Information
Prolonged operation of the heater in
the recirculated air position (without
air conditioning selected) may cause
fogging of the windshield and side win-
dows and the air within the passenger
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 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 seri-
ous harm or death due to a
drop in the oxygen level
and/or body temperature.
Continued climate control sys-
tem operation in the recirculat-
ed 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.

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 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 the
air 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 be
repaired 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 in
direct 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 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.
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 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, 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 also
has 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.

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

For maximum windshield defrost-
ing, set the temperature control
knob to the highest temperature
setting and the fan control knob to
the highest fan speed. Select the
front defrost button on the climate
control display. After the engine
warm-up period, warm air will be
directed to the front windshield.
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 win-
dow, outside rear view mirrors, and
all side windows.
Clear all snow and ice from the
hood and air inlet in the cowl grill to
improve heater and defroster effi-
ciency and to reduce the probability
of fogging up the inside of the wind-
shield.
To reduce tendency of the glass
fogging and also to improve visibil-
ity, keep the interior surface of the
windshield clean by wiping it with a
clean cloth and glass cleaner.If the engine temperature is still
cold after starting, then a brief
engine warm up period may be
required for the vented air flow to
become warm or hot.NOTICE
Windshield heating
Do not use the or posi-
tion during cooling operation in
extremely humid weather. The
difference between the temper-
ature of the outside air and that
of the windshield could cause
the outer surface of the wind-
shield to fog up, causing loss of
visibility could cause an acci-
dent resulting in serious injury
or death. In this case, set the
mode selection knob or button
to the position and fan
speed control knob or button to
a lower speed.
