The Driver Information Center (DIC) comes on when the ignition is on.

If a problem is detected, a warning message appears on the display. Pressing and releasing the trip odometer reset stem on the DIC acknowledges some current warnings or service messages. Some messages only clear after the required action has been taken.

The DIC has different modes which can be accessed by pressing the trip odometer reset stem on the DIC. These modes are explained in the following section. The DIC trip odometer reset stem is located on the instrument panel cluster next to the DIC display. To scroll through the available functions, press and release the reset stem.
