Hyundai Kona: System maintenance / Checking the amount of air conditioner refrigerant and compressor lubricant

Hyundai Kona (OS) 2018-2021 Owners Manual / Convenient features of your vehicle / Manual climate control system / 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.

Because the refrigerant is at very 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 is used. Otherwise, it may cause damage to the vehicle and personal injury.
