Jump Starting the Low Voltage (Lithium-Ion) Battery
Vehicles manufactured in Gigafactory Shanghai after approximately October 2021, and in the Fremont Factory after approximately December 2021, are equipped with a Lithium-Ion low voltage battery.
- Open the hood (see Opening Hood with No Power).
- Remove the maintenance panel by pulling it upwards to release the trim clips that hold it in place.
- If equipped with a HEPA filter, carefully fold the HEPA filter gasket towards the front of the vehicle to gain access to the low voltage jump post.
Pull back the black seal to reveal the positive jump post.
Remove the red cover and connect the external low voltage power supply’s red
positive (+) cable to the red positive (+) jump post. CAUTIONTo avoid damaging the vehicle, do not allow the positive cable to contact other metal components.
- The HEPA filter bolt (shown below) serves as the negative (-) jump post. Connect the low voltage power supply’s black negative (-) cable to the black negative HEPA jump post.
- Turn on the external power supply
(refer to the manufacturer’s instructions) for 20-30 seconds.CAUTIONIf you leave the power supply on for longer than 30 seconds, the low voltage battery may not self-recover and the vehicle might not be able to shift into Drive. Disconnect the power supply and the low voltage battery to enable another battery self-recovery attempt.NoteIf attempting to activate Transport Mode (to winch the vehicle onto a flatbed truck), the low voltage battery is not required to self-recover. Leave the power supply connected continuously until the vehicle has been secured.
- Open the driver door and wait two minutes.
- Ensure the vehicle is able to shift into Drive.
- Replace the maintenance panel by placing it back in its original location and pressing down until it is secure.
- Close the hood.
