Features of your vehicle64 4Recirculated air position
The indicator light on the
button is illuminated when
the recirculated air position
is selected.
With the recirculated air
position selected, air from
passenger compartment
will be drawn through the

position selected, air enters
the vehicle from outside and
is heated or cooled accord-
ing to the function selected.
✽ ✽
NOTICEIt should be noted that prolonged oper-
ation of the heating in recirculated air
position will cause fogging of the wind-
shield and side windows and the air
within the passenger compartment will
become stale.
In addition, prolonged use of the air
conditioning with the recirculated air
position selected, will result in excessive-
ly dry air in the passenger compart-
ment.
WARNING
• Continued climate control system
operation in the recirculated air
position may allow humidity to
increase inside vehicle which
may fog the glass and obscure
visibility.
Do not sleep in a vehicle with 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 climate control system
operation in the recirculated 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 driv-
ing.

Features of your vehicle66 4Operation 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 temperature
control to desired temperature.
Air conditioning (if equipped) All Hyundai Air Conditioning Systems are
filled with environmentally friendly
R-134a refrigerant which is not damag-
ing to the ozone layer.
1. Start the engine. Push 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.
When maximum cooling is desired, set
the temperature control to the extreme
left position, set the mode control to
the MAX A/C position, then set the fan
speed control to the highest speed.
✽ ✽
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.

Features of your vehicle
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 win-
dows on rainy or humid days, decrease
the humidity inside the vehicle by oper-
ating 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 if only for a few minutes to
ensure maximum system perform-
ance.
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 does
provide maximum cooling, however,
continual operation in this mode may
cause the air inside the vehicle to
become stale.
Climate control air filter
(if equipped)The 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 deal-
er.

CAUTION
Replace the filter every 10,000
miles (15,000 km) or once a year.
If the car is being driven in severe
conditions such as dusty, rough
roads, more frequent climate con-
trol air filter inspections and
changes are required.
When the air flow rate is sudden-
ly decreased, the system should
be checked at an authorized deal-
er.

Features of your vehicle68 4Checking 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 bad influ-
ence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized Hyundai dealer.✽ ✽
NOTICEWhen the performance of the air condi-
tioning system is reduced it is important
that the correct type and amount of oil
and refrigerant is used. Otherwise, dam-
age to the compressor and abnormal
system operation may occur.
CAUTION
The air conditioning system should
be serviced by an authorized
Hyundai dealer. Improper service
may cause serious injury to the per-
son performing the service.
