Fan speed control
The fan speed can be set as desired
by turning the fan speed control
knob.
More air is delivered with higher fan
speeds.
Pressing the OFF button turns off the
fan.
Information
For better sound quality, fan speed
may automatically slow down for a
couple of minutes when you activate
voice recognition or hands free.
Operating the fan when the igni-
tion switch is in the ON position
could cause the battery to dis-
charge. Operate the fan when the
engine is running.
NOTICE
i
OYC046317
Continued use of the climate
control system operation in
the recirculated air position
can cause drowsiness or
sleepiness, that may cause
loss of vehicle control result-
ing in an accident. Set the air
intake control to the outside
(fresh) air position as much as
possible while driving.
Continued use of the climate
control system operation in
the recirculated air position
(without the air conditioning
selected) 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 injury or death due to a
drop in the oxygen level
and/or body temperature.

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 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 lower speed.System Maintenance
Climate control 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 driv-
en in severe conditions such as
dusty or rough roads, more frequent
air conditioner filter inspections and
changes are required.
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 air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized HYUNDAI dealer.
It is important that the correct
type and amount of oil and refrig-
erant is used. Otherwise, damage
to 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.

For maximum defrosting, set the
temperature control to the extreme
right/hot position and the fan speed
control to the highest speed.
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, side 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.
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.Manual Climate Control System
To defog inside windshield
1. Select any fan speed except "0"
position.
2. Select the desired temperature.
3. Select the or position.
4. The outside (fresh) air will be select-
ed automatically. Additionally, the air
conditioning will automatically oper-
ate if the mode is selected to the
position.
If the air conditioning and outside
(fresh) air position are not selected
automatically, press the correspon-
ding button manually.

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.

Auto Defogging System
(Only for Automatic Climate
Control System, if equipped)
Auto defogging reduces the possibil-
ity of fogging up the inside of the
windshield by automatically sensing
the moisture on inside the wind-
shield.
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 50 °F (-10 °C).When the Auto Defogging
System operates, the indi-
cator will illuminate.
If high levels of moisture are sensed in
the vehicle, the Auto Defogging System
will operate in the following order:
Step 1: Outside air position
Step 2:Operating the air conditioning
Step 3: Blowing air toward the wind-
shield
Step 4: Increasing air flow toward the
windshield
If the air conditioning is off or recircu-
lated air position is manually selected
while Auto Defogging System is ON,
the Auto Defogging System Indicator
will blink 3 times to signal that the
manual operation has been canceled.
To cancel or reset the
Auto Defogging System
Press the front windshield defroster
button for 3 seconds when the ignition
switch is in the ON position. When the
Auto Defogging System is canceled,
the ADS OFF symbol will blink 3 times
and ADS OFF will be displayed on the
climate control information screen.When the Auto Defogging System is
reset, the ADS OFF symbol will blink
6 times without a signal.
Information
• When the air conditioning is turned
on by Auto defogging system, if you
try to turn off the air conditioning, the
indicator will blink 3 times and the air
conditioning will not be turned off.
• For efficiency, do not select recircu-
lated air position while the Auto
defogging system is operating.
• When Auto defogging mode is
selected, fan speed, temperature and
intake mode which is adjusted man-
ually are canceled for better defog-
ging result.
Do not remove the sensor cover
located on the upper end of the
windshield glass.
Damage to system parts could
occur and may not be covered by
your vehicle warranty.

Rear Window Defroster
To prevent damage to the conduc-
tors bonded to the inside surface
of the rear window, never use
sharp instruments or window
cleaners containing abrasives to
clean the window.
If you want to defrost and defog
the front windshield, refer to the
"Windshield Defrosting and
Defogging" section in this chapter.
The defroster heats the window to
remove frost, fog and thin ice from
the interior and exterior of the rear
window, while the engine is running. To activate the rear window
defroster, press the rear window
defroster button located in the center
facia switch panel. The indicator on
the rear window defroster button illu-
minates when the defroster is ON.
To turn off the defroster, press the
rear window defroster button again.
Information
• If there is heavy accumulation of
snow on the rear window, brush it off
before operating the rear defroster.
• The rear window defroster automat-
ically turns off after approximately
20 minutes or when the ignition
switch is in the LOCK/OFF position.
Side view mirror defroster
If your vehicle is equipped with the
side view mirror defrosters, they will
operate at the same time you turn on
the rear window defroster.
