DIC Warnings and Messages 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. Multiple messages may appear one after another. Some messages may not require immediate action, but you can press the set/reset button to acknowledge that you received the message and clear it from the DIC display. Pressing any of the DIC buttons also acknowledges and clears any messages. 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. The following are the possible messages that can be displayed and some information about them. BATTERY SAVER ACTIVE This message displays when the system detects that the battery voltage is dropping beyond a reasonable level. The battery saver system starts reducing certain features of the vehicle that you may be able to notice. At the point that the features are disabled, this message is displayed. It means that the vehicle is trying to save the charge in the battery. Turn off all unnecessary accessories to allow the battery to recharge. The normal battery voltage range is 11.5 to 15.5 volts. CHANGE ENGINE OIL SOON This message displays when service is required for the vehicle. See your dealer/retailer. See Engine Oil on page 5-17 and Scheduled Maintenance on page 6-4 for more information. Acknowledging the CHANGE ENGINE OIL SOON message will not reset the OIL LIFE REMAINING. That must be done at the OIL LIFE screen under the vehicle information menu. See "Oil Life" under DIC Operation and Displays on page 3-52 and Engine Oil Life System on page 5-20. AUTOMATIC LIGHT CONTROL OFF This message displays when the automatic headlamps are turned off. See Exterior Lamps on page 3-15 for more information.
