Page | 011 Battery Low-Voltage When the vehicle’s hood is opened, the 12V battery is accessible underneath the access panel next to the windshield. When necessary, the negative battery cable should be double cut to open the 12V battery circuit. Care should always be taken to not make contact with the positive and negative battery terminals when double cutting the negative battery cable. In addition to the high voltage system, Model X has a low voltage electrical system. Its 12V battery operates the SRS, airbags, windows, door locks, touchscreen, and interior and exterior lights. The DC-DC converter in the high voltage system charges the 12V battery, and the 12V battery supplies power to the high voltage contactors, allowing high voltage current to flow into and out of the high voltage battery. The 12V battery, outlined in red, is located under the hood and the plastic access panel. Model X Emergency Response Guide 9
