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
replaced by an authorized HYUNDAI
dealer according to the maintenance
schedule. If the car 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-
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.

Vehicles equipped with R-134a
Since the refrigerant
is operated at very
high pressure, the air
conditioning system
should only be serv-
iced by trained and certified
technicians.
All refrigerants should be
reclaimed with proper equip-
ment.
Venting refrigerants directly to
the atmosphere is harmful to
individuals and environment.
Failure to heed these warnings
can lead to serious injuries.

Auto Defogging System
Auto defogging system reduces the
possibility of fogging up the inside of
the windshield by automatically
sensing the moisture of 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 50 °F (10 °C).When the Auto Defogging
System operates, the indi-
cator will illuminate.
If higher level 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 select-
ed 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
POWER button is in the ON position.
When the Auto Defogging System is
canceled, ADS OFF symbol will blink
3 times and the ADS OFF will be dis-
played on the climate control infor-
mation screen.
When the Auto Defogging System is
reset, 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 Auto defog-
ging 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.
