What does 3zone mean in a car?

[KaiMarie]

3zone refers to the three-zone air conditioning system. When the switch light is on, it indicates that the rear air conditioning is controlled by the rear control panel. When the switch light is off, it means all air conditioning is uniformly controlled. Below is an introduction to the zoning feature: 1. Function: The zoning feature is not particularly high-tech; it simply adds air conditioning dampers to divide the air ducts more precisely. There is a main mixing damper, and the air is then distributed to each zone through separate ducts, with each zone having its own independent controller. 2. Purpose: It aims to provide a more comfortable environment for passengers, as some children or elderly individuals may not tolerate strong cold air or low temperatures well. The purpose of zoning is to accommodate the needs of passengers in each area, allowing everyone to freely adjust the air conditioning speed and temperature within their own space.
