Press and release to turn off
Performance Traction Management
and return to the traction control and
StabiliTrak systems. The traction off
light and StabiliTrak OFF light
will go out.
Launch Control (Track
Mode Only)
A Launch Control feature is
available, within PTM (Z06 models,
Grand Sport models, and Stingray
with FE4), on all vehicles to allow
the driver to achieve high levels of
vehicle acceleration in a straight
line. Launch Control is a form of
traction control that manages tyre
spin while launching the vehicle.
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:
Any of the PTM modes are
selected. The TCS light comes
on the instrument panel and the
appropriate DIC message
displays.
The vehicle is not moving.
The steering wheel is pointing
straight.
Manual Transmissions
The clutch is pressed and the
vehicle is in 1 (First) gear.
The accelerator pedal is rapidly
applied to wide open throttle.
The Launch Control feature will
initially limit engine speed as the
driver rapidly applies the accelerator
pedal to wide open throttle. Allow
the engine rpm to stabilise.
A smooth, quick release of the
clutch, while maintaining the fully
pressed accelerator pedal, will
manage wheel slip. Complete shifts
as described in Manual
Transmission 0 185.
Automatic Transmissions
The brake pedal must be firmly
pressed to the floor, equivalent
to a panic brake event.
The accelerator pedal is rapidly
applied to wide open throttle. (If
the vehicle rolls due to wide
open throttle, release the
throttle, press the brake pedal
more firmly, and re-apply the
accelerator to wide open
throttle.)
The Launch Control feature will
initially limit engine speed as the
driver rapidly applies the accelerator
pedal to wide open throttle. Allow
the engine rpm to stabilise.
A smooth, quick release of the
brake pedal, while maintaining the
fully pressed accelerator pedal, will
manage wheel slip.
After the vehicle is launched, the
system continues in PTM.

systems designed for a closed
course race track and not intended
for use on public roads. The
