Pairing a Bluetooth Phone

Pairing allows you to use your Bluetooth-capable phone hands-free to make and receive phone calls, access your contact list, recent calls, etc. It also allows you to play media files from your phone. Once a phone is paired, Model Y can connect to it whenever the phone is within range.

To pair a phone, follow these steps while sitting inside Model Y:

  • Ensure both the touchscreen and the phone are powered on.
  • On your phone, enable Bluetooth and ensure it is discoverable.
    Note: On some phones, this may require you to go to Bluetooth Settings for the remainder of the procedure.
  • Touch the Bluetooth icon on the top of the touchscreen.
  • On the touchscreen, touch 'Add New Device' > 'Start Search.' The touchscreen displays a list of all available Bluetooth devices within operating distance.
  • On the touchscreen, touch the phone with which you want to pair. Within a few seconds, the touchscreen displays a randomly generated number, and your phone should display the same number.
  • Check that the number displayed on your phone matches the number displayed on the touchscreen. Then, on your phone, confirm that you want to pair.
  • If prompted on your phone, specify whether you want to allow Model Y to access your contacts and media files.

When paired, Model Y automatically connects to the phone, and the touchscreen displays the Bluetooth symbol next to the phone’s name to indicate that the connection is active.

At any time, you can display the Bluetooth settings screen to change settings associated with a connected device. For example, you can designate a connected phone as the Priority Device. This is useful in situations where you have connected more than one phone, and both phones are frequently used in Model Y at the same time. Model Y automatically attempts to connect to the priority device before others.

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 'Controls' > Wi-Fi icon at the top of the Controls screen. Model Y begins to scan and display detected Wi-Fi networks that are within range.
    Note: If a known Wi-Fi network does not appear in the list, move Model Y closer to the access point or consider using a range extender.

    Note: When connecting to a 5G network (if available), check which channels are supported in your region.

    5G Network Channels Supported

  • Select the Wi-Fi network you want to use, enter the password (if necessary), then touch 'Confirm.'
  • Model Y connects to the Wi-Fi network. Whenever the network is within range, Model Y connects to it automatically.

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 Y connects to the one most recently used.

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

Hotspots and Connectivity:

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) to access the internet. To remain connected to Wi-Fi when shifting into Drive or Reverse, choose the connection from the Wi-Fi settings screen, then touch 'Remain connected in Drive.'

Burnishing the Brakes

You should burnish the brakes after replacing brake pads and/or brake rotors. In addition, burnishing the brakes might eliminate a situation where the brakes emit a high-pitched squealing noise while braking, especially if the noise is present while driving in the rain, driving in cold and/or humid climates, or if there is surface rust present on the brake components. Note that all vehicles with disk brakes can experience this situation and that braking performance is not affected.

To burnish the brakes:

Note: Be sure to comply with all local traffic safety laws and only perform maneuvers in a suitable location where such activity is legal, with little to no traffic.

  • Drive the vehicle at approximately 50 mph - 55 mph on a straight road.
  • Apply moderate, consistent pressure to the brake pedal to slowly decelerate the vehicle, releasing at 10 mph.
  • Repeat this procedure six times, waiting at least 30 seconds between applications.

Note: If the noise still persists, use your mobile app to contact Tesla or schedule a service appointment.

Drive to Calibrate Cameras

Model Y must maneuver with precision when Autopilot features are being used. Therefore, before some features can be used for the first time or after some types of service repairs, cameras must complete a self-calibration process. For your convenience, the touchscreen displays a progress indicator.

When calibration is complete, Autopilot features are available for use. Calibration typically completes after driving 20-25 miles, but the distance varies depending on road and environmental conditions. For example, calibration completes quicker when driving on a straight road with multiple lanes (such as a controlled-access highway), with highly-visible lane markings (in the driving lane as well as the adjacent lanes). Contact Tesla only if your Model Y has not completed the calibration process after driving 100 miles in the described conditions.

If a camera has shifted from its calibrated position (for example, the camera or windshield was replaced), you must clear the calibration. To do so, touch 'Controls' > 'Service' > 'Camera Calibration' > 'Clear Calibration.' When the calibration is cleared, Model Y repeats the calibration process. While this helps re-calibrate the cameras in many cases, 'Clear Calibration' may not resolve all camera and sensor concerns.

Note: To calibrate, cameras require highly-visible lane markings in both the driving lane and adjacent lanes (at least two lanes over on each side of the vehicle). For best results, drive in the middle lane of a multi-lane highway (ideally with at least five lanes) that has clear lane markings and minimal traffic.

Note: If you attempt to use a feature that is not available until the calibration process is complete, the feature is disabled and the touchscreen displays a message.

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