{Warning
To prevent exhaust gases from
entering the vehicle and heat from
damaging the vehicle, the engine
cover and all fluid fill plugs must
be secured before closing the
tonneau cover (convertible only)
and operating the vehicle. Make
sure all bolts are torqued to GM
specifications.
Running the Vehicle
While Parked
It is better not to park with the
engine running.
If the vehicle is left with the engine
running, follow the proper steps to
be sure the vehicle will not move.
SeeShifting Into Park 0168 and
Engine Exhaust 0170.
Dual Clutch
Transmission
This vehicle is equipped with a dual
clutch transmission that contains an
integrated rear differential. The dual
clutch transmission provides an
extremely connected feel due to the
direct connection between the
engine and gear box. This
arrangement provides very fast shift
times for maximum performance.
Automatic driving mode is selected
by pulling D on the transmission
range selection panel and provides
fully automatic shifting operation which can be further refined using
driver mode control. Upshifts may
be delayed regardless of mode
selection or ambient temperature
until the engine is warmed up.
Manual operation can also be
selected. See Manual Mode later in
this section.
This transmission is electronically
controlled. The shift switches are on
the center console. The selected
gear position will illuminate red on
the shift switch, while all others will
display in white. The indicator on
the shift switch may flash if the shift
is not immediate or if the gear is not
fully engaged. This may occur in
very cold conditions or when Double
Paddle Declutch is used.
The transmission does not operate
when the vehicle is off.
If the vehicle is in ACC/
ACCESSORY, the transmission can
be shifted into P (Park).
If ENGINE START/STOP is pressed
twice while at a relatively high
speed, the engine will turn off and
the transmission will automatically

Double Paddle Declutch allows the
vehicle to temporarily disconnect
the engine from the wheels
–similar
to N (Neutral). This feature is
activated by pulling and holding
both the + paddle and −paddle at
the same time while the vehicle is in
R (Reverse), D (Drive), or M
(Manual Mode). The vehicle will
remain in this condition until both
the + paddle and −paddle are
released.
The R, D, or M indicator on the
center shift console will flash red to
indicate that the vehicle is in Double
Paddle Declutch. In addition, the
current gear state indicator in the
DIC may dim to gray to indicate that
the vehicle is in Double Paddle
Declutch.
To exit Double Paddle Declutch,
release both the + paddle and −
paddle. The engine will reconnect to
the wheels and the shift indicator
will stop flashing. There are two
Double Paddle Declutch exit styles:

clutch. After the vehicle is launched,
the system continues in Competitive
Driving Mode or PTM.
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.
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 0163.
Limited-Slip Differential
(without Z51)
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. See
Competitive Driving
Mode 0192 and
Maintenance Schedule 0286.
Limited-Slip Differential
(with Z51)
The Electronic 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.
