Battery Voltage
This display shows the current battery voltage. The vehicle's charging system regulates voltage based on the state of the battery.
The battery voltage may fluctuate when viewing this information on the DIC. This is normal.
If there is a problem with the battery charging system, the charging system light illuminates and/or the DIC displays a message.
See Charging System Light, Battery Voltage and Charging Messages and Battery Load Management for more information.
