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

ON position could cause the bat-
tery to discharge. Operate the fan
speed when hybrid system is run-
ning.

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

Air conditioning
HYUNDAI Air Conditioning Systems
are filled with R-134a refrigerant.
1. Start hybrid system. Push the airconditioning 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 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 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.
