How to Jump Start a Tesla Model Y

1. Open the hood using the no-power procedure and remove the maintenance panel by pulling it upwards to release its trim clips.
2. Fold the HEPA filter gasket toward the front of the vehicle to reach the low voltage jump post.
3. Pull back the black seal, remove the red cover, and attach the power supply's red positive (+) cable to the red positive (+) jump post.
4. Look under the black plastic trim piece to find the HEPA filter bolt, which is the negative (-) jump post, and attach the black negative (-) cable to it.
5. Turn on the external power supply and touch the touchscreen to wake the vehicle.
6. When finished, disconnect both cables, starting with the black negative (-) cable, then reinstall the maintenance panel and close the hood.

• Model Y cannot be used to jump start another vehicle; doing so can cause damage.
• Avoid short circuits and do not let the positive cable touch other metal components.
• The touchscreen may take several minutes to wake up.
