Driver Information Center (DIC) Trip/Fuel Menu Items Press the trip/fuel button to display the Trip/Fuel Menu items. For more items see "DIC Operation and Displays" in the owner manual. DIC Warnings and Messages Warning messages are displayed on the DIC to notify the driver that the status of the vehicle has changed and that some action may be needed by the driver to correct the condition. If there is more than one message that needs to be displayed they will appear one after another. Some messages may not require immediate action, but you can press any of the DIC buttons on the instrument panel or the trip odometer reset stem to acknowledge that you received the messages and to clear them from the display. Some messages cannot be cleared from the DIC display because they are more urgent. These messages require action before they can be cleared. You should take any messages that appear on the display seriously and remember that clearing the messages will only make the messages disappear, not correct the problem. For information on other DIC messages, see "DIC Warnings and Messages" in the owner manual Index. BATTERY VOLTAGE This display shows the current battery voltage. If the voltage is in the normal range, the value will display. For example, the display may read BATTERY VOLTAGE 13.2 VOLTS. If the voltage is high or low, the display will read HIGH or LOW. Your vehicle's charging system regulates voltage based on the state of the battery. The battery voltage may fluctuate when viewing this information on the DIC. This is normal. See "Charging System Light" in the owner manual for more information. If there is a problem with the battery charging system, the DIC will display a message. See DIC Warnings and Messages on page 4‑12. INST ECON (Instantaneous Economy) This display normally shows instantaneous fuel economy. When the vehicle is in Auto Stop mode AUTO STOP or INST ECON = 99 MPG (l/00km) will be displayed. See Starting the Vehicle on page 3‑3 for more information. HOOD OPEN If the hood is not fully closed or there is a problem with the hood switch, this message will be displayed. Close the hood to clear the message. If the HOOD OPEN message continues to be displayed after verifying the 4-12
