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, we 
recommend that 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.
 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.
