air condition CHEVROLET MONTE CARLO 2002 6.G Owners Manual

2-82
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.

2-83
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.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.

Comfort Controls
Dual ComforTemp
Climate Controls
The Dual ComforTemp Climate Control system allows
the driver and passenger to maintain separate temperature
settings for their seating areas. The system works best if
you keep your windows closed while using it.
Fan Knob
The knob on the left side of the climate control panel
regulates the fan speed. Turn the fan to 1 for low fan
speed and up to 5 for maximum fan speed.OFF: Turn the fan knob to OFF to turn off the system.
The fan must be on for the air conditioning compressor
to operate.
Driver's Temperature Lever
The lever on the left adjusts the air temperature on
the driver's side of the vehicle independent of the
temperature set by the passenger. Slide the lever
upward to raise the temperature. Slide the lever
downward to lower the temperature.
Passenger's Temperature Lever
The lever on the right adjusts the air temperature on
the passenger's side of the vehicle independent of the
temperature set by the driver. Slide the lever upward to
raise the temperature. Slide the lever downward to
lower the temperature.
Mode Knob
The knob on the right side of the control panel has
several settings to control the direction of airflow:
(Vent): This setting directs air through the
instrument panel outlets.

3-3
(Bi-Level): This setting directs air two ways.
Half of the air is directed through the instrument panel
outlets. Most of the remaining air is directed through the
floor vents and a small amount to the windshield
defroster and side window outlets.
(Floor): This setting sends most of the air through
the ducts near the floor. The remaining air comes out of
the defroster and side window outlets. The recirculation
button cannot be selected in this mode.
(Defogger): This setting sends half of the air to
the floor ducts and half to the defroster and side window
outlets. The air conditioning compressor will run
automatically in this setting unless the outside
temperature is below 40
F (4
C). The air inlet will also
be automatically set to outside air. The recirculation
button cannot be selected in this mode.
(Defroster): This setting directs most of the air
through the defroster and side window vents. Some of
the air also goes to the floor ducts. The air conditioning
compressor will run automatically in this setting unless
the outside temperature is below 40
F (4
C). The air
inlet will also be automatically set to outside air. The
recirculation button cannot be selected in this mode.Mode Buttons
(Outside Air): Press this button to force the
system to use outside air. This button is usable in all of
the air delivery modes on the right knob. An indicator
on the button will light up when this button is selected.
(Recirculation): Press this button to limit
the amount of outside air entering your vehicle. This
is helpful when you are trying to limit odors entering
your vehicle or when you are trying to cool your vehicle
quickly with air conditioning. This button can be used
in vent and bi
-level modes. An indictor on the button
will light up when this button is selected. The system
will default back to the outside air setting, so you will
have to reselect this setting every time you restart
your vehicle.
While in the recirculation mode the system may cause
fogging of the windows when the weather is cold and
damp. To clear the fog, select either the defogger or
defroster mode and increase the fan speed. To avoid
refogging of the windows, use the outside air setting.

3-4
A/C (Air Conditioning Compressor): Press this
button to turn the air conditioning compressor on and
off. An indicator light will glow on this button when the
air conditioning compressor is turned on. The system
will cool and dehumidify the air inside the vehicle when
the A/C light and fan are on.
Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time for the
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
For quick cool
-down on very hot days, select a fan setting,
turn the right knob on the control panel to vent mode,
press the air conditioning compressor and recirculation
buttons, and move the temperature control 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.
For normal cooling on hot days, turn the right knob on
the control panel to vent mode; press the air conditioning
compressor and the outside air buttons, and move the
temperature controls all the way in the blue area.
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.
To remedy this, turn the right knob on the control panel
to bi
-level mode. Press the air conditioning compressor
button and move the temperature controls to a
comfortable setting.
Heating
On cold days, turn the right knob on the control panel to floor
mode. Press the outside air button and move the temperature
controls all the way in the red area. The system will bring in
outside air, heat it and send it to the floor ducts.
Ventilation
For mild outside temperatures when little heating or
cooling is needed, turn the right knob on the control panel
to vent mode, press the outside air button, and move the
temperature controls to a comfortable setting. Your vehicle
also has the flow
-through ventilation system described
later in this section.
Defogging and Defrosting
Your system has two settings for clearing the front and side
windows. To defrost the windows quickly, turn the fan to the
highest setting, and use defroster with the temperature
indicator(s) all the way in the red area. To warm passengers
while keeping the windows clear, use defogger. For more
information, see ªRecirculationº in the Index.

