2009 Chevrolet Silverado 2500 HD Extended Cab Owner's Manual - Page 335

If cruise control is being used when StabiliTrak activates, the cruise control automatically disengages. The cruise control can be re-engaged when road conditions allow. See Cruise Control on page 3-13 for more information. If the system fails to turn on or activate, the StabiliTrak light along with one of the following messages will be displayed on the Driver Information Center (DIC): TRACTION CONTROL OFF, SERVICE TRACTION CONTROL, STABILITRAK OFF, SERVICE STABILITRAK. If these DIC messages appear, make sure the StabiliTrak system has not been turned off using the StabiliTrak on/off button. Then turn the steering wheel clockwise from the nine o'clock position to the three o'clock position. If this clears the message(s), the vehicle does not need servicing. If this does not clear the message(s), then turn the vehicle off, wait 15 seconds, and then turn it back on again to reset the system. If any of these messages still appear on the DIC, the vehicle should be taken in for service. For more information on the DIC messages, see Driver Information Center (DIC) on page 3-53. The StabiliTrak light will flash on the instrument panel cluster when the system is both on and activated. The system may be heard or felt while it is working; this is normal. The traction control disable button is located on the instrument panel below the climate controls. The traction control part of StabiliTrak can be turned off by pressing and releasing the StabiliTrak button if both systems (traction control and StabiliTrak) were previously on. To disable both TCS and StabiliTrak, press and hold the button for five seconds. 4-7
