Adjusting the driver and passenger
side temperature individually
Press the "SYNC" button again to
operate the driver and passenger
side temperature individually. The
button indicator will turn off.
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 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.

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 voice recognition, fan speed
may automatically slow down for a
couple of minutes when you activate
voice recognition or hands free.Operating the fan when the
Engine Start/Stop button is in the
ON position could cause the bat-
tery to discharge. Operate the fan
when the vehicle is in the ready
( ) mode.
NOTICE
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.

Driver only
If you press the DRIVER ONLY but-
ton( ) and the indicator light
illuminates, air mostly blows in the
direction of the driver’s seat.
However, some of the air may come
out of other seating position ducts to
keep indoor air pleasant.
If you use the button with no passen-
ger in the front passenger seat, ener-
gy consumption will be reduced.
DRIVER ONLY button will be turned
off under the following conditions:
1) Defrost on (the DRIVER ONLYbutton indicator is not turned off)

System Operation
Ventilation
1. Select the Face Level mode.
2. Set the air intake control to theoutside (fresh) air position.
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 theoutside (fresh) air position.
3. Set the temperature control to the desired position.
4. Set the fan speed control to the desired speed.
5. If dehumidified heating is desired, turn the air conditioning system on.
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 recircu-
lated air position. Return the con-
trol to the fresh air position when
the irritation has passed. This will
help keep the driver alert and com-
fortable.
To prevent the inside of the wind- shield from fogging, set the air
intake control to the fresh air posi-
tion and fan speed to the desired
position, turn on the air conditioning
system, and adjust the temperature
control to the desired temperature.
Air conditioning
All HYUNDAI Air Conditioning
Systems are filled with environmen-
tally friendly R-134a refrigerant.
1. Start the vehicle.
2. Push the air conditioning button.
3. Set the mode to the Face Level mode.
4. Set the air intake control to the recirculated air position. However,
prolonged operation of the recircu-
lated air position will excessively
dry the air. In this case, change the
air position.
5. Adjust the fan speed control and temperature control to maintain
maximum comfort.
When maximum cooling is desired,
set the temperature control to the
extreme left position then set the fan
speed control to the highest speed.

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
conditioning system with the win-
dows 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 excessively, 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 driv-
en in severe conditions such as dusty
or rough roads, more frequent air
conditioner 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.

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.
Because the refriger-
ant is at very high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and certified
technicians. It is important that
the correct type and amount of
oil and refrigerant is used, oth-
erwise damage to the vehicle
and personal injury may occur.
