Launch Control (Track
Mode Only)
A Launch Control feature is
available, within Competitive Driving
Mode (except Z51 and Z06 with
Magnetic Ride Control) or
Performance Traction Management
(Z51 and Z06 with Magnetic Ride Control), on all vehicles to allow the
driver to achieve high levels of
vehicle acceleration in a straight
line. Launch Control is a form of
traction control that manages tire
spin 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.
Launch Control is only available
when the following criteria are met:
.Competitive Driving Mode is
selected (except Z51 and Z06
with Magnetic Ride Control) or
any of the Performance Traction
Management modes are
selected (Z51 and Z06 with
Magnetic Ride Control). The
TCS light comes on the
instrument panel and the
appropriate DIC message
displays.
.The vehicle is not moving.
.The steering wheel is pointing
straight.Manual Transmissions
.The clutch is pressed and the
vehicle is in 1 (First) gear.
.The accelerator pedal is rapidly
applied to wide open throttle.
The Launch Control feature will
initially limit engine speed as the
driver rapidly applies the accelerator
pedal to wide open throttle. Allow
the engine rpm to stabilize.
A smooth, quick release of the
clutch, while maintaining the fully
pressed accelerator pedal, will
manage wheel slip. Complete shifts
as described in Manual
Transmission on page 9-31.
Automatic Transmissions
.The brake pedal must be firmly
pressed to the floor, equivalent
to a panic brake event.
.The accelerator pedal is rapidly
applied to wide open throttle. (If

more firmly, and re-apply the
accelerator to wide open
throttle.)
The Launch Control feature will
initially limit engine speed as the
driver rapidly applies the accelerator
pedal to wide open throttle. Allow
the engine rpm to stabilize.
A smooth, quick release of the
brake pedal, while maintaining the
fully pressed accelerator pedal, will
manage wheel slip.
After the vehicle is launched, the
system continues in Competitive
Driving Mode (except Z51 and Z06
with Magnetic Ride Control) or
Performance Traction Management
(Z51 and Z06 with Magnetic Ride
Control).
Competitive Driving Mode, PTM,
and Launch Control are systems
designed for a closed course race
track and not intended for use on
public roads. The systems are not
intended to compensate for lack of
driver experience or familiarity with
the race track.Limited-Slip Differential
(Except Z51 and Z06)
If equipped, the mechanical
limited-slip differential can give 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. For
vehicles with limited slip differential,
driven under severe conditions, the
rear axle fluid should be changed.
See Competitive Driving Mode on
page 9-43 andMaintenance
Schedule on page 11-2.
Limited-Slip Differential
(Z51 and Z06 Only)
If equipped, the Electronic Limited
Slip Differential (ELSD) is
automatically activated. ELSD
actively monitors vehicle sensors
and driver inputs to determine the
amount of change for the
conditions. With ELSD, the
vehicle has:
.Enhanced high-speed control.
.Improved traction through
corners, allowing more
acceleration.
.More precise steering.
.Increased vehicle agility.
.Integration with StabiliTrak.
For vehicles with limited slip
differential, driven under severe
conditions, the rear axle fluid should
be changed. See Competitive
Driving Mode on page 9-43 and
Maintenance Schedule on
page 11-2.

9-48 Driving and Operating
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 equipped with a manual
transmission, the cruise control will
remain active when the gears are shifted. The cruise is disengaged if
the clutch is pressed for several
seconds.
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 on page 9-37.
When road conditions allow for
using safely again, cruise control
can be turned back on.
If the brakes are applied, cruise
control disengages.

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 might have to step on the
accelerator pedal to maintain your
speed. When going downhill, you
might 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 vehiclespeed is maintained in the driver
selected gear and will not
automatically upshift or
downshift the transmission while
the driver
’s gear selection is
active.
.If driving in hilly terrain, cruise
control may not be able to
maintain vehicle speed if an
