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.

Vehicles equipped with R-134a
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.
