✽
✽NOTICE• While using the air conditioning sys-
tem, monitor the engine temperature
gauge closely while driving up hills or
in heavy traffic when outside temper-
atures 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 engine temperature
gauge indicates engine overheating.
• Opening the windows in humid weather while air conditioning oper-
ates may create water droplets inside
the vehicle. Since excessive water
droplets may cause damage to electri-
cal equipment, air conditioning
should only be used 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 characteristic.
 If you operate air conditioner exces- sively, the difference between the tem-
perature 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 con-
trol to the lower speed.

4Climate control air filterThe climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the vehi-
cle 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 accumulation on the inside of
the windshield 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 climate control air fil-
ter 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 con-
ditioner refrigerant and compres-
sor lubricantWhen the amount of refrigerant is low,
the performance of the air conditioning 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.✽ ✽ NOTICEIt is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
and abnormal system operation may
occur.

WARNING
The air conditioning system should
be serviced by an authorized
HYUNDAI dealer. Improper service
may cause serious injury to the

4Automatic heating and air condi-
tioningThe automatic climate control system is
controlled by simply setting the desired
temperature.
The Full Automatic Temperature Control
(FATC) system automatically controls the
heating and cooling system as follows;
1. Push the AUTO button. The modes,
fan speeds, air intake and air-condi-
tioning will be controlled automatically
by the temperature setting. 2. Turn the temperature control knob to
set the desired temperature.
If the temperature is set to the lowest
setting, the air conditioning system will
operate continuously.
3. To turn the automatic operation off, press any button except the tempera-
ture control knob. If you press the
mode selection button, air conditioning
button, defrost button or air intake con-
trol button, or the fan speed button, the
selected function will be controlled
manually while other functions operate
automatically.
For your convenience and to improve the
effectiveness of the climate control, use
the AUTO button and set the temperature
to 73°F (23°C).

Recirculated air positionWith the recirculated airposition selected, air from
the passenger compart-
ment 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 accord-
ing to the function selected.✽ ✽NOTICEProlonged operation of the heater in the
recirculated air position (without air
conditioning selected) may cause fog-
ging of the windshield and side windows
and the air within the passenger com-
partment may become stale.
In addition, prolonged use of the air con-
ditioning with the recirculated air posi-
tion selected will result in excessively dry
air in the passenger compartment.
Fan speed controlThe fan speed can be set to the desired
speed by pushing the fan speed control
button.
To change the fan speed, press the right
of the button ( ) for higher speed, or
press the left of the button ( ) for lower
speed. To turn the fan speed control off,
press the OFF button.
WARNING
 Continued use of the climate con-
trol system operation in the recir-
culated air position 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 serious harm or
death due to a drop in the oxygen
level and/or body temperature.
 Continued use of the climate con- trol system operation in the recir-
culated 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.
