until the problem is fixed or goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by
a combination of fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance of fires caused by electrical problems.
Look
at the silver-colored band inside the fuse. If the
band is broken
or melted, replace the fuse. Be sure you
replace a bad fuse
with a new one of the identical size
and rating.
If you ever have a problem on the road and don't have a
spare fuse.
you can borrow one that has the same
amperage. Just pick
some feature of your vehicle that
you can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace
it as soon as you can.
Instrument Panel Fuse Block
The fuse block is at the
driver's end of the
instrument panel.
Remove the
toller by turning the fastener
counterclockwise. Extra fuses and the fuse extractor are
provided
in the cover. To reinstall the fuse panel cover.
push in and turn the fastener clockwise.
