2004 CHEVROLET EXPRESS CARGO VAN air condition

This switch should only be turned to AIR BAG OFF if
the person in the right front passenger’s position is
a member of a passenger risk group identied by the
national government as follows:
Infant.An infant (less than 1 year old) must
ride in the front seat because:

my vehicle has no rear seat;
my vehicle has a rear seat too small to
accommodate a rear-facing infant seat; or
the infant has a medical condition which, according
to the infant’s physician, makes it necessary for the
infant to ride in the front seat so that the driver
can constantly monitor the child’s condition.
Child age 1 to 12.A child age 1 to 12 must
ride in the front seat because:

my vehicle has no rear seat;
although children ages 1 to 12 ride in the rear
seat(s) whenever possible, children ages 1 to
12 sometimes must ride in the front because no
space is available in the rear seat(s) of my vehicle;
or
the child has a medical condition which, according
to the child’s physician, makes it necessary for the
child to ride in the front seat so that the driver
can constantly monitor the child’s condition.
Medical Condition.A passenger has a
medical condition which, according to his or
her physician:

causes the passenger air bag to pose a special risk
for the passenger; and
makes the potential harm from the passenger air
bag in a crash greater than the potential harm
from turning off the air bag and allowing the
passenger, even if belted, to hit the dashboard or
windshield in a crash.
{CAUTION:
If the right front passenger’s air bag is turned
off for a person who isn’t in a risk group
identied by the national government, that
person won’t have the extra protection of an
air bag. In a crash, the air bag wouldn’t be able
to inate and help protect the person sitting
there. Don’t turn off the passenger’s air bag
unless the person sitting there is in a risk
group. See “Air Bag Off Switch” in the Index.

Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Turn the right knob clockwise or counterclockwise to
direct the airow inside of your vehicle.
To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs about half of the air
to the instrument panel outlets, then directs most of
the remaining air to the oor outlets. Some air may be
directed toward the windshield.
6(Floor):This mode directs most of the air to the
oor outlets with some air directed to the outboard
outlets (for the side windows) and some air directed to
the windshield.
The right knob can also be used to select the defrost
mode. Information on defogging and defrosting can
be found later in this section.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
(Temperature Control):Turn the center knob
clockwise or counterclockwise to increase or decrease
the temperature inside your vehicle.
If your vehicle has air conditioning, your heating/air
conditioning controls will look like this:
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
3-19

A/C (Air Conditioning):This setting will begin to cool
and dehumidify the air inside of your vehicle.
MAX A/C (Maximum Air Conditioning):Turn the right
knob to MAX A/C for maximum cooling. This setting
cools the air the fastest, by recirculating the inside air.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control is used properly.
There are two modes to clear fog or frost from your
windshield and side windows.
Use the defog mode to clear the windows of fog or
moisture and warm the passengers. Use the defrost
mode to remove fog or frost from the windshield more
quickly. For best results, clear all snow and ice from the
windshield before defrosting.
Turn the knob on the right of the climate control panel
to select the defog or defrost mode.
-(Blend):With this setting, the outside air comes out
of both the oor and defroster outlets. Adjust the
temperature knob for warmer or cooler air. The air
conditioning compressor may operate in this setting to
dehumidify the air.
1(Defrost):This setting operates the defroster. Most
of the air comes out near the windshield, with some
going to the oor outlets and front side windows. The air
conditioning compressor may operate in this setting to
dehumidify the air.
The blend setting is useful for cold weather with a large
number of passengers or very humid conditions to
help keep the windshield clear. Use defrost to remove
fog or ice from the windshield quickly in extremely
cold conditions. The temperature knob should be in the
red area and the fan control toward high. Do not
drive the vehicle until all the windows are clear.
3-20

Rear Heating System
Your vehicle may have a rear heating system that allows
you to adjust the amount of air owing into the rear of the
vehicle, from the front-seating area. This feature works
with the main climate-control system in your vehicle.
AUX (Auxiliary Heating System):The thumbwheel for
this system is located to the right of the audio system.
9(Fan):Turn the thumbwheel up or down to increase
or decrease the amount of heated air sent to the
rear-seating area.
9(Off):Turn the thumbwheel to this position to turn
off the rear heating system.
Rear Air Conditioning and Heating
System
Your vehicle may have a rear heating and
air-conditioning system. This system regulates the
temperature, the fan speed and the air delivery for the
rear-seat passengers only. It also works with the
main climate-control system in your vehicle.
Use this control panel when you would like to maintain
a separate temperature setting. Adjust the direction
of the airow or adjust the fan speed for the rear-seat
passenger(s).
Front Climate-Control Panel
3-22

If your vehicle has a 135 inch wheelbase, a rear control
panel for this system is located in the second row
behind the driver in the rear of your vehicle. A rear-seat
passenger can use this control panel to personally
adjust the temperature, the direction of the airow and
the fan speed for the rear-seating area.
The fan knob located on the front climate control panel
must be turned to REAR CNTL to allow a rear-seat
passenger to use the control panel in the rear-seating
area. Performing this action disables the front control
panel. To return control to this panel, move the fan knob
out of REAR CNTL.
Turn the center knob clockwise or counterclockwise
to change the direction of the airow in the
rear-seating area.To change the current mode, select one of the following:
D(Vent):Use this mode to direct air to the upper
outlets, with a little air directed to the oor outlets.
2(Floor):Use this mode to direct most of the air to
the oor outlets.
9(Fan):Turn the left knob clockwise or
counterclockwise to HIGH, MED (Medium) or LOW to
increase or decrease the fan speed in the rear-seating
area. Turn the knob to OFF to turn off the fan.
(Temperature Control):To increase or decrease the
temperature for the rear of the vehicle, turn the right
knob located on the climate-control panel.
The air-conditioning system on the main climate-control
panel must be turned on to direct cooled air to the
rear of the vehicle. If it is not on, then the temperature
in the rear of the vehicle will remain at cabin
temperature.
Be sure to keep the area under the front seats clear of
any objects so that the air inside of your vehicle can
circulate effectively.
For information on how to use the main climate-control
system, seeClimate Control System on page 3-19listed
previously in this section. For information on ventilation,
see “Outlet Adjustment” earlier in this section. Rear Climate-Control Panel

Charging System Light
This light should come on
briey when you turn on
the ignition, before starting
the engine, as a check
to show you it is working.
After the engine starts, the light should go out. If it stays
on or comes on while you are driving, you may have
a problem with your charging system. It could indicate a
problem with the generator drive belt, or some other
charging system problem. Have it checked right away.
Driving while this light is on could drain your battery.
If you must drive a short distance with this light
on, it helps to turn off all your accessories, such as the
radio and air conditioner.
Voltmeter Gage
When your engine is not
running, but the ignition is
on (in the RUN position),
this gage shows your
battery’s state of charge in
DC volts.
When the engine is running, the gage shows the
condition of the charging system. Readings between the
low and high warning zones indicate the normal
operating range.
Readings in the low warning zone may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since the
charging system is not able to provide full power
at engine idle. As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.
