Tesla MODEL Y 2025+ - Jump Starting

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.
CAUTION:
Model Y cannot be used to jump start
another vehicle. Doing so can result in damage.
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
1.
Open the hood (see Opening the Hood with No Power on
page 212).
2.
Remove the maintenance panel by pulling it upwards to
release the trim clips that hold it in place.
3.
Carefully fold the HEPA filter gasket towards the front of
the vehicle to gain access to the low voltage jump post.
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.
CAUTION: To avoid damaging the vehicle, do not
allow the positive cable to contact other metal
components.
5.
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.
6. Turn on the external power supply (refer to the
manufacturer’s instructions) for 20 seconds only, then
switch off or disconnect the power supply.
CAUTION: If you leave the power supply on for
longer than 20 seconds, the low voltage battery
may not self-recover and the vehicle might not be
able to shift into Drive. If this occurs, after
disconnecting the power supply, disconnect the low
voltage battery, then reconnect the low voltage
battery to enable another battery self-recovery
attempt.
NOTE: If attempting to activate Tow 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.
7.
Open the driver door and wait two minutes.
8.
Ensure the vehicle is able to shift into Drive.
