Connecting to Wi-Fi

Wi-Fi is available as a data connection method and is often faster than cellular data networks. Connecting to Wi-Fi is especially useful in areas with limited or no cellular connectivity. To ensure fast, reliable delivery of software and map updates, Tesla recommends leaving your vehicle connected to a Wi-Fi network whenever possible (for example, if parked in your garage overnight).

To connect to a Wi-Fi network:

  • Touch the cellular icon (usually LTE or 3G) on the top corner of your touchscreen. Model S will start scanning and display the detected Wi-Fi networks that are within range.
  • Select the Wi-Fi network you want to use, enter the password (if necessary), then touch 'Confirm.'
  • Your vehicle connects to the Wi-Fi network and will automatically connect to it whenever the network is within range.

You can also connect to a hidden network that isn't shown on the list of scanned networks. Just touch 'Wi-Fi Settings,' enter the name of the network in the resulting dialog box, select the security setting, then touch 'Add Network.'

Note: If more than one previously connected network is within range, Model S connects to the one most recently used.

Note: You can also use a mobile hotspot or your phone's Internet connection via Wi-Fi tethering (subject to fees and restrictions of your mobile carrier).

Note: At Tesla Service Centers, Model S automatically connects to the Tesla Service Wi-Fi network.

Drive to Calibrate Cameras

Model S must maneuver with a great deal of precision when Autopilot features are being used. Therefore, before some features (for example, Traffic-Aware Cruise Control or Autosteer) can be used for the first time or after certain Service repairs, the cameras must complete a self-calibration process. For your convenience, a progress indicator is displayed on the instrument panel.

Calibration typically completes after driving 20-25 miles (32-40 km), but the distance varies depending on road and environmental conditions. Driving on a straight road with highly-visible lane lines allows Model S to calibrate quicker. When calibration is complete, the Autopilot features are available for use. Contact Tesla only if your Model S has not completed the calibration process after driving 100 miles (160 km).

Note: If you attempt to use a feature that is not available until the calibration process is complete, the feature will not be enabled and the instrument panel displays a message.

Note: Model S must repeat the calibration process if the cameras are serviced by Tesla, and in some cases, after a software update.

Note:The self-calibration drive process is only applicable to Model S vehicles built after approximately October 12, 2016.
