Boost Gage (ZR1 Only)

United States
For vehicles that have this gage, it is located near the
driver side of the instrument panel cluster.
This gage indicates vacuum during light to moderate
throttle and boost under heavier throttle.
It displays the air pressure level in the intake manifold
before it enters the engine's combustion chamber.
The gage is automatically centered at zero every time
the engine is started. Actual vacuum or boost is
displayed from this zero point. Changes in ambient
pressure, such as driving in mountains and changing
weather, will slightly change the zero reading.

Driver Information Center (DIC)

The Driver Information Center (DIC) display is located
on the instrument panel cluster and shows driver
personalization features and warning/status messages.
The DIC buttons are located on the instrument panel,
to the right of the cluster.
The DIC comes on when the ignition is turned on.
After displaying CORVETTE BY CHEVROLET, the DIC
shows the information that was last displayed before
the engine was turned off.
If a problem is detected, a warning message appears
on the DIC display. See DIC Warnings and Messages
Canada
on page 3-54 for more information.

DIC Operation and Displays

Depending on the features on the vehicle, the drive
gear may display on the DIC. See "Manual Paddle Shift"
under Automatic Transmission Operation on page 2-26
