What does LO mean on the car air conditioner?
2 Answers
LO on the car air conditioner indicates the current lowest temperature setting. Here are some precautions for using the car air conditioner: 1. Regular dust removal: Periodically set the air conditioner to the maximum setting for about 10 minutes to effectively prevent dust accumulation. Alternatively, clean the air filter during car washing, and using an air conditioner cleaner can also be helpful. 2. Appropriate temperature: Normally, the temperature inside the car should be adjusted to around 26~27 degrees Celsius. 3. Mode switching: When first turning on the air conditioner, use the external circulation mode to lower the temperature inside the car, then switch to internal circulation. However, remember to alternate between these two modes periodically. 4. Check for leaks: It is essential to regularly check the engine hood and chassis for leaks. If exhaust fumes are detected inside the car, timely repairs should be carried out.
I've been driving for over a decade, and the LO setting on the AC is simply a temperature control level, meaning it's set to the coldest mode, equivalent to maximum cooling output. Turning on LO when getting in the car during summer provides instant cooling, especially useful during heatwaves. However, don't keep it on all the time, as it may overload the compressor, increase fuel consumption, and easily cause frost. Combining it with the auto button and adjusting the internal circulation air volume can double the cooling effect. When increasing the air volume, don't forget to close the windows and turn on internal circulation, otherwise, the air circulation inside the car will be poor. If the AC starts making a buzzing noise after long drives, it's best to check it early to prevent minor issues from becoming major problems.
