CHEVROLET CAVALIER 2002 3.G Owners Manual

2-70
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 CHECK
ENGINE 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.

2-71 Oil Pressure Light
If you have a low engine oil
pressure problem, this light
will stay on after you start
your engine, or come on
when you are driving. This
indicates that your engine is
not receiving enough oil.
The engine could be low on oil, or could have some
other oil problem. Have it fixed immediately.
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
ignition 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.

If you're idling at a stop sign, the light may blink on
and then off.

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.

2-72 Service Vehicle Soon Light
This light will come on
briefly when you turn
on the ignition.
It will stay on or come on if it detects a problem on the
vehicle. If this happens, see your dealer's service
department as soon as possible.
Passlock
Warning Light
United States Canada
This light will come on briefly when you turn the key
to START.
If the light flashes, the Passlock system has entered a
tamper mode. If the vehicle fails to start, see ªPasslockº
in the Index.
On vehicles equipped with the remote keyless entry system,
when the ignition is off and the security system is armed, the
light will flash to indicate that the security system is active.
If the light comes on continuously while driving and
stays on, there may be a problem with the Passlock
system. Your vehicle will not be protected by Passlock,
and you should see your dealer.
On vehicles equipped with remote keyless entry, the
Passlock warning light will flash to indicate that the
security system is active when the ignition is OFF and
the security system is armed.

2-73 Up-Shift Light (Manual Transaxle)
This light comes on
when you need to
shift to the next
higher gear. See
ªManual Transaxleº
in the Index.
United States Only
Check Gages Light
United States Canada
This light will come on briefly when you are starting the
engine. If it comes on and stays on while you are
driving, check your various gages to see if they are in
the warning zones or if you are low on fuel.
See ªEngine Coolant Temperature Gageº and ªFuel
Gageº in this section for more information.

2-74 Fuel Gage
United States Canada
Your fuel gage tells you about how much fuel you have
left. When the indicator nears empty, the CHECK
GAGES light will come on. You still have about
1.5 gallons (5.7 L) of fuel left, but you should get more
soon. See ªCheck Gages Lightº earlier in this section for
more information.Here are four things that some owners ask about. None
of these show a problem with your fuel gage:

At the service station, the gas pump shuts off before
the gage reads full.

It takes a little more or less fuel to fill up that the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the tank's capacity to fill
the tank.

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

The gage doesn't go back to empty when you turn
off the ignition.
For your fuel tank capacity, see ªCapacities and
Specificationsº in the Index.

Comfort Controls
This section tells you how to make your air system
work for you. With these systems, you can control the
ventilation and heating in your vehicle. Your vehicle
also has the flow
-through ventilation system described
later in this section.
Climate Control System
Fan Knob
The left knob selects the force of air you want.
Turn the knob clockwise to increase fan speed and
counterclockwise to decrease fan speed. To turn the
fan off, turn the mode knob all the way counterclockwise
to OFF. In any other setting, the fan will run continuously
with the ignition on. The fan must be on to run the air
conditioning compressor.
Temperature Knob
The center knob changes the temperature of the air
coming through the system. Turn this knob toward
red (clockwise) for warmer air. Turn it toward blue
(counterclockwise) for cooler air.
Mode Knob
The right knob has several settings to control the
direction of airflow. For each setting, set the
temperature to a comfortable setting.

3-3
(Maximum): For maximum cooling use this setting
to recirculate much of the air inside your vehicle and
send it through the instrument panel outlets. The air
conditioning compressor will run automatically in this
setting when it is needed to help cool the air in the
vehicle. Operation in this mode during periods of high
humidity and cool outside temperatures may result in
increased window fogging. If window fogging is
experienced, select the defrost mode.
(Vent): This setting brings in outside air and directs
it through the instrument panel outlets.
(Bi-Level): This setting brings in outside air
and directs it two ways. Some air is directed through
the instrument panel outlets. Most of the air is directed
through the floor ducts and a little to the defrost and
side window vents.
(Floor): This setting sends most of the air
through the ducts near the floor. The rest comes out
of the defroster and side window vents.
(Defog): This setting allows half of the air to go
to the floor ducts and half to the defroster and side
window vents.
(Defrost): This setting directs most of the air
through the defroster and side window vents. Some of
the air goes to the floor ducts. The air conditioning
compressor will run automatically in this setting when
it is needed to help dry the air in the vehicle. The A/C
indicator light will also be on in the setting.
Air Conditioning Compressor Button
Press the A/C button to operate the air conditioner
compressor. The indicator light above the button will
glow when the air conditioning compressor is running.
You don't have to press the button to run the compressor
in maximum or defrost.
It is normal for the A/C indicator light to come on while
in defrost.
Running the compressor will help reduce vehicle
interior fogging.

3-4 Air Conditioning
On very hot days, open the windows long enough to
let hot, inside air escape. This reduces the time it takes
for your vehicle to cool down, which should help
fuel economy.
For quick cool
-down on very hot days, use the
maximum mode setting with the temperature knob
all the way in the blue area. If this setting is used for
long periods of time, the air in your vehicle may become
too dry. The best cool
-down happens if you start in
one of the other modes and then switch to maximum.
For normal cooling on hot days, use vent with the
temperature knob in the blue area and the A/C button
pressed in. The system will bring in outside air and cool it.
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use bi
-level with the temperature knob in the
middle and the A/C button pressed in. The system will
bring in outside air and direct slightly warmer air to
your lower body. You may notice this temperature
difference more at some times than others.
Heating
On cold days, use floor with the temperature knob all
the way in the red area. The system will bring in outside
air, heat it and send it to the floor ducts.
Your vehicle has heat ducts that are directed toward
the rear seat. Keep the area under the front seats clear
of obstructions so the heated air can reach the rear
seat passengers.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside (0
F (
-18
C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See ªEngine Coolant
Heaterº in the Index.
Defogging and Defrosting
Your system has two settings for clearing the front
and side windows. To defrost the windows quickly,
use defrost with the temperature knob all the way
in the red area. To warm passengers while keeping the
windows clean, use defog.

3-5
To defog the side windows, set the right control to
bi
-level and the fan control to the highest setting.
To defog the side windows while using the air
conditioner, set the right control to bi
-level, the fan
control to the highest setting, and press the A/C button.
For both systems, aim the side vents toward the side
windows. For increased airflow to the side vents, close
the center vents.
Rear Window Defogger (If Equipped)
Press the button located
under the air conditioning
button to turn the defogger
on. It will turn itself off
after about 10 minutes.The rear window defogger uses a warming grid to
remove fog from the rear window. It is designed to
clear the center of the rear window first.
If you turn it on again, the defogger will only run for
about five minutes before turning off. You can also turn
it off by pressing the button again.
Do not attach a temporary vehicle license across the
defogger grid on the rear window.NOTICE:
Don't use a razor blade or anything else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn't be covered by your warranty.
