Traffic light information enables the car to communicate with the infrastructure in select cities and metropolitan areas across the US. The car receives real-time signal information from the advanced traffic management system that monitors traffic lights. The link between vehicle and infrastructure is routed via the on-board LTE data connection and TTS servers.
While waiting at a connected traffic light, the driver information system in the instrument cluster, as well as the head-up-display (if equipped), indicates the time remaining until the signal changes to green.
