Recirculated air position
With the recirculated air
position selected, air
from the passenger
compartment will be
drawn through the heat-
ing system and heated
or cooled according to
the function selected.
Outside (fresh) air position
With the outside (fresh)air position selected, air
enters the vehicle from
outside and is heated or
cooled according to the
function selected.
Information
Using the system in the fresh air posi-
tion is recommended.
Prolonged operation of the heater in
the recirculated air position (without
air conditioning selected) can cause
fogging of the windshield and side
windows and the air within the pas-
senger compartment will 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.
i
Continued use of the climate
control system operation in
the recirculated air position
can cause drowsiness or
sleepiness, that may cause
loss of vehicle control result-
ing in an accident. Set the air
intake control to the outside
(fresh) air position as much as
possible while driving.
Continued use of the climate
control system operation in
the recirculated air position
(without the air conditioning
selected) may allow humidity
to increase inside the vehicle
which may fog the glass and
obscure visibility.
Do not sleep in a vehicle with
the air conditioning or heating
system on. It may cause seri-
ous injury or death due to a
drop in the oxygen level
and/or body temperature.

Air conditioning system operation tips
If the vehicle has been parked indirect sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
After sufficient cooling has been achieved, switch back from the
recirculated air to the fresh outside
air position.
To help reduce moisture inside of the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air con-
ditioning system with the windows
and sunroof closed.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance.
If you operate air conditioner exces- sively, the difference between the
temperature of the outside air and
that of 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 to the lower
speed.
System Maintenance
Climate control air filter
This filter is installed behind the glove
box. It filters the dust or other pollu-
tants that enter the vehicle through the
heating and air conditioning system.
Have the climate control air filter be
replaced by an authorized HYUNDAI
dealer according to the maintenance
schedule. If the vehicle is being driven
in severe conditions such as dusty or
rough roads, more frequent air condi-
tioner filter inspections and changes
are required.
If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized HYUNDAI dealer.
Checking the amount of air conditioner refrigerant andcompressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
reduces the performance of the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized HYUNDAI dealer.
It is important that the correct
type and amount of oil and refrig-
erant is used. Otherwise, damage
to the compressor and abnormal
system operation may occur.

Temperature control
Turn the knob to the right to increase
the temperature. Turn the knob to the
left to decrease temperature.
The temperature will increase or
decrease by 1°F/0.5°C for each incre-
mental location. When set to the low-
est temperature setting, the air condi-
tioning will operate continuously.
Air intake control
This button is used to select the out-
side (fresh) air position or recirculat-
ed air position.
Recirculated air position
With the recirculated airposition selected, air
from the passenger
compartment will be
drawn through the heat-
ing system and heated
or cooled according to
the function selected.
Outside (fresh) air position
With the outside (fresh) air position selected, air
enters the vehicle from
outside and is heated or
cooled according to the
function selected.
Information
Using the system in the fresh air position
is recommended.
Prolonged operation of the heater in the
recirculated air position (without air
conditioning selected) can cause fogging
of the windshield and side windows and
the air within the passenger compart-
ment will 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.

For maximum defrosting, set thetemperature 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 win-
dow, side view mirrors, and all side
windows.
Clear all snow and ice from the hood and air inlet in the cowl grill to
improve heater and defroster effi-
ciency and to reduce the probability
of fogging up the inside of the wind-
shield.
If the engine temperature is still
cold after starting, then a brief
engine warm up period may be
required for the vented air flow to
become warm or hot.Manual Climate Control System
To defog inside windshield
1. Select any fan speed except "0" position.
2. Select the desired temperature.
3. Select the or position.
4. The outside (fresh) air will be select- ed automatically. Additionally, the air
conditioning will automatically oper-
ate if the mode is selected to the position.
If the air conditioning and outside
(fresh) air position are not selected
automatically, press the correspon-
ding button manually.

Windshield heating
Do not use the or posi-
tion during cooling operation in
extremely humid weather. The
difference between the temper-
ature of the outside air and that
of the windshield could cause
the outer surface of the wind-
shield to fog up, causing loss of
visibility could cause an acci-
dent resulting in serious injury
or death. In this case, set the
mode selection knob or button
to the position and fan
speed control knob or button to
a lower speed.

Auto Defogging System
(Only for Automatic Climate
Control System, if equipped)
Auto defogging reduces the possibil-
ity of fogging up the inside of the
windshield by automatically sensing
the moisture on inside the wind-
shield.
The auto defogging system operates
when the heater or air conditioning is
on.
Information
The auto defogging system may not
operate normally, when the outside
temperature is below 50 °F (-10 °C).When the Auto Defogging
System operates, the indi-
cator will illuminate.
If high levels of moisture are sensed in
the vehicle, the Auto Defogging System
will operate in the following order:
Step 1: Outside air position
Step 2: Operating the air conditioning
Step 3: Blowing air toward the wind- shield
Step 4: Increasing air flow toward the windshield
If the air conditioning is off or recircu-
lated air position is manually selected
while Auto Defogging System is ON,
the Auto Defogging System Indicator
will blink 3 times to signal that the
manual operation has been canceled.
To cancel or reset the
Auto Defogging System
Press the front windshield defroster
button for 3 seconds when the ignition
switch is in the ON position. When the
Auto Defogging System is canceled,
the ADS OFF symbol will blink 3 times
and ADS OFF will be displayed on the
climate control information screen. When the Auto Defogging System is
reset, the ADS OFF symbol will blink
6 times without a signal.
Information
• When the air conditioning is turned
on by Auto defogging system, if you
try to turn off the air conditioning, the
indicator will blink 3 times and the air
conditioning will not be turned off.
• For efficiency, do not select recircu- lated air position while the Auto
defogging system is operating.
• When Auto defogging mode is selected, fan speed, temperature and
intake mode which is adjusted man-
ually are canceled for better defog-
ging result.
Do not remove the sensor cover
located on the upper end of the
windshield glass.
Damage to system parts could
occur and may not be covered by
your vehicle warranty.
