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. SeeNew Vehicle
Break-In 0189.
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 0208.
.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.
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
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 0208.
.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.

Limited-Slip Differential (Stingray
Models Without Z51 Performance
Package)
The electrical limited-slip differential
provides more traction on snow, mud, ice,
sand, or gravel. It works like a standard axle
most of the time, but when traction is low,
this feature allows the drive wheel with the
most traction to move the vehicle. See
Competitive Driving Mode 0215 and
Maintenance Schedule 0306.

Limited-Slip Differential (Stingray
With Z51 Performance Package
and Z06 model)
The Electrical Limited-Slip Differential (eLSD)
is a hydraulically actuated clutch system
inside the transaxle. It can infinitely vary
the clutch engagement between 0 and
2250 N*m (1659 lb-ft) of breakaway torque
between the rear wheels. When necessary it
responds from open to full engagement in
fractions of a second. Smaller clutch
adjustments happen even faster.
The eLSD:
.Uses the vehicle sensors and driver inputs
to determine the optimum amount of
clutch engagement for the conditions.
.Improves traction while cornering by
changing the engagement to achieve a
balance between directional control and
acceleration.
.Provides optimal engagement for
high-speed control and stability without
affecting precise steering and turn-in.
.Improves vehicle stability during spirited
driving and evasive maneuvers. It is fully
integrated with the Active Handling and
Performance Traction Management (PTM)
systems (if equipped).There are unique calibrations based on the
Traction Control System (TCS) setting. eLSD
modes change automatically when the
traction control button is pressed. No unique
input from the driver is required.
.Mode 1 is the standard mode when the
vehicle is started. It provides a touring
calibration with an emphasis on vehicle
stability. Mode 1 is also used in PTM
Wet mode.
.Mode 2 is engaged when both TCS and
StabiliTrak are turned off. This calibration
provides more nimble corner turn-in, and
is biased for better traction out of
corners.
.Mode 3 is engaged when PTM is engaged
in Dry, Sport 1 & 2, and Race modes. This
is a nimble calibration with similar
functionality as eLSD Mode 2, however, it
is integrated to work with PTM.
.Mode 4 is engaged when TCS is selected
off, but StabiliTrak remains on. Vehicle
stability is still the priority, while allowing
for optimized traction out of corners.
Cruise Control
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).
{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.
If the Traction Control System (TCS) begins
to limit wheel spin while you are using
cruise control, the cruise control
automatically disengages. See Traction
Control/Electronic Stability Control 0206.
When road conditions allow for using safely
again, cruise control can be turned back on.

Using Cruise Control on Hills
How well the cruise control works on hills
depends upon the vehicle speed, load, and
the steepness of the hills. When going up
steep hills, you may have to step on the
accelerator pedal to maintain your speed.
When going downhill, you may have to
brake or shift to a lower gear to keep your
speed down. If the brake pedal is applied,
cruise control will disengage.
Cruise Control in Manual Paddle Shift Gear
Selection
When the vehicle is in M (Manual Mode)
and the manual paddle shift controls are not
being used, cruise control operates in the
same manner as D (Drive). When the vehicle is in M (Manual Mode)
and the manual paddle shift controls are
being used, cruise control operates as
follows:
.If cruise control is active and a gear is
selected with the manual paddle shift
controls, the vehicle speed is maintained
in the driver selected gear and will not
automatically upshift or downshift the
transmission while the driver gear
selection is active.
.If driving in hilly terrain, cruise control
may not be able to maintain vehicle
speed if an upshift or downshift is not
selected by the driver. While driving on
hilly terrain and cruise control is active
with a manual paddle shift gear selection,
the driver must select the proper gear for
the terrain or select D (Drive) on the
shifter for full automatic transmission
operation.
Ending Cruise Control
.Step lightly on the brake pedal.
.Shift the transmission to N (Neutral).
.Press*.
.To turn off cruise control, press1. Erasing Speed Memory
The cruise control set speed is erased from
memory if
1is pressed or if the ignition is
