WARNING
• Continued climate control system
operation 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

tem on. It may cause serious
harm or death due to a drop in the
oxygen level and/or body temper-
ature.
• Continued climate control system
operation in the recirculated air
position can cause drowsiness or
sleepiness, and loss of vehicle
control. Set the air intake control

them from entering the vehicle, however,
unpleasant or foul odors that might be
present may still be noticeable within the
vehicle.Exhaust gas cutoff mode :
Air enters the vehicle from the outside.
If exhaust gas enters the vehicle from the
outside, the exhaust gas cutoff mode is
automatically converted from the outside
air position to the recirculated air position
to prevent exhaust gas from entering the
vehicle.
✽NOTICE
It should be noted that prolonged oper-
ation of the heating system in recircula-
tion mode will give rise to misting of the
windshield and side windows and the air
within the passenger compartment will
become stale. In addition, prolonged use
of the air conditioning with the recircu-
lation mode selected may result in the
air within the passenger compartment
becoming excessively dry.

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.
✽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 run
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 characteristics.

Auto defogging system (if equipped)
Auto defogging reduces the probability 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.
This indicator illuminates
when the auto defogging
system senses the moisture
of inside the windshield and
operates.If more moisture is in the vehicle, the
higher steps operate as follow. For exam-
ple if auto defogging does not defog
inside the windshield at step 1 Outside
air position, it tries to defog again at step
2 Blowing air toward the windshield.
Step 1 : Outside air position
Step 2 : Blowing air toward the wind-
shield
Step 3 : Increasing air flow toward the
windshield
Step 4 : Operating the air conditioning
