Radiator louvers on a 2025 Limited 4Runner

[MichaelG]

While installing an illuminated front logo I noticed there were 2 sets of plastic louvers in front of the radiator (4 on each side). Does anyone know if the louvers open and close and if so what controls the activation. During installation the louvers were in the open position. I can only imagine that they would close during extreme cold conditions.
Any advice would be appreciated.
