GAGE INFO (Information): Use this button to display oil pressure, oil life, coolant temperature, tire pressure and battery information. Press the GAGE INFO button until OIL PRESSURE appears in the display. If there are no problems detected with the oil pressure, the display will show OIL PRESSURE NORMAL. If a low oil pressure condition is detected, the display will show OIL PRESSURE LOW. If you see the OIL PRESSURE LOW message, your vehicle could be low on oil or the oil is not going through the engine properly. See your GM dealer for service. Press the GAGE INFO button until COOLANT TEMP appears in the display. If there are no problems detected with the temperature, COOLANT TEMP NORMAL will appear in the display. If the temperature is too high, COOLANT TEMP HOT will appear in the display. If you see the COOLANT TEMP HOT message, the engine is overheated. You should pull off the road, stop your vehicle and turn off your engine as soon as possible. This manual explains what to do. See Engine Overheating on page 5-26. Press the GAGE INFO button until the display shows BATTERY STATE. If the voltage is normal the display will show BATTERY STATE NORMAL. If the voltage drops below 10.5 volts, the display will show BATTERY STATE LOW. If the voltage is above 16.2 volts, the display will show BATTERY STATE HIGH. If the display shows the high or low message, you need to have your battery and charging system checked. See your GM dealer. Press the GAGE INFO button until OIL LIFE INDEX appears in the display. The OIL LIFE INDEX NORMAL display will show an estimate of the oil's remaining useful life. When the oil life index is less than 10 percent, the display will show OIL LIFE INDEX CHANGE OIL. This means service is required for your vehicle. See your GM dealer. In addition to the engine oil life system monitoring the oil life, additional maintenance is recommended in the Maintenance Schedule in this manual. See Part A: Scheduled Maintenance Services on page 6-4 and Engine Oil on page 5-13 for more information. When you have the oil changed according to the maintenance schedule, you will have to reset the engine oil life system. To reset the engine oil life system, see "How to Reset the Engine Oil Life System" under Engine Oil Life System on page 5-17. Press the GAGE INFO button until TIRE PRESSURE appears in the display. TIRE PRESSURE NORMAL is displayed when the check tire pressure system believes your vehicle's tire pressures are normal. If a potential tire pressure problem is detected, the display will show CHECK TIRE PRESSURE. 3-49
