Why does the Mercedes-Benz air conditioner automatically blow air after turning off the engine?

[DiGiselle]

This is an intelligent design feature of Mercedes-Benz. When the vehicle detects that there are occupants inside while in a stationary state, it automatically activates the air conditioning ventilation to prevent unconscious suffocation of the occupants. Below are the relevant explanations: 1. Excessive Temperature: If the vehicle has been driven for an extended period and is parked with the engine turned off and power disconnected, the onboard computer will automatically activate the electric fan for cooling if it detects excessively high temperatures in the engine compartment. The electric fan in the engine compartment is not manually controlled but is managed by the onboard computer. 2. Function: The automatic air mode of the air conditioner refers to its intelligent air-blowing function. The automatic air feature adjusts the fan speed and mode based on the indoor temperature and environment, making it a highly intelligent functional mode.
