Restarting the Touchscreen
If your touchscreen is unresponsive or demonstrates unusual behavior, you can restart it to potentially resolve the issue.
Warning: Only restart the touchscreen while the vehicle is stopped and in Park. The car status display, safety warnings, backup camera, etc. will not be visible during the restart.
- Shift into Park.
- Hold down both scroll buttons on the steering wheel until the touchscreen turns black and the Tesla logo appears.
- Wait approximately 30 seconds for the touchscreen to restart. If the touchscreen is still unresponsive or demonstrating unusual behavior after a few minutes, try powering the vehicle off (touch 'Controls' > 'Safety & Security' > 'Power Off').
Note: Restarting the touchscreen using the scroll buttons does not power Model 3 off and on.
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 3 can connect to it whenever the phone is within range.
To pair a phone, follow these steps while sitting inside Model 3:
- 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 3 to access your contacts and media files.
When paired, Model 3 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.
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 3 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 3 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 3 automatically connects to the Tesla Service Wi-Fi network.
To program HomeLink®(if equipped):
- Park Model 3 so that the front bumper is in front of the garage door, gate, or light you want to program.
Caution: Your device might open or close during programming. Before programming, make sure that the device is clear of any people or objects.
- Get the device's remote control and ensure it has a healthy battery. Tesla recommends replacing the battery in the device's remote control before Programming HomeLink.
- Touch the HomeLink icon on the top of the touchscreen.
- Touch 'Create HomeLink', then use the keyboard on your touchscreen to enter a name for your HomeLink device.
- Touch 'Enter' on the keyboard or touch 'Create HomeLink.'
- Touch 'Start' then follow the onscreen instructions.
Note: If you see a screen called “Train the receiver” while programming the device, remember that this is a time-sensitive step. After pressing the Learn/Program/Smart button on the device's remote, you only have approximately 30 seconds to return to your vehicle, press 'Continue', and then press the trained HomeLink device name twice. Consider having an assistant help with this step.
- Once your device is programmed, touch 'Save' to complete the HomeLink programming routine.
- Ensure HomeLink works as expected. In some cases the programming process may require multiple attempts before succeeding.
Once programmed, you can operate the device by touching its corresponding HomeLink icon on the touchscreen's status bar. HomeLink remembers the location of your programmed devices. When you approach a known location, the HomeLink control on the touchscreen automatically drops down. When you drive away, it disappears.
Note: For additional assistance or compatibility questions, contact HomeLink.
Adding and Removing Keys
Adding a new key card or key fob:
Note: If adding a key fob, ensure the key fob is at room temperature. Pairing may be unsuccessful if the key fob is cold.
- On the touchscreen, touch 'Controls' > 'Locks' then touch + in the Keys section.
- Scan your new key card or key fob on the key reader behind the cup holders on the top of the center console. After the new key card or key fob is recognized, remove it from the key reader.
- Scan an already-authenticated (i.e. already has access to the vehicle) key card or key fob on the key reader behind the cup holders on the top of the center console.
- When complete, the key list on the touchscreen displays the newly-authenticated key. You can customize its name by touching the associated pencil icon.
Adding a new phone key:
Note: To add a new phone key, Bluetooth must be enabled and the phone must have the Tesla mobile app installed and connected to the vehicle’s Tesla Account.
- While sitting in the vehicle, open the Tesla mobile app and select the appropriate vehicle (if there are multiple vehicles associated with the account), then touch 'Phone Key' > 'Start.'
- Scan an already-authenticated key card or key fob on the key reader behind the cup holders on the top of the center console.
- When the mobile app notifies you that the pairing was successful, touch 'Done.' The key list on the touchscreen ('Controls' > 'Locks') displays the new phone key. The name of the phone key is determined by the name used in the phone’s settings.
Removing a key:
When you no longer want a key to access your Model 3 (for example, you lost your phone or key card, etc.), you can remove the key.
- On the touchscreen, touch 'Controls' > 'Locks.'
- Find the key that you would like to delete in the key list, then touch the key’s associated trash icon.
- When prompted, scan an already-authenticated key card or key fob on the key reader behind the cup holders on the top of the center console to confirm the deletion. When complete, the key list no longer includes the deleted key.
Note: Model 3 requires at least one authenticated key card or key fob at all times. If only one key card is included on the key list, this key cannot be deleted.
Unlocking and Starting Your Vehicle Using the Tesla Mobile App
You can use the mobile app to unlock and start Model 3. This may be useful in cases where you do not have your key card or key fob, are experiencing issues with phone key, or are not physically close to the vehicle (for example, you want to unlock the vehicle for your spouse from across town).
Note: Your phone and vehicle must both be actively connected to cellular service and mobile access must be enabled on the touchscreen (Controls > Safety & Security > Allow Mobile Access) to allow the mobile app to communicate with your vehicle. Tesla recommends that you always have a functional physical key readily available if parking in an area with limited or absent cellular service, such as an indoor parking garage.
To unlock your vehicle using the mobile app:
- Open the mobile app.
- Touch 'Controls' > 'Unlock.'
- Touch 'Yes' on the confirmation popup window.
To start your vehicle using the mobile app:
- Open the mobile app.

