Launch Control (V-Series Only)
A Launch Control feature is available,
within Competitive Driving Mode
(V-Series) or Performance Traction
Management (V-Series), 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 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 (V-Series) or any of the
Performance Traction
Management modes are selected
(V-Series). 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 stabilize. 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 0 235.
