BATTERY VOLTAGE LOW This symbol appears with the BATTERED VOLTAGE LOW message. CHANGE ENGINE OIL SOON When this message displays, it means that service is required for your vehicle. See your GM dealer. See Engine Oil on page 5-16 and Scheduled Maintenance on page 6-4 for more information. When you reset the CHANGE ENGINE OIL SOON message by clearing it from the display, you still must reset the engine oil life system separately. For more information on resetting the engine oil life system, see Engine Oil Life System on page 5-19. When this message displays, 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 (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. The normal battery voltage range is 11.5 to 15.5 volts. You can monitor battery voltage on the DIC by pressing the information button until you find BATTERY VOLTS. 3-76 CHECK BRAKE FLUID This message will display if the ignition is 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 Light on page 3-60 for more information. CHECK COOLANT LEVEL This message will display 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 5-23 for more information.
