While the engine is running, push the
switch to cool the driver's seat or the
front passenger's seat.
Each time you push the switch, theairflow changes as follows:
The air v entilation seats default to
the OFF position whenever the
ignition switch is turned to the ON
position. To prevent damage to the air ven-
tilation seat system and seats:
Use the air ventilation seats
ONLY when the air conditioning
is on. Using the air ventilation
seats for prolonged periods of
time with the air conditioning off
could cause the air ventilation
seats to malfunction.
Never use a solvent such as paint thinner, benzene, alcohol
or gasoline to clean the seats.
Avoid spilling liquids on the sur- face of the front seats and seat-
backs; this may cause the air
vent holes to become blocked
and not work properly.
Do not place materials such as plastic bags or newspapers
under the seats. They may block
the air intake causing the air
vents to not work properly.
Do not change the seat covers. It may damage the air ventilation
seats.
(Continued)(Continued)
If the air vents do not operate,
restart the vehicle. If there is no
change, have your vehicle
inspected by an authorized
HYUNDAI dealer.NOTICE

A/C MAX-Level (B, D)
The A/C MAX mode is used to cool
the inside of the vehicle more quick-
ly. Air flow is directed toward the
upper body and face.
In this mode, the air conditioning and
the recirculated air position will be
selected automatically.
After the vehicle interior has cooled
down initially, resume using normal
A/C mode. Continuous use of A/C
MAX mode is not recommended.
Instrument panel vents
The outlet vents can be opened ( )
or closed ( ) separately using the
thumbwheel.
Also, you can adjust the direction of
air delivered from these vents using
the vent control lever as shown.
Temperature control
The temperature will increase by
turning the knob to the right.
The temperature will decrease by
turning the knob to the left.

Air intake control
This button is used to select the out-
side (fresh) air position or recirculat-
ed air position.
Recirculated air position
The indicator light on the
button illuminates when
the recirculated air posi-
tion is selected.
With the recirculated air position selected, air
from the passenger com-
partment will be drawn
through the climate con-
trol system and heated
or cooled according to
the function selected.
Outside (fresh) air position
The indicator light on the
button will turn off when
the outside (fresh) air
position is selected.
With the outside (fresh) air position selected, air
enters the vehicle from
outside and is heated or
cooled according to the
function selected.
Information
Prolonged use of the air conditioning
with the recirculated air position
selected will result in excessively dry
air in the passenger compartment.

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.

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.

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 desired temperature.
Air conditioning
All HYUNDAI Air Conditioning
Systems are filled with environmen-
tally friendly R-1234yf refrigerant.
1. Start the engine.
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.

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 can cause engine over-
heating. Continue to use the blow-
er fan, but turn the air condition-
ing system off if the engine tem-
perature gauge indicates engine
overheating.
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
replaced by an authorized HYUNDAI
dealer according to the maintenance
schedule. If the car 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
has a negative influence on 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.

Because the refriger-
ant is mildly inflam-
mable 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.
Otherwise, it may cause dam-
age to the vehicle and personal
injury.
