How To Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top of the reservoir clean, then unscrew the cap and
wipe the dipstick with a clean rag. Replace the cap and
completely tighten it. Then remove the cap again and
look at the fluid level
on the dipstick.
When the engine compartment
is hot, the level should be
at the MAX mark.
When the engine
compartment
is cool,
the level should be at
the MIN mark.
What to Use
To determine what kind of fluid to use, see
“Recommended Fluids and Lubricants”
in the Index.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use
a fluid that has sufficient
protection against freezing.

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.

Vehicle Identification Number (VIN)
II
I CODE +.- MODEL YEAR -PLANT I
This is the legal identifier for your Geo. It appears on a
plate in the front corner of the instrument panel, on the
driver’s side. You can see it if
you look through the
windshield from outside your vehicle. The
VIN also
appears on the Vehicle Certification and Service Parts
labels and the certificates of title and registration.
Engine Identification
The 8th character in your VIN is the engine code. This
code will help you identify your engine, specifications
and replacement parts.
Service Parts Identification Label
You’ll find this label inside the glove box on the door.
It’s very helpful
if you ever need to order parts. On this
label is:
0 your VIN,
0 the model designation,
0 paint information and
0 a list of all production options and special
Be sure that this label is not removed from the vehicle.

Electrical Equipment
I NOTICE:
Don’t add anything electrical to your Geo unless
you check with your dealer
first. Some electrical
equipment can damage your vehicle and the
damage wouldn’t be covered by your warranty.
Some add-on electrical equipment can keep other
components from working as they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your Geo, see “Servicing Your
Air Bag-Equipped Geo” in the Index.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by fuses, circuit breakers and thermal links
in the wiring itself.
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 correct size.
If you ever have a problem on the road and don’t
have a spare fuse, you can “borrow” one. 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 size you need. Replace it as
soon as you can.
Before replacing
a fuse, turn every vehicle electrical
switch
off.
Instrument Panel Fuse Block
This fuse box is under the left side of the instrument
panel. The fuses here protect each separate circuit
There are two fuse blocks
in your vehicle: the instrument
including headlamps. If you have failure,

Maintenance Schedule
Short Trip/City Definition
Follow the Short Trip/City Maintenance Schedule if any
one
of these conditions is true for your vehicle:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside

driving in stop-and-go traffic).
You frequently tow a trailer or use a carrier on top of
your vehicle.
If the vehicle is used for delivery service, police, taxi
or other commercial application.
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions
cause engine oil to breuk
