The cabin air filter is installed behind the glove box. It filters the dust or other pollutants that enter the vehicle through the heating and air conditioning system.

We recommend that the climate control air filter be replaced by an authorised HYUNDAI dealer according to the maintenance schedule. If the vehicle is being driven in severe conditions such as dusty or rough roads, more frequent climate control filter inspections and changes are required.

  • Replace the filter according to the maintenance schedule. If the car is being driven in severe conditions such as dusty, rough roads, more frequent climate control air filter inspections and changes are required.

  • When the air flow rate suddenly decreases, we recommend that your vehicle be inspected by an authorised HYUNDAI dealer.

Checking the amount of air conditioner refrigerant

If the amount of refrigerant is too low or too high, the performance of the air conditioning is reduced. We recommend that your vehicle be inspected by an authorised HYUNDAI dealer.

  • The refrigerant system should only be serviced by trained and certified technicians in a well-ventilated area to ensure proper and safe operation.

  • Never repair the air conditioning evaporator (cooling coil) or replace with the one removed from a used or salvaged vehicle. A new replacement evaporator must be certified (and labeled) as meeting SAE Standard as labeled.

To prevent serious injury, have the air conditioning system be serviced by only trained and certified technicians. R-134a is operated at high pressure.

Reclaim all refrigerants with proper equipment. Venting refrigerants directly to the atmosphere is harmful to individuals and environment.
