Checking Air Conditioner Refrigerant Quantity and Compressor Lubricant
When the refrigerant quantity is low, air conditioner performance is reduced. Overfilling also adversely affects the air conditioning system. Therefore, if abnormal operation is detected, have the system inspected by a professional workshop.
Kia recommends visiting an authorized Kia dealer/service partner.
