Opening the Powered Frunk with No Power

In the unlikely event that Cybertruck has no low voltage power, you will be unable to open the powered frunk using the touchscreen, mobile app, or powered frunk button.

It is necessary to open the powered frunk before attempting to jump start Cybertruck.

To open the powered frunk when Cybertruck has no power, you need a power source that provides between 9V and 16.5V (such as a 12V portable jump starter or another vehicle), or a power source that provides between 30V and 50V. A standard 9V battery may not have enough power to open the powered frunk if Cybertruck has no power. Instead, use a portable jump starter or another vehicle.

The steps below assume you are using an external low voltage power supply (such as a portable jump starter).

Note
The following steps do not open the powered frunk if Cybertruck is locked and has low voltage power.
  1. Locate the front trunk access terminal beneath the front-left wheel well, behind the headlights.

  2. Use your finger or a trim tool to loosen the cover, then pull it down and toward you to remove it and expose the terminals. The cover is attached to a loop of cable containing both the red positive (+) and the black negative (-) terminals.

  3. Carefully pull the terminals out from the cavity.

  4. If you are using a variable power supply, set the supplied voltage to a value between 9V and 16.5V or between 30V and 50V.

    CAUTION
    If you are using a variable power supply, do not change the supplied voltage while the cables are connected.
  5. Connect the low voltage power supply's red positive (+) cable to the red positive (+) terminal.
  6. Connect the low voltage power supply's black negative (-) cable to the black negative (-) terminal.

    Note
    Applying external low voltage power to these terminals only releases the hood latches. You cannot charge the low voltage battery using these terminals. Do not leave the low voltage power cables connected to the terminals for more than 30 seconds – remove from the vehicle's terminals as soon as the hood latches.
  7. Turn on the external power supply (refer to the manufacturer’s instructions). The latches are immediately released and you can now open the powered frunk to access the front trunk area.
  8. Shut off the external power supply.

    Warning
    Shut off the external power supply before removing either cable. Removing the cables while the external power source is active may cause arcing.
  9. Disconnect both cables, beginning with the black negative (-) cable.
  10. Feed the terminals back into the cavity and then press the cover gently but firmly back into place to ensure that it is secured.
