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
RUN
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.
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
“Anti-Lock Brake System Warning Light” 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.

(Service Engine Soon
Light)
Your Chevrolet is equipped
with a computer which
monitors operation
of the
SERVICE
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
0
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.
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.

The following may prevent more serious damage to
your vehicle:
Reduce vehicle speed.
0 Avoid hard accelerations.
0 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.

rn
In this section you'll find out how to operate the comfort
control and audio systems offered with your Chevrolet.
Be sure to read about the particular systems supplied
with your vehicle.
Comfort Controls
With this system, you can control the heating and
ventilation in your Chevrolet. If
you have the air
conditioning option, you can also control cooling.
Your vehicle also has the flow-through ventilation
system described later in this section.
Fan Control Knob
* FAN: Turn this knob to select the force of air
you want.
Temperature Control Knob
Turn the knob to change the temperature of the air
flowing from the heating system. Turn
it to the right for
warmer air and to the
left for cooler air. The temperature
of the air cannot be less than the temperature of the
outside air.

OFF: The system is off.
VENT Air flows through the upper air vents.
12 BI-LEVEL: Air is directed through the upper air
vents and the heater ducts.
'!A HEATER: This setting directs most of the air
through the heater ducts and some
of the air through the
windshield defroster vents.
9 BLEND: Air is directed through the windshield
defroster vents and the heater ducts.
DEFROST: This setting directs most of the air
through the windshield defroster vents and some of the
air through the heater ducts.
Air Conditioning (Option)
The air conditioning system uses the same controls as
the heating system, except that the air control knob has
two extra settings, described below.
MAX: Provides maximum cooling or quick cool-down
on very hot days. This setting recirculates most
of the air
inside your vehicle. If it is used for long periods
of time,
the air may become dry. This setting directs air through
the upper air vents.
A/C: Use for normal cooling on hot days. This setting
cools outside air and directs it through the upper
air vents.

Downloaded from www.Manualslib.com manuals search engine The air conditioner compressor operates in MAX, A/C,
BI-LEVEL, BLEND and DEFROST when the outside
temperature is above freezing. When the air conditioner
is
on, you may sometimes notice slight changes in your
vehicle’s engine speed and power. This is normal,
because the compressor uses power and the system is
designed to cycle the compressor on and off to keep the
desired cooling and help fuel economy.
Cooling
The air conditioner works best if you keep your
windows closed. On
very hot days, open the windows
just long enough for the hot air to escape.
1. Turn the air control knob to A/C for normal cooling.
For faster cooling, move the knob
to MAX.

Heating
The heater works best if you keep your windows closed
while using it.
1. Turn the air control knob to HEATER.
2. Turn the fan control knob to the desired speed.
3. Turn the temperature control knob to a
comfortable setting.
If your vehicle is equipped with an optional engine coolant
heater, you can use it in cold weather (around 20°F/-8”C
or lower) to improve heater performance on initial
start up.
Because an engine coolant heater warms the engine
coolant, your vehicles heating system can more quickly
and efficiently provide heat for your vehicle’s passenger
area. See “Engine Coolant Heater”
in the Index.
Bi-Level Heating
You may want to use bi-level heating on cool, but sunny
days. This setting directs
cool air toward your body and
warmer air toward your feet.
1. Turn the air control knob to BI-LEVEL.
2. Turn the temperature control knob to a
comfortable setting.
3. Turn the fan control knob to the desired speed.

Downloaded from www.Manualslib.com manuals search engine Of course, traction is reduced when water, snow, ice,
gravel or other material is
on the road. For safety, you’ll
want
to slow down and adjust your driving to these
conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving
on a surface with reduced traction, try
your best
to avoid sudden steering, acceleration or
braking (including engine braking by shifting
to a lower
gear). Any sudden changes could cause the tires to
slide.
You may not realize the surface is slippery until
your vehicle is skidding. Learn to recognize warning
clues
-- such as enough water, ice or packed snow on
the road to make a “mirrored surface”
-- and slow
down when you have any doubt.
Remember: Any anti-lock brake system
(ABS) helps
avoid
only the braking skid.
Driving at Night
Night driving is more dangerous than day driving. One
reason
is that some drivers are likely to be impaired -- by
alcohol or drugs, with night vision problems, or by fatigue.

If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving,
Idle for long periods in traffic.

try this for a minute or
so:
1. If you have an air conditioner, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (@)
or DRIVE (D) for automatic transmissions.
If you no longer have the overheat warning, you can drive.
Just
to be safe, drive slower for about 10 minutes. If the
warning doesn’t come back on, you can drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away. If
there’s still no sign
of steam, you can idle the engine
for two or three minutes while you’re parked,
to see
if the warning stops. But then,
if you still have the
warning,
turn 08 the engine and get everyone out of
the vehicle until it cools down.
You may decide not to lift the hood but to get service
help right away.
