The coverage for the built-in Wi-Fi Hotspot depends on the wireless carrier network coverage. When you are in areas where coverage fluctuates, performance may be impacted. In a 2G-coverage area, the Wi-Fi Hotspot will not work. In a 3Gcoverage area, streaming data or video to your devices may result in the degradation of your service. View the coverage map.
Also, the vehicle ignition needs to be in the “Run” or “Accessory” position for the Wi-Fi Hotspot to be active.
