5-30 Instruments and Controls If a low tire pressure condition is detected by the system while driving, a message advising you to add air to a specific tire will appear in the display. See Tire Pressure on page 10‑49 and Tire Messages on page 5‑37 for more information. If the tire pressure display shows dashes instead of a value, there may be a problem with your vehicle. If this consistently occurs, see your dealer for service. Change Compass Zone Your vehicle may have this feature. To change the compass zone through the DIC, see Compass on page 5‑5. Calibrate Compass Your vehicle may have this feature. The compass can be manually calibrated. To calibrate the compass through the DIC, see Compass on page 5‑5. Blank Display This display shows no information. Vehicle 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 Voltage and Charging Messages 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.
