Air intake control
This is used to select the outside
(fresh) air position or recirculated air position.
To change the air intake control posi‐
tion, push the control button.
Recirculated air position
With the recirculated air position selected, air from
the passenger compart‐ment will be drawnthrough the heating sys‐
tem and heated or cooled
according to the functionselected.
Outside (fresh) air position
With the outside (fresh) air position selected, air
enters the vehicle fromoutside and is heated or
cooled according to thefunction selected.
NOTICE
Prolonged operation of the heater in
the recirculated air position (without
air conditioning selected) may cause
fogging of the windshield and side
windows and the air within the pas‐
senger compartment may become
stale.
In addition, prolonged use of the air
conditioning with the recirculated air
position selected will result in exces‐
sively dry air in the passenger com‐
partment.
WARNING
•Continue using the climate controlsystem in the recirculated air posi‐tion may allow humidity to in‐crease inside the vehicle whichmay fog the glass and obscure vis‐ibility.
•Do not sleep in a vehicle with theair conditioning or heating systemon. It may cause serious harm ordeath due to a drop in the oxygenlevel and/or body temperature.
•Continue using the climate controlsystem in the recirculated air posi‐tion can cause drowsiness orsleepiness, and loss of vehicle con‐trol. Set the air intake control tothe outside (fresh) air position asmuch as possible while driving.

WINDSHIELD DEFROSTING AND DEFOGGING
Automatic climate control
system
To defog inside windshield
0+'
1. Set the fan speed to the desiredposition.
2. Select the desired temperature.
3. Press the defroster button (
).
4. The air conditioning will turn on ac‐ cording to the detected ambient
temperature and outside (fresh) air
position will be selected automati‐
cally. If the air conditioning and outside
(fresh) air position are not selected au‐
tomatically, adjust the corresponding
button manually. If the
position is
selected, lower fan speed is adjusted to a higher fan speed.
To defrost outside windshield
0+'
1. Set the fan speed to the highest position.
2. Set the temperature to the ex‐ treme hot (HI) position.
3. Press the defroster button
. 4. The air conditioning will turn on ac‐
cording to the detected ambient
temperature and outside (fresh) air
position will be selected automati‐
cally.
Operation tips
• For maximum defrosting, set the temperature 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,
outside rear view mirrors, and all side windows.
• Clear all snow and ice from the hood and air inlet in the cowl grill to im‐
prove heater and defroster efficiency
and to reduce the probability of fog‐
ging up the inside of the windshield.

(Continued)
Do not use the or positionduring cooling operation in extreme‐ly humid weather. The difference be‐tween the temperature of the out‐side air and the windshield couldcause the outer surface of the wind‐shield to fog up, causing loss of visi‐bility. In this case, set the mode se‐lection to the position and fanspeed control to the lower speed.
Defogging logic (if equipped)
To reduce the possibility of fogging up
the inside of the windshield, the air in‐ take or air conditioning are controlled
automatically according to certain con‐
ditions such as the
or position.
To cancel or return to the defogging
logic, do the following.
Automatic climate control system
1. Turn the ignition switch to the ON position.
2. Press the defrost button (
).
3. While pressing the air conditioning button (A/C), press the air intake
control button at least 5 times
within 3 seconds.
The indicator on the air intake button will blink 3 times. It indicates that the
defogging logic is canceled or returned
to the programmed status.
If the battery has been discharged or disconnected, it resets to the defog
logic status.
Auto defogging system (Only
for automatic climate control
system, if equipped)
0+'-
Auto defogging reduces the possibility
of fogging up the inside of the wind‐ shield by automatically sensing the
moisture of inside the windshield.
This indicator illuminates when the auto defogging
system senses the moistureof inside the windshield andoperates.
If more moisture is in the vehicle, high‐
er steps operate as follow.
