Instruments and Controls 5-33 Vehicle Messages Messages displayed on the DIC indicate the status of the vehicle or some action that may be needed to correct a condition. Multiple messages may appear one after another. The messages that do not require immediate action can be acknowledged and cleared by pressing V (Set/Reset). The messages that require immediate action cannot be cleared until that action is performed. All messages should be taken seriously; clearing the message does not correct the problem. The following are the possible messages 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 below expected levels. The battery saver system starts reducing certain features of the vehicle that may be noticeable. 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 battery voltage on the DIC by pressing the vehicle information button until Battery Voltage is displayed. BATTERY VOLTS LOW This message displays when the electrical system is charging less than 10 volts or the battery has been drained. If this message appears immediately after starting the engine, it is possible that the generator can still recharge the battery. The battery should recharge while driving, but may take a few hours to do so. Consider using an auxiliary charger to boost the battery after returning home or arriving at a final destination. Make sure you follow the manufacturer's instructions. If this message appears while driving or after starting the vehicle and stays on, have it checked immediately to determine the cause of this problem.
