Volt Gauge

The auxiliary gauge module displays the battery voltage. This gauge shows the condition of the charging system. The vehicle charging system regulates voltage based on the state of charge of the battery. It is normal for the volt gauge to fluctuate. Readings between the low and high warning zones indicate the normal operating range. Readings in the low warning zone can occur when a large number of electrical accessories are operating in the vehicle and the engine is left idling for an extended period. If there is a problem with the battery charging system, a message appears in the driver information center display and/or the charging system telltale comes on.
