Features of your vehicle
Air intake control
This is used to select the outside
(fresh) air position or recirculated air
position.
To change the air intake control posi-
tion, push the control button.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.
✽ ✽NOTICE
While driving at high speed with the
recirculation air position mode,
fresh air may automatically enter
the vehicle to provide ventilation of
the inside air.
WARNING
Continuous use of the climate
control system in the recircu-
lated air position can cause
drowsiness or sleepiness, and
loss of vehicle control. Set the
air intake control to the outside
(fresh) air position as much as
possible while driving.
Continued climate control system operation in the recir-
culated air position may allow
humidity to increase inside
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 harm or death due to a
drop in the oxygen level
and/or body temperature.

It should be noted that prolonged
operation of the heating in recirculat-
ed air position will cause fogging of
the windshield and side windows and
the air within the passenger com-
partment 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 control knob allows
you to control the fan speed of the
airflow in the vehicle.
To change the fan speed:
Turn the knob to the right (+) to
increase fan speed.
Turn the knob to the left (-) to decrease fan speed.
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 system off.

OFF mode
Press the OFF button to turn off the
air climate control system. However,
you can still operate the mode and
air intake buttons as long as the igni-
tion switch is in the ON position.
System operation
Ventilation
1. Set the mode to the position.
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. Set the mode to the position.
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 (if
equipped) on.
If the windshield fogs up, set the mode to the or position. Operation Tips
To keep dust or unpleasant fumes
from entering the vehicle 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 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. Press the air
conditioning button.
2. Set the mode to the position.
3. Set the air intake control to the outside air or recirculated air posi-
tion.
4. Adjust the fan speed control and temperature control to maintain
maximum comfort.
✽ ✽NOTICE- Excessive A/C
When using the air conditioning sys-
tem, monitor the engine coolant
closely while driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine
overheating and potential engine
damage. Continue to use the blower
fan but turn the air conditioning
system off if the engine coolant tem-
perature gauge indicates engine
overheating.
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 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.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance.
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 is a normal sys-
tem operation characteristic. 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.
After sufficient cooling has been
achieved, switch back from the
recirculated air to the fresh outside
air position.
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.

Features of your vehicle
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 fil-
ter 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 or
rough roads, more frequent air
conditioner 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 impact on the air con-
ditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized HYUNDAI dealer.
The air conditioning system should be
serviced by an authorized HYUNDAI
dealer.
CAUTION - Compressor
damage
It is important that the correct
type and amount of oil andrefrigerant is used. Otherwise,damage to the compressor andabnormal system operation mayoccur.
