Checking the amount of air

conditioner refrigerant and

compressor lubricant

System maintenance

Climate control air filter

When the amount of refrigerant is low,

the performance of the air conditioning

is reduced. Overfilling also has a bad

influence on the air conditioning system.

Therefore, if abnormal operation is

found, we recommend that the system

be inspected by a HYUNDAI authorised

repairer.

NOTICE

OIK047401L

It is important that the correct type and

amount of oil and refrigerant are 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.

[A] : Outside air, [B] : Recirculated air

[C] : Climate control air filter, [D] : Blower

[E] : Evaporator core, [F] : Heater core

The climate control air filter installed

behind the glove box filters the dust

or other pollutants that come into the

vehicle from the outside through the

heating and air conditioning system. If

dust or other pollutants accumulate in

the filter over a period of time, the air

flow from the air vents may decrease,

resulting in moisture accumulation

on the inside of the windscreen even

when the outside (fresh) air position is

selected.

WARNING

Vehicles equipped with R-134a

Since the refrigerant is

operated at very high

pressure, the air

conditioning system should

only be serviced by trained

and certified technicians.

If this happens, we recommend that the

climate control air filter be replaced by a

HYUNDAI authorised repairer.

All refrigerants should be reclaimed

with proper equipment.

Venting refrigerants directly to the

atmosphere is harmful to individuals
