CHARGING SYSTEM FAILURE On some vehicles, if there is a problem with the generator and battery charging system, this message will appear on the DIC, a chime will sound, and the battery warning light on the instrument panel cluster will come on. Driving with this problem could drain your battery. Turn off all unnecessary accessories. Stop and turn off the vehicle as soon as it is safe to do so. Have the electrical system checked by your GM dealer immediately. See Battery Warning Light on page 3-40 and Voltmeter Gage on page 3-41 for more information. CHECK TIRE PRESSURE If your vehicle has the tire pressure monitor system and a low tire pressure is detected in any of the vehicle's tires, this message will appear on the DIC, along with a chime. Pressing any of the four DIC buttons will acknowledge the message and clear it from the DIC display. If your vehicle does not have the four DIC buttons, pressing the trip odometer reset stem will acknowledge the message and clear it from the DIC display. It will appear at each ignition cycle until the tires are inflated to the correct inflation pressure. CHECK OIL LEVEL If your vehicle has an oil level sensor and the oil level in the vehicle is low, this message will appear on the DIC. Check the oil level and correct it as necessary. You may need to let the vehicle cool or warm up and cycle the ignition to be sure this message will clear. Once the problem is corrected, pressing any of the four DIC buttons will acknowledge the message and clear it from the DIC display. If your vehicle does not have the four DIC buttons, pressing the trip odometer reset stem will acknowledge the message and clear it from the DIC display. This message will clear itself after 10 seconds, until the next ignition cycle. See Engine Oil on page 5-15 for additional information. CHECK WASHER FLUID If the washer fluid level is low, this message will appear on the DIC. Adding washer fluid to the windshield washer reservoir will clear the message. See Windshield Washer Fluid on page 5-37. Pressing any of the four DIC buttons will acknowledge the message and clear it from the DIC display. If your vehicle does not have the four DIC buttons, pressing the trip odometer reset stem will acknowledge the message and clear it from the DIC display. This message will clear itself after 10 seconds, until the next ignition cycle. 3-58
