Here’s a tip for everyone (do it now, not when you need it!):
- Turn on your phone’s WiFi hotspot, get in the car and use the WiFi menu to connect the car to the phone.
- Turn off your phone’s WiFi hotspot.
Now your car “knows” your phone. If you ever find yourself in a situation where the car doesn’t connect to the internet and you can’t connect to it via the app to unlock/summon etc. As long as your phone has signal you can just turn on the hotspot. After a few minutes the car will find it and connect. This restores the car’s connectivity and you can try again. Remember: But don’t forget to switch it off or accidentally leave it on as the Model S (especially with nice satellite maps) uses a lot of data. Thanks to John Binks
