208 Driving and Operating
These lights are on when the vehicle is in
the Competitive Driving mode.
To select this optional handling mode, the
vehicle mode must be Sport or Track (if
equipped with PTM, then Competitive
Driving mode is only available in Sport).
Then quickly press
@on the center console
two times. ESC COMPETITIVE MODE displays
in the Driver Information Center (DIC).
When
@is pressed again, the traction off
light
iand StabiliTrak/ESC OFF light@
will go out.
Performance Traction
Management (PTM)
If equipped, PTM integrates the TCS,
StabiliTrak/ESC, and Magnetic Ride Control
systems to provide improved and consistent
performance when cornering. The amount of
available engine power is based on the
mode selected, track conditions, driver skill,
and the radius of each corner.
This light is on when the vehicle is in the
PTM mode.
To select PTM mode, the vehicle mode must
be in Track mode. Then quickly press
@on
the center console two times. Performance
Traction Wet —ESC On displays in the DIC.
PTM is activated in two different methods.
For more information on how to activate
PTM through Z Mode, see Driver Mode
Control 0196. To experience the performance benefit of
this system, after entering a curve and at
the point where normal acceleration occurs,
fully press the accelerator pedal. The PTM
system modifies the level of engine power
for a smooth and consistent corner exit.
The PTM system contains five modes. These
modes are selected by turning the MODE
switch on the center console. Scroll through
modes by turning the mode control dial.
The following is a DIC display description
and the recommended usage of each mode:

systems. The traction off light
iand

@will go out.
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 0177. 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
0196.
.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.

6. Return to the landing page of LaunchControl. Firmly press and hold the brake
pedal to activate Launch Control.
7. Fully press the accelerator. Release thebrake pedal to launch the vehicle.
Limited-Slip Differential
The standard mechanical 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
Performance Driving 0206 and
Maintenance Schedule 0316.
Stingray, E-Ray, and Z06 Models Only
The Electrical Limited-Slip Differential (eLSD)
located on the rear axle is a hydraulically
actuated clutch system. 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.

Return the tires to the recommended cold

driving has ended. See Vehicle Load Limits

Tire Pressure 0286.
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS)
uses radio and sensor technology to check
tire pressure levels. The TPMS sensors
monitor the air pressure in your tires and
transmit tire pressure readings to a receiver
located in the vehicle. Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure
recommended by the vehicle manufacturer
on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of a
different size than the size indicated on the
vehicle placard or tire inflation pressure
label, you should determine the proper tire
inflation pressure for those tires.)
