Comfort Controls
With this system, you can control the heating and
ventilation in your Geo.
If you have the air conditioning
option, you can also control cooling.
Your vehicle also has the flow-through ventilation
system described later in this section.

Air Conditioner Controls (Option)
The air conditioning system
uses the same controls as
described previously. The
function
of each lever is
explained under “Climate
Control System” in this
part. The incoming air is
cooled and dehumidified
instead of being heated.
Push the
A/C button to change your comfort control
system from heating to air conditioning.
A light will
come
on when the air conditioning is on. The A/C
button can also control the humidity in your vehicle.
The air conditioner works best if you keep your
windows closed. On very hot days, open the windows
just long enough for the hot air to escape.
For normal cooling, push the
A/C button and move the
air intake lever to CIRCULATE. For faster cooling,
move the lever to RECIRCULATE. Then move the
airflow lever to VENT, the temperature control lever
toward the left and the fan control lever toward the
fan symbol.
On days when
it is raining or the humidity is high,
follow these dehumidifying steps to help clean windows
that are cloudy with moisture. Push the A/C button.
Move the air intake lever to CIRCULATE. Move the
airflow lever to DEFROST and
the fan control lever
toward the fan symbol. Adjust
the temperature control
lever to
a comfortable setting.

2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other.
If they are, it could cause a ground
connection you don’t want. You wouldn’t be able
to
start your Geo, and the bad grounding could damage
the electrical systems.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter. Turn
off all lamps that aren’t needed as well
as radios. This will avoid sparks and help save both
batteries.
In addition, it could save your radio!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
4. Open the hoods and locate the batteries. Find the
positive
+ and negative (-) terminals on each battery.
I A CAUTION:
I
An electric fan can start up even when the
is not running and can injure you. Keep hands,
clothing and
tools away from any underhood
electric fan.
-
CAUTION:
If your vehicle has air conditioning, the auxiliary
electric fan under the hood can start
up even
when the engine
is not running and can injure
you. Keep hands, clothing and tools away from
any underhood electric fan.
