Traction Control Switch Off, or Competitive Mode:
WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
The Traction switch has multiple functions depending on the switch sequence applied. The Traction will be re-enabled by default when an ignition cycle is performed. When the Traction switch is pushed once, only the Traction control will be disabled. When the Traction switch is pressed twice within a 5 second time frame the EBCM will disable Traction and put the vehicle stability enhancement system into a competitive mode which will limit the Vehicle Stability Enhancement System control. When the Traction switch is pressed and held for 5 seconds the Traction and Vehicle Stability Enhancement System will be disabled
