Jump Starting - Tesla CYBERTRUCK Owner's Manual

To jump start Cybertruck, use an external power source
that is capable of supplying at least 12V, such as a
portable jump starter or another vehicle.
CAUTION: When jump starting Cybertruck, use
jump cables that are 30 ft. (9 meters) or less in
length. Using cables that are longer than 30 ft. (9
meters) may result in damage to Cybertruck or to
the external power source.
The steps below assume you are using an external low
voltage power supply (such as a portable jump starter).
If you are using another vehicle to jump start
Cybertruck, follow the manufacturer's instructions.
WARNING: It may be more difficult to steer
Cybertruck when the vehicle is being supported by
an external low voltage power supply. The wheels
may not be as responsive to the steering wheel as
expected, and extreme caution should be taken
when repositioning Cybertruck.
CAUTION: Cybertruck uses a 48V low voltage
architecture. As a result, some functions may be
unavailable or degraded if you are supporting
Cybertruck with less than 30V (for example,
another vehicle or a 12V portable jump starter).
CAUTION: Avoid using low voltage components of
Cybertruck (such as the climate control system,
cabin USB-C ports, lights, etc.) when the vehicle is
being supported by an external low voltage power
supply. Doing so may disable low voltage systems
and make it necessary to jump start Cybertruck
again.
CAUTION: Cybertruck cannot be used to jump
start another vehicle. Doing so can result in
damage.
CAUTION: Avoid short circuits when jump starting
Cybertruck. Connecting cables to the wrong jump
post, touching leads together, etc., can damage
Cybertruck.
1. Open the powered frunk (see
Frunk with No Power on page
2. Remove the maintenance panel by pulling it upwards
to release the trim clips that hold it in place.

Jump Starting

3. Connect the external low voltage power supply's red
positive (+) cable to the horizontal jump post
mounted next to the brake fluid reservoir. The
positive jump post is marked with a + sign.
CAUTION: To avoid damaging Cybertruck, do
not allow the positive cable to contact other
metal components.
4. Connect the external low voltage power supply's
black negative (-) cable to the vertical jump post. The
negative jump post is marked with a - sign. This jump
post is used as a grounding location for the external
support.
5. If you are using a variable power supply, set the
supplied voltage to a value between 12V and 16.5V or
between 30V and 50V.
6. Turn on the external power supply.
CAUTION: If you are using a variable power
supply, do not change the supplied voltage
while the cables are connected. Doing so may
cause damage to the vehicle.
7. Open the driver door and ensure that the
touchscreen is on and the low voltage system is
responsive. This may take up to two minutes.
