What does Passat rest mean?

[AngeloRose]

Passat rest refers to the preheating utilization mode setting, which utilizes the residual heat of the engine to continue providing warm air inside the vehicle for half an hour after the engine is turned off, after which it will automatically shut down. The purpose of preheating: Cold vehicles need to be preheated. Proper warm-up allows the engine oil to achieve better lubrication inside the engine, reducing wear; while driving, it is important to shift gears promptly, especially for manual transmission vehicles. During the break-in period, gears should be changed appropriately to avoid situations like high gear with low RPM or low gear with high RPM while driving. Principle of warm air formation: Warm air is generated from the heat produced during engine operation. When the engine's cooling system dissipates heat from the engine, a fan directs this dissipated heat into the vehicle's interior, creating warm air; when the warm air is not in use, the fan stops, and the warm air vent closes, causing all the dissipated heat to be released into the atmosphere.
