Warning Lights, Gages and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you
will see in the details on the next few pages, some
warning lights come on briefly when
you start the
engine just
to let you know they’re working. If you are
familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with
one of your vehicle’s functions. Often gages and
warning lights work together to let you know when
there’s
a problem with your vehicle. When
one of the warning lights comes
on and stays on
when you
are driving, or when one of the gages shows
there may be a problem, check the section that tells YOU
what to do about it. Please follow this manual’s advice.
Waiting to
do repairs can be costly -- and even
dangerous.
So please get to know your warning lights
and gages. They’re a big help.

When the key is turned to
ON or STAFtT, a light will
come on for about eight
seconds to remind people to
fasten their safety belts.

belt is already buckled, a
chime will also sound.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR
BAG. The system checks the
air bag’s electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes the air bag sensors, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the air bag system, see “Air
Bag” in the Index.
AIR
BAG
You will see this light flash
for a few seconds when you
turn your ignition to
ON or
START. Then the light
should go out. This means
the system is ready.
If the
air bag readiness light doesn’t come on when you
start your vehicle, or stays on, or comes on when you
are driving, your
air bag system may not work properly.
Have your vehicle serviced right away.
Charging System Light
This light will come on
briefly when you turn on the
ignition, but the engine is
not running, as a check to
show you it is working.
Then it should go out when
the engine starts.
If the light stays
on or comes on while you are driving,
you
may have a problem with the electrical charging
system. It could indicate that you have a loose generator
drive belt
or another electrical problem. Have it checked
right away. Driving while this light
is on could drain
your battery.
If you must drive a short distance with this light on, be
certain to
turn off all your accessories, such as the radio

Anti-Lock Brake System Warning
Light (Option)
ABS
With the anti-lock brake
system, this light will come
on when you start your
engine and it will stay
on for three seconds.
That’s normal.
If the light flashes when you’re driving, you don’t have
anti-lock brakes and there could be a problem with your
regular brakes. Pull off the road and stop carefully.
You
may notice that the pedal is harder to push. Or, the pedal
may go closer to the floor. It may take longer to stop.
Have the vehicle towed for service. (See
“Towing Your
Vehicle” in the Index.)
Your regular brake system may not be working
properly if the anti-lock brake system warning light
is flashing. Driving with the anti-lock brake system
warning light flashing
can lead to an accident. After
you’ve pulled
off the road and stopped caremy,
have the vehicle towed for service.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition
off. Or, if the light comes on and stays on
when you’re driving, stop as soon as possible and
turn
the ignition off. Then start the engine again to reset the
system.
If the light still stays on, or comes on again
while you’re driving, your Geo needs service. If the
light
is on but not flashing and the regular brake system
warning light isn’t on,
you still have brakes, but you
don’t have anti-lock brakes.
The anti-lock brake system warning light should come
on briefly when you turn the ignitiorrkey to ON- If the
light doesn’t come on then, have it fixed so it will-be
ready to warn you
if there is a problem.

Malfunction Indicator Lamp
(Service Engine Soon Light)
SERVICE
ENGINE
SOON
Your Geo is equipped with
a computer which monitors
operation of the fuel,
ignition and emission
control systems.
This system is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended
to
assure that emissions are at acceptable levels for
the life
of the vehicle, helping to produce a cleaner
environment.
(In Canada, OBD I1 is replaced by
Enhanced Diagnostics.) The SERVICE ENGINE
SOON
light comes on to indicate that there is a problem and
service
is required. Malfunctions often will be indicated
by the system before any problem is apparent, which
may prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after
a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered
by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine
is not
running.
If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
0 Light Flashing -- A misfire condition has been
detected, A misfire increases vehicle emissions and
may damage the emission tontrol system on your
vehicle. Dealer or qualified service center diagnosis and service is required.
0 Light On Steady -- An emission control system
malfunction has been detected
on your vehicIe.
Dealer or qualified service center diagnosis and
service may be required.

If the Light Is Flashing
The following may prevent more serious damage to
your vehicIe:
Reduce vehicle speed.
Avoid hard accelerations.
@ Avoid steep uphill grades.
If towing a trailer, reduce the amount of cargo being
hauled as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light Is On Steady” following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Put your vehicle in PARK (P). Turn the
key
off, wait at least 10 seconds and restart the engine.
If the light remains on steady, see “If the Light Is On
Steady” following.
If the light is still flashing follow the
previous steps, and drive the vehicle to
your dealer or
qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction
by considering the following:
Did you
just put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap.
The diagnostic system can determine if the fuel
cap has been left off or improperly installed. This will
allow fuel to evaporate into
the atmosphere. A few
driving trips should
turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts
of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct
this
condition. Make sure to install the fuel cap properly. It
will take a few driving trips to turn the light off.

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality
will cause your
engine not to mn
as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
Oil Pressure Light
If you have a problem with
your oil, this light may stay
on after you start your
engine, or come
on when
you are driving.
If you experience this condition, change the fuel brand
you use. It will require at least one full tank of the
proper fuel to turn the light off.
If none of the above steps have made the light turn off, your engine properly lubricated and cool. The engine
