.Dry conditions only.
.Requires more driving skill than in
other modes.
.StabiliTrak/ESC is off and engine
power is available for maximum
cornering speed.
In any PTM Mode, Launch Control is
available. Use PTM Race 2 for the
most consistent performance during
drag strip use. See “Custom Launch
Control ”in Track Events and
Competitive Driving (V-Series and
V-Series Blackwing) 0213.
Launch Control
If equipped, Launch Control is
available within Competitive Driving
Mode and PTM to allow high levels of
vehicle acceleration in a straight line.
Launch Control is a form of traction
control that manages tire spin while

266 DRIVING AND OPERATING
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:
.Competitive Driving Mode is
selected or any of the PTM modes
are selected. The traction off light
comes on in the instrument cluster
and the appropriate DIC message
displays.
.The vehicle is not moving.
.The steering wheel is pointing
straight.
Automatic Transmissions
.The brake pedal is 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
reapply the accelerator to wide open
throttle.Launch Control will initially limit
engine speed as you rapidly apply the
accelerator pedal to wide open
throttle. Allow the engine rpm to
stabilize. 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 Competitive
Driving Mode or PTM.
Competitive Driving Mode, PTM, and
Launch Control are systems designed
for a closed course race track and not
intended for public roads. The systems
are not intended to compensate for
lack of driver experience or familiarity
with the race track.
Limited-Slip Differential
If equipped, the Electronic
Limited-Slip Differential (eLSD) is
automatically activated. eLSD actively
monitors vehicle sensors and driver
inputs to determine the amount of
change for the conditions. With eLSD,
the vehicle has:
.Enhanced high-speed control.
.Improved traction through corners,
allowing more acceleration.
.More precise steering.
.Increased vehicle agility.
.Integration with StabiliTrak/
Electronic Stability Control (ESC).
For vehicles with eLSD, driven under
severe conditions, the rear axle fluid
should be changed. See Competitive
Driving Mode 0264 and
Maintenance Schedule 0408.
Cruise Control
{
Warning
Cruise control can be dangerous
where you cannot drive safely at a
steady speed. Do not use cruise
control on winding roads or in
heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could
lose control. Do not use cruise
control on slippery roads.
