Convenience Features5-106
Information
Using the system in the fresh air position is
recommended.
Prolonged operation of the heater in the
recirculated air position (without air
conditioning selected) can cause fogging 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 recirculated air
position selected will result in excessively
dry air in the passenger compartment.
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 air
conditioning or heating system on. It
may cause serious harm or death due
to a drop in the oxygen level and/or
body temperature.
• 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
to the outside (fresh) air position as
much as possible while driving.

If you press the DRIVER ONLY button
and the indicator light illuminates, air
mostly blows in the direction of the
driver’s seat.
However, some of the air may come out
of other seating position ducts to keep
indoor air pleasant.
Using the DRIVER ONLY button is a
convenient feature when there are no
other passengers in the vehicle and helps
to reduce energy consumption from the
climate control system.
When the front windshield defroster
button is pressed to remove frost, air
blows from the left and right sides of
the front windshield even if the DRIVER
ONLY button has been pressed.

NOTICE
When using the air conditioning system,
monitor the temperature gauge closely
while driving up hills or in heavy traffic
when outside temperatures are high.
Air conditioning system operation may
cause engine overheating. Continue to
use the fan but turn the air conditioning
system off if the temperature gauge
indicates engine overheating. Air conditioning system operation tips
• If the vehicle has been parked in
dir
ect sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
• After sufficient cooling has been achieved, switch back from the
recirculated air to the fresh outside air
position.
• To help reduce moisture inside of the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the windows
and sunroof closed.
• Use the air conditioning system every month for a few minutes to ensure
maximum system performance.
• If you operate the air conditioner excessively, the difference between
the temperature 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 button to
the
position and set the fan speed
control knob to the lowest speed
setting.

System Maintenance
Cabin air filter
OIK047401LOIK047401L[A] : Outside air, [B] : Recirculated air
[C] : Cabin air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
The cabin air 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 cabin air filter replaced by an
authorized HYUNDAI dealer according to
the maintenance schedule. If the vehicle
is being driven in severe conditions such
as dusty or rough roads, more frequent
climate control filter inspections and
changes are required.
If the air flow rate suddenly decreases,
the system should be checked at an
authorized HYUNDAI dealer.
Air Conditioning Performance and
Maintenance at Your HYUNDAI
Dealer
When the amount of refrigerant is low,
the performance of the air conditioning
is reduced. Overfilling also reduces the
performance of 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. To prevent damage, the air
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.
NOTICE
• The refrigerant system should only
be serviced by trained and certified
technicians to insure proper and safe
operation.
• The refrigerant system should be
serviced in a well-ventilated place.
• The air conditioning evaporator
(cooling coil) shall never be repaired
or replaced with one removed from
a used or salvaged vehicle and new
replacement MAC evaporators shall
be certified (and labeled) as meeting
SAE Standard J2842.
