Air conditioning
Your HYUNDAI vehicle air condition- ing system is filled with R-1234yf
refrigerant.
1. Start the vehicle.
2. Press the air conditioning button.
3. Select the Face Level mode.
4. Set the air intake control toRecirculation mode temporarily to
allow the cabin to cool quickly.
When the desired temperature inthe cabin is reached, change the
air intake control back to Fresh
mode.
5. Adjust the fan speed control and temperature control to maintain
maximum comfort.
When maximum cooling is desired,
set the temperature control to the
MAX A/C position, then set the fanspeed control to the highest setting. When using the air conditioning
system, monitor the temperature
gauge closely while driving up
hills or in heavy traffic when out-
side temperatures. Air condition-
ing system operation when climb-ing a steep grade or in high out-side ambient temperatures can
cause fuel cell stack overheating.
Continue to use the fan, but turn the air conditioning system off if
the temperature gauge indicates
fuel cell stack overheating.
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.
After sufficient cooling has been achieved, switch back from recircu-
lation mode to fresh mode. To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the airconditioning system with the win-
dows and sunroof closed.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance.
If you operate air conditioner exces- sively, the difference between the
temperature of the outside air andthat 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 control to the lowerspeed.

System Maintenance
Cabin air filter
[A] : Outside air, [B] : Recirculated air
[C] : Climate control air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core The cabin air filter is installed behind
the glove box. It filters the dust or other
pollutants that enter the vehiclethrough the heating and air condition-ing system.
Have the The cabin air filter replaced
by an authorized HYUNDAI dealeraccording to the maintenance sched-
ule.If the vehicle is being driven in
severe conditions such as dusty or
rough roads and/or if transporting
pets or occupants smoke inside the
vehicle, then more frequent cabin airfilter inspections and changes arerequired.
If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized HYUNDAI dealer.
Checking the amount of air con-
ditioner refrigerant and com-
pressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
reduces the performance of the airconditioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by an authorized
HYUNDAI dealer.
It is important that the correct type and amount of oil and refrig-
erant is used. Otherwise, damageto the compressor and abnormal
system operation may occur. To
prevent damage, the air condition-
ing system in your vehicle should
only be serviced by trained and
certified technicians.

7. Service manual
Vehicles equipped with R-1234yf
Since the refrigerant is
mildly flammable andoperated at high pres-
sure, the air condition-
ing system should only
be serviced by trained
and certified techni-
cians. It is important
that the correct type and amount
of oil and refrigerant are used.
All refrigerants should be
reclaimed with proper equipment.
Venting refrigerants directly to the atmosphere is harmful to individu-
als and environment. Failure toheed these warnings can lead toserious injuries.
