consistent performance
during drag strip use. See
“Custom Launch Control” in
Track Events and Competitive
Driving (V-Series and V-Series
Blackwing) 0246.
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 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.

302 Driving and Operating
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 0299 and
Maintenance Schedule 0471.
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.
With cruise control, a speed of
about 40 km/h (25 mph) or
more can be maintained
without keeping your foot on
the accelerator. Cruise control
does not work at speeds
below about 40 km/h (25 mph).
If equipped with a manual
transmission, the cruise
control will remain active when
