What does LO mean when displayed on the vehicle's air conditioning?
2 Answers
LO indicates the lowest temperature. When LO appears while adjusting the air conditioning temperature, it means the air conditioning has reached its lowest temperature. Some air conditioning systems may also display Hi or Me, which stand for high temperature and medium temperature, respectively. Here are some precautions regarding the use of car air conditioning: 1. Clean the air conditioning periodically. During use, the air conditioning often absorbs dust, forming dirt that can lead to mold growth over time. 2. Avoid setting the air conditioning temperature too low. Prolonged exposure to low temperatures can cause the body's endocrine system to struggle to adapt quickly, leading to various discomforts. Normally, the cabin temperature should be set to around 26~27 degrees Celsius. 3. Do not rest in the car with the air conditioning on while the engine is idling. When the car engine is running, incomplete combustion of gasoline in the cylinders can produce high concentrations of carbon monoxide, leading to poisoning or even death.
I remember when I drove an older car, the air conditioning also displayed LO, which stands for low, meaning the temperature had been adjusted to the system's lowest point, usually below the set range for automatic protection. At the time, I asked a mechanic friend, and he said it might be because the temperature setting was too low, triggering a safety mode, or it was too hot outside, and the air conditioning was working hard to cool. He suggested trying to manually adjust the temperature knob higher. If it still showed LO, then it would be necessary to check the sensors or circuits, otherwise it would affect driving comfort in the summer. Some people ignore this issue, resulting in soaring fuel consumption or frost forming at the vents, which is really annoying. Regularly checking the air conditioning settings during maintenance can prevent this. The key is not to let the fault worsen and affect the driving experience, as fluctuating temperatures inside the car are extremely uncomfortable.
