Mode Only)
A Launch Control feature is

Performance Traction Management
(Z51 and Z06 with Magnetic Ride

driver to achieve high levels of
vehicle acceleration in a straight

This feature is intended for use
during closed course race events
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 (except Z51 and Z06

Management modes are
