Air Conditioner Controls
The air conditioning system uses the
same controls as the heating system. The
function of each lever is explained under
“Heater Controls” in this part. The
incoming air is cooled and dehumidified
instead of being heated.
A/C: Push this 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.
Cooling
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.

Your Driving and the Road
they are not. It’s important to check
occasionally to be sure the trailer bulbs
are still working.
Driving on Grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes
so much
that they would get hot and no longer
work well.
On a long uphill grade, shift down and
reduce your speed
to around 45 mph
(70 km/h) to reduce the possibility of
engine and transmission overheating.
If your trailer weighs more than 1,000
pounds
(450 kg), and you have a manual
transmission with fifth gear, it’s better
not to use fifth gear. Just drive
in fourth
gear (or, as you need to, a lower gear).
Parking on Hills
You really should not park your vehicle,
with a trailer attached, on a hill. If
something goes wrong, your rig could
start to move. People can be injured,
and both your vehicle and the trailer can
be damaged.
But
if you ever have to park your rig on
a hill, here’s how to do
it:
1. Apply your regular brakes, but don’t shift into

How to Add Coolant to the Coolant
Recovery
Tank
If you haven’t found a problem yet, but
the coolant level isn’t at or above
FULL, add a 50/50 mixture of clean
water
(preferably distilled) and the
proper antifreeze at the coolant recovery
tank. (See “Engine Coolant”
in the
Index for more information about the
proper coolant mix.)
A Adding only plain water to
L your cooling system can be
dangerous. Plain water, or some
other liquid, like alcohol, can boil
before the proper coolant mix will.
Your vehicle’s coolant warning
system is set for the proper coolant
mix. With plain water, or the
wrong mix, your engine could get
too hot but you wouldn’t get the
overheat warning. Your engine
could catch fire and you or others
could be burned. Use a 50/50 mix
of clean water and a proper
antifreeze.

How to Check Lubricant:
If the level is below the bottom of the
filler plug hole, you’ll need to add some
lubricant.
If the differential is at operating
temperature (warm), add enough
lubricant to raise the level to the bottom
of the filler plug hole.
If the differential
is cold, add enough
lubricant to raise the level to
1/2 inch
(12 mm) below the filler plug hole.
What to Use:
Refer to the Maintenance Schedule to
determine what kind of lubricant to use.
See “Recommended Fluids and
Lubricants” in the Index.
Engine Coolant
The following explains your cooling
system and how to add coolant when it
is low. If you have a problem with
engine overheating, see “Engine
Overheating” in the Index.
The proper coolant for your Geo will:
Give freezing protection down to

Protect against rust and corrosion.

What to Use:
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze or approved recycled coolant
that meets “GM Specification 6038M,”
which won’t damage aluminum parts.
Also use GM Engine Coolant
Supplement (sealer) with a complete
coolant change. If you use these, you
don’t need to add anything else.

Radiator Pressure Cap
IVU I IIJt
Your radiator pressure cap is a 13
- i (90 kPa) pressure-type cap and
must be tightly installed to prevent
coolant
loss and possible engine
damage from overheating. Be sure
the arrows on the cap line up with
the overflow tube on the radiato
filler neck.
I
When you replace your radiator pressure
cap, an
AC* cap is recommended.
Thermostat
Engine coolant temperature is controlled
by a thermostat in the engine coolant
system. The thermostat stops the flow
of
coolant through the radiator until the
coolant reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.
Power Steering Fluid
How to Check Power Steering Fluid:
Unscrew the cap and wipe the dipstick
with a clean rag. Replace the cap and
completely tighten it. Then remove the
cap again and look at the fluid level on
the dipstick.
