✽NOTICE
Prolonged operation of the heating in
recirculated air position will cause fog-
ging of the windshield and side windows
and the air within the passenger com-
partment will become stale.
In addition, prolonged operation of the
air conditioning with the recirculated
air position selected, will result in exces-
sively dry air in the passenger compart-
ment.
Fan speed control
The fan speed can be set to the desired
speed by pressing the fan speed control
switch.
To change the fan speed press the
part of the switch for higher speed or
press the part of the switch for lower
speed.
To turn the fan speed control off, press
the OFF button.
Air conditioning
Press the A/C button to turn the air con-
ditioning system on (indicator light will
illuminate).
Press the button again to turn the air
conditioning system off.
WARNING
Continuous use of the climate con-
trol system in the recirculated air
position may allow humidity to
increase inside vehicle which may
fog the glass and obscure visibility.
Do not sleep in a vehicle with air conditioning or heating system on.
It may cause serious harm or death
due to a drop in the oxygen level
and/or body temperature.
Continuous use of the climate con- trol system in the reciruclated air
position can cause drowsiness or
sleepiness, and loss of vehicle
control. Set the air intake control to
the outside (fresh) air position as
much as possible while driving.

WINDSHIELD DEFROSTING AND DEFOGGING
For maximum defrosting, set the tem-perature control to the extreme
right/hot position and the fan speed
control to the highest speed.
If warm air to the floor is desired while defrosting or defogging, set the mode
to the floor-defrost position.
Before driving, clear all snow and ice from the windshield, rear window, out-
side rear view mirrors, and all side win-
dows.
Clear all snow and ice from the hood and air inlet in the cowl grill to improve
heater and defroster efficiency and to
reduce the probability of fogging up
the inside of the windshield.
Manual climate control system
To defog inside windshield
1. Select any fan speed except “0” posi- tion.
2. Select desired temperature.
3. Select the or position.
4. The outside (fresh) air will be selected automatically.
If the outside (fresh) air position is not
selected automatically, press the corre-
sponding button manually.

WARNING - Windshield heating
Do not use the or position
during cooling operation in
extremely humid weather. The dif-
ference between the temperature of
the outside air and the windshield
could cause the outer surface of
the windshield to fog up, causing
loss of visibility. In this case, set
the mode selection knob or button
to the position and fan speed
control knob or button to a lower
speed.

Defogging logic
To reduce the probability of fogging up
inside of the windshield, the air intake or
air conditioning are controlled automati-
cally according to certain conditions such
as or position. To cancel or
return to the defogging logic, do the fol-
lowings.
Manual climate control system
1. Turn the ignition switch to the ON posi-tion.
2. Turn the mode selection knob to the defrost position ( ).
3. Push the air intake control button at least 5 times within 3 seconds.
The indicator light in the air intake control
button will blink 3 times with 0.5 second
of interval. It indicates that the defogging
logic is canceled or returned to the pro-
grammed status.
If the battery has been discharged or dis-
connected, it resets to the defog logic
status.
Automatic climate control system
1. Turn the ignition switch to the ON posi- tion.
2. Select the defroster position pressing the defroster button ( ).
3. While pressing the air conditioning button (A/C), press the air intake con-
trol button ( ) at least 5 times with-
in 3 seconds.
The A/C display blinks 3 times with 0.5
second of interval. It indicates that the
defogging logic is canceled or returned to
the programmed status.
If the battery has been discharged or dis-
connected, it resets to the defog logic
status.

Auto defogging system (Only for
automatic climate control system, ifequipped)
Auto defogging reduces the probability of
fogging up the inside of the windshield by
automatically sensing the moisture of
inside the windshield.
The auto defogging system operates
when the heater or air conditioning is on. This indicator illuminates
when the auto defogging
system senses the moisture
of inside the windshield and
operates.
If more moisture is in the vehicle, higher
steps operate as follow. For example if
auto defogging does not defog inside the
windshield at step 1 Outside air position,
it tries to defog again at step 2 Blowing
air toward the windshield.
Step 1 : Outside air position
Step 2 :Blowing air toward the windshield
Step 3 : Increasing air flow toward the windshield
Step 4 : Operating the air conditioning
Step 5 : Maximizing the air conditioning
✽ ✽ NOTICE
If the A/C off or recirculated air position
is manually selected while the auto
defogging system is on, the auto defog-
ging indicator will blink 3 times to give
notice that manual operation is can-
celed.

CAUTION
Do not remove the sensor cover
located on the upper end of the pas-senger side windshield glass. Damage to the system parts couldoccur and may not be covered by your vehicle warranty.

ENGINE COOLANT
The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant level at least once a year, at the
beginning of the winter season, and
before traveling to a colder climate.
Checking the coolant level
WARNING- Removing
radiator cap
Never attempt to remove the radi-
ator cap while the engine is oper-
ating or hot. Doing so might lead
to cooling system and engine
damage. Also, hot coolant or
steam could cause serious per-
sonal injury.
(Continued)
(Continued)
Turn the engine off and wait untilit cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back while the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to
remove it.
Even if the engine is not operat- ing, do not remove the radiator
cap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.WARNING
The electric motor (cooling fan) is
controlled by engine coolant tem-
perature, refrigerant pressure and
vehicle speed. It may sometimes
operate even when the engine is
not running. Use extreme caution
when working near the blades of
the cooling fan so that you are not
injured by a rotating fan blades. As
the engine coolant temperature
decreases, the electric motor will
automatically shut off. This is a nor-
mal condition.
If your vehicle is equipped with
GDI, the electric motor (cooling fan)
may operate untill you disconnect
the negative battery cable.

CLIMATE CONTROL AIR FILTER (IF EQUIPPED)
Filter inspection
The climate control air filter should be
replaced according to the Maintenance
Schedule. If the vehicle is operated in
severely air-polluted cities or on dusty
rough roads for a long period, it should
be inspected more frequently and
replaced earlier. When you replace the
climate control air filter, replace it per-
forming the following procedure, and be
careful to avoid damaging other compo-
nents.
Filter replacement
1. With the glove box open, remove thestoppers on both sides.
2. Remove the climate control air filter.
