Boost Gage Driver Information Center (DIC) The Driver Information Center (DIC) gives you the status of many of your vehicle's systems. The DIC is also used to display warning/status messages. All messages appear in the DIC display located at the bottom of the instrument panel cluster. The DIC buttons are located on the instrument panel, next to the steering wheel. The DIC comes on when the ignition is on. After a short delay, the DIC displays the information that was last displayed before the engine was turned off. United States Canada For the CTS-V, this gage is located in the instrument panel cluster. This gage indicates positive manifold pressure which is the induction air pressure level in the intake manifold before it enters the combustion chamber. This gage reads zero under light throttle before boost is generated. This gage automatically resets to zero every time the engine is started. The top line of the DIC display shows the DIC information. The bottom line of the DIC display shows the compass. The compass displays in the trip/fuel menus and in some vehicle information menus. If a problem is detected, a warning message appears on the display. Take any message that appears on the display seriously and remember that clearing the message only makes the message disappear, and does not correct the problem. 3-49
