Hyundai i10/i20/i30 switch off the air conditioning permanently

Turn on the ignition (do not start the engine, the air conditioning is on), then press the upper air recirculation button 5 times in quick succession. The LED above the air recirculation button must flash 5 times.

The air conditioning is permanently switched off now.

Unfortunately, after a battery replacement or reset, this setting is deleted and must be carried out again.
