Cabin air filter
OIK047401L[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 be 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,
have the system be checked at an
authorized HYUNDAI dealer.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
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 be 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.
WARNING
Vehicles equipped with R-1234yf
Since the refrigerant is
mildly flammable and
operated at high pressure,
the air conditioning system
should only be serviced
by trained and certified
technicians. It is important
that the correct type and
amount of oil and refrigerant
are used.
All refrigerants should be reclaimed
with proper equipment.
Venting refrigerants directly to the
atmosphere is harmful to individuals
and environment. Failure to heed these
warnings can lead to serious injuries.

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 outside air and that
of the windshield could cause the outer
surface of the windshield to fog up,
causing loss of visibility could cause
an accident resulting in serious injury
or death. In this case, set the mode
selection button to the
position
and fan speed control knob to a lower
speed.

[ For maximum defrost performance,
set the temperature control to the
highest temperature setting and
the fan speed control to the highest
setting.

[ 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,
side view mirrors, and all side
windows.

[ 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.
NOTICE
If the engine temperature is still cold
after starting, then a brief engine warm
up period may be required for the
vented air flow to become warm or hot.

Auto defogging system (only
for automatic climate control
system, if equipped)
Auto defogging help reduce the
possibility of fogging up the inside of the
windshield by automatically sensing the
moisture on inside the windshield.
The auto defogging system operates
when the heater or air conditioning is on.
Information
The auto defogging system may not
operate normally, when the outside
temperature is below 14°F(-10°C).
To cancel or set the Auto Defogging
System, keep the front defroster button
pressed for 3 seconds. The “ADS OFF”
symbol will be shown in the climate
display to inform you that the system
is deactivated. To re-activate the auto
defogging system, follow the procedure
