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.
