Hyundai Sonata: 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 has a negative influence on the air conditioning 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.
WARNING
The air conditioning system should be serviced by an authorized HYUNDAI dealer. Improper service may cause serious injury to the person performing the service.
