What are the button functions of the Toyota Vellfire?

[SanKimberly]

Toyota Vellfire's button functions are as follows: Hazard Warning Light: Used to alert surrounding vehicles to prevent rear-end collisions. Internal/External Air Circulation: Internal circulation provides air from inside the vehicle, while external circulation brings in outside air to replace the existing interior air. During traffic jams, in tunnels, or when external air quality is substandard, prioritize using internal circulation. On highways, switch to external circulation approximately every hour to refresh the air inside and outside the vehicle to prevent oxygen deprivation. Temperature Zone Sync: This function allows changing only the driver's seat temperature, and the other zones will follow the same adjustment. When this sync is turned off, each zone can be set individually to meet the needs of passengers in different positions.
