Information
Prolonged operation of the heater in
the recirculated air position (without
air conditioning selected) may cause
fogging of the windshield and side
windows and the air within the pas-
senger compartment may 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 can be set to the
desired speed by pushing the fan
speed control button.
The higher the fan speed is, the
more air is delivered.
Pressing the OFF button turns off the
fan.
i
Continued climate control system operation in the recir-
culated air position may allowhumidity 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 seri-ous harm or death due to a
drop in the oxygen level
and/or body temperature.
Continued climate control system operation in the recir-culated air position can cause
drowsiness or sleepiness,
and loss of vehicle control.
Set the air intake control tothe outside (fresh) air position
as much as possible whiledriving.

Operating the fan speed when the
Engine Start/Stop button is in theON position could cause the bat-
tery to discharge. Operate the fan
speed when hybrid system is run-ning.
Driver Only
If you press the DRIVER ONLY but-
ton ( ) and the indicator light illumi-
nates, cold air mostly blows in the
direction of the driver’s seat.
However, some of the cold air may
still come out of other vents to keepindoor air pleasant.
If you use the button with no passen- ger in the front passenger seat, ener-gy consumption will be reduced.DRIVER ONLY button will be turned
off under the following conditions: 1) Defrost on2) SYNC on
3) Adjusted front passenger seat
temperature
4) DRIVER ONLY button pushed again

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 on.
If the windshield fogs up, set the mode to the or position.
Operation Tips
To keep dust or unpleasant fumesfrom 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 airposition when the dust or odor has
dissipated 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 theair conditioning system, and adjust
the temperature control to desired
temperature.
Air conditioning
HYUNDAI Air Conditioning Systems
are filled with R-134a refrigerant.
1. Start hybrid system. Push the air conditioning button.
2. Set the mode to the position.
3. Set the air intake control to the out- side air or recirculated air position.
4. Adjust the fan speed control and temperature control to maintain
maximum comfort.
The refrigerant system should only be serviced by trained and
certified technicians to insure
proper and safe operation.
The refrigerant system should be serviced in a well-ventilated
place.
The air conditioning evaporator (cooling coil) shall never berepaired or replaced with one
removed from a used or sal-
vaged vehicle and new replace-
ment MAC evaporators shall be
certified (and labeled) as meet-
ing SAE Standard J2842.

Information
 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
overheating. Continue to use the
blower fan but turn the air condi-
tioning system off if the temperature
gauge indicates 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 elec-
trical 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.
Use air conditioning to reduce humidity and moisture inside the
vehicle on rainy or humid days.
During air conditioning system operation, you may occasionallynotice a slight change in enginespeed 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.
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.

System maintenance
Climate control air filter
The climate control air filter installed
behind the glove box filters the dustor other pollutants that come into the
vehicle from the outside through theheating 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, we recommend that the cli-
mate control air filter be replaced by
an authorized HYUNDAI dealer.Information
 Replace the filter according to the Maintenance Schedule.
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 suddenly decreases, we recommend that the
system be checked by 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 alsohas a bad influence on the air condi-tioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by an authorized
HYUNDAI dealer.

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 thatthe correct type and amount of
oil and refrigerant is used.
Otherwise, it may cause damage
to the vehicle and personal injury.
