The following are the possible messages that can be displayed and some information about them. A/C OFF FOR ENGINE PROTECTION This message displays when the engine coolant becomes hotter than the normal operating temperature. See Engine Coolant Temperature Gage on page 217. To avoid added strain on a hot engine, the air conditioning compressor is automatically turned off. When the coolant temperature returns to normal, the air conditioning compressor turns back on. You can continue to drive your vehicle. This message comes on while the ignition is in RUN. Press any of the DIC buttons to acknowledge this warning message and to clear it from the screen. This message continues to display for two seconds if it has not been acknowledged when the engine is turned off. It also re-displays for two seconds if the message has been acknowledged, but the condition still exists when the engine is turned off. If the condition still exists, the message re-appears when the engine is turned on. If this message continues to appear, have the system repaired by your dealer as soon as possible to avoid damage to the engine. 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. You can monitor the battery voltage by pressing the information button until BATTERY displays. 231
