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 the
recirculated air to the fresh outside
air position.
• To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air con-
ditioning system with the windows
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 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
and fan speed control to the lower
speed.

System Maintenance

Climate control air filter

Climate control
Evaporator
air filter
This filter is installed behind the glove
box. It filters the dust or other pollu-
tants that enter the vehicle through the
heating and air conditioning system.
Have the climate control air filter be
replaced by an authorized HYUNDAI
dealer according to the maintenance
schedule. If the vehicle is being driven
in severe conditions such as dusty or
rough roads, more frequent air condi-
tioner filter inspections and changes
are required.
If the air flow rate suddenly decreas-
position
es, the system should be checked at
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
reduces the performance of the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized HYUNDAI dealer.
