DIC Operation and Displays
The DIC has different displays which can be accessed by using the DIC buttons on the turn signal lever, located on the left side of the steering wheel. The DIC displays trip, fuel, and vehicle system information, and warning messages if a system problem is detected.
The bottom of the DIC display shows the position of the shift lever and the odometer. It may also show the direction the vehicle is driving.
In cold weather the DIC display may change slowly. This is normal and will move more quickly as the vehicle's interior temperature rises.
