2001 CHEVROLET TRACKER Owners Manual

2-71 Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves to the
H (red) side, your engine
is too hot.
It means that your engine coolant has overheated and
you should stop your vehicle and turn off the engine as
soon as possible.
The ªProblems on the Roadº section of this manual
shows what to do. See ªEngine Overheatingº in
the Index.
Malfunction Indicator Lamp
(Service Engine Soon Light)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (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.
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.

2-72
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.
NOTICE:
Modifications made to the engine, transmission,
exhaust, intake or fuel system of your vehicle or
the replacement of the original tires with other
than those of the same Tire Performance Criteria
(TPC) can affect your vehicle's emission controls
and may cause the SERVICE ENGINE SOON
light to come on. Modifications to these systems
could lead to costly repairs not covered by your
warranty. This may also result in a failure to pass
a required Emission Inspection/Maintenance test.
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 may be required.

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.

2-73
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:

Reducing vehicle speed.

Avoiding hard accelerations.

Avoiding steep uphill grades.

If you are 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 ªIf the Light Is On Steadyº following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see ªIf the Light
Is On Steadyº 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 recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See ªFilling Your Tankº in the Index.
The diagnostic system can determine if the fuel cap
has been left off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere. A few driving trips with the cap properly
installed 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. See ªFilling Your Tankº in the Index. It will
take a few driving trips to turn the light off.

2-74
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
See ªFuelº 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.Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have or may
begin programs to inspect the emission control equipment
on your vehicle. Failure to pass this inspection could
prevent you from getting a vehicle registration.
Here are some things you need to know in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the SERVICE
ENGINE SOON light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on
-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen
if you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still
does not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center
to prepare the vehicle for inspection.

2-75 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.

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.

Sometimes when the engine is idling at a stop, the
light may blink on and off. This is normal.

If you make a hard stop, the light may come on
for a moment. This is normal.CAUTION:
Don't keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches fire. 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.

2-76 Four-Wheel-Drive Light (If Equipped)
This light comes on when
the ignition switch is on
and the transfer case lever
is in one of the four
-wheel
drive positions.
See ªFour
-Wheel Driveº in the Index.
Power Indicator Light (If Equipped)
This light comes on when
the power mode selector
switch is turned to ªPº
(power) with the ignition
switch in the ON position.
This light comes on as a check for approximately
five seconds when the ignition key is turned to ON
or START.
Overdrive Off Light (If Equipped)
This light comes on when
the automatic four
-speed
transmission has been
converted to the three
-speed
mode and the overdrive is
turned off.
This light also comes on as a check for approximately
five seconds when the ignition key is turned to ON
or START.

2-77 Fuel Gage
Your fuel gage shows about
how much fuel is in your
tank. When the gage first
indicates ªEº (empty), you
still have about one or two
gallons (4 to 8 L) of fuel left
in your tank, but you need
to get more right away.Here are four concerns some owners have had about the
fuel gage. All these situations are normal and do not
indicate that anything is wrong with the fuel gage.

At the gas station, the fuel pump shuts off before the
gage reads ªFº (full).

It takes more (or less) fuel to fill up than the gage
reads. For example, the gage reads half full, but it
took more (or less) than half of the tank's capacity
to fill it.

The gage moves a little when you turn, stop or
speed up.

When you turn the engine off, the gage doesn't go
back to E (empty).
