Kia Sorento: Checking the amount of air conditioner (A/C) refrigerant and compressor lubricant - Climate control system - Controls and FeaturesKia Sorento: Checking the amount of air conditioner (A/C) refrigerant and compressor lubricant

Kia Sorento (MQ4, 2021-2026) Owner's Manual / Controls and Features / Climate control system / Checking the amount of air conditioner (A/C) refrigerant and compressor lubricant

Insufficient refrigerant levels within the system significantly reduce the overall cooling and heating performance of your Kia Sorento. Conversely, overfilling the refrigerant circuit also adversely impacts the high-pressure A/C system components and operational efficiency.

If any abnormal mechanical operation, unusual compressor noise, or loss of cooling capacity occurs, have the climate system thoroughly inspected by an authorized Kia dealer or certified specialist.

DANGER

The specialized oil and high-purity refrigerant circulating throughout your Kia Sorento vehicle’s advanced A/C system are maintained under extreme, high operating pressure. If proper factory service procedures, evacuation equipment, and safety protocols are not strictly followed, a sudden mechanical failure or explosion may result. To significantly reduce the risk of severe personal injury, permanent bodily harm, or death, the air conditioning system in your vehicle should exclusively be serviced by trained, licensed, and certified technicians.

NOTE

It is critically important that you utilize the exact chemical type and precise factory-specified amount of compressor oil and refrigerant. Using incompatible fluids or incorrect volumes may cause irreversible damage to internal climate components. To prevent costly equipment damage, the A/C system in your vehicle should only be handled by trained professionals.

WARNING

It is vital that you employ the correct grade and volume of lubricant and refrigerant during any maintenance cycle. Always safely reclaim all existing refrigerants using specialized, approved recovery equipment. Venting automotive refrigerants directly into the open atmosphere is severely harmful to individual human health and the surrounding environment. Failure to heed these essential safety warnings can lead to serious injuries.
