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 (lO"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. Pull
out the dipstick and wipe it with a clean rag or
2. Push it back in all the way, wait three seconds and
paper
towel.
then pull it back out again.

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 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.
Refer to the Maintenance Schedule to determine when to
check your brake fluid. See “Periodic Maintenance
Inspections” in the Index.

Checking Brake Fluid What to Add
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
MTN and helow the top of
each window. 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.

Brake Wear
NOTICE:
0
0 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. Your Geo has
front disc brakes and rear drum 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
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.
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.
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 brakes 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”.
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 make a brake stop, your disc brakes
adjust for wear.
Replacing Brake System Parts
The braking system on a modern 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.

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 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.
Used Replacement Wheels
I A CAUTION:
Putting a used wheel on your vehicle is
dangerous.
You can’t know how it’s been used
or how far it’s been driven.
It could fail suddenly
and cause an accident.
If you have to replace a
wheel, use a new GM original equipment 1 wheel.
