System Maintenance

Climate Control Air Filter

This filter is installed behind the glove box. It filters dust and other contaminants entering the vehicle through the heating and air conditioning system.

Hyundai recommends that the climate control air filter be replaced at an Authorized HYUNDAI Service Center according to the maintenance schedule. If the vehicle is operated under severe conditions such as dusty or rough roads, the climate control filter requires more frequent inspection and replacement.

If the airflow volume decreases significantly, we recommend having the system inspected at an Authorized HYUNDAI Service Center.

Inspecting the Air Conditioning Refrigerant Amount and Compressor Lubricant

When the refrigerant amount is low, air conditioning performance is reduced. Overcharging also reduces air conditioning system performance.

Therefore, if abnormal operation is found, we recommend that the system be inspected by an Authorized HYUNDAI repairer.

WARNING

Vehicles Equipped with R-134a

Because the refrigerant is under very high pressure, the air conditioning system must be serviced only by trained and certified technicians. It is important that the correct type and amount of oil and refrigerant are used. Otherwise, damage to the vehicle and personal injury may result.

WARNING

Vehicles equipped with R-1234yf

Because the refrigerant is highly flammable and under very high pressure, the air conditioning system must be serviced only by trained and certified technicians. It is important that the correct type and amount of oil and refrigerant are used. Otherwise, damage may result.

Air Conditioner Refrigerant Label

The actual air conditioner refrigerant label in the vehicle may differ from the illustration.

Each symbol and specification on the air conditioning refrigerant label has the meaning shown below:

1. Refrigerant classification
2. Refrigerant quantity
3. Compressor lubricant classification

You can find out which air conditioning refrigerant is used in your vehicle from the label located under the hood. Refer to Chapter 8 for the location of the air conditioning refrigerant label.
