Which is the recirculation mode, auto or man?
2 Answers
man is the recirculation mode. auto refers to automatic air conditioning. Here are the methods for selecting between recirculation and fresh air modes: 1. At startup: After turning on the car's air conditioning, first set the fan to the maximum speed and switch to fresh air mode. Open the car doors to expel hot air from the interior, then switch to recirculation mode. 2. While driving: Use recirculation mode in traffic jams to prevent the air conditioning from inhaling exhaust fumes from vehicles ahead; use fresh air mode during high-speed driving; use recirculation mode for urban driving. 3. When parked: In enclosed spaces with the engine idling, it's best to turn off the air conditioning.
I've been working with cars for decades, and the auto mode doesn't directly indicate recirculation. Recirculation refers to that independent button in the air conditioning system, often represented by an icon of an arrow circling inside the car, showing that air is circulating within the vehicle. In auto mode, the system automatically determines based on temperature sensors, such as prioritizing recirculation for quick cooling or heating when starting up. In manual mode, you need to press that button yourself to control recirculation, like turning it on in traffic to reduce inhaling exhaust fumes. Be careful not to keep recirculation on all the time, as it can lead to stale air or fogging inside the car. Check your car's AC panel; the recirculation button usually exists separately. Auto and manual are just overall operation modes—don't confuse them. Regularly cleaning the filter can also make circulation more effective.
