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
If your vehicle is equipped with the auto
defogging system, it is automatically acti-
vated when the conditions are met.
However, if you would like to cancel the
auto defogging system, press the front
defroster button 4 times within 2 seconds
while pressing the AUTO button. The
indicator will blink 3 times to notify you
that the system is cancelled. To use the
auto defogging system again, follow the
procedures mentioned above.
If the battery has been disconnected or
discharged, it resets to the auto defog-
ging status.
✽ ✽ 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.

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 (cool-
ing fan) is controlled by
engine coolant tempera-
ture, refrigerant pres-
sure 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 normal 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.
