Low Voltage System; 12V Battery - Tesla 2012 Model S Emergency Response Manual

12V BATTERY

In addition to the high voltage system, Model S has a low voltage system, powered by a traditional 12 volt battery. The low voltage system operates the
same electrical components found in conventional vehicles, including the supplementary restraint system (SRS), airbags, ignition, touchscreen, and
interior and exterior lights.
The low voltage system interacts with the high voltage system. The DC-DC converter supplies the 12V battery with power to support low voltage
functions, and the 12V battery supplies power to the high voltage contacts to allow power to flow out of the high voltage battery.
WARNING: Regardless of the disabling procedure you use, ALWAYS ASSUME THAT ALL HIGH VOLTAGE COMPONENTS ARE ENERGIZED! Cutting, crushing or touching high voltage
components can result in serious injury or death.
12V battery is located on the passenger side,
under the hood and the plastic access panel
