Battery Voltage
This display, available on some vehicles, shows the current battery voltage. If the voltage is in the normal range, the value will display.
For example, the display may read Battery Voltage 15.0 Volts. The vehicle's charging system regulates voltage based on the state of the battery. The battery voltage can fluctuate while viewing this information on the DIC. This is normal. See Charging System Light for more information.
If there is a problem with the battery charging system, the DIC will display a message.
