Thanks to the ID. Light, your ID.4 GTX can also communicate visually and, in conjunction with the navigation system, can help you get through traffic more calmly. The car greets you and translates the notices of your infotainment and assistance systems into light signals that lead you through traffic more calmly. As soon as you use the voice control, you receive a response to your voice via ID. Light. And when you leave the ID.4 GTX, the ID. Light will see you off with a farewell in the form of light signals.
