Tesla Cybertruck 2025-2026 Jump Starting Cybertruck

Jump Starting Cybertruck

To jump start Cybertruck, use an external power source capable of supplying at least 12V, such as a portable jump starter or another vehicle.

CAUTION: Use jump cables that are 30 ft. (9 meters) or less in length. Longer cables may damage Cybertruck or the external power source.

The steps below assume you are using an external low voltage power supply (such as a portable jump starter). If using another vehicle, follow the manufacturer’s instructions.

WARNING: Steering may be more difficult while Cybertruck is supported by an external power supply. Exercise extreme caution when repositioning the vehicle.

CAUTION: Cybertruck uses a 48V low voltage system. Some functions may be unavailable or degraded if using less than 30V. Avoid using low voltage components (climate control, USB-C ports, lights, etc.) during support. Cybertruck cannot jump start another vehicle, and avoid short circuits to prevent damage.

1. Open the powered frunk (see Opening the Powered Frunk with No Power).
2. Remove the maintenance panel by pulling it upwards to release the trim clips.
3. Connect the red positive (+) cable from the external power supply to the horizontal jump post next to the brake fluid reservoir. The post is marked with a + sign.

   CAUTION: Do not allow the positive cable to contact other metal components.

4. Connect the black negative (-) cable to the vertical jump post marked with a - sign. This post serves as the grounding location for external support.
5. If using a variable power supply, set the voltage between 12V–16.5V or 30V–50V.
6. Turn on the external power supply.

   CAUTION: Do not change the voltage while cables are connected.

7. Open the driver door and ensure the touchscreen is on and the low voltage system is responsive (may take up to 2 minutes).
8. Once external power is no longer required, shut off the external power supply.

   WARNING: Shut off the power before removing cables to avoid arcing.

9. Disconnect both cables, starting with the black negative (-) cable.

   NOTE: Cybertruck may not shift into Drive until the high voltage battery has charged and the low voltage system fully recovers (see Running Out of Range).

10. Replace the maintenance panel by pressing it back into its original location.

NOTE: If attempting to activate Tow Mode, leave the power supply connected continuously until the vehicle is secured (see Activate Tow Mode).
