Seat cooler (if equipped)
The seat cooler is provided to cool the
front seats during hot weather by blowing
air through small vent hole on the surface
of the seats and seatbacks. While the
engine is running, push the rear portion
of the switch to cool the driver's seat or
the front passenger's seat (if equipped).
When the operation of the seat cooler is
not needed, keep the switches in the
OFF position.• Each time you push the switch, the air-
flow is changed as follows:
• When pressing the switch for more
than 1.5 seconds with the seat cooler
operating, the seat cooler will turn
OFF.
• The seat cooler defaults to the OFF
position whenever the engine start/
stop button is turned to the ON posi-
tion.

CAUTION
• The seat cooler is a supplemen-
tary cooling system. Use the cli-
mate control seat when the cli-
mate control system is on. Using
the climate control seat for pro-
longed periods of time with the
climate control system off could
cause the climate control seat
performance to impair.
• When cleaning the seats, do not
use an organic solvent such as
thinner, benzene, alcohol and
gasoline. Doing so may damage
the surface of the seats.
• Do not spill liquid such as water
or beverages on the surface of
the front seats and seatbacks, or
the air vent holes may be blocked
and prevented from working
properly.
• Do not place materials such as
plastic bags or newspapers under
the seats. The air vent may not
work properly as the air intake
can be blocked.
• When the air vent does not oper-
ate, restart the vehicle. If there is
no change, have your vehicle
inspected by an authorized
HYUNDAI dealer.

individually. Also, if the passenger side
temperature control switch (PASS) is
operated, it will automatically change
to the DUAL mode as well.
2. Turn the left temperature control knob
to adjust the driver side temperature.
Turn the right temperature control
knob to adjust the passenger side tem-
perature.
When the driver side temperature is set
to the highest (HI) or lowest (Lo) temper-
ature setting, the DUAL mode is deacti-
vated for maximum heating or cooling.Adjusting the driver and passenger side
temperature equally
1. Press the DUAL button again to deac-
tivate DUAL mode. The passenger
side temperature will be set to the
same temperature as the driver side.

• If the windshield fogs up, set the mode
to the
orpush the front defrost but-
ton ().Operation Tips
• To keep dust or unpleasant fumes from
entering the car through the ventilation
system, temporarily set the air intake
control to the recirculated air position.
Be sure to return the control to the
fresh air position when the irritation
has passed to keep fresh air in the
vehicle. This will help keep the driver
alert and comfortable.
• Air for the heating/cooling system is
drawn in through the grilles just ahead
of the windshield. Care should be
taken that these are not blocked by
leaves, snow, ice or other obstructions.
• To prevent interior fog on the wind-
shield, set the air intake control to the
fresh air position and fan speed to the
desired position, turn on the air condi-
tioning system, and adjust the temper-
ature control to desired temperature.

Air conditioning
HYUNDAI Air Conditioning Systems are
filled with environmentally friendly
R-134a refrigerant.
1. Start the engine. Press the air condi-
tioning button.
2. Set the mode to the position.
3. Set the air intake control to the outside
air or recirculated air position.
4. Adjust the fan speed control and tem-
perature control to maintain maximum
comfort.
✽NOTICE
• When using the air conditioning sys-
tem, monitor the temperature gauge
closely while driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine over-
heating. Continue to use the blower
fan but turn the air conditioning sys-
tem off if the temperature gauge indi-
cates engine overheating.
• When opening the windows in humid
weather air conditioning may create
water droplets inside the vehicle.
Since excessive water droplets may
cause damage to electrical equipment,
air conditioning should only be run
with the windows closed.
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.
• To help reduce moisture inside of the
windows on rainy or humid days,
decrease the humidity inside the vehi-
cle by operating the air conditioning
system.
• During air conditioning system opera-
tion, you may occasionally notice a
slight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
• Use the air conditioning system every
month only for a few minutes to ensure
maximum system performance.• When using the air conditioning sys-
tem, you may notice clear water drip-
ping (or even puddling) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic.
• Operating the air conditioning system
in the recirculated air position provides
maximum cooling, however, continual
operation in this mode may cause the
air inside the vehicle to become stale.
• During cooling operation, you may
occasionally notice a misty air flow
because of rapid cooling and humid air
intake. This is a normal system opera-
tion characteristics.

Features of your vehicle
• For maximum defrosting, set the tem-
perature 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, out-
side rear view mirrors, and all side win-
dows.
• Clear all snow and ice from the hood
and air inlet in the cowl grill to improve
heater and defroster efficiency and to
reduce the probability of fogging up the
inside of the windshield.
To defog inside windshield
1. Set the fan speed to the desired posi-
tion.
2. Select desired temperature.
3. Press the defrost button ( ).
4. The air conditioning will be turned on
according to the detected ambient tem-
perature and outside (fresh) air posi-
tion will be selected automatically.
If the air conditioning and outside (fresh)
air position are not selected automatical-
ly, adjust the corresponding button man-
ually. If the position is selected,
lower fan speed is adjusted to a higher
fan speed.
WINDSHIELD DEFROSTING AND DEFOGGING
WARNING- Windshield
heating
Do not use the or position
during cooling operation in
extremely humid weather. The dif-
ference 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.
