2002 CHEVROLET BLAZER light

3-3
A/C (Air Conditioning): This setting cools and
dehumidifies the air entering your vehicle and directs
most of the air through the instrument panel vents
and a small amount through the floor ducts.
(Bi-Level Air Conditioning): This setting cools
and dehumidifies the air entering your vehicle and
directs it through the floor ducts as well as the
instrument panel outlets.
(Vent): This setting directs most of the air through
the instrument panel outlets and a small amount through
the floor outlets.
(Floor): This setting directs most of the air
through the floor ducts and some air through the
windshield defroster outlets.
(Blend): Airflow is divided equally between the
floor ducts and the windshield defroster outlets.
(Defrost): This setting directs most air through
the windshield defroster outlets and some through the
floor ducts.
Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
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, use MAX A/C
with the temperature knob turned to the left. This setting
should be used to keep odors and/or dust from entering
the vehicle. For normal cooling on hot days, use A/C
with the temperature knob turned to the left.
On cool but sunny days, use Bi
-Level A/C to deliver
warmer air to the floor and cooler air to the instrument
panel outlets.
When the air conditioner is on, you may sometimes
notice slight changes in your vehicle's engine speed and
power. This is normal because the system is designed
to cycle the compressor on and off to keep the
desired temperature.

3-4 Heating
The heater works best if you keep your windows closed
while using it. On cold days, use floor mode with the
temperature knob turned clockwise. Blend mode is
useful in cool weather when you have fog or ice on the
windshield or side windows.
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 ªEngine Coolant Heaterº in the Index.
Defogging and Defrosting
On cool, humid days, use blend mode to keep the
windshield and side windows clear.
Use defrost mode to remove fog or ice from the
windshield quickly in extreme humid or cold conditions.
Turn the temperature knob clockwise and move the fan
knob toward high.
Rear Window Defogger (If Equipped)
If your vehicle has this
feature, the rear window
will have lines that warm
the glass.
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 button
marked REAR with the defog symbol on the lower right
corner of your climate control system. Press the button
until the light in the button comes on, then release it. It
will only work if the ignition switch is turned to RUN.
Pressing the REAR button on your climate control
system will also activate your heated outside mirrors
(if equipped). This will help to keep ice and snow from
collecting on your mirror surfaces.

RECALL: Pressing this button will display the station
being played or it will display the clock. Clock display

SCV (Speed
-Compensated Volume): With SCV, your
audio system adjusts automatically to make up for road
and wind noise as you drive. Set the volume at the
desired level. Turn the control ring behind the upper
knob clockwise to adjust the SCV. Each notch on the
control ring allows for more volume compensation at
faster vehicle speeds. Then, as you drive, SCV
automatically increases the volume, as necessary, to
overcome noise at any speed. The volume level should
always sound the same to you as you drive. If you don't
want to use SCV, turn the control all the way down.
