Flow-Through Ventilation System
W W
Your vehicle’s flow-through ventilation system supplies outside air to the
inside
of your vehicle when it is moving. With the side windows closed, air
will flow into the front air inlet grilles at the base of the windshield, through
the vehicle and out the rear air exhaust valves. Outside air will also enter the
vehicle when the heater or the air conditioning fan is running.
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, turn the blower fan\
to HIGH
for a few moments before driving off. This helps clear the intake ducts
of snow and moisture, and reduces the change
of fogging the inside of
your windows.
0 Keep the air path under the front seats clear of objects. This helps air to
circulate throughout your vehicle.

I You will find air vents
in the center and on
the sides of your
instrument panel.
You can move the
vents to direct the
flow
of air, or close
the vents altogether.
When
you close a
vent, it will increase
the
flow of air corning
out of any vents that
are open.
If your vehicle doesn’t have air conditioning, there is an air vent in the
right-hand kick panel below the instrument panel. The vent has a handle to
open
and close it.

If your vehicle does
conditioning, this is
what your heating system will look like.
I not have air
Fan Lever
The top lever has four positions. To increase the air flow, move the lever
toward
HIGH. To decrease the air flow, move it toward OFF.
Temperature Lever
The left lever lets you select the temperature of the air flowing into your
vehicle. Move the lever up for warmer air. Move the lever down for cooler
air.
Function Lever
The right lever can be moved to five different functions.
DEFROST The setting with the defrost symbol operates the defroster.
Most of the air comes out near
the windshield, with some going to the floor
vents and front side windows. Use this when you get fog or ice on the
windshield.
HTR (Heater): Most of the air comes out near the floor. The rest comes out
from the defroster vents under the windshield and at
the front side windows.
This is best for cold weather.
VENT The air comes out at the vents on your instrument panel.
BLEND (Position 1): With this setting, the heated outside air comes out
between the heater vents and defroster vents. The lever can be positioned
anywhere between to adjust proprotion of air coming through. Adjust the
temperature lever for warmer or cooler air.
BLEND (Position 2): With this setting, the heated outside air comes out
between the vents and heater vents. The lever can be positioned anywhere
between to adjust proprotion of air coming through. Adjust the temperature
lever for warmer
or cooler air.

If your vehicle has air conditioning, your heating/air conditioning system
will look like this.
Before using your
vehicle's air conditioning, open the windows to clear the
vehicle of hot air. Close the windows when using the system.
Fan Lever
The top lever has five positions. To increase the air flow, move the lever
toward
HIGH. To decrease the air flow, move the lever toward OFF.
Temperature Lever
The left lever lets you select the temperature of the air flowing into your
vehicle. Move the lever up for warmer air. Move
the lever down for cooler
air.
Function Lever
The right lever can be moved to four different functions.
DEFROST The setting with the defrost symbol operates the defroster.
Most of the air comes out near the windshield, with some going to the floor
vents and side window defrost vents. Use this when you get fog or ice on
the windshield.
BLEND: With this setting, the heated outside air comes out between the
heater vents and defroster vents, with some air coming through the side
vents. Adjust the temperature lever for warmer or cooler air.
HTR (Heater): Most of the air comes out near the floor. The rest comes out
from the defroster vents under the windshield and at the front side windows.
This
is best for cold weather.

Downloaded from www.Manualslib.com manuals search engine BI-LEV A/C: With this, outside air comes out through the heater floor vent
and the instrument panel vents. If you move your temperature control lever
between cold and hot, cooler air will come out of the upper vents while
warmer air comes out of the floor vent. This setting is useful
in cool weather
with bright sunlight.
NORM A/C: This setting cools the outside air. If you first used MAX A/C,
use NORM A/C as soon as the vehicle has cooled down, so outside air will
be going through your vehicle.
MAX A/C: This cools the air the fastest. Move the other lever all the way to
Cold.
MAX A/C lets in only a little air from the outside. You can use MAX
A/C at first when it's really hot outside and you need to cool off quickly.
When the air conditioning, defrost or Blend is on, you
may notice a slight
increase or decrease
in engine speed, due to compressor operation.
Rear Heater
You may have the
optional rear heater.
The three speed fan
switch is above the
radio. Slide the lever
toward
HI for warmer
air in the rear area.
Move the switch to
OFF to turn the
system off.
Rear Air Conditioning
You may have rear air
conditioning. The rear
air conditioning
switch is located
above the radio at the
top
of the instrument
panel. Slide the lever
toward
HI for cooler
air
in the rear area.
Slide the lever to
OFF
to turn the system off.

Downloaded from www.Manualslib.com manuals search engine If your vehicle has rear air conditioning, setting it on LOW may enhance
front A/C performance by allowing trapped refrigerant in rear lines to
circulate.
The system will only send cooled air if the front system is on. It can still be
used to recirculate air, even if the front system is off.
Before using the rear air conditioning, open the windows to clear the vehicle
of hot air. Close the windows when using the system.
Rear Window Defogger
If your vehicle has this option the rear window will have lines running
across the glass. These lines heat your window.
For best results, clear the window
of as much snow or ice as possible before
using the rear window defogger.
To turn on the rear
window defogger, find
the switch marked
REAR DEFOG on
your instrument panel
to the left
of the
steering column. Press
the top of this switch
until the light in the
switch comes on, then
release it.
The rear window defogger will only work when the ignition switch is in \
the
RUN position.
You can turn the defogger off at any time by pressing the bottom of the
switch. The defogger will shut itself off after several minutes
so that the
glass does not get too hot. If
the window still isn’t clear, turn the defogger
on again.
I NOTICE:
Scraping the inside of your rear window could cut and damage
the defogger. Your warranty would not cover this damage. And
don’t put decals there, you might have to scrape them
off.

If you use the optional engine coolant heater before starting your engine,
your heating system will produce warmer air faster to heat the passenger
compartment in cold weather. See “Engine Coolant Heater” in the Index.
Audio Systems
Your Delco@ audio system has been designed to operate easily and give
years
of listening pleasure. But you will get the most enjoyment out of it, if
you acquaint yourself
with it first. Find out what your Delco@ system can
do and how to operate all its controls, to be sure you’re getting the most out
of
the advanced engineering that went into it.
Be aware that hearing damage from loud noise is almost undetectable until
it is too late. Your hearing can adapt to higher volumes of sound. Sound that
seems normal can be loud and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to a safe sound level before your
hearing adapts to it.
To help avoid hearing loss or damage:
0 Adjust the volume control to the lowest setting.
Increase volume slowly until you hear comfortably and clearly.
FM Stereo
FM stereo will give you the best sound. But FM signals will reach only
about
10 to 40 miles (16 to 65 km). Tall buildings or hills can interfere with
FM signals, causing the sound to come and go.
The range for most AM stations is greater than for FM, especially at night.
The longer range, however, can cause stations to interfere
with each other.
AM can pick up noise from things like storms and power lines. Try reducing
the treble to reduce this noise
if you ever get it.
AM Stereo
This means the Delco@ system can receive C-QUAM@ stereo broadcasts.
Many AM stations around the country use C-QUAM@ to produce stereo,
though some do not. (C-QUAM@ is
a registered trademark of Motorola,
Inc.) If your Delco@ system can get C-QUAM@, your
“STEREO” light will
come on
when you’re receiving it.
