2002 PONTIAC GRAND AM air condition

2-58 Charging System Indicator Light
The charging system
indicator light will come on
when you turn on the
ignition, but the engine is
not running, as a check to
show you it is working.
When the engine is running, the light should go out.
If it stays on, or comes on while you are driving and you
hear a chime, you may have a problem with the
electrical charging system. It could indicate that you
have a loose generator drive belt or another electrical
problem. Have it checked right away. Driving while
this light is on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.
Up-Shift Light (Manual Transaxle)
(If Equipped)
This light comes on when
you need to shift to the next
higher gear. See ªManual
Transaxleº in the Index.

2-64
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.
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.

Comfort Controls
With this system, 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 with
Air Conditioning
Fan Knob
The left knob regulates the fan speed. To select the force
of air you want, turn the knob. The fan is always
running unless the fan knob is moved to OFF.Temperature Knob
The center knob regulates the temperature of the air
coming through the system.
Mode Knob
The right knob changes the functions of your system.
MAX (Maximum): Use this mode for
maximum cooling. This setting recirculates much of
the air inside your vehicle. It maximizes your air
conditioner's performance and your vehicle's fuel
economy. The air conditioning compressor will run
automatically in this position when it is needed to
help dry the air in the vehicle.
(Vent): In this mode most of the airflow comes
through the instrument panel outlets. A small amount of
air comes through the floor vents. Set the center knob to
the desired temperature for comfort.
(Bi-Level): In this position the airflow
comes through the instrument panel outlets and
through the floor outlets. Set the center knob to the
desired temperature.

3-3
(Floor): In this mode most of the airflow comes
through the floor outlets. The rest of the air comes
through the windshield and side window vents. Set the
center knob to the desired temperature for comfort.
(Defog): This mode divides the airflow between
the floor outlets and the windshield defroster vent. The
air conditioning compressor will run automatically in
this mode when it is needed to help dry the air in
the vehicle.
(Front Defroster): This mode directs most of the
airflow through the windshield defroster vent. Some of
the air goes to the floor outlets. The air conditioning
compressor will run automatically in this mode when it
is needed to help dry the air in the vehicle.
Mode Button
A/C (Air Conditioning): Press A/C to operate the
air conditioning. The indicator light above the button
will glow when the button is pressed to indicate that the
air conditioning system has been turned on. The fan
knob must be set to a speed for the air conditioning
to operate.
Air Conditioning
The air conditioner and heater work best if you keep
your windows closed while using them. Your vehicle
also has the flow
-through ventilation system described
later in this section.
For normal cooling on hot days, use the vent mode with
the temperature knob in the blue area and the A/C
indicator light glowing. The system will bring in outside
air and cool it.
On very hot days, begin by opening 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.
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 mode with the temperature knob in
the middle and the A/C indicator light glowing. The
system will bring in outside air and direct slightly
warmer air to your lower body.

3-4 Heating
On cold days, use floor mode 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 outlets.
Your vehicle has heat ducts that are directed toward
the rear seat. Keep the area under the front seats
clear of objects 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 in your engine and heating
system that is used to provide heat. See ªEngine Coolant
Heaterº in the Index.
Defogging and Defrosting Windows
Your system has two modes for clearing the front and
side windows. For each setting, adjust the temperature
control as desired.
To defrost the front window quickly, turn the
temperature knob all the way in the red area. Use front
defroster and adjust the fan to the highest speed. To
warm passengers while keeping the front window clean,
use defog.
Your vehicle is equipped with side window defogger
vents. The side window defogger vents are located on
the outside of the side instrument panel vents. To defrost
the side windows, turn the temperature knob all the way
in the red area. Use floor mode and adjust the fan to the
highest speed.
To defog the side windows while using air conditioning,
use bi
-level mode and adjust the fan to the highest speed
and press the A/C button so that the indicator light is
glowing. For added airflow to the side windows, aim
the side vents toward the windows and close the
center vents.

3-5 Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
The button is located
near the center of the
instrument panel.
Press the defogger button. The indicator light above the
button will glow. The rear window defogger will turn
itself off after about 10 minutes after the first time the
button is pressed, and after five minutes each additional
time the button is pressed. You can turn the defogger off
by pressing the button again or turning off the ignition.
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.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use the vent mode to direct outside
air through your vehicle. Your vehicle also has the
flow
-through ventilation system which supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
is running. Recirculation of the air is automatic in
MAX A/C.

5-10 If No Steam Is Coming From Your Engine
An overheat warning, along with a low coolant light,
can indicate a serious problem. See ªLow Coolant
Lightº in the Index.
If you get an engine overheat warning with no low
coolant light, 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) for
an automatic transaxle, or for a manual transaxle
shift to FIFTH (5) or FOURTH (4).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.
You may decide not to lift the hood but to get service
help right away.
