2002 CHEVROLET VENTURE air condition

2-109
NOTICE:
Modifications made to the engine, transaxle,
exhaust, intake 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 or
CHECK ENGINE 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.

2-110
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.

2-112
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 full.

It takes a little 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 empty when the ignition
is turned off.
Message Center
The message center is located in the instrument
panel cluster. It gives you important safety and
maintenance facts.
Charging System Indicator Message
The charging system
battery symbol will come
on in the message center
when you turn on the
ignition as a check to
show you it is working.
It will remain on as long as the engine is not running. It
should go out once the engine is running. If it stays on,
or comes on while you are driving, you may have a
problem with the charging system. It could indicate that
you have problems with a generator drive belt, or
another electrical problem. Have it checked right away.
Driving while this indicator appears in the message
center could drain your battery.
If you must drive a short distance with the message on,
be certain to turn off all your accessories, such as the
radio and air conditioner.

2-124 How the System Works
If the rear park aid disable switch is not on, the rear
parking assist turns on automatically when the shift
lever is moved into REVERSE (R) and the vehicle
speed is less than 3 mph (5 km/h). When the system
turns on, the three lights on the display will illuminate
for 1.5 seconds to let you know that the system is
working. Rear parking assist senses how close your
vehicle is to an object. The distance is determined by the
four ultrasonic sensors located on the rear bumper.
When shifting into REVERSE (R) and an object is
detected, one of the following will occur:

Amber/amber/red lights flashing and
continuous chime 1 ft. (0.3 m). . . . . . . . . . . . . . . . .

Amber/amber/red lights and
continuous chime 20 in. (0.5 m). . . . . . . . . . . . . . . .

Amber/amber lights 40 in. (1.0 m). . . . . . . . . . . . . .

Amber light 5 ft. (1.5 m). . . . . . . . . . . . . . . . . . . . .
A chime will sound the first time an object is detected,
if the object is between 20 inches (0.5 cm) and
5 feet (1.5 m) away.
Rear parking assist can detect objects 3 inches (7.6 cm)
and wider, and at least 10 inches (25.4 cm) tall, but it
cannot detect objects that are above liftgate level. In
order for the rear sensors to recognize an object, it must
be within operating range.If the rear parking assist system is not functioning
properly, the display will flash red, indicating that there is
a problem, unless the disable switch is on. The light will
also flash red when the vehicle is shifting into
REVERSE (R), if a trailer was attached to your vehicle,
or if a bicycle or an object was on the back of, or hanging
out of your liftgate during your last drive cycle. The light
will continue to flash whenever in REVERSE (R) until
your vehicle is driven forward at least 15 mph (25 km/h)
without any obstructions behind the vehicle.
It will also flash red if the ultrasonic sensors are not kept
clean. So be sure to keep your rear bumper free of mud,
dirt, snow, ice and slush or the system may not work
properly. If after cleaning the rear bumper and driving
forward at least 15 mph (25 km/h), the display continues
to flash red, see your dealer.
It may also flash red if your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph (5 km/h).
Other conditions that may affect system performance
include things like the vibrations from a jackhammer or
the compression of air brakes on a very large truck.
As always, drivers should use care when backing up a
vehicle. Always look behind you, being sure to check
for other vehicles, obstructions and blind spots.
For cleaning instructions, see ªCleaning Your Vehicleº
in the Index.

Comfort Controls
This section tells you how to make your air system work
for you.
With this system, you can control the heating, cooling
and ventilation in your vehicle. Your vehicle also has
a flow
-through ventilation system described later in
this section.
Fan Knob
The left knob is the fan knob and is used to select the
force of air you want. Turn the knob clockwise to
increase fan speed and counterclockwise to decrease fan
speed. The fan must be turned on for the air
conditioning compressor to operate.Temperature Knob
The center knob controls the temperature of the air
coming through the system. Turn it clockwise toward
the red area for warmer air. Turn it counterclockwise
toward the blue area for cooler air.
Mode Knob
The right knob is used to select the direction of the air
flowing into the vehicle.
(Vent): This setting directs air through the
instrument panel outlets.
(Bi-Level): This setting directs air into your
vehicle in two ways. Cooler air is directed toward your
upper body through the instrument panel outlets, while
warmer air is directed through the floor ducts.
(Floor): This setting brings in most of the air
through the floor ducts. This setting is also used to send
air to the rear of the vehicle. Keep the area under the
front seats free of objects that could obstruct airflow to
the rear of the vehicle.

