Air intake control
This is used to select the outside (fresh)
air position or recirculated air position.
To change the air intake control position,
push the control button.
Recirculated air position
With the recirculated air
position selected, air from the
passenger compartment will
be drawn through the heating
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 primarily in Fresh mode
and Recirculation mode only when needed
is recommended for best results.
Prolonged operation of the heater in
Recirculation mode and without the A/C
ON can cause fogging of the windshield.
In addition, prolonged use of the A/C
ON in Recirculation mode may result in
excessively dry, dehumidified air in the
cabin.
WARNING
• Continued use of the climate control
system operation in Recirculation
mode for a prolonged 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 windshield 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
prolonged periods of time. Doing so
may increase the levels of carbon
dioxide in the cabin which may lead
to serious injury or death.

Air conditioning system operation tips
• If the vehicle has been parked in dir
ect 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 windows
and sunroof closed.
• Use the air conditioning system every month only for a few minutes
to ensure maximum system
performance.
• 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
Cabin air filter
OIK047401LOIK047401L[A] : Outside air, [B] : Recirculated air
[C] : Cabin 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 conditioning system.
Have the cabin air filter 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
cabin air filter inspections and changes
are required.
If the air flow rate suddenly decreases,
the system should be checked at an
authorized HYUNDAI dealer.

WINDSHIELD DEFROSTING AND DEFOGGING
WARNING
Windshield heating
Do not use the
or position
during cooling operation in extremely
humid weather. 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 could cause
an accident 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.
• For maximum defrost performance, 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 position.
• Before driving, clear all snow and ice from the windshield, rear window,
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
efficiency and to reduce the
probability of fogging up the inside of
the windshield.
NOTICE
If you start the vehicle when the
weather is cold, more adequate way to
heat the cabin is described below.
1. Turn off or lower the blower, right after engine starting, because
engine temperature is still low and
the air flow is cold.
2. After few minutes of engine warm up, turn the blower to low to medium
speed and set the temperature
control to Hot.

WARNING
Carbon monoxide (CO) gas is toxic. Breathing CO can cause unconsciousness and
death.
Engine exhaust contains carbon monoxide which cannot be seen or smelled.
Do not inhale engine exhaust.
If at any time you smell engine exhaust inside the vehicle, open the windows
immediately. Exposure to CO can cause unconsciousness and death by asphyxiation.
Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the
oil or for any other purpose. If you hear a change in the sound of the exhaust or if you
drive over something that strikes the underneath side of the vehicle, have the exhaust
system checked as soon as possible by an authorized HYUNDAI dealer.
Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous
practice. Run the engine only long enough to start the engine and to move the vehicle
out of the garage.
Avoid idling the engine for prolonged periods with people inside the vehicle.
If it is necessary to idle the engine for a prolonged period with people inside the
vehicle, be sure to do so only in an open area with the air intake set at "Fresh" and fan
control set to high so fresh air is drawn into the interior.
Keep the air intakes clear.
To assure proper operation of the ventilation system, keep the ventilation air intakes
located in front of the windshield clear of snow, ice, leaves, or other obstructions.
If you must drive with the trunk open:
Close all windows.
Open instrument panel air vents.
Set the air intake control at "Fresh", the air flow control at "Floor" or "Face", and the fan
control set to high.
