OFF position
The OFF position shuts off the air supply to
all outlets and stops all fan operations. Use
the OFF position to prevent cold air from
entering the passenger compartment under
cold outside conditions before the engine is
warmed up.
MAX A/C Position
Interior air is recirculated inside the vehicle.
Turn the air control dial to the MAX A/C
position when driving on a dusty road or
to help keep out traffic fumes.
Turn the air control dial to the MAX A/C
position for improved air conditioner perfor-
mance under high temperature and high hu-
midity conditions.
CAUTION
Do not use MAX A/C for long periods as
it may cause the interior air to become
stale and the windows to fog up.
Air conditioner button
Start the engine, move the fan control dial to
the desired (one to four) position, select an
air control position and push the air condi-tioner button to turn on the air conditioner.
The indicator light comes on when the air
conditioner is operating. To stop the air con-
ditioner, push the button again; the indicator
light goes off.
The air conditioner cooling function op-
erates only when the engine is running.
HEATER OPERATION
Heating
This mode is used to direct most of the hot
air to the front and rear floor outlets. Rear
passenger heat is provided by the front
system through floor outlets located under
both front seats.
1. Move the air control dial to the
po-
sition.
2. Turn the fan control dial to select speed.
3. Move the temperature control dial to the
desired position.

Operating Tips
Clear snow and ice from the wiper blades
and air inlet in front of the windshield.
This improves defrosting/defogging op-
eration.
Bi-level heating/cooling
The bi-level mode directs air to the side and
center vents and to the front and rear floor
outlets.
Bi-level is also a cooling mode when high
sun load conditions are present with cool
temperatures.
With the A/C system in operation, this mode
can be used to cool the passenger's or
driver's feet under high temperature condi-
tions.
With the A/C system in operation under high
temperature conditions, improved cooling
can be obtained by moving the air control
dial to the MAX A/C position.
1. Move the air control dial to the
po-
sition.
2. Turn the fan control dial to the desired
position.3. Move the temperature control dial to the
desired position.

windshield. This mode directs air to the
defroster and the front and rear floor outlets.
Rear passenger heat is provided by the
front system through floor outlets located
under both front seats.
1. Move the air control dial to the
po-
sition.
2. Turn the fan control dial to the desired
position.
3. Move the temperature control dial to the
desired position.
When the
position is selected, the
air conditioner automatically turns on
(however, the indicator light will not illu-
minate) if the outside temperature is
more than 45ÉF (7ÉC). This dehumidifies
the air which helps defog the windshield.
The air recirculation mode automatically
turns off, allowing outside air to be drawn
into the passenger compartment which
helps defog the windshield.
Operating tips
cClear snow and ice from the wiper
blades and air inlet in front of the
windshield. This improves heater op-
eration.
cTo defog the side windows more effec-
tively when in bi-level or ventilation
mode, close the center vent and direct
the side vents toward the side windows.
cA slight delay may be experienced when
changing air control buttons. This is not a
problem, it is only the system motors and
solenoids switching from one outlet to
another.
AIR CONDITIONER OPERATION
Start the engine, move the fan control dial to
the desired (one to four) position, and select
an air control position before pushing in the
air conditioner button to activate the air

minate) if the outside temperature is
more than 45ÉF (7ÉC). This dehumidifies
the air which helps defog the windshield.The air recirculation mode automatically
turns off, allowing outside air to be drawn
into the passenger compartment which
helps defog the windshield.
Operating tips
cKeep windows and sun roof closed while
the air conditioner is in operation.
cAfter parking in the sun, drive for two or
three minutes with the windows open to
vent hot air from the passenger compart-
ment. Then, close the windows. This
allows the air conditioner to cool the
interior more quickly.
cThe air conditioning system should be
operated for about ten minutes at
least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
cIf the engine coolant temperature gauge
exceeds the H (hot) position, turn the air
conditioner off. See ``If your vehicle over-
heats'' in the ``In case of emergency''
section for additional information.

