sounds simple enough, but i tried it a bunch of times on mine and i get nothing in the middle of the display to say im in performance mode. I thought maybe Magnetic Ride Control is a have to but then I read this from GM and it seems not....
HIGH PERFORMANCE DRIVING FEATURES
The Traction Control system limits wheelspin and the Stability Control system assists
with directional control of the vehicle in difficult driving conditions. Both systems turn on automatically every time the vehicle is started. The
Traction Control/Stability Control button is located on the center console.
Press the button once to turn off Traction Control.
Press and hold the button to turn off both Traction Control and Stability Control. Press the button again to turn on Traction Control and Stability Control.
Driver Mode Control
The five driver modes provide enhanced performance for different driving conditions by changing the throttle progression, shift mode, steering, limited slip differential, ride control, traction control, exhaust sound, and other calibrations (if equipped).
Rotate the Driver Mode Control, located on the center console, to scroll through the modes of Weather, Eco, Tour, Sport, and Track.
Note: Allow a few seconds for the changes to be activated before the current mode is displayed in the DIC.
Competitive Driving Mode and Performance Traction Management
Competitive Driving Mode allows full engine power while Stability Control helps maintain directional control of the vehicle.
Performance Traction Management (available only with Magnetic Selective Ride Control) offers five modes of operation, all designed to provide consistent performance when cornering in a variety of track conditions.
When in the Track mode, press the Traction Control/Stability Control button twice to activate Competitive Driving Mode or Performance Traction Management.
so it seems we would still have Competitive Driving mode even without the Performance Traction Management that comes with having the mag. ride control. I did read in another forum that the wrong software on the vehicle could cause this problem, but no verification of that. I have not done the dec software update maybe I'll take it in for that and see what happens.
