SERVICE CHARGING SYSTEM On some vehicles, if there is a problem with the battery charging system, this message will appear on the DIC. Under certain conditions, the battery warning light may also turn on in the instrument panel cluster. See Battery Warning Light on page 3-40. The battery will not be charging at an optimal rate and the vehicle will lose the ability to enter the fuel economy mode. The vehicle is safe to drive, however you should have the electrical system checked by your GM dealer. 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. SERVICE STABILITY If you ever see the SERVICE STABILITY message, it means there may be a problem with your StabiliTrak® system. If you see this message, try to reset the system. Stop; turn off the engine; then start the engine again. If the SERVICE STABILITY message still comes on, it means there is a problem. You should see your GM dealer for service. The vehicle is safe to drive, however, you do not have the benefit of StabiliTrak®, so reduce your speed and drive accordingly. 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. SERVICE RIDE CONTROL If a problem occurs with the suspension system, this message will appear on the DIC. See your GM dealer. 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. 3-63
