What does 'rest' mean on Volkswagen air conditioning?

"The 'rest' on Volkswagen air conditioning refers to the residual heat heating function. Below are some related introductions about Volkswagen: 1. Introduction to Volkswagen: Volkswagen (German: Volkswagen) is an automobile manufacturing company headquartered in Wolfsburg, Germany, and is the core enterprise of the Volkswagen Group, one of the world's four major automobile manufacturers. 2. Volkswagen's brand culture: The history of the car's logo has undergone several changes, with the VW in the logo being the first letters of the full name. The logo appears to be composed of three 'V's made with the middle and index fingers, symbolizing the victory of Volkswagen and its products.
The REST button in Volkswagen cars is actually a very practical feature called residual heat utilization. When I drove my Volkswagen to go skiing last year, I often used it. After parking and turning off the engine, pressing the REST button automatically activates the air conditioning fan, which uses the residual heat from the recently run engine to continue blowing warm air. This way, in the sub-zero snowy conditions, when I got back from shopping, the car was still warm without needing to restart the engine and waste fuel. However, I should remind you that this feature is perfect for short-term use in winter—don’t exceed 15 minutes, as the fan still relies on the battery for power. Running it too long could drain the battery, which would be inconvenient, so I always make sure to turn it off after use. Overall, REST is like a thoughtful little assistant—energy-efficient and comfort-enhancing—especially convenient for those who frequently drive long distances.
I've played around with Volkswagen's REST function quite a bit, and it's pretty cool. In Chinese, it's called the residual heat heating system. Simply put, after you park and turn off the engine, pressing the REST button activates the fan, which draws in the residual heat from the engine to keep the warm air blowing for a while. I find the principle quite interesting—right after the engine stops, the heat is still there, and this system uses it to warm up the car, saving energy and reducing idle pollution. However, based on my experience as a mechanic, be careful not to force the REST function when there's no heat source, like when the engine is already cold—it won't do much then. Also, make sure to regularly check the battery and fan wiring to avoid sudden shutdowns from overuse. To me, it's a clever little design that reuses heat, making it both eco-friendly and practical.