3-3
(Defog): This setting directs air to the windshield
and through the floor ducts. This mode is useful during
cold or inclement weather because of your vehicle's
larger windshield area.
(Defrost): This setting directs most of the air to the
windshield and side window vents.
Mode Buttons
(Outside Air): Press this button to send outside
air into your vehicle. The light in the button will glow
when outside air is in use. Using this setting while trying
to defrost or defog the windows will help clear the vents
of moisture. While floor, defog or defrost mode is
selected, the system will automatically go to outside
air mode.
(Recirculation): Press this button to limit the
amount of outside air entering your vehicle. The light in
the button will glow when outside air is in use. You may
use this setting to limit odors entering your vehicle.
Operating the Heating/Ventilation/Air Conditioning
(HVAC) system in the recirculation mode may cause
fogging of the vehicle's windows when the weather iscold and damp. To clear the fog, switch the HVAC
system to either the defog or defrost mode and increase
the fan speed. To avoid re
-fogging of the windows,
operate the HVAC system in the outside air mode.
A/C (Air Conditioning): Press this button to turn
the air conditioning compressor on and off. The light in
the button will glow when the air conditioning is in use.
Air Conditioning
On very hot days, your vehicle will cool down more
quickly and economically if you open the windows long
enough to let hot, inside air escape. For all settings,
adjust the temperature control knob and fan speed
as desired.
To get maximum cooling or a quick cool
-down on
very hot days, press the A/C and recirculation buttons
and turn the temperature knob counterclockwise toward
the blue area. Adjust the mode knob to direct the air to
the desired location. This setting should not be used for
long periods of time because the air may become too
cold and dry. Push the A/C button again the to turn off
the air conditioning.

3-4
When the air conditioner compressor is on, you may
sometimes notice slight changes in your vehicle's engine
performance and power. This is normal. The system is
designed to help fuel economy while it maintains the
desired cooling level.
The air conditioner removes moisture from the air, so
you may sometimes notice water dripping from under
your vehicle's engine compartment when it is idling or
after it has been turned off. This is normal.
Heating
Turn the temperature knob clockwise toward the red
area to warm the air.
In the floor mode, outside air will be brought in and sent
through the floor outlets. The heater works best if you
keep your windows closed while using it.
The bi
-level setting is designed for use on sunny days
when the air is only moderately warm or cool. On days
like these, the sun may adequately warm your upper
body, but your lower body may not be warm enough.
For the best results, turn the temperature control knob to
the middle position, and then adjust it for comfort.Your vehicle has a computer controlled transaxle
designed to warm up the engine faster when the outside
temperature is 35
F (2
C) or colder. You may notice
that the transaxle will shift at a higher vehicle speed
until the engine is warmed up. This is a normal
condition designed to provide heat to the passenger
compartment and defrost the windows more quickly.
If you have the optional engine coolant heater and use it
during cold weather, 0
F (
-18
C) or lower, your heating
system will provide heat more quickly because the
engine coolant is already warmed. See ªEngine Coolant
Heaterº in the Index.
Defogging and Defrosting
To rapidly defrost the windshield, turn the temperature
control knob all the way clockwise to the red area and
turn the mode knob to defrost. Adjust the fan to the
highest speed.
To keep the windshield clear and bring in heated air
through the floor ducts, turn the mode knob to defog.
When the temperature outside is above freezing, the air
conditioner compressor will run in these settings to help
remove moisture from the air.
