What is the ON button?

"ON" is the power-on button, and "OFF" is the power-off button. ON and OFF are very common buttons. You can find them on the car light lever, where ON means turn on and OFF means turn off. Below is a related introduction to other functional buttons in cars: 1. The "SEL" button is the menu selection confirmation button, usually located on the multifunction steering wheel. 2. The "OK" button has the exact same function as the "SEL" button. Some cars use "SEL," while others use "OK." 3. The "A/C" button is the compressor switch, short for Air-Condition, which is the air conditioning cooling switch. This is because car air conditioning heating does not require the compressor. 4. "VOL+/-" are the volume adjustment buttons. VOL is the abbreviation of the word "volume," meaning sound level, and it can adjust the volume of the car audio. 5. "MUTE" is the mute button, which can mute the sound with one click. 6. "MODE" is the mode-switching button. 7. "SET" on the multifunction steering wheel is the cruise control function button.
The 'ON' button for the car air conditioner is essentially the master switch that activates the entire system. Pressing it powers up the AC, and it starts operating according to your preset temperature and fan speed settings (though manual adjustments are still possible). Personally, whether it's sweltering heat or freezing winter, I habitually hit 'ON' upon entering the car—it's more convenient than manually twisting temperature dials. Note: After startup, there might be brief noise before stabilization. For optimal comfort, combine with 'AUTO' mode—first press 'ON', then engage 'AUTO' for intelligent temperature control. Always remember to press 'OFF' when done to prevent battery drain. Older vehicles may lack a dedicated 'ON' button, but turning the knob to a certain position often serves the same purpose—familiarize yourself with your car's control layout to avoid distractions while driving.
I always love using the 'ON' button for the car AC. When it's hot, pressing it immediately blows cool air – simple and straightforward without overthinking. Initially unfamiliar, I'd randomly press other buttons, but 'ON' is the master switch activating the whole system. After that, you can adjust fan speed or set it to auto for smart operation. I remember when I first got the car, I tried just turning the temperature dial without pressing 'ON' – the AC didn’t respond. You must ensure it’s turned on first. After shutting off and restarting the engine, the AC defaults to off; pressing 'ON' reactivates it. Over time, I learned that regular AC filter checks paired with the 'ON' button improve efficiency—otherwise, dust buildup affects airflow. For safe driving, don’t get distracted searching for the button due to weak airflow.
