check engine CHEVROLET TRACKER 1997 Owners Manual

NOTICE:
Your engine is designed to work with the
electronics
in your vehicle. If you add electrical
parts or accessories, you could change the
way
the engine operates. Before adding electrical
equipment, check with your dealer.
If you don’t,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part
of this manual that tells how to do it
without damaging your vehicle. See “Towing
Your Vehicle” in the Index.
Automatic Transmission Operation
There are several different positions for your shift lever.
PARK (P): This locks your rear wheels. It’s the best
position
to use when you start your engine because your
vehicle can’t move easily.

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.
Safety Belt Reminder Light
When the key is turned to
ON or START, a light will
come on for about eight
seconds to remind people to
fasten their safety belts.
Unless the driver’s safety
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
This light will come on
when you start your engine,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away. The air
bag readiness light should flash for a few
seconds when
you turn the ignition key 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.
Charging System Light
4
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
and air conditioner.

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. This 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:
Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control 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 vehicle.
Dealer or qualified service center diagnosis and
service may be required.

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 run 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.
If you experience one or more of these conditions,
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,
have your dealer or qualified service center check the
vehicle.
Your dealer has the proper test equipment and
diagnostic tools to
fix any mechanical or electrical
problems that may have developed.
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.
This indicates that there is not enough pressure to keep
your engine properly lubricated and cool. The engine
could be low on
oil, or have some other oil related
problem. Have
it fixed right away.
The
oil light could also come on in three
other situations.
0 When the ignition is on but the engine is not running,
the light will come on as a test to show you it
is
working, but the light will go out when you turn the
engine to START. If it doesn’t come on with the
ignition on, you may have a problem with the fuse or
bulb. Have it fixed right away.

0 Sometimes when the engine is idling at a stop, the
light may blink on and
off. This is nonnal.
If you make a hard stop, the light may come on for a
moment. This is normal.
I I
A CAUTIPN:
I
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fie. You or others could be burned.
Check your oil as soon
as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
Power Indicator Light (If Equipped)
POWER
This light comes on when
the power mode selector
switch
is turned to
POWER (P) with the
ignition switch in the
ON position.

To help avoid hearing loss or damage:
0 Adjust the volume control to the lowest setting.
0 Increase volume slowly until you hear comfortably
and clearly.
NOTICE:
Before you add any sound equipment to your
vehicle
-- like a tape player, CB radio, mobile
telephone or two-way radio
-- be sure you can add
what you want.
If you can, it’s very important to
do it properly. Added sound equipment may
interfere with the operation of your vehicle’s
engine, Delco radio or other systems, and even
damage them. Your vehicle’s systems may
interfere with the operation
of sound equipment
that has been added improperly.
So, before adding sound equipment, check with
your dealer and be sure to check Federal rules
covering mobile radio and telephone units.
Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes
or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight and
extreme heat. If they aren’t, they may not operate
properly or may cause failure
of the tape player.
Your tape player should be cleaned regularly after every
50 hours of use. Your radio may display CLN to indicate
that
you have used your tape player for 50 hours without
resetting
the tape clean timer. If this message appears on
the display, your cassette tape player needs to be
cleaned. It will still play tapes, but you should clean it as
soon
as possible to prevent damage to your tapes and
player. If you notice a reduction
in sound quality, try a
known good cassette to see if it is the tape or the tape
player at fault.
If this other cassette has no improvement
in sound quality, clean the tape player.

Avoid needless heavy braking. Some people drive in
spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear
out much faster if you
do
a lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances,
you will
eliminate a lot
of unnecessary braking. That means
better braking and longer brake life,
If your engine ever stops while you’re driving, brake
normally but don’t pump your brakes. If you do, the
pedal may get harder
to push down. If your engine
stops, you will still have some power brake assist. But
you will use it when
you brake. Once the power assist is
used up,
it may take longer to stop and the brake pedal
will be harder to push.
Anti-Lock Brakes (Option)
Your vehicle may have anti-lock brakes (ABS). ABS is
an advanced electronic braking system that will help
prevent a braking skid.
ABS
If your vehicle has anti-lock
brakes, this warning light on
the instrument panel will
come on briefly when you
start your vehicle.
When you start your engine,
or when you begin to drive
away, your anti-lock brake system will check itself.
You
may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves a little. This is normal.
If there’s a problem with the anti-lock brake system,
the anti-lock brake system warning light will stay on or
flash. See “Anti-Lock Brake System Warning Light” in
the Index.

Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to move
slightly slower at night.
When you want to leave the freeway, move to the proper
lane well in advance. If you miss your exit, do not,
under any circumstances, stop and back up. Drive on to
the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
-- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready
to go. If it needs
service, have it done before starting out. Of course,
you’ll find experienced and able service experts in Geo
dealerships all across North America. They’ll be ready
and willing
to help if you need it.
Here are some things you can check before a trip:

Lamps: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should
you delay your trip a short
time
to avoid a major storm system?
Maps: Do you have up-to-date maps?

Highway Hypnosis
Is there actually such a condition as “highway hypnosis”?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack
of awareness, or whatever.
There is something about an easy stretch
of road with
the same scenery, along with the hum
of the tires on the
road, the drone
of the engine, and the rush of the wind
against the vehicle that can make you sleepy. Don’t let it
happen to you!
If it does, your vehicle can leave the
road in
less than a secund, and you could crash and
be injured
.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:
0 Make sure your vehicle is well ventilated, with a
comfortably cool interior.
0 Keep your eyes moving. Scan the road ahead
and
to the sides. Check your mirrors and your
instruments frequently.
0 If you get sleepy, pull off the road into a rest, service
or parking area and take a nap, get some exercise,
or
both. For safety, treat drowsiness on the highway as
an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.
