Hyundai Azera: Climate control air filter

The climate control air filter installed behind the glove box filters the dust or other pollutants that come into the vehicle from the outside through the heating and air conditioning system.
If dust or other pollutants accumulate in the filter over a period of time, the air flow from the air vents may decrease, resulting in moisture accumulation on the inside of the windshield even when the outside (fresh) air position is selected. If this happens, have the climate control air filter replaced by an authorized HYUNDAI dealer.
✽ NOTICE
Checking the amount of air conditioner refrigerant and compressor lubricant
When the amount of refrigerant is low, the performance of the air conditioning is reduced. Overfilling also has a negative impact on the air conditioning system.
Therefore, if abnormal operation is found, have the system inspected by an authorized HYUNDAI dealer.
CAUTION - Compressor damage
It is important that the correct type and amount of oil and refrigerant is used. Otherwise, damage to the compressor and abnormal system operation may occur.
The air conditioning system should be serviced by an authorized HYUNDAI dealer.
