System Maintenance
Climate control air filter
This filter is installed behind the glove
box. It filters the dust or other pollutants
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 conditioner filter
inspections and changes are required.
If the air flow rate suddenly decreases,
the system should be checked at an
authorized HYUNDAI dealer.
Checking the amount of air conditioner refrigerant andcompressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a negative
influence on 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 refrigerant is
used. Otherwise, damage to the com-
pressor and abnormal system opera-
tion may occur. The air conditioning system should be
serviced by an authorized HYUNDAI
dealer.

Air Conditioning refrigerantlabel
The actual Air Conditioning refrigerant
label in the vehicle may differ from the
illustration.
Each symbols and specification on air
conditioning refrigerant label means as
below :
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubricant
Refer to chapter 8 for more detail location
of the air conditioning refrigerant label. For maximum defrosting, set the tem-
perature 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 window, 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 efficiency and to
reduce the probability of fogging up the
inside of the windshield.
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.NOTICE

Windshield heating
Do not use the or position
during cooling operation in
extremely humid weather. The dif-
ference 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 could
cause an accident resulting in seri-
ous 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 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 oper-
ate normally, when the outside tempera-
ture is below 50 °F (-10 °C).When the Auto Defogging
System operates, the indica-
tor 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 : Blo wing air toward the wind-
shield
Step 4 : Increasing air flow toward the windshield
If the air conditioning is off or recirculated
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 but-
ton for 3 seconds when the ignition
switch 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 displayed on the cli-
mate control information 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 indica-
tor will blink 3 times and the air condi-
tioning will not be turned off.
• For efficiency, do not select recirculated air position while Auto defogging system
is operating.
• When Auto defogging mode is selected, fan speed, temperature and intake mode
which is adjusted manually are canceled
for better defogging result.
Do not remove the sensor cover locat-
ed on the upper end of the driver side
windshield glass.
Damage to system parts could occur
and may not be covered by your vehi-
cle warranty.
