Press the GAGE INFO button until TIRE PRESSURE
appears in the display. TIRE PRESSURE NORMAL is
displayed when the Check Tire Pressure System
believes your vehicle's tire pressures are normal. If a
potential tire pressure problem is detected, the display
will show TIRE PRESSURE LOW: CHECK TIRES.
If you see the TIRE PRESSURE LOW: CHECK
TIRES message, you should stop as soon as you can
and check all your tires for damage. (If a tire is flat, see
ªIf a Tire Goes Flatº in the Index.) Also check the
tire pressure in all four tires as soon as you can.
See ªInflation
-- Tire Pressureº and ªCheck Tire
Pressure Systemº in the Index. There are times
when you will have to reset (calibrate) the Check
Tire Pressure System. See ªCheck Tire Pressure
Systemº in the Index.

RESET: This button, used along with other buttons,
will reset system functions.

ENG/MET: Use this button to change the display
between English and metric units.

Temperature Button
To adjust the comfort level you want maintained inside
the vehicle, push the TEMP button. If you want a
warmer comfort level, push the up arrow. If you want a
cooler comfort level, push the down arrow. Your
comfort setting is shown in the display. The display will
then return to the outside temperature.
Fan Button
The speed of the blower fan is controlled automatically if
you have the system set for AUTO. Pressing the FAN
button will display and hold the current blower fan setting.
If you want the blower fan to run at a lower speed, push
the bottom of the FAN button. The fan speed will
decrease with every push of the button until the lowest
speed is reached. If you want to increase the fan speed,
push the top of the FAN button. Notice the fan
indicators in the display.
Mode Controls
Press the AIR FLOW button to deliver air through the
floor, middle or windshield outlets. The system will stay
in the selected mode until the AUTO button is pushed.
Use the up and down arrows on the AIR FLOW button
to cycle through the available modes.Automatic Operation
Press the AUTO button when you want the system to
automatically adjust to changes in the temperature inside
the vehicle, the outside temperature and the sun load on
the vehicle. When the system is set for automatic
operation, air will come from the floor, middle or
windshield outlets depending on the temperature inside
the vehicle, the outside temperature and sun load.
Fan speed will vary as the system gets to and maintains
the comfort setting you have selected through the use of
the TEMP button.
To find your comfort setting, start with the system in
AUTO mode and the TEMP button adjusted to 75
F
(24
C), give the vehicle about 20 minutes to stabilize,
and adjust your comfort setting if necessary, by using
the TEMP button. The display will show the comfort
setting for a few seconds and then it will display the
outside temperature. If you want to see your current
automatic fan speed, airflow direction and comfort
setting, press the AUTO button.
In cold weather, the system will delay turning on the
fan, to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and the
outside temperature. Pushing the FAN, AIR FLOW or
FRONT buttons will override this delay, turn off the
AUTO setting and change the fan speed.

Cooling System
When you decide it's safe to lift the hood, here's what
you'll see:
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. 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 recovery tank is boiling,
don't do anything else until it cools down.
When the engine is
cold, the coolant level
should be at or above
the FULL COLD mark
(if the engine is hot,
the coolant level
should be at
FULL HOT).

5-14 How to Add Coolant to the Coolant
Recovery Tank
If you haven't found a problem yet, but the coolant level
isn't at the FULL COLD mark, add a 50/50 mixture of
clean, drinkable water and DEX
-COOL
engine
coolant at the coolant recovery tank. (See ªEngine
Coolantº in the Index for more information.)
CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mixture will. Your vehicle's coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
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 mixture of clean, drinkable water
and DEX
-COOL
coolant.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.

6. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine cooling fans.
7. By this time, the coolant level inside the radiator
filler neck may be lower. If the level is lower, add
more of the proper DEX
-COOL
coolant mixture
through the filler neck until the level reaches the
base of the filler neck.
8. Then replace the
pressure cap. At
any time during
this procedure if
coolant begins to
flow out of the
filler neck, reinstall
the pressure cap.
Be sure the arrows on the pressure cap line up like this.

6-21 How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to use. See ªRecommended
Fluids and Lubricantsº in the Index.
If the fluid level is low, add only enough of the proper
fluid to bring the level into the cross
-hatched area
on the dipstick.
1. Pull out the dipstick.
2. Using a long
-neck funnel, add enough fluid at the
dipstick hole to bring it to the proper level.
It doesn't take much fluid, generally less than one
pint (0.5 L). Don't overfill.
NOTICE:
We recommend you use only fluid labeled
DEXRON
-III, because fluid with that label is
made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON

-III
is not covered by your new vehicle warranty.
3. After adding fluid, recheck the fluid level as
described under ªHow to Check.º
4. When the correct fluid level is obtained, push the
dipstick back in all the way.
Engine Coolant
The cooling system in your vehicle is filled with
DEX
-COOL
engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, if you add only
DEX
-COOL
extended life 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 ªEngine Overheatingº in
the Index.
A 50/50 mixture of clean, drinkable water and
DEX
-COOL
coolant will:

Give freezing protection down to
-34F (-37C).

Give boiling protection up to 265F (129C).

Protect against rust and corrosion.

Help keep the proper engine temperature.

Let the warning lights and gages work as
they should.

yellowblue
6-23
NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged.
The repair cost wouldn't be covered by your
warranty. Too much water in the mixture can
freeze and crack the engine, radiator, heater core
and other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
NOTICE:
If you use the proper coolant, you don't have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
Checking Coolant
The vehicle must be on a
level surface. When your
engine is cold, the coolant
level should be at FULL
COLD or a little higher.
When your engine is warm,
the level should be up
to FULL HOT or a
little higher.
If this ENG COOLANT
LOW
- CHECK LEVEL
message on the DIC comes
on and stays on, it
means you're low on
engine coolant.
