Jump Starting
7. When external low voltage power is no longer
required, disconnect both cables from the terminals
on the battery, beginning with the black negative (-)
cable.
The procedure for jump starting differs depending on
whether the low voltage battery is lead-acid or lithium-
ion. To determine which battery your vehicle uses, touch
Controls > Software > Additional Vehicle Information.
Both procedures are provided in this section.
8. Reinstall the cabin intake trim panel by placing it
back in its original location and pressing down until it
is secure.
The following instructions assume you are using an
external low voltage power supply (such as a portable
jump starter). If jump starting Model Y using another
vehicle, refer to the vehicle manufacturer's instructions.
9. Replace the maintenance panel by placing it back in
its original location and pressing down until it is
secure.
CAUTION: Model Y cannot be used to jump start
another vehicle. Doing so can result in damage.
10. Close the hood.
CAUTION: Avoid short circuits when jump starting
Model Y. Connecting cables to the wrong jump
post, touching leads together, etc., can damage
Model Y.
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.
Jump Starting the Low Voltage
(Lead-Acid) Battery
Vehicles manufactured in Gigafactory Shanghai before
approximately October 2021, and in the Fremont Factory
before approximately December 2021, are equipped with
a Lead-Acid low voltage battery.
1. Open the hood (see Opening Hood with No Power on
page 21).
2. Remove the maintenance panel by pulling it upwards
to release the trim clips that hold it in place.
If jump starting Model Y using another vehicle, refer to
that vehicle manufacturer's instructions. The following
instructions assume you are using an external low
voltage power supply (such as a portable jump starter).
3. 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.

3. 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 battery.
NOTE: Space to access the low voltage battery is
limited. Consider removing the push clips from the
rear cowl to improve accessibility.
4. Connect the low voltage power supply's red positive
(+) cable to the red positive (+) terminal on the low
voltage battery.
CAUTION: To avoid damaging Model Y, do not
allow the positive cable to contact other metal
components, such as the battery tie-down
bracket.
4. 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.
5. Connect the low voltage power supply's black
negative (-) cable to the black negative (-) terminal
on the low voltage battery.
CAUTION: To avoid damaging the vehicle, do
not allow the positive cable to contact other
metal components.
6. Turn on the external power supply (refer to the
manufacturer’s instructions). Touch the touchscreen
to wake it up.
NOTE: It may take several minutes to receive enough
power to wake up the touchscreen.
