2-78 Voltmeter
You can read battery
voltage on your voltmeter.
If it reads less than 11 volts
or more than 16 volts while
your engine is running, and
it stays there, you may have
a problem with the
electrical charging system.
Have it checked right away. Driving with the voltmeter
reading in a warning zone could drain your battery.
If you idle your engine for a while, the voltmeter
reading might move into the low voltage zone (indicated
by red dots). If the reading stays in the low voltage zone
while you are driving, you may have a problem with the
electrical charging system. Have it checked. While the
voltmeter reads in the low voltage zone, your battery
may not be able to power certain electrical accessories,
like ABS. (If this happens, your ABS INOP light will
come on. See ªAnti
-Lock Brake System Warning Lightº
in this section.)If you must drive a short distance with the voltmeter
reading in a warning zone, turn off all your accessories,
including your air conditioning system and
audio system.
Brake System Warning Light
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on
briefly when you turn the
ignition key to RUN. If it
doesn't come on then, have
it fixed so it will be ready to
warn you if there's
a problem.

If the light comes on while you are driving, 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. If the light is still on, have the
vehicle towed for service. (See ªTowing Your Vehicleº
in the Index.)
CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you've
pulled off the road and stopped carefully, have
the vehicle towed for service.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light will stay on if your parking brake doesn't release
fully. If it stays on after your parking brake is fully
released, it means you have a brake problem.
Anti-Lock Brake System Warning Light
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 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 vehicle needs service. If the
light is on and the regular brake system warning light
isn't on, you still have brakes, but you don't have
anti
-lock brakes. Adjust your driving accordingly.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.

2-80 ASR (Acceleration Slip Regulation) System
Warning Light (Option)
This warning light should
come on briefly as you start
the engine. If the warning
light doesn't come on then,
have it fixed so it will be
ready to warn you if
there's a problem.
If it stays on, or comes on when you're driving, there
may be a problem with your ASR system and your
vehicle may need service. When this warning light is
on, the system will not limit wheel spin. Adjust your
driving accordingly.
The ASR system warning light will come on if you turn
the system off by pressing the ASR button located on
the console and the warning light will come on and stay
on. To turn the system back on, press the button again.
The warning light should go off. (See ªASR Systemº in
the Index for more information.)
If the ASR system warning light comes on and stays on
for an extended period of time when the system is
turned on, your vehicle needs service.
Low Traction Light
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
this light will come on.
If you have the ASR system, this light will also come on
when the system is limiting wheel spin. You may feel or
hear the system working, but this is normal. Slippery
road conditions may exist if the low traction light comes
on, so adjust your driving accordingly. The light will
stay on for a few seconds after the ASR system stops
limiting wheel spin.
The low traction light also comes on briefly when you
turn the ignition key to RUN. If the light doesn't come
on then, have it fixed so it will be there to tell you when
the anti
-lock brake system or ASR system is active.

2-81 Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves into the
red area, your engine is
approaching an
overheating condition.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.
Low Coolant Light ( 5.7L V8 Engine)
This warning light should
come on briefly while you
are starting your engine. If
the light doesn't come on,
have it repaired.
Your vehicle is equipped with a low coolant indicator
that is designed to detect when the coolant level drops
below the set limit. If the low coolant level sensor (on
the radiator) detects that the level drops while the engine
is running, the low coolant indicator will light and
remain lit until the ignition is turned to OFF. Check the
coolant level and add coolant as needed.
The low coolant light might stay on after filling the
radiator. Turn the ignition to OFF, then restart the engine
to verify that the low coolant light goes out. See ªEngine
Coolantº in the Index.

NOTICE:
Driving with the low coolant light on could cause
your vehicle to overheat. See ªEngine Overheatingº
in the Index. Your vehicle could be damaged, and it
wouldn't be covered by your warranty.
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.
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.

2-83
NOTICE:
Modifications made to the engine, transmission,
exhaust 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.
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.

2-88 Check Gages Light
This warning light will
come on briefly when you
start the engine.
If the light comes on and stays on while you are driving,
check your gages to see if they are in the warning areas.
Hatch Ajar Light
This warning light should
come on in your instrument
panel for a three
-second
bulb check when you first
start your vehicle. If the
light doesn't come on, have
it serviced.
This light will stay on steady if your hatch is open or
ajar and the ignition key is in RUN.
Fuel Gage
Your fuel gage tells you
about how much fuel you
have left when the ignition
is on.
When the indicator nears E (empty), you still have a
little fuel left, but you should get more soon.
Page 145 of 376

Here are four things that some owners ask about. All
these things are normal and do not indicate that anything
is wrong with the fuel gage.
At the gas station, the gas pump shuts off before the
gage reads F (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 pointer may move while cornering, braking
or speeding up.
The gage may not indicate E (empty) when the
ignition is turned off.
Low Fuel Light
If your fuel is low, your vehicle's CHECK GAGES light
on your instrument panel cluster will come on.
Reduced Engine Power Light
(V6 Engine Only)
The REDUCED ENG PWR
warning light should come
on in your instrument panel
for a three
-second bulb
check when you first start
your vehicle.
If the light doesn't come on, have it serviced.
If the REDUCED ENG PWR warning light comes on, a
noticeable reduction in the vehicle's performance may
occur. The vehicle may be driven at a reduced speed
while the REDUCED ENG PWR light is on, but
acceleration and speed may be reduced. Anytime this
warning light stays on, the vehicle should be taken to an
authorized Chevrolet dealer as soon as possible for
diagnosis and repair.
