Hyundai Kona (OS) 2018-2026 Owners Manual: 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.