- Reinstall the cover to the base of the phone dock by sliding it to the right.
- Lower the phone dock and reinstall the rubber mat.
Installing Front License Plate Bracket
To accommodate jurisdictions that require a license plate on the front of your vehicle, Model 3 is equipped with a license plate bracket. This bracket conforms to the shape of your vehicle's front bumper and is adhered to it using strong adhesive.
Note: Tesla recommends performing this procedure on a clean, dry vehicle during a warm day. Cold and/or wet conditions may result in reduced performance of the adhesive.
To install the front license plate bracket:
- Get isopropyl alcohol and test it on a non-visible painted surface of your vehicle to confirm that it does not damage or remove the paint.
- Clean the mounting site with isopropyl alcohol and allow to dry for at least one minute.
- Fully remove the protective tape from the adhesive at the top of the bracket and partially remove the tape from the top of the adhesive on each side. Leave the bottom half of the tape on the sides in place and fold the unattached tape outward for easy removal after aligning the bracket to the bumper.
- While tilting the top of the license plate bracket away from the bumper (to prevent adhering it to the wrong location), align the bottom center of the license plate bracket with the middle of the grille as shown.
Note: Be as precise as possible when aligning the bracket because you will be unable to reposition it once adhered to the bumper.
- While correctly aligned, move the top of the bracket against the bumper and apply pressure so that it is held in place by the adhesive.
- Remove the remaining tape from the sides of the bracket then press the entire bracket firmly against the bumper, ensuring the bracket is held in place by all adhesive areas.
- Once the bracket is securely mounted, use the four supplied screws to attach your license plate to the bracket (tighten to 3 Nm/2.2 ft-lbs).
Replacing Cabin Filters
Model 3 has air filters that prevent pollen, industrial fallout, road dust, and other particles from entering the cabin through the vents. Tesla recommends replacing these filters every 2 years (every year in China). Cabin filters are available for purchase at your nearest Service Center.
To replace the cabin filters:
- Turn off the climate control system.
- Move the front passenger seat fully rearwards and remove the front passenger floor mat.
- Working from top-to-bottom, use a trim tool to carefully release the right side panel from the center console.
- Use a clip pry tool to carefully release the push clips that secure the front passenger footwell cover to the instrument panel. Then, while supporting the footwell cover, disconnect the two electrical connectors and move the footwell cover aside.
- Remove the T20 screw that secures the cabin filter cover to the heating, ventilation, and air conditioning (HVAC) module then release the cabin filter cover and move it aside.
Note: If the HVAC module does not have a cabin filter cover, reinstall the trim panels and contact Tesla.
Warning: Do not stretch, bend or otherwise damage the orange High Voltage (HV) cables that are attached to the cabin filter cover. If the HV cables are damaged, immediately discontinue this procedure. HV shock can result in serious injury or death.
- Fold the upper cabin filter’s tab upward and the lower filter’s tab downward.
- Holding the tab on the upper cabin filter, pull the upper filter out from the HVAC module.
- Holding the tab on the lower cabin filter, pull the lower filter upwards and then out from the HVAC module.
- Ensuring that the arrows on both new filters face towards the rear of the vehicle, insert the lower cabin filter into the HVAC module and lower it into place. Then, insert the upper cabin filter above it.
- Fold the tabs inward so that the cabin filter cover can be installed.
- Install the cabin filter cover by engaging the lower cover tab then securing the T20 screw using. Tighten the screw to 1.2 Nm/0.89 ft-lbs.
- Reconnect the two electrical connectors to the components in the front passenger footwell cover, then resecure the cover with the push clips.
- Align the right side panel with the front and rear locator slots on the center console, then apply pressure until all of the clips are fully secure.
- Reinstall the front passenger floor mat then move the front passenger seat back into place.
Checking and Adjusting Tire Pressures

- Refer to the Tire and Loading Information label located on the driver’s center door pillar for the target tire pressure.
- Remove the valve cap.
- Firmly press an accurate tire pressure gauge onto the valve to measure pressure.
- If required, add or remove air to reach the recommended pressure.
Note: You can release air by pressing the metal stem in the center of the valve.
- Re-check pressure using the accurate tire gauge.
- Repeat steps 3 and 4 as necessary until the tire pressure is correct.
- Reinstall the valve cap to prevent dirt from entering. Periodically check the valve for damage and leaks.
Drive to Calibrate Cameras
Model 3 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 touchscreen.
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 3 to calibrate quicker. When calibration is complete, the Autopilot features are available for use. Contact Tesla only if your Model 3 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 touchscreen displays a message.
Note: Model 3 must repeat the calibration process if the cameras are serviced by Tesla, and in some cases, after a software update.
Replacing Hood Struts
Your hood struts can be replaced if they begin to fail for any reason. To replace your hood struts:

Disconnecting the Tow Hitch
After towing, remove the hitch:
- Insert the key and turn to align the top of the key with the Unlock icon.
- While firmly holding the bottom of the hitch (to prevent it from dropping to the ground), pull the locking cylinder out approximately 0.5 cm, and turn it clockwise until the Lock icon shifts to the top. At this point, the locking cylinder is unlocked in the "Open" position and the hitch drops out of the housing.
Warning: Be careful when turning the locking cylinder. If it does not lock into the "Open" position, it automatically retracts into its original "Closed" position and can pinch your fingers.
- Reinstall the dust cover on the hitch housing to prevent dirt from accumulating inside the housing by snapping in the push clips.
- Close the dust cover on the hitch's locking cylinder and store the hitch in a secure location.
Note: To maintain the hitch, regularly grease its surface with non-resinous grease.
In the unlikely event that a window behaves unexpectedly (touches the bright molding, fails to open or close properly, goes down more than normal when the door opens, etc.), you can calibrate it to potentially fix the issue.
To calibrate a window:
- Close the door with the affected window.
- Sit in the driver's seat and close the driver door.
- Use the driver window switch to raise the affected window until it stalls.
- Use the driver window switch to lower the affected window until it stalls.
- Use the driver window switch to raise the affected window until it stalls.
The window should now be calibrated. If the issue continues after attempting the calibration procedure a couple times, contact Tesla.
Opening Hood with No Power
