Caution
Using a stealth engine sound setting
during spirited driving will cause the
exhaust system to overheat and damage
the variable exhaust valves. Do not use
this setting when auto-crossing or driving
on high speed tracks.
If available, engine sound settings change
when the variable exhaust valves open.
Steering (Assist Effort)
Adjusts from a lighter steering feel to
reduced assist for more steering feel.
Magnetic Ride Control
If equipped, this feature adjusts the shock
dampening firmness based on driving
conditions to improve comfort and
performance.
Drive Mode Customization
The vehicle is equipped to modify the
following vehicle settings base on vehicle
content. Through the infotainment home
screen, select Settings > Vehicle > “Drive

.Stealth, Tour, Sport, Track
Steering
This setting adjusts the effort required to
turn the steering wheel. The steering wheel
offers better feedback but requires more
effort as you move from Tour to Track.
.Tour, Sport, Track
Suspension
This setting adjusts the firmness of the
suspension in the vehicle. Suspension adjust
stiffness of the shocks and/or springs. The
ride is more comfortable at lower settings
and is stiffer at higher settings for better
control.

Performance Driving
If equipped, Competitive Driving mode,
Performance Traction Management (PTM),
and Launch Control are systems designed to
allow increased performance while
accelerating and/or cornering. This is
accomplished by regulating and optimizing
the engine, brakes, and suspension performance. These modes are for use at a
closed course race track and are not
intended for use on public roads. They will
not compensate for driver inexperience or
lack of familiarity with a race track.
Drivers who prefer to allow the system to
have more control of the engine, brakes,
and suspension are advised to turn on the
normal traction control and StabiliTrak/
Electronic Stability Control (ESC) systems on.
If equipped with E-Ray, there is a
Performance app on the infotainment screen
that shows the vehicle electric and engine
power/torque. See
“E-Ray Performance App”
later in this section for more information.
E-Ray Performance App
If equipped with E-Ray, to access the
Performance App, select the performance
app icon on the infotainment screen. The
landing screen of the Performance app is the
gauges page.
Gauges
The Gauges page shows the Electric
Power/Torque on the left gauge and the
engine power/torque on the right gauge.
Units of power or torque can be chosen at
the bottom of the page. The center of the
page is a wireframe view of the vehicle that
illuminates the front and/or rear axle as
each propulsion system is being used. The
brighter the wireframe display the more
power/torque is being provided.

The Dyno page shows both electric and
engine power/torque in numeric and script
format. This shows the usage over time in
intervals of 15 or 30 seconds, or one or
two minutes. This is the same data as
shown on the gauges page but in a different
viewing format.
While in P (Park) When the car is shifted into P (Park), the
viewing cursor appears to allow the driver
to analyze the data in the viewing time
increment.
The Gauges and Dyno pages include the
Hybrid battery gauge indicating how much
battery charge is present.
Electric power/torque can be either positive
or negative. When electric power is being
provided the gauge shows positive values
and lights up orange. When electric power is
being stored, the gauge shows negative
values and lights up green.
Engine power is only positive and lights up
white.

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.

210 Driving and Operating
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
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.
1. Using the DIC buttons on the right side
of the steering wheel, navigate to the
performance menu. See Instrument
Cluster 081.
2. Select Launch Control > Custom.
3. Scroll down to Launch RPM.
4. Adjust the desired RPM: 3500, 4000, 4500, 4750, 5000
5. Set Slip Target to custom desired setting.

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.

212 Driving and Operating
Cruise Control
Cruise control allows the vehicle to maintain
a constant speed without keeping your foot
on the accelerator pedal at speeds of about
40 km/h (25 mph) or above. 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.
Cruise control will disengage if:
.The Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control
(ESC) system activates to limit wheel spin.
See Traction Control/Electronic Stability
