Mode selection
The mode selection switch controls the
direction of the air flow through the venti-
lation system.
The air flow outlet port is converted as
follows:

Air flow is directed toward the upper body
and face. Additionally, each outlet can be
controlled to direct the air discharged
from the outlet.
Bi-Level (B, C, D, E, F)
Air flow is directed towards the face and
the floor.
Floor-Level (A, C, D, E)

✽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
conditioning with the recirculated air
position selected will result in excessive-
ly dry air in the passenger compart-
ment.
Fan speed control
The ignition switch must be in the ON
position for fan operation.
The fan speed control switch allows you
to control the fan speed of the air flowing
from the ventilation system.
To change the fan speed:
• Press the part of the switch for
higher fan speed.
• Press the part of the switch for
lower fan speed.

WARNING
• Continue using the climate con-
trol system in the recirculated air
position 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 sys-
tem on. It may cause serious
harm or death due to a drop in the
oxygen level and/or body temper-
ature.
• Continue using the climate con-
trol system in the recirculated air
position can cause drowsiness or
sleepiness, and loss of vehicle
control. Set the air intake control
to the outside (fresh) air position
as much as possible while driv-
ing.

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
HYUNDAI Air Conditioning Systems are
filled with environmentally friendly
R-134a refrigerant.
1. Start the engine. Press 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.
• When maximum cooling is desired, set
the temperature control to the extreme
left position, set the mode control to
the MAX A/C position, then set the fan
speed control to the highest speed.✽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.

Air conditioning system operation tips
• If the vehicle has been parked in direct
sunlight during hot weather, open the
windows for a short time to let the hot
air inside the vehicle escape.
• To help reduce moisture inside of the
windows on rainy or humid days,
decrease the humidity inside the vehi-
cle by operating the air conditioning
system.
• 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.
• If you operate air conditioner exces-
sively, the difference between the tem-
perature 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 con-
trol to the lower speed.
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 vehicle is being driven in severe
conditions such as dusty or rough
roads, more frequent air conditioner
filter 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 negative
impact on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.
✽NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
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.
