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 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.  
[A] : Outside air, [B] : Recirculated air  
[C] : Climate control air filter, [D] : Blower  
[E] : Evaporator core, [F] : Heater core  
This 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.  
We recommend that the climate control  
air filter be replaced by a HYUNDAI  
authorised repairer 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.  
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 the air flow rate suddenly decreases,  
we recommend the system be checked  
at a HYUNDAI authorised repairer.  
All refrigerants should be reclaimed  
with proper equipment.  
Venting refrigerants directly to the  
atmosphere is harmful to individuals
