If your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label), it
is designed to operate on fuels that meet California
specifications. If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may turn
on and/or your vehicle
may fail
a smog-check test. If this occurs, return to your
authorized Geo dealer for diagnosis to determine the
cause
of failure. In the event it is determined that the
cause
of the condition is the type of fuels used, repairs
may
not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT);
ask your service station operator whether or not his
fuel
contains MMT. General Motors does not recommend the
use of such gasolines.
If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may be affected. The
malfunction indicator lamp on your instrument panel
may
turn on. If this occurs, return to your authorized
Geo dealer for service. To
provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and fuel
system, allowing your emission control system
to
function properly. Therefore, you should not have to add
anything to the fuel. In addition, gasolines containing
oxygenates, such
as ethers and ethanol, and
reformulated gasolines may be available in your area to
help clean the air. General Motors recommends that you
use these gasolines if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.

The cap is behind a hinged door on the passenger’s side
of your vehicle. On four-door models, use the key to the
vehicle to unlock the
fuel door.
To take off the cap, turn it slowly
to the left
(counterclockwise).
1 /1 CAUTION:
If you get gasoline on yourself and then
something ignites it, you could be badly burned.
Gasoline can spray out on you
if you open the
fuel filler cap
too quickly. This spray can happen
if your tank is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any “hiss” noise
to stop. Then unscrew
the cap all the
way.
Be careful not to spill gasoline. Clean gasoline from
painted surfaces
as soon as possible. See “Cleaning the
Outside of Your Geo”
in the Index. When you
put the cap back on, turn it to the right
(clockwise)
until you hear at least three clicks. 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.
I
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 or have proper
venting. 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.

Battery
Every new Geo has a Delco Freedom@ battery. You
never have
to add water to one of these. When it’s time
for a new battery, we recommend a Delco Freedom
battery. Get
one that has the replacement number shown
on the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days
or more, take
off the black, negative (-) cable from
the battery. This will help keep your battery from
running down.
A CAUTION:
Also, for your audio system, see “Theft-Deterrent
Feature”
in the Index.
Bulb Replacement
See “Replacement Bulbs” in the Index to check the size
and type
of bulb you need to use.
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.
I ,.I CAUTIdN:
Halogen bulbs have pressurized gas inside and
can burst
if you drop or scratch the bulb. You or
others could be injured. Be sure to read and
follow the instructions on the bulb package.

Tire Chains
NOTICE:
Use tire chains only where legal and only when
you must. Use only
SAE Class “S” type chains
that are the proper size for your tires. Install them
on the tires
of the drive axle (fourwheel-drive
vehicles can use chains on both axles).
Tighten them as tightly as possible with the ends
securely fastened. Drive slowly and follow the
chain manufacturer’s instructions.
If you can
hear the chains contacting your vehicle, stop
and retighten them.
If the contact continues,
slow down until it stops. Driving too fast or
spinning the wheels with chains on will
damage your vehicle.
Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can burst into flame if you strike a
match or get them on
a hot part of the vehicle. Some are
dangerous if you breathe their fumes in a closed space.
When you
use anything from a container to clean your
Geo, be sure to follow the manufacturer’s warnings and
instructions. And always open your doors or windows
when you’re cleaning the inside.
Never use these to clean your vehicle:
0 Gasoline
0 Benzene
0 Naphtha
0 Carbon Tetrachloride
Acetone
0 Paint Thinner
Turpentine
0 Lacquer Thinner
0 Nail Polish Remover
They can all be hazardous
-- some more than
others
-- and they can all damage your vehicle, too.
