How to Use the ECON Mode in Car Air Conditioning?
2 Answers
ECON in car air conditioning stands for Economy Mode. The air conditioning compressor is driven by the engine and can consume up to 20% of the engine's power. After activating the ECON mode, the vehicle will reduce the air conditioning power while ensuring its performance, thereby achieving fuel-saving effects. The ECON mode, also known as Economy Mode, is displayed as ECO mode in many car models. Pressing the ECON switch automatically puts the vehicle into a priority fuel-saving control mode. Enabling ECO mode is most effective in congested urban traffic. In such conditions, strong power is not necessary, and frequent stops and starts lead to higher fuel consumption. Activating ECO mode not only reduces fuel consumption but also makes driving more comfortable. There are a few situations where it is unnecessary to enable ECO mode: 1. When driving at high speeds (up to 100km/h), even if ECO is turned on, the vehicle's computer will prioritize speed, and the ECO mode will automatically deactivate. 2. When high torque output is required, such as when climbing hills, the engine computer will prioritize ensuring sufficient power to drive the vehicle, and the ECO mode will automatically deactivate.
I've been driving for several years and find the ECON mode super convenient. After turning on the air conditioning, I just press the ECON button on the center console. This mode automatically controls the compressor's operation to save fuel, making it especially suitable for city traffic jams. The fan speed is also reduced slightly. Although the cooling effect isn't as quick as in normal mode, it still feels quite cool in summer. I've noticed it saves a significant amount of fuel—using it for daily commutes can save me dozens of dollars a month. Don't worry about temperature settings; you can still adjust the temperature normally with the knob, but the system optimizes energy consumption more intelligently. If you press ECON after turning on the AC, it defaults to combining with the recirculation mode for better energy efficiency. Remember to check the cabin air filter regularly, as a dirty filter can increase power consumption. Long-term use reduces the engine's burden and lowers carbon emissions—killing multiple birds with one stone. Try it out in daily driving; don't dismiss it as uncomfortable from the start.