3-6 Ventilation System
Adjust the amount of
airflow by moving the
thumbwheel located
underneath or on the sides
of the air vents. Change the
airflow direction by moving
the thumbwheel below the
vents to the right or left.
Your vehicle's flow
-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
compressor is running and the outside air button
is pressed.
If the airflow seems very low when the fan is adjusted to
the highest setting, regardless of the mode setting, your
passenger compartment air filter may need to be
replaced. See ªMaintenance Scheduleº and ªPassenger
Compartment Air Filterº in the Index.Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of your windows.

When you enter a vehicle in cold weather, adjust the
mode knob to floor and the fan to the highest speed
for a few seconds before driving off. This helps clear
the intake ducts of snow and moisture and reduces
the chance of fogging the inside of your windows.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all of its controls to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your audio
system even after the ignition is turned off. See
ªRetained Accessory Powerº in the Index.

5-10
Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your disabled vehicle towed. See
ªRoadside Assistanceº in the Index. If you want to
tow your vehicle behind another vehicle for recreational
purposes (such as behind a motorhome), see
ªRecreational Vehicle Towingº in the Index.
Engine Overheating
You will find a coolant temperature gage and a warning
message about a hot engine on your instrument panel
cluster. See ªEngine Coolant Temperature Gageº and
ªHot Coolant Temperature Messageº in the Index.
You also have a low coolant message on your instrument
panel cluster. See ªLow Coolant Level Messageº in
the Index.
Overheated Engine Protection
Operating Mode
This emergency operating mode allows your vehicle to
be driven to a safe place in an emergency situation. If an
overheated engine condition exists, an overheat protection
mode which alternates firing groups of cylinders helps
prevent engine damage. In this mode, you will notice a
significant loss in power and engine performance. The low
coolant light may come on and the temperature gage will
indicate an overheat condition exists. Driving extended
miles (km) and/or towing a trailer in the overheat
protection mode should be avoided.
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss, change the oil and reset
the oil life system. See ªEngine Oilº in the Index.

5-12
NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty. See ªOverheated
Engine Protection Operating Modeº in the Index.
If No Steam Is Coming From Your Engine
An overheat warning, along with a low coolant message
can indicate a serious problem. See ªLow Coolant
Messageº in the Index.
If you get an engine overheat warning with no low
coolant message, 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.

Tow a trailer.If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. If your air conditioner is on, 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 (D).
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, idle the engine for
three minutes while you're parked. If you still have the
warning, turn off the engine and get everyone out of
the vehicle until it cools down. Also, see ªOverheated
Engine Protection Operating Modeº listed previously
in this section.
You may decide not to lift the hood but to get service
help right away.

6-4 Gasoline Specifications
It is recommended that gasoline meet specifications
which were developed by the American Automobile
Manufacturers Association and endorsed by the
Canadian Vehicle Manufacturers' Association for better
vehicle performance and engine protection. Gasolines
meeting these specifications could provide improved
driveability and emission control system performance
compared to other gasolines.
In Canada, look for
the ªAuto Makers'
Choiceº label on
the pump.
Canada Only
California Fuel
If your vehicle is certified to meet California Emission
Standards (see the underhood emission control label),
it is designed to operate on fuels that meet California
specifications. If this fuel is not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp may
turn on (see ªMalfunction Indicator Lampº in the
Index) and your vehicle may fail a smog
-check test.
If this occurs, return to your authorized GM dealer for
diagnosis. If it is determined that the condition is caused
by the type of fuel used, repairs may not be covered by
your warranty.
Additives
Some gasolines that are not reformulated for low
emissions may contain an octane
-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasoline
whether the fuel contains MMT. General Motors
does not recommend the use of such gasolines.
