Refrigerant and Compressor Oil Quantity Check
If the refrigerant charge is too low, air conditioner performance is reduced. Overcharging the system also adversely affects the air conditioning system.
If any malfunctions are detected, do not attempt to repair them yourself; have them checked by a specialized workshop. Kia recommends visiting a Kia authorized dealer/service partner.
