High Voltage Battery Information - Tesla CYBERTRUCK Owner's Manual

Cybertruck has one of the most sophisticated battery
systems in the world. The most important way to
preserve the high voltage Battery is to LEAVE YOUR
VEHICLE PLUGGED IN when you are not using it. This is
particularly important if you are not planning to drive
Cybertruck for several weeks.
NOTE: When left idle and unplugged, your vehicle
periodically uses energy from the Battery for system
tests and recharging the low voltage battery when
necessary.
There is no advantage to waiting until the Battery's level
is low before charging. In fact, the Battery performs best
when charged regularly.
NOTE: If you allow the Battery to discharge to 0%, other
components may become damaged or require
replacement (for example, the low voltage battery). In
these cases, you are responsible for repair and/or
transporting expenses. Discharge-related expenses are
not covered by the warranty or under the Roadside
Assistance policy.
The peak charging rate of the Battery may decrease
slightly after a large number of DC Fast Charging
sessions, such as those at Superchargers. To ensure
maximum driving range and Battery safety, the Battery
charge rate is decreased when the Battery is too cold,
the Battery's charge is nearly full, and when the Battery
conditions change with usage and age. These changes in
the condition of the Battery are driven by battery
physics and may increase the total Supercharging
duration by a few minutes over time. You can minimize
the amount of charge time by using Trip Planner (if
available in your market region) to warm the Battery
while driving to a Supercharger. See
page 158 for more information.
Battery Care
Never allow the Battery to fully discharge.
Even when Cybertruck is not being driven, its Battery
discharges very slowly to power the onboard
electronics. The Battery can discharge at a rate of
approximately 1% per day, though the discharge rate
may vary depending on environmental factors (such as
cold weather), vehicle configuration, and your selected
settings on the touchscreen. Situations can arise in
which you must leave Cybertruck unplugged for an
extended period of time (for example, at an airport
when traveling). In these situations, keep the 1% in mind
to ensure that you leave the Battery with a sufficient
charge level. For example, over a two week period (14
days), the Battery may discharge by approximately 14%.
Discharging the Battery to 0% may result in damage to
vehicle components. To protect against a complete
discharge, Cybertruck enters a low-power consumption
mode when the displayed charge level drops to
approximately 0%. In this mode, the Battery stops
supporting the onboard electronics and auxiliary low

voltage battery. Once this low-power consumption
mode is active, immediately plug in Cybertruck to
prevent a jump start and low voltage battery
replacement.
NOTE: If Cybertruck is unresponsive and does not
unlock, open, or charge, the low voltage battery may be
discharged. In this situation, try jump starting the low
voltage battery (see

Temperature Limits
For better long-term performance, avoid exposing
Cybertruck to ambient temperatures above 140° F (60°
C) or below -22° F (-30° C) for more than 24 hours at a
time.
Submerged Vehicle
As with any vehicle, if your Tesla has been exposed to
flooding, extreme weather events or has otherwise been
submerged in water (especially in salt water), treat it as
if it's been in an accident and contact your insurance
company for support. Do not attempt to operate the
vehicle before Tesla Service has inspected it, but you
should tow or move it away from any structures.
An unintentionally submerged vehicle is different than a
vehicle that intentionally enters water while off-roading.
In these situations, use Wade Mode. See

Battery Warnings and Cautions
Jump Starting on page
for more information.
WARNING: The high voltage system must be
serviced only by a trained technician. Under no
circumstances should you open or tamper with the
Battery. Do not disassemble, remove or replace
high voltage components, cables or connectors.
High voltage cables are typically colored orange
for easy identification.
CAUTION: If the Battery's charge level falls to 0%,
you must plug it in. If you leave it unplugged for an
extended period, it may not be possible to charge
or use Cybertruck without jump starting or
replacing the low voltage battery. Leaving
Cybertruck unplugged for an extended period can
also result in permanent Battery damage. If you
are unable to charge Cybertruck after attempting
to jump start the low voltage battery, schedule a
service appointment.
CAUTION: The Battery requires no owner
maintenance. Do not remove the coolant filler cap
and do not add fluid. If the touchscreen warns you
that the fluid level is low, use the mobile app to
schedule a service appointment.
