BATTERY VOLTAGE LOW - 6: This message will appear when the electrical system is charging less than 10 volts or if the battery has been drained. If this message appears immediately after starting, 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 (be sure to follow the manufacturer's instructions) to boost the battery after returning home or to a final destination. If this message appears while driving or after starting your vehicle and stays on, have it checked immediately to determine the cause of this problem. To help the generator recharge the battery quickly, you can reduce the load on the electrical system by turning off the accessories. You can monitor battery voltage on the DIC by pressing the INFO button. The normal range is 11.5 to 15.5 volts. CHANGE ENGINE OIL - 82: This means that the life of the engine oil has expired and it should be changed within 200 miles. See "Engine Oil" and "Filter Recommendations" in the Maintenance Schedule booklet. After an oil change, the Oil Life Indicator must be reset. See "Oil Life Indicator, How to Reset" in the Index. CHANGE TRANS FLUID - 47: This message will appear when it is time to replace the transaxle fluid. See the Maintenance Schedule booklet for the proper fluid and change intervals. CHECK BRAKE FLUID - 37: This message will display if the ignition is in ON to inform the driver that the brake fluid level is low. Have the brake system serviced by a technician as soon as possible. See "Brake System Warning Light" in the Index. CHECK COOLANT LEVEL - 2: This message will appear when there is a low level of engine coolant. Have the cooling system serviced by a technician as soon as possible. CHECK FUEL GAGE - 50: (Analog Cluster Only) This message will appear when the fuel supply is less than 5 gallons (18.9 L) and the display is turned off. A single chime will also sound when this message is displayed. CHECK GAS CAP - 61: This message will appear if the gas cap has not been fully tightened. You should recheck your gas cap to ensure that it's fully tightened. 2-100
