Launch Control (Sport and Track
Mode Only)
A Launch Control feature is available, within
Competitive Driving Mode or PTM, on all
vehicles to allow the driver to achieve high
levels of vehicle acceleration in a straight
line. Launch Control is a form of TCS that
manages tire spin, and transmissions clutch,
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.
Caution
The new vehicle break-in period should be
completed before using the launch
control feature, otherwise performance
will be limited and damage may occur to
the powertrain/engine. See New Vehicle
Break-In 0 179.
Launch Control is only available when the
following criteria are met:
Competitive Driving Mode or any of the
PTM Modes are selected (if equipped). See
Driver Mode Control 0 198.
The steering wheel must be straight.
The driver door must be closed.
The vehicle must be in D (Drive) or
M (Manual Mode).
The parking brake must not be engaged.
Launching the Vehicle
Ensure the vehicle is in Competitive
Driving Mode or any of the PTM modes.
The brake pedal must be firmly pressed
to the floor, equivalent to a panic brake
event.
While maintaining the brake pedal, the
accelerator pedal is rapidly applied to
wide open throttle. If the vehicle rolls due
to wide open throttle or engine speed
does not exceed 3,000 Revolutions Per
Minute (RPM), release the throttle, press
the brake pedal more firmly, and reapply
the accelerator to wide open throttle.
If the engine is cold, the vehicle may
be limited to 3000 rpm until
conditions are suitable for
acceleration.
The Launch Control feature initially limits
engine speed as the driver rapidly applies
the accelerator pedal to wide open throttle.
Allow the engine RPMs to stabilize.
A smooth, quick release of the brake pedal,
while maintaining the fully pressed
accelerator pedal, will manage tire slip and
Driving and Operating
transmissions clutch. After the vehicle is
launched, the system continues in
Competitive Driving Mode or PTM.
Custom Launch Control
If equipped, Custom Launch Control allows
the following parameters for Launch Control
to be modified:
Launch RPM
Slip Target (5% 15%)
Adjusting the Launch RPM will also change
the behavior of the transmission during the
start of the launch. The higher the Launch
RPM, the faster the clutch will be applied
resulting in greater acceleration. This
parameter can be used to match the launch
behavior to the available tire traction. If the
driving wheels spin excessively during the
launch, reduce the Launch RPM.
To adjust the Launch RPM, all of these
conditions must be met:
Competitive Driving Mode or any of the
PTM Modes are selected (if equipped). See
Driver Mode Control 0 198.
The steering wheel must be straight.
The driver door must be closed.
