Pressing the AUTO button will display the requested
temperature, fan speed'and
air delivery mode for five
seconds, then change to display the outside air
temperature. Be careful not to put anything over the
sensor located in the middle
of the instrument panel near
the windshield, or over the sensor
in the gnlle above the
radio. These sensors are used by the automatic system to
regulate temperature.
The exterior temperature display sensor is in front
of the
car, near the radiator. This displayed temperature is most
accurate when the vehicle
is moving. During stops, or
while idling, the display shows the previous driving
temperature for best system control.
To avoid blowing cold air in cold weather, the system
will delay turning
on the fan until warm air is available.
The length
of delay depends on outside air temperature,
engine coolant temperature, and time since the engine
was last started. Pushing the
fan button will override this
delay and change the fan to a selected single speed.
If you leave your vehicle, the system will remember the
control setting the next time you start your engine.
Manual Operation
You may also manually adjust the delivery mode or
fan speed.
'!! HEAT: Manually selecting HEAT by cycling
through the
MODE settings will deliver air to the floor
outlets.
+# DEFOG: Manually selecting DEFOG by cycling
through the
MODE settings will deliver air to the floor
and windshield outlets.
12 BI-LEVEL: Manually selecting BI-LEVEL by
cycling through the MODE setting will deliver warm air
to the floor and cooler air to the middle instrument panel outlets.
OFF: Press this button to turn the system off. Fresh air
will continue to flow through the vehicle, and the
system
will try to maintain the previously set
temperature. The outside temperature will show in the
display when the system
is OFF.

‘The coolant level should be at or above the FULL
% COLD mark. If it isn’t, you may have a leak in the
. radiator hoses, heater hoses, radiator, water pump or
somewhere else in the cooling system.
A CAWTION:
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 mn 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.
I NOTICE:
I
Engine damage from running your engine
without coolant isn’t covered by your warranty.
I
If there seems to be no leak, with the engine on, check to
see if the electric engine fans are running. If the engine
is overheating, both fans should be running. If they
aren’t, your vehicle needs service.

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 water (preferably distilled) and DEX-COOL TM
(orange-colored, silicate-free) antifreeze at the coolant
recovery tank. (See “Engine Coolarit” in the Index for
more information.)
Adding only plain water to your cooning system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
CAUTION: (Continued) -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
DEX-COOL TM antifreeze.
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 mix.

How to Add Fluid
Refer to the Maintenance Schedule to determine what
bind of tmhsaxle fluid to use. See 6‘Recomended
Fluids and Lubricants” 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.
Pull out the dipstick.
Using a long-neck funnel, add enough
Md at the
dipstick hole to bring it to the proper level. It doesn’t
take much
fluid, generally less than a pint (0.5 L).
Don’t overfiI2. We recommend you use only fluid
labeled
DEXRON*-III,, because fluid with that label
is made especially for yo& automatic transax18e.
Damage caused
by fluid other than DEXRON’@-III
is not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under “How to Check.”
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 new
DEX-COOL (orange-colored,
silicate-free) engine
coolant.
This coolant is designed to remain in your
vehicle for 5 years or 100,000 miles (166 000 km),
whichever occurs first.
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.
