Checking the efficiency of the air conditioner
Start the engine and let it run at high idle with the A/C set to maximum cooling.
If the air escaping from the vents in the instrument panel is not cold, have the vehicle checked by an authorized Hyundai dealer for the air conditioning system to be checked.
Attention! Operating the air conditioner for a long period of time with low refrigerant levels may damage the compressor.
Lubricant
To lubricate the compressor and seals of the air conditioning system, it is necessary to run the air conditioner for at least 10 minutes every week. This is especially important during cold weather when the air conditioning system is not in use.
