Battery Information
Battery Warnings and Cautions
Warning: The Battery has no parts that an
owner or a non-Tesla authorized service
technician can service. Under no
circumstances should you open or tamper
with the Battery. Always contact Tesla to
arrange for Battery servicing.
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 Model S
without jump starting or replacing the 12V
battery. Leaving Model S unplugged for
an extended period can also result in
permanent Battery damage. If you are
unable to charge Model S, contact Tesla
immediately.
Caution: The Battery requires no owner
maintenance. Do not remove the coolant
filler cap and do not add fluid. If the
instrument panel warns you that the fluid
level is low, contact Tesla immediately.
Caution: Do not use the Battery as a
stationary power source. Doing so voids
the warranty.
