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.
After sufficient cooling has been achieved, switch back from recir-
culation 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 air
conditioning 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 excessively, the difference
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 to the lower
speed.
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 vehicle
through the heating and air condi-
tioning system. Have the cabin air filter replaced by
an authorized HYUNDAI dealer
according 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 air
filter inspections and changes are
required.
If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized HYUNDAI dealer.

When using the air conditioning
system, monitor the engine tem-
perature gauge closely while driv-
ing up hills or in heavy traffic
when outside temperatures are
high. Air conditioning system
operation when climbing a steep
grade or in high outside ambient
temperatures can cause engine
overheating. Continue to use the
fan, but turn the air conditioning
system off if the engine tempera-
ture gauge indicates engine over-
heating.

trolled automatically according to
certain conditions such as or
positions. To cancel or reset the
defogging logic, do the following.
Manual climate control system
1. Turn the ignition switch to the ONposition.
2. Press the defroster button ( ).
3. Press the air intake control button at least 5 times within 3 seconds.
The LED indicator on the air intake
button will blink 3 times to indicate
that the defogging logic has been
disabled.
Repeat the steps again to re-enable
the defogging logic.
If the battery has been discharged or
disconnected, it resets to the defog
logic status.
Automatic climate control system
1. Turn the ignition switch to the ON position.
2. Press the defroster button ( ).
3. While pressing the air conditioning button (A/C), press the air intake
control button at least 5 times
within 3 seconds.
The Automatic Climate Control infor-
mation screen will blink 3 times to
indicate that the defogging logic has
been disabled.
Repeat the steps again to re-enable
the defogging logic.
If the battery has been discharged or
disconnected, it resets to the defog
logic status.
Auto Defogging System
(Additional Feature with
Automatic Temperature
Control System) (if equipped)
Auto defogging helps reduce the pos-
sibility of fogging up the inside of the
windshield by automatically sensing
the moisture on inside the windshield.
The auto defogging system operates
when the heater or air conditioning is
on.
Information
The auto defogging system may not
operate normally, when the outside
temperature is below 14 °F (-10 °C).
