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.
