Air intake control
The air intake control is used to select the outside (fresh) air position or recircu-lated air position.
To change the air intake control position,
press the control button.Recirculated air position
With the recirculated airposition selected, air from
the passenger compart-
ment will be drawn throughthe heating system andheated 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 orcooled according to thefunction selected.
✽✽NOTICE
Prolonged operation of the heater in the
recirculated air position (without air
conditioning selected) may cause fogging
of the windscreen and side windows and
the air within the passenger compart-
ment 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
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 controlto the outside (fresh) air position
as much as possible whilst driv-ing.

Operation Tips
To keep dust or unpleasant fumes fromentering 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 windscreen. Care should be
taken that these are not blocked by
leaves, snow, ice or other obstructions.
To prevent interior fog on the wind- screen, 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
All HYUNDAI Air Conditioning Systems
are filled with environmentally friendly
R-134a refrigerant which does not dam-
age the ozone layer.
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 extremeleft position, set the mode control to
the MAX A/C position, then set the fanspeed control to the highest speed.✽✽ NOTICE
 When using the air conditioning sys- tem, monitor the temperature gauge
closely whilst 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 conditioningsystem.
During air conditioning system opera- tion, you may occasionally notice aslight 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 ofthe windscreen could cause the outer
surface of the windscreen 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 windscreen even when the outside
(fresh) air position is selected. If this hap-
pens, have the climate control air filter
replaced by an authorised HYUNDAI
dealer.
