Hyundai Kona: System maintenance / 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.
