Traction Control Switch Off, or Competitive Mode:
WARNING: This page is about a different car, the 2008 Saturn Sky and 2008 Pontiac Solstice. 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 VSES into a Competitive mode which will limit VSES control. When the Traction switch is pressed and held for 5 seconds the Traction and VSES will be disabled
