Information
Operating the system primarily in
Fresh mode is recommended. Use
Recirculation mode temporarily only
when needed.
Prolonged operation of the heater in
Recirculation mode and without the
A/C ON can cause fogging of the wind-
shield.
In addition, prolonged use of the A/C
ON in Recirculation mode may result in
excessively dry, dehumidified air in the
cabin and may promote formation of
musty vent odor due to stagnant air.
Fan speed control
The fan speed can be set as desired
by pushing the fan speed control but-
ton.
More air is delivered with higher fan
speeds.
Pressing the OFF button turns off the
fan.
Information
For better sound quality, fan speed
may automatically slow down for a
couple of minutes when you activate
voice recognition or hands free.

i
Continued use of the climate
control system operation in
Recirculation mode for a pro-
longed period of time may
cause drowsiness to the
occupants in the cabin. This
may lead to loss of vehicle
control which may lead to an
accident.
Continued use of the climate
control system operation in
Recirculation mode with the
A/C OFF may allow humidity
to increase inside the cabin.
This may cause condensation
to accumulate on the wind-
shield and obscure visibility.
Do not sleep in your vehicle or
remain parked in your vehicle
with the windows up and
either the heater or the air
conditioning ON for pro-
longed periods of time. Doing
so may increase the levels of
carbon dioxide in the cabin
which may lead to serious
injury or death.

mate control system off. You can still
operate the mode and air intake but-
tons as long as the ignition switch is
in the ON position.

System Operation
Cooling / Ventilation
1. Select the Face Level mode.
2. Set the air intake control to freshmode.
3. Set the temperature control to the desired position.
4. Set the fan speed control to the desired speed.
Heating
1. Select the Floor Level mode.
2. Set the air intake control to freshmode.
3. Set the temperature control to the desired position.
4. Set the fan speed control to the desired speed.
5. If desired, turn the air conditioning ON with the temperature control
knob set to heat in order to dehu-
midify the air before it enters into
the cabin.
If the windshield fogs up, select the
Floor & Defrost mode or press
the Front Defrost mode.
Operation Tips
To keep dust or unpleasant fumes from entering the car through the
ventilation system, temporarily set
the air intake control to the recir-
culation mode. Return the control
to the to fresh mode when the
unpleasant air outside has dimin-
ished. This will help keep the driv-
er alert and comfortable.
To help prevent the inside of the windshield from fogging, set the air
intake control to fresh mode and
the fan speed to the desired posi-
tion, turn on the air conditioning
system, and adjust the tempera-
ture control to the desired temper-
ature.
Air conditioning
Your HYUNDAI vehicle air condition-
ing system is filled with R-1234yf
refrigerant.
1. Start the engine.
2. Press the air conditioning button.
3. Select the Face Level mode.
4. Set the air intake control toRecirculation mode temporarily to
allow the cabin to cool quickly.
When the desired temperature in
the cabin is reached, change the
air intake control back to Fresh
mode.
5. Adjust the fan speed control and temperature control to maintain
maximum comfort.
When maximum cooling is desired,
set the temperature control to the
MAX A/C position, then set the fan
speed control to the highest setting.

Convenient features of your vehicle
When using the air conditioning
system, monitor the engine tem-
perature gauge closely while driv-
ing up hills or in heavy traffic
when outside temperatures are
high. Air conditioning system
operation when climbing a steep
grade or in high outside ambient
temperatures can cause engine
overheating. Continue to use the
fan, but turn the air conditioning
system off if the engine tempera-
ture gauge indicates engine over-
heating.
Air conditioning system operation
tips
If the vehicle has been parked in direct 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 recir-
culation mode to fresh mode. To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity
inside the vehicle by operating the
air conditioning system with the
windows and sunroof closed.
Use the air conditioning system every month only for a few min-
utes to ensure maximum system
performance.
If you operate air conditioner excessively, the difference
between the temperature of the
outside air and that of the wind-
shield could cause the outer sur-
face 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
Cabin air filter
[A] : Outside air, [B] : Recirculated air
[C] : Climate control air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
The cabin air filter is installed behind
the glove box. It filters the dust or
other pollutants that enter the vehicle
through the heating and air condi-
tioning system.

Have the cabin air filter replaced by
an authorized HYUNDAI dealer
according to the maintenance sched-
ule. If the vehicle is being driven in
severe conditions such as dusty or
rough roads and/or if transporting
pets or occupants smoke inside the
vehicle, then more frequent cabin air
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.
The air conditioning system should
be serviced by an authorized
HYUNDAI dealer.
Air Conditioning refrigerant label
The actual Air Conditioning refriger-
ant label in the vehicle may differ
from the illustration.
Each symbols and specification on
air conditioning refrigerant label
means as below :
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubri-
cant
Refer to chapter 8 for more detail
location of the air conditioning refrig-
erant label.
NOTICE
ODH043366
■ Example
Because the refrigerant
is mildly inflammable at
very high pressure, the
air conditioning system
should only be serv-
iced by trained and cer-
tified technicians. It is
important that the cor-
rect type and amount of oil and
refrigerant is used. Otherwise, it
may cause damage to the vehi-
cle and personal injury.
WARNING

3-158
Convenient features of your vehicle For maximum defrost perform-ance, set the temperature control
knob to the highest temperature
setting (rotated all the way to the
right) and the fan speed control to
the highest setting.
If warm air to the floor is desired while defrosting or defogging, set
the mode to the floor-defrost posi-
tion.
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 probabili-
ty of fogging up the inside of the
windshield.
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. Fresh mode will be selected auto- matically. Additionally, the air condi-
tioning will automatically operate if
the mode is selected to the
position.
Check to make sure the A/C is ON. If
the A/C ON LED is not illuminated,
press the A/C button once to turn the
air conditioner ON.

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.
