2ndand 3rdrow outlet vents (E, F, G, H) (G, H : if equipped)
The air flow of the 2
ndand 3rdrow outlet vents is controlled by the front climate
control system and delivered through the inside air duct of the floor (E, F, H).
The air flow of the 2
ndand 3rdrow outlet vents (E, F, H) may be weaker than
the instrument panel vents for the long air duct.
Close the air vents (F) in cold weather. The air flow of the 2
ndand 3rdrow
outlet vents may not be as warm during heating operation. (Use the 2ndand
3rdrow outlet vents (F, G) during cooling operation.)

Features of your vehicle
Recirculated air positionThe indicator light on the
button illuminates when
the recirculated air posi-
tion is selected.
With the recirculated air position selected, air
from the passenger
compartment will be
recirculated 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.✽ ✽NOTICE
Prolonged operation of the heater in
the recirculated air position (with-
out air conditioning selected) may
cause fogging of the windshield and
side windows and the air within the
passenger compartment may
become stale.
In addition, prolonged operation of
the air conditioning with the recir-
culated air position selected will
result in excessively dry air in the
passenger compartment. ■ Type A, B

WARNING
Continued use of the climate
control system operation in the
recirculated air position with-
out A/C 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. This may cause
serious harm or death due to
a drop in the oxygen level
and/or body temperature.
Continued use of the climate control system operation in
the recirculated air position
may cause drowsiness or
sleepiness and loss of vehicle
control. Set the air intake con-
trol to the outside (fresh) air
position as much as possible
while driving.

position for fan operation.
The fan speed control knob allows
you to control the fan speed of the air
flowing from the ventilation system.
To change the fan speed, turn the
knob to the right for higher speed or
left for lower speed.
Setting the fan speed control knob to
the "0" position turns off the fan.
To turn off the blowers
To turn off the blowers, turn the fan
speed control knob to the "0" posi-
tion.
Air conditioning
Press the A/C button to turn the air
conditioning system on (indicator
light will illuminate). Press the button
again to turn the air conditioning sys-
tem off.

Operation Tips
To prevent dust or unpleasant
fumes from entering the vehicle
through the ventilation system,
temporarily set the air intake con-
trol 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 driv-
er 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 conditioning system, and adjust
the temperature control to desired
temperature.Air conditioning
HYUNDAI Air Conditioning Systems
are filled with environmentally friend-
ly R-134a refrigerant.
1. Start the engine. Push the air con- ditioning button.
2. Set the mode to the position.
3. 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.
4. 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.
✽ ✽ NOTICE
• While 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 may 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.
• Opening the windows in humid weather while operating the air
conditioning system may create
water droplets inside the vehicle.
Since excessive water droplets
may cause damage to electrical
equipment, air conditioning
should only be used with the win-
dows closed.

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.
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.
During air conditioning system operation, you may occasionally
notice a slight change in engine
speed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.
During the winter months, use the air conditioning system every
month for a few minutes to ensure
maximum system performance.
When using the air conditioning system, you may notice clear water
dripping (or even puddling) on the
ground under the passenger side
of the vehicle. This condensation is
a normal system operation charac-
teristic. Operating the air conditioning sys-
tem in the recirculated air position
provides maximum cooling, how-
ever, 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 operation characteristic.
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.Climate control air filter
The climate control air filter installed
behind the glove box filters the dust
or other pollutants that come into the
vehicle from the outside through the
heating and air conditioning system.
If dust or other pollutants accumulate
in the filter over a period of time, the
air flow from the air vents may
decrease, resulting in moisture accu-
mulation on the inside of the wind-
shield even when the outside (fresh)
air position is selected. If this hap-
pens, have the climate control air filter
replaced by an authorized HYUNDAI
dealer.

✽
✽
NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in
severe conditions such as dusty,
rough roads, more frequent cli-
mate control air filter inspections
and changes are required.
• When the air flow rate suddenly decreases, the system should be
checked at an authorized
HYUNDAI dealer.
Checking the amount of air
conditioner refrigerant and
compressor 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.
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 air conditioning refrigerant
label.
WARNING
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.OHG045533N
