154 Driving and Operating
4. Apply the brakes 25 times from100 km/h (60 mph) to 50 km/h
(30 mph) while decelerating at
0.4 g. This is a medium brake
application. Drive for at least
1 km (0.6 mi) between
applications.
As with all high performance brake
systems, some amount of brake
squeal is normal.
Alternative Closed Course Brake
Burnishing Procedure
This brake burnish procedure
should only be run on vehicles with
the J55 Z51 factory equipped brake
system.
This procedure should only be run
on a track and only on dry
pavement. Brake pedal fade will
occur during this track burnish
procedure and can cause brake
pedal travel and force to increase.
This could extend stopping distance
until the brakes are fully burnished. 1. Start track lapping at lower speeds and lower braking
efforts for three minutes of driving. Allow for increased
braking distances due to
reduced brake output.
2. After Step 1, increase speed and braking effort for the next
six minutes of lapping,
gradually ending up at 90%
effort. Continue to allow for
increased braking distance due
to reduced brake output.
3. Cool the brakes by lapping with minimal light braking for six
minutes.
Brake Cooling Kit
Prior to any track event, high speed
driving event, or competitive driving,
the following should be completed:
. Ensure all brake cooling parts
are correctly and securely
installed.
. Install the rear lower control arm
cooling ducts per the instructions
included with the kit. After any
track event or competitive
driving, remove the rear lower
control arm cooling ducts. These
parts are for track use only. .
Inspect for and remove any
blockage in the ducts.
. Inspect and replace any duct
that has damage.

whenever you can.
Starting and
Operating
New Vehicle Break-In
Follow these recommended
guidelines during the first 2 414 km
(1,500 mi) of driving this vehicle.
Parts have a break-in period and
performance will be better in the
long run.
During the first 800 km (500 mi),
engine torque will be limited in low
gears.
For the first 322 km (200 mi):
. To break in new tires, drive at
moderate speeds and avoid hard
cornering.
. New brake linings also need a
break-in period. Avoid making
hard stops. This is
recommended every time brake
linings are replaced.
For the first 800 km (500 mi):
. Avoid full throttle starts and
abrupt stops.
. Do not exceed 4000 rpm.

{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

delete stored locations for the
automatic lift. If the vehicle is raised
automatically using GPS, it will
automatically lower once the vehicle
is located about 60 meters (197 feet)
from the programmed location.
Drivers can disable this function by
turning off GPS location through
their vehicle Front Lift System will
still operate, but only by using the
pushbutton command, and the “Auto
Lift Location Remembered”
confirmation message will not
display.
The Front Lift System can also be
used in accessory mode. Put the
vehicle in ACC/ACCESSORY mode,
then press and hold the button on
the center console for 10
consecutive seconds to
automatically raise the vehicle.
The DIC may display the message
“Lift System Unavailable” if the
following occur:
. Any doors are ajar.
. The hood is open. .
The vehicle is moving over
38 km/h (24 mph).
. Too many lift requests within a
short period.
The Front Lift System should not be
used to service the vehicle. Do not
place anything or body parts under
the vehicle while lifted. See
Recommended Fluids and
Lubricants 0295.
Competitive Driving Mode
If equipped, Competitive Driving
Mode, 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 the race track. Drivers who
prefer to allow the system to have
more control of the engine, brakes, and suspension are advised to turn
the normal traction control and
StabiliTrak/ESC systems on.
Competitive Driving Mode
Competitive Driving Mode allows full
engine power while StabiliTrak/ESC
helps maintain directional control of
the vehicle by selective brake
application. In this mode, the TCS is
off and Launch Control is available.
Adjust your driving style to account
for the available engine power. See
“Launch Control”
later in this
section.

however, despite the best intentions
of all concerned, misunderstandings
can occur. If your concern has not
been resolved to your satisfaction,
the following steps should be taken:
STEP ONE : Discuss your concern
with a member of dealership
management. Normally, concerns
can be quickly resolved at that level.
If the matter has already been

Vehicle Data
Recording and
Privacy
The vehicle has a number of
computers that record information
about the vehicle’s performance and
how it is driven or used. For
example, the vehicle uses computer
modules to monitor and control
engine and transmission
performance, to monitor the
conditions for airbag deployment
and deploy them in a crash, and,
if equipped, to provide antilock
braking to help the driver control the
vehicle. These modules may store
data to help the dealer technician
service the vehicle or to help GM
improve safety or features. Some
modules may also store data about
how the vehicle is operated, such as
rate of fuel consumption or average
speed. These modules may retain
personal preferences, such as radio
presets, seat positions, and
temperature settings.
