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.
In Canada, some gasolines contain an octane-enhancing
additive called
MMT. If you use such fuels, your
emission control system performance may deteriorate
and the malfunction indicator lamp
on your instrument
panel may turn
on. If this happens, return to your
authorized Chevrolet/Geo dealer for service.
To provide cleaner air, all gasolines 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.
1 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). When
you put the cap
back on, turn it to the right 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.
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.
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, and your fuel tank and emissions system
might be damaged.

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:
Gasoline
Benzene
Naphtha
0 Carbon Tetrachloride
Acetone
Paint Thinner
Turpentine
0 Lacquer Thinner
Nail Polish Remover
They can all be hazardous
-- some more than
others
-- and they can all damage your vehicle, too. Don’t use any
of these
unless this manual says you can.
In many uses, these will damage your vehicle:
Alcohol
Laundry Soap
Bleach
Reducing Agents
Cleaning the Inside of Your Geo
Use a vacuum cleaner often to get rid of dust and loose
dirt. Wipe vinyl or leather with a clean, damp cloth.
Your Geo dealer has two GM cleaners,
a solvent-type
spot
lifter and a foam-type powdered cleaner. They will
clean normal spots and stains
very well. Do not use
them on vinyl or leather.
Here
are some cleaning tips :
Always read the instructions on the cleaner label.
Clean up stains as soon as you can -- before they set.
Use a clean cloth or sponge,
and change to a clean area
often. A soft brush may be used if stains are stubborn.
Use solvent-type cleaners in a well-ventilated area
only. If you use them, don’t saturate the stained area.
If a ring forms after spot cleaning, clean the entire
area immediately
or it will set.
