where consistent zero to
60 and quarter mile times are
desirable.
Launch Control is only available
when the following criteria are met:
Competitive Driving Mode is
selected or any of the
Performance Traction
Management modes are
selected. The TCS light comes
on the instrument cluster and the
appropriate DIC message
displays.
The vehicle is not moving.
