184 Driving and Operating
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 below also
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.
Removing the ducts helps prevent debris
from being channeled into the rear brakes
during regular use of the vehicle.
.Inspect for and remove any blockage in
the ducts.
.Inspect and replace any duct that has
damage.

192 Driving and Operating
{Warning
Things you put inside your vehicle
can strike and injure people in a
sudden stop or turn, or in a crash.
.Put things in the rear area of your
vehicle. Try to spread the weight
evenly.
.Never stack heavier things, like
suitcases, inside the vehicle so
that some of them are above the
tops of the seats.
.Do not leave an unsecured child
restraint in your vehicle.
.When you carry something inside
the vehicle, secure it 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.
.Avoid driving at any one constant speed,
fast or slow, including the use of cruise
control.
.Avoid downshifting to brake or slow the
vehicle when the engine speed will
exceed 4000 rpm.
.Do not let the engine labor. Never lug the
engine. This rule applies at all times, not
just during the break-in period.
For the first 2 414 km (1,500 mi):
.Do not participate in track events, sport
driving schools, or similar activities.
.Check engine oil with every refueling and
add if necessary. Oil and fuel
consumption may be higher than normal.
Front Air Dam (and Splitter)
If equipped, the front air dam and splitter
have minimal ground clearance.
Under normal operation, the components
will occasionally contact some road surfaces
(speed bumps, driveway ramps, etc.). This
can be heard inside the vehicle as a scraping
noise. This is normal and does not indicate a
problem.
Use care when approaching bumps or
objects on road surfaces and avoid them
when possible.
If equipped, the Front Lift System may be
used to increase front air dam or splitter
clearance. See Front Lift System 0214.
Composite Materials
This vehicle may be equipped with parts
containing carbon fiber, sheet-molding
compound, or other composite materials.
Dealer-installed accessories may also contain
composite materials. These parts and
accessories may include the splitter or rocker
extensions.

198 Driving and Operating
Warning (Continued)
If unusual fumes are detected or if it is
suspected that exhaust is coming into the
vehicle:
.Drive it only with the windows
completely down.
.Have the vehicle repaired immediately.
Never park the vehicle with the engine
running in an enclosed area such as a
garage or a building that has no fresh air
ventilation.
{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. See
Shifting Into Park
0 196 and
Engine Exhaust 0197.
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 shift into N (Neutral). Once the
vehicle is stopped, P (Park) can be selected.

Driver Information Center (DIC) and ask the
driver if they would like to “Remember”the
location. The driver can select this function
through the steering wheel controls, see
Steering Wheel Controls 074. The driver can
also 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

See
Recommended Fluids and Lubricants
0 301.
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.

7. Verify coolant level after the engine isshut off and the coolant is cold.
If necessary, repeat coolant fill procedure
Steps 3−7.
If the coolant still is not at the proper
level when the system cools down again,
see your dealer.
Caution
If the pressure cap is not tightly installed,
coolant loss and engine damage may
occur. Be sure the cap is properly and
tightly secured.
Engine Overheating
The vehicle has several indicators to warn of
engine overheating.
There is an engine coolant temperature
gauge on the instrument cluster. See Engine
Coolant Temperature Gauge 084. The
vehicle may also display a message on the
Driver Information Center (DIC).
If the decision is made not to lift the hatch
but to get service help right away, see
Roadside Assistance Program 0311.
If the decision is made to lift the hatch,
make sure the vehicle is parked on a level
surface. Then check to see if the engine cooling fans
are running. There are two cooling fans
located in the front (one at each corner) and
two cooling fans in the rear (one on each
side of the engine). If the engine is
overheating, the fans should be running.
If they are not, do not continue to run the
engine, and have the vehicle serviced.
Caution
Do not run the engine if there is a leak
in the engine cooling system. This can
cause a loss of all coolant and can
damage the system and vehicle. Have
any leaks fixed right away.
If Steam Is Coming from the Engine
{Warning
Steam and scalding liquids from a hot
cooling system are under pressure.
Turning the pressure cap, even a little,
can cause them to come out at high
speed and you could be burned. Never
turn the cap when the cooling system,
including the pressure cap, is hot. Wait
for the cooling system and pressure cap
to cool.
If Steam Is Coming from the Engine
Compartment with no Overheat Warning
Water from rain and car washes could enter
the engine compartment and contact hot
surfaces. If steam is coming from the engine
compartment with no accompanying
overheat warning, no service is needed.
If No Steam Is Coming from the Engine
If an engine overheat warning is displayed
but no steam can be seen or heard, the
problem may not be too serious. Sometimes
the engine can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
If the overheat warning is displayed with no
sign of steam: 1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest fan
speed. Open the windows as necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or N (Neutral), and
let the engine idle.
