Driver Information Center (DIC)
The Driver Information Center (DIC) displays information about the vehicle. It also displays warning messages if a system problem is detected. See Vehicle Messages for more information. All messages appear in the DIC display located in the center of the instrument panel cluster.
On some models, the DIC may show warning lights or indicators in the top portion of the display. See Warning Lights, Gauges, and Indicators for more information.
The vehicle may also have features that can be customized through the controls on the radio. See Vehicle Personalization for more information.
