Climate control air filter
OHI048581L
[A] : Outside air, [B] : Recirculated air
[C] : Climate control air filter, [D] : Blower
[E] : Evaporator core, [F] : PTC & Inner condenser
The cabin air filter is installed behind the
front trunk. 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
cabin air filter inspections and changes
are required.
If the air flow rate suddenly decreases,
have the system inspected 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 conditixoning
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.

Auto Defogging System
ONE1051072
Auto defogging helps reduce the
possibility of fogging up the inside of the
windshield by automatically sensing the
moisture on inside the windshield.
Information
The auto defogging system may not
operate normally, when the outside
temperature is below 14 °F (-10 °C).
When the Auto Defogging
System operates, the indicator
will illuminate.
If a high amount of humidity is detected
in the vehicle, the Auto Defogging
System will be enabled. The following
steps will be performed automatically:
Step 1) Air conditioning will turn ON.
Step 2) Air intake control will change to Fresh mode.
Step 3) Mode will change to defrost to direct airflow to the windshield.
Step 4) Fan speed will be set to MAX.
If the air conditioning is off or
recirculation mode is manually selected
while Auto Defogging System is ON, the
Auto Defogging System will be canceled.

Checking the Washer Fluid Level
ONE1091005
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. Plain
water may be used if washer fluid is not
available. However, use washer solvent
with antifreeze characteristics in cold
climates to prevent freezing.
WARNING
To prevent serious injury or death, take
the following safety precautions when
using washer fluid: • Do not use coolant or antifreeze in
the washer fluid reservoir. Coolant
can severely obscure visibility when
sprayed on the windshield and
may cause loss of vehicle control
resulting in an accident or damage to
paint and body trim.
• Do not allow sparks or flame to
contact the washer fluid or the
washer fluid reservoir. Washer fluid
may contain alcohol and can be flammable.
• Do not drink washer fluid and avoid
contact with skin. Washer fluid is
harmful to humans and animals.
• Keep washer fluid away from
children and animals.

reduction gear fluid
There is no reduction gear fluid level
gauge in the vehicle. Check the
reduction gear fluid every 60,000 km
regularly. If the vehicle is driven under
severe condition, check the maintenance
under severe usage condition and
consult an authorized HYUNDAI dealer.