AUTOMATIC OPERATION
Push the AUTOMATIC button and select the
desired temperature. The selected tempera-
ture and AUTO show in the display window.
The EATC heats or cools to achieve the set
temperature.
When in AUTOMATIC and weather conditions
require heat, air is sent to the floor. However,
a feature is included in the EATC to prevent
blowing cold air to the floor if the engine
coolant is not warm enough to allow heating.
In three or four minutes the fan speed gradu-
ally increases and airflow changes to the floor.
If unique conditions exist, such as window
fogging, the five override buttons allow spe-
cific airflow selection. The thumbwheel al-
lows you to adjust the fan speed to suit your
needs.
Temperature selection
TheTEMPbutton on the left side of
the control panel is for temperature selec-
tion. The
side lowers the set tempera-
ture, and theside raises the set tem-
perature. Press and hold either side of the
button to rapidly change the temperature
setting in one degree increments to either
65ÉF (18ÉC) or 85ÉF (29ÉC). If you wantcontinuous maximum cooling, push the
side of the TEMP button until 60ÉF
(16ÉC) shows in the display window. The
EATC cools at maximum and disregards the
60ÉF (16ÉC) setting until a warmer tempera-
ture is selected. If you want continuous
maximum heating, push the
side of the
TEMP button until 90ÉF (32ÉC) shows in the
display window. The EATC provides maxi-
mum heat regardless of the 90ÉF (32ÉC)
setting until a cooler temperature is se-
lected.
Fan speed and thumbwheel
Your EATC automatically adjusts the fan
speed to the existing conditions. To control
the fan speed yourself, use the thumbwheel
located at the extreme right side of the
EATC control panel. Using the thumbwheel
cancels the automatic fan speed control,
and causes a
to appear in the display
window. Rotate the thumbwheel up for HI
speeds and down for LO speeds.
To return to auto fan control, press the
AUTOMATIC button.
AIR CONTROL BUTTONS
Your EATC has five buttons which allow you
to make special selections. The buttons aregrouped in the middle of the EATC panel
and allow you to determine airflow location.
Pressing any of the air control buttons
changes airflow location only, and does not
affect the ability of the system to control
temperature or fan speed. Return to fully
automatic operation by pushing the AUTO-
MATIC button.
Push this button for airflow to the front and
rear floor outlets and windshield at the same
time. The
indicator light comes on,
and the display window shows the set tem-
perature.
Press this button to obtain maximum airflow
to the windshield. Adjust the temperature
setting as required for defrosting. The
indicator light comes on, and the
display window shows the set temperature.
When the outside temperature is about
45ÉF (7ÉC) or above, the air is dehumidified
to prevent window fogging.

The power assisted steering is designed to
use a hydraulic pump, driven by the engine,
to aid steering.
If the engine stops or the drive belt breaks,
you still have control of the vehicle. How-
ever, much greater steering effort is
needed, especially in sharp turns and at low
speeds.
WARNING
If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be much harder to operate.The brake system has two separate hydrau-
lic circuits. If one circuit develops a problem
you will still have braking at two wheels.
Vacuum assisted brake
The brake booster aids braking by using
engine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on
the brake pedal is required to stop the
vehicle, and stopping distance is longer.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As a
result, your braking distance is longer and
the vehicle may pull to one side during
braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal
to heat up the brakes. Do this until the
brakes return to normal. Avoid driving the
vehicle at high speeds until the brakes
function correctly.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This overheats the brakes,
wears out the brake linings and pads fasterand reduces fuel economy.
To help save the brakes and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down
a slope or long grade. Overheated brakes
may reduce braking performance and could
result in loss of vehicle control.WARNING
cWhile driving on a slippery surface,
be careful when braking, accelerat-
ing or downshifting. Abrupt braking
actions or sudden acceleration
could cause the wheels to skid and
result in an accident.
cIf the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.

CAUTION
Automatic transmission models can-
not be push or tow started. This may
cause transmission or other vehicle
damage.If your vehicle is overheating (indicated by
an extremely high temperature gauge read-
ing), or if you feel a lack of engine power,
detect abnormal noise, etc., take the follow-
ing steps:
WARNING
cDo not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
cTo avoid the danger of being
scalded, never remove the radiator
cap while the engine is still hot.
When the radiator cap is removed,
pressurized hot water will spurt out,
possibly causing serious injury.
cDo not open the hood if steam is
coming out.
1. Move the vehicle safely off the road,
apply the parking brake and move the
gearshift lever to the P (Park) position.
Do not stop the engine.
2. Turn off the air conditioner switch. Open
all the windows, move the temperature
control dial to warm and fan control knob
to four.3. If engine overheating is caused by climb-
ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 RPM)
until the temperature gauge indication
returns to normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. Wait until
no steam or coolant can be seen before
proceeding.
5. Open the hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check if the cooling fan is run-
ning. The radiator hoses and radiator
should not leak water. If coolant is leak-
ing or the cooling fan does not run, stop
the engine.
