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 by your GM dealer 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. See Scheduled Maintenance on page 6-4. After an oil change, the oil life indicator must be reset. See Engine Oil Life System on page 5-17. See Engine Oil on page 5-14 and Oil Life Indicator on page 3-79 for more information. CHANGE TRANS FLUID - 47: This message will appear when it is time to change the transaxle fluid. See Scheduled Maintenance on page 6-4 for the proper fluid and change intervals. After the transaxle fluid has been changed, the transaxle fluid change indicator must be reset. See "How to Reset the Transaxle Fluid Indicator" under Automatic Transaxle Fluid on page 5-21. 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 your GM dealer as soon as possible. See Brake System Warning and Parking Brake Indicator Light on page 3-47. CHECK COOLANT LEVEL - 2: This message will appear when there is a low level of engine coolant. Have the cooling system serviced by your GM dealer as soon as possible. See Engine Coolant on page 5-24.
