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

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.

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.

280 Vehicle Care
Warning (Continued)
.Do not spin the tires in excess of
56 km/h (35 mph) on slippery
surfaces such as snow, mud, ice,
etc. Excessive spinning may cause
the tires to explode.
See Tire Pressure for High-Speed
Operation 0287 for inflation pressure
adjustment for high-speed driving.
All-Season Tires
This vehicle may come with all-season tires.
These tires are designed to provide good
overall performance on most road surfaces
and weather conditions. Original equipment
tires designed to GM's specific tire
performance criteria have a TPC specification
code molded onto the sidewall.
Consider installing winter tires on the
vehicle if frequent driving on snow or
ice-covered roads is expected. All-season tires
provide adequate performance for most
winter driving conditions, but they may not
offer the same level of traction or
performance as winter tires on snow or
ice-covered roads. See Winter Tires0280.
Winter Tires
This vehicle was not originally equipped
with winter tires. Winter tires are designed
for increased traction on snow and
ice-covered roads. Consider installing winter
tires on the vehicle if frequent driving on ice
or snow covered roads is expected. See your
dealer for details regarding winter tire
availability and proper tire selection. Also,
see Buying New Tires 0294.
With winter tires, there may be decreased
dry road traction, increased road noise, and
shorter tread life. After changing to winter
tires, be alert for changes in vehicle
handling and braking.
If using winter tires:
.Use tires of the same brand and tread
type on all four wheel positions.
.Use only radial ply tires of the same size,
load range, and speed rating as the
original equipment tires.
Winter tires with the same speed rating as
the original equipment tires may not be
available for H, V, W, Y, and ZR speed rated
tires. If winter tires with a lower speed
rating are chosen, never exceed the tire's
maximum speed capability.
Run-Flat Tires
This vehicle, when new, may have had
run-flat tires. There is no spare tire, no tire
changing equipment, and no place to store a
tire in the vehicle.
{Warning
While driving with run-flat tires at a
reduced inflation pressure, avoid making
sudden stops or severe maneuvers as the
handling capabilities of the tires will be
reduced. Driving too fast could cause loss
of control and you or others could be
injured. Do not drive over 80 km/h
(50 mph) with the tire operating at low
pressure. Drive cautiously and check the
tire pressure as soon as possible.
Run-flat tires can be driven up to 80 km
(50 mi) at speeds less than 80 km/h
(50 mph) after a loss of inflation pressure
has occurred. There is no need to stop on
the side of the road to change the tire. The
possible driving range after a pressure loss
will vary based on the vehicle load and
driving conditions. As soon as possible,
contact the nearest authorized GM or
run-flat servicing facility for inspection and
repair or replacement.

298 Vehicle Care
Caution
The wrong wheel can also cause
problems with bearing life, brake cooling,
speedometer or odometer calibration,
headlamp aim, bumper height, vehicle
ground clearance, and tire or tire chain
clearance to the body and chassis.
Tire Chains
{Warning
Do not use tire chains. There is not
enough clearance. Tire chains used on a
vehicle without the proper amount of
clearance can cause damage to the
brakes, suspension, or other vehicle parts.
The area damaged by the tire chains
could cause loss of control and a crash.
Use another type of traction device only
if its manufacturer recommends it for the
vehicle's tire size combination and road
conditions. Follow that manufacturer's
instructions. To avoid vehicle damage,
drive slowly and readjust or remove the
traction device if it contacts the vehicle.(Continued)
Warning (Continued)
Do not spin the wheels. If traction
devices are used, install them on the tires
of the drive axle only.
If a Tire Goes Flat
It is unusual for a tire to blow out while
driving, especially if the tires are maintained
properly. SeeTires0279. If air goes out of
a tire, it is much more likely to leak out
slowly. But if there ever is a blowout, here
are a few tips about what to expect and
what to do:
If a front tire fails, the flat tire creates a
drag that pulls the vehicle toward that side.
Take your foot off the accelerator pedal and
grip the steering wheel firmly. Steer to
maintain lane position, and then gently
brake to a stop, well off the road,
if possible.
A rear blowout, particularly on a curve, acts
much like a skid and may require the same
correction as used in a skid. Stop pressing
the accelerator pedal and steer to straighten
the vehicle. It may be very bumpy and
noisy. Gently brake to a stop, well off the
road, if possible. The vehicle has no spare tire, no tire
changing equipment, and no place to store
a tire.
If the vehicle has run-flat tires, there is no
need to stop on the side of the road to
change a flat tire. See
Run-Flat Tires0280.{Warning
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been driven
on while severely underinflated or flat
may cause a blowout and a serious crash.
Never attempt to re-inflate a tire that has
been driven on while severely
underinflated or flat. Have your dealer or
an authorized tire service center repair or
replace the flat tire as soon as possible.
{Warning
Special tools and procedures are required
to service a run-flat tire. If these special
tools and procedures are not used, injury
or vehicle damage may occur. Always be
sure the proper tools and procedures, as
described in the service manual, are used.
