Then go to the front of the vehicle and release the
secondary
hood release.
Lift the hood, release the hood prop from its retainer and
put the hood prop into the slot
in the hood. You may
have a lamp that cornes on when you lift the hood.
A CAUTION:
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.

Checking Transmission Fluid Cold
A cold check is made after the vehicle has been sitting
for eight hours or more
with the engine off and is used
only as a reference. Let the engine run at idle for five
minutes if outside temperatures are 50°F
(10°C) or
more. If it's colder than
50°F (IO'C), you may have to
idle the engine longer. Should the fluid level be
low
during a cold check, you must perform a hot check
before adding fluid. This will give
you a more accurate
reading
of 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 minutes or more. Then, without shutting
off the engine, follow these steps:
1. Flip
the handle up and then pull out the dipstick and
wipe
it with a clean rag or paper towel.
2. Push it back in all the way, wait three seconds and
then
pull it back out again.

When using concentrated washer fluid,
follow the manufacturer’s instructions for
adding water.
Don’t mix water with ready-to-use washer
fluid. Water can cause the solution to freeze
and damage your washer fluid tank and
other parts of the washer system. Also,
water doesn’t clean as well as washer fluid.
Fill your washer fluid tank only
three-quarters full when it’s very cold. This
allows for expansion if freezing occurs,
which could damage the tank if it is
completely full.
Don’t use radiator antifreeze in your
windshield washer. It can damage your
washer system and paint.
Brakes
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 fiist 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.

I CAUTION:
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.
Refer to the Maintenance Schedule to determine when to
check your brake fluid. See “Periodic Maintenance
Inspections”
in the Index.
Checking Brake Fluid
You can check the brake fluid without taking off the cap.
Just look at the windows
on the brake fluid reservoir.
The fluid levels should be above
MIN. If they aren’t,
have your brake system checked to see
if there is a leak.
After work
is done on the brake hydraulic system, make
sure
the levels are above MIN and below the top of
each window.

What to Add When
you do need brake fluid. use only DOT-3 brake
fluid
-- such as Delco Supreme I1 @ (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.
1 A CAUTION:
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.

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.

Brake Wear
Your Oldsmobile 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 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 this manual
under
Part C “Periodic Maintenance Inspections.”
Brake Pedal Travel
See your retailer 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 make a brake stop, your disc brakes
adjust for wear.
