(Recirculation): This button is used to recirculate
much of the air inside your vehicle. This setting is not
available in defogger or defroster. Operating the system
in recirculation may cause the windows to fog up when
the weather is cold and damp. To clear the fog, use the
defog or defrost modes and increase the fan speed. To
avoid refogging of the windows, use the outside air
mode.
(Outside Air): This button is used to bring
outside air into the vehicle.
Air Conditioning
On very hot days, open the windows long enough
to let hot inside air escape. This reduces the time
the compressor has to run, which should help with
fuel economy.
For quick cool
-down on very hot days, use the
vent outlets, recirculation with the temperature knob
turned all the way to the blue area, the air conditioner
on, and the fan on a high setting. If this setting is used
for long periods of time, the air in your vehicle may
become too dry.For normal cooling on hot days, use the vent outlets
with the temperature knob turned to the blue area. With
the A/C button and the outside air button pressed in, the
system will bring in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough. To
remedy this, you can use bi
-level with the temperature
knob in the middle with the A/C button and the outside
air button pressed. The system will bring in outside air
and direct it to your upper body, while sending slightly
warmed air to your lower body. You may notice the
temperature difference more at some times than others.
Heating
On cold days turn the fan on and use floor and the
outside air button pressed in with the temperature knob
turned all the way to the red area. The system will bring
in outside air, heat it and send it to the floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside (0
F (
-18
C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See ªEngine Coolant
Heaterº in the Index.

For normal cooling on hot days, use the vent outlets and
outside air with the air conditioning. The system will
bring in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
To remedy this, you can use bi

direct it to your upper body, while sending slightly
warmed air to your lower body. You may notice this
temperature difference more at some times than others.
Heating
On cold days use the floor mode and the temperature
turned toward red, with a high fan setting. The system
will bring in outside air, heat it and send it to the
floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside (0
F (

C) or lower). An engine
coolant heater warms the coolant your engine and
heating system use to provide heat. See ªEngine
Coolant Heaterº in the Index.Ventilation
For mild outside temperatures when little heating or
cooling is needed, use the vent outlets, a fan setting,
ECON and outside air to direct outside air through your
vehicle. Your vehicle also has the flow
-through
ventilation system described later in this section.
Defogging and Defrosting
Your system has two settings for clearing the front
and side windows. To defrost the windows quickly,
use the defrost button. To warm passengers while
keeping the windows clean, select defog by pressing
the MODE button.

Cooling System
When you decide it's safe to lift the hood, here's what
you'll see:
A. Coolant Surge Tank
B. Electric Engine Cooling Fans
CAUTION:
An electric engine cooling 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.
If the coolant inside the coolant surge tank is boiling,
don't do anything else until it cools down. The vehicle
should be parked on a level surface.

5-14
The coolant level should beat or above the FULL COLD
mark on the coolant surge tank. If it isn't, you may have
a leak at the pressure cap or in the radiator hoses, heater
hoses, radiator, water pump or somewhere else in the
cooling system.
CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don't touch them. If you
do, you can be burned.
Don't run the engine if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
If there seems to be no leak, with the engine on, check to
see if the electric engine cooling fans are running. If the
engine is overheating, both fans should be running. If
they aren't, your vehicle needs service.

5-16 How to Add Coolant to the Coolant
Surge Tank
If you haven't found a problem yet, check to see if
coolant is visible in the surge tank. If coolant is visible
but the coolant level isn't at the FULL COLD mark, add
a 50/50 mixture of clean, drinkable water and
DEX
-COOL
coolant at the coolant surge tank, but be
sure the cooling system, including the coolant surge tank
pressure cap, is cool before you do it. See ªEngine
Coolantº in the Index for more information.
If no coolant is visible in the surge tank, add coolant
as follows:
CAUTION:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They are
under pressure, and if you turn the coolant surge
tank pressure cap
-- even a little -- they can come
out at high speed. Never turn the cap when the
cooling system, including the coolant surge tank
pressure cap, is hot. Wait for the cooling system
and coolant surge tank pressure cap to cool if you
ever have to turn the pressure cap.

5-18
1. Park the vehicle
on a level surface.
You can remove
the coolant surge
tank pressure cap
when the cooling
system, including
the coolant surge
tank pressure
cap and upper
radiator hose, is
no longer hot.
Turn the pressure cap slowly counterclockwise (left)
about one
-quarter turn and then stop.
If you hear a hiss, wait for that to stop. A hiss means
there is still some pressure left.
2. Then keep turning the pressure cap slowly, and
remove it.3. Then fill the coolant surge tank with the proper
mixture, to the FULL COLD mark.

5-19
4. With the coolant surge tank pressure cap off, start the
engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the engine
cooling fans.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower, add
more of the proper mixture to the coolant surge tank
until the level reaches the FULL COLD mark.
5. Then replace the pressure cap. Be sure the pressure
cap is hand
-tight and fully seated.
If a Tire Goes Flat
It's unusual for a tire to ªblow outº while you're driving,
especially if you maintain your tires properly. If air goes
out of a tire, it's much more likely to leak out slowly.
But if you should ever have a ªblowout,º here are a
few tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you'd use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop
-- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely.

6-26 Checking Coolant
The coolant surge tank is located in the engine
compartment toward the rear of the engine on the
passengers' side of the vehicle. See ªEngine
Compartment Overviewº in the Index for more
information on location.
CAUTION:
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
Never turn the surge tank pressure cap
-- even a
little
-- when the engine and radiator are hot.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the FULL
COLD mark.
If the low coolant warning
light comes on and stays on,
it means you're low on
engine coolant.
