Air intake control
This is used to select the outside (fresh)
air position or recirculated air position.
To change the air intake control position,
push the control button.Recirculated air position
With the recirculated airposition selected, air from
the passenger compart-
ment will be drawn through
the heating system and
heated or cooled according
to the function selected.
Outside (fresh) air position With the outside (fresh) airposition selected, air
enters the vehicle from out-
side and is heated or
cooled according to the
function selected.
✽ ✽ NOTICE
Prolonged operation of the heater in the
recirculated air position (without air
conditioning selected) may cause fog-
ging of the windshield and side windows
and the air within the passenger com-
partment may become stale.
In addition, prolonged use of the air con-
ditioning with the recirculated air posi-
tion selected will result in excessively dry
air in the passenger compartment.

WARNING
The continuous use of recirculat-ed air in the climate control sys-
tem may increase humidity inside
the vehicle, causing the glass to
fog and obscuring visibility.
Do not sleep in a vehicle with the air conditioning or heating sys-
tem on. It may cause serious
harm or death due to a drop in the
oxygen level and/or body temper-
ature.
The continuous use of recirculat- ed air in the climate control sys-
tem can produce drowsiness or
sleepiness, which may result in a
loss of vehicle control. Set the air
intake control to the outside
(fresh) air position as much as
possible while driving.

Operation Tips
To keep dust or unpleasant fumes from
entering the vehicle through the venti-
lation system, temporarily set the air
intake control to the recirculated air
position. Be sure to return the control
to the fresh air position when the irrita-
tion has passed to keep fresh air in the
vehicle. This will help keep the driver
alert and comfortable.
Air for the heating/cooling system is drawn in through the grilles just ahead
of the windshield. Care should be
taken that these are not blocked by
leaves, snow, ice or other obstructions.
To prevent interior fog on the wind- shield, set the air intake control to the
fresh air position and fan speed to the
desired position, turn on the air condi-
tioning system, and adjust the temper-
ature control to desired temperature.Air conditioning (if equipped)
All HYUNDAI Air Conditioning Systems
are filled with environmentally friendly
R-134a refrigerant which does not dam-
age to the ozone layer.
1. Start the engine. Push the air condi- tioning button.
2. Set the mode to the position.
3. Set the air intake control to the outside air or recirculated air position.
4. Adjust the fan speed control and tem- perature control to maintain maximum
comfort.✽ ✽NOTICE
• When using the air conditioning sys-
tem, monitor the temperature gauge
closely while driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine over-
heating. Continue to use the blower
fan but turn the air conditioning sys-
tem off if the temperature gauge indi-
cates engine overheating.
• When opening the windows in humid weather air conditioning may create
water droplets inside the vehicle.
Since excessive water droplets may
cause damage to electrical equipment,
air conditioning should only be used
with the windows closed.

Features of your vehicle
Air conditioning system operation tips
If the vehicle has been parked in directsunlight during hot weather, open the
windows for a short time to let the hot
air inside the vehicle escape.
Use air conditioning to reduce humidi- ty and moisture inside the vehicle on
rainy or humid days.
During air conditioning system opera- tion, you may occasionally notice a
slight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
Use the air conditioning system every month only for a few minutes to ensure
maximum system performance. When using the air conditioning sys-
tem, you may notice clear water drip-
ping (or even puddling) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic.
Operating the air conditioning system in the recirculated air position provides
maximum cooling, however, continual
operation in this mode may cause the
air inside the vehicle to become stale.
During cooling operation, you may occasionally notice a misty air flow
because of rapid cooling and humid air
intake. This is a normal system opera-
tion characteristic.
Climate control air filter
(if equipped)
The climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the vehi-
cle from the outside through the heating
and air conditioning system. If dust or
other pollutants accumulate in the filter
over a period of time, the air flow from the
air vents may decrease, resulting in
moisture accumulation on the inside of
the windshield even when the outside
(fresh) air position is selected. If this hap-
pens, have the climate control air filter
replaced by an authorized HYUNDAI
dealer.

✽
✽
NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the car is being driven in severe
conditions such as dusty, rough roads,
more frequent climate control air fil-
ter inspections and changes are
required.
• When the air flow rate suddenly decreases, the system should be
checked at an authorized HYUNDAI
dealer.
Checking the amount of air con-
ditioner refrigerant and compres-
sor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a bad influ-
ence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.
✽ ✽ NOTICE
It is important when servicing the air
conditioning system that the correct
type and amount of oil and refrigerant is
used. Otherwise, damage to the com-
pressor and abnormal system operation
may occur.
WARNING
The air conditioning system should
be serviced by an authorized
HYUNDAI dealer. Improper service
may cause serious injury to the
person performing the service.

For maximum defrosting, set the tem-perature control to the hottest position
and the fan speed control to the high-
est 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, out-
side rear view mirrors, and all side win-
dows.
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.
Manual climate control system
To defog inside windshield
1. Set the fan speed to the desired posi- tion.
2. Select desired temperature.
3. Select the position.
4. The outside (fresh) air will be selected automatically. If the position is
selected, air conditioning (if equipped)
will also be selected automatically.
If the air conditioning and/or outside
(fresh) air position are not selected auto-
matically, press the corresponding button
manually.
WINDSHIELD DEFROSTING AND DEFOGGING
WARNING- Windshield heating
Do not use the position during
cooling operation in extremely
humid weather. The difference
between the temperature of the out-
side air and the windshield could
cause the outer surface of the
windshield to fog up, causing loss
of visibility. In this case, set the
mode selection to the position
and fan speed control to the lower
speed.

Features of your vehicle
Auto defogging system (Only for automatic climate controlsystem, 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 AUTO mode is on. This indicator illuminates
when the auto defogging
system senses the moisture
of inside the windshield and
operates.
If more moisture is in the vehicle, higher
steps operate as follow.
Step 1 : Operating the air conditioning
Step 2 : Outside air position
Step 3 : Blowing air flow toward the wind- shield
Step 4 : Increasing air flow toward the windshield
If your vehicle is equipped with the auto
defogging system, it is automatically acti-
vated when the conditions are met.
However, if you would like to cancel the
auto defogging system, press the front
defroster button 4 times within 2 seconds
while pressing the AUTO button. The
indicator will blink 3 times to notify you
that the system is cancelled. To use the
auto defogging system again, follow the
procedures mentioned above.
If the battery has been disconnected or
discharged, it resets to the auto defog-
ging status.
✽ ✽ NOTICE
If the A/C off is manually selected while
the auto defogging system is on, the auto
defogging indicator will blink 3 times to
give notice that the A/C off can not be
selected.
