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 retailer of 
Genesis Branded products.
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-134a
Since the refrigerant is 
operated at very high 
pressure, the air c
onditioning 
system should only be 
serviced by trained and 
certified technicians.
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.
 WARNING
Vehicles equipped with R-1234yf
Since the refrigerant is mildly 
flammable and operated 
at high pressur
e, 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.
• 
Check the coolant level when 
the motor compartment 
is cooled. Coolant le
vel is 
influenced by temperature, 
and if the coolant reservoir 
cap is removed when coolant 
temperature is high, hot 
coolant and steam may blow 
out under pressure causing 
serious injury.
•  Make sure the coolant cap is properly 
closed after refilling coolant. 
Otherwise the motor could be 
overheated while driving.
