System operation
Ventilation
1. Set the mode to the position.
2. Set the air intake control to the outside(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 the outside(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
,position. Operation Tips
To prevent 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 out-
side smell or dust has passed, to keep
fresh air in the vehicle.
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 the temper-
ature control to desired temperature.
Air conditioning
HYUNDAI Air Conditioning Systems are
filled with environmentally friendly
R-134a refrigerant.
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 recir- culated air position. However, pro-
longed operation of the recirculated air
position will excessively dry the air. In
this case, change the 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 then set the fan speed
control to the highest speed.

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 the air conditioning
operates 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 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 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 the air conditioner excessively, the difference between the
temperature 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.

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 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 lubricant
When 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.
✽ ✽ NOTICE
It 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. OMG075033

WARNING
The air conditioning system for the
Hybrid vehicle should be serviced
by an authorized HYUNDAI dealer.
The Hybrid air conditioning system
is connected to the high voltage
system and requires special fluids,
tools and service procedures.
Improperly servicing the Hybrid air
conditioning system could result in
electrical shock, serious injury, or
even death.

WINDSHIELD DEFROSTING AND DEFOGGING
For maximum defrosting, set the tem-perature control to the extreme
right/hot position and the fan speed
control to the highest speed.
If warm air to the floor is desired while defrosting or defogging, set the mode
to the floor-defrost position.
Before driving, clear all snow and ice from the windshield, rear window, out-
side rear view mirrors, and all side win-
dows.
Clear all snow and ice from the hood and air inlet in the cowl grill to improve
heater and defroster efficiency and to
reduce the probability of fogging up the
inside of the windshield.
Automatic climate control system
To defog inside windshield
1. Select desired fan speed.
2. Select desired temperature.
3. Press the defrost button ( ).
4. The outside (fresh) air position will be selected automatically.
If the outside (fresh) air position is not
selected automatically, adjust the corre-
sponding button manually.
If the position is selected, lower fan
speed is adjusted to a higher fan speed.

WARNING- Windshield heating
Do not use the or position
during cooling operation in
extremely humid weather. The dif-
ference 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 knob or button to
a lower speed.

To defrost outside windshield
1. Set the fan speed to the highest(extreme right) position.
2. Set the temperature to the extreme hot (HI) position.
3. Press the defrost button ( ).
4. The outside (fresh) air position will be selected automatically.
If the position is selected, lower fan
speed is adjusted to a higher fan speed.
Defogging logic
To reduce the probability of fogging up
the inside of the windshield, the air intake
is controlled automatically according to
certain conditions such as or
position. To cancel or return the defog-
ging logic, perform the following steps.
