power input. Certain climate control
settings can lead to higher fuel usage.
The following climate control settings
use more fuel:
.MAX air conditioning mode
.Defrost mode
.Extreme temperature settings, such
as 15° C (60° F) or 32° C (90° F)
.High fan speed settings
To help reduce fuel usage:
.Use the full automatic control as
described under “Automatic
Operation.”
.Select a temperature setting that is
higher in hot weather and lower in
cold weather.
.Turn off the air conditioning when
it is not needed.
.Only use defrost to clear the

The solar sensor, located in the
defrost grille in the middle of the
instrument panel, monitors the solar
heat. Do not cover the solar sensor or
the system will not work properly.
There is also an exterior temperature
sensor behind the front grille. This
sensor reads the outside air
temperature and helps maintain the
temperature inside the vehicle. Any
cover on the front of the vehicle,
could cause a false reading in the
displayed temperature. The climate control system uses the
information from these sensors to
maintain comfort settings by
adjusting the outlet temperature, fan
speed, and air delivery mode. The
system may also supply cooler air to
the side of the vehicle facing the sun.
The recirculation mode will also be
used as needed to maintain cool
outlet temperatures.
Afterblow Feature
If equipped, under certain conditions,
the fan may stay on or may turn on
and off several times after you turn
off and lock the vehicle. This is
normal.

216 DRIVING AND OPERATING
Brake Cooling (V-Series Blackwing)
Prior to any track event, high speed
driving event, or competitive driving,
complete the following:1. Ensure all the brake cooling parts are correctly secured and installed.
2. Inspect and replace any deflectors that have damage.
3. Inspect for blockage in the front brake cooling duct prior to every
event.
If improved brake cooling is desired,
install the ball joint protector front
shields, remove both upper and lower
rear rotor shields, and install the rear
lower control arm cooling deflectors,
per the instructions included with the
brake cooling kit. These parts are for
track use only. After track events
reinstall original front and rear rotor
shields, and remove rear lower control
arm cooling deflectors.

1. Front Lower Control Arm Deflector
2. Front Brake Cooling Duct Brake Pad Wear Sensors
If equipped, the brake pad wear
sensors need to be removed from the
brake calipers prior to any track or
racing event. The original sensors can
be reinstalled if significant brake pad
wear is not observed. Refer to
Brake
Pad Life System (If Equipped) 0346.
If the sensors are not reinstalled after
the track event, install brake pad wear
sensor plugs. See your dealer.
The V-Series Blackwing is equipped
with brake pad wear sensors which are
track capable and should not be
disabled for track and racing.
A message will display in the Driver
Information Center (DIC) when the
brake pads show excessive wear.
Brake Fluid
Replace existing brake fluid with a
qualified DOT 4 high performance
brake fluid from a sealed container.
Brake fluid with a dry boiling point
>310 °C (590 °F) is qualified. If high
performance brake fluid is used,
replace it with GM approved brake
fluid before driving on public roads.
If high performance brake fluid is in
the vehicle and the age of the brake

fluid is over a month old or unknown,
replace the brake fluid before track
events and competitive driving. Do
not use silicone or DOT 5 brake fluids.
Disconnect the battery before bleeding
the system, replacing the pads, or any
other work. The battery must be
disconnected to prevent the brake
master cylinder from pressurizing the
hydraulic system during its automated
self diagnostic tests that may occur
when a door is opened or the remote
key is present.
Check the fluid level before each
competitive driving event.
Brake System Flushing & Bleeding
The J55 brake system requires specific
processes for bleeding and fluid
flushing. These can be found in the
service manual.
Properly bleeding the brake system is
required for proper operation of the
hydraulic brake system.
Brake Leak Detection
The hydraulic braking system has
advanced diagnostic capability to help
detect hydraulic leaks, trapped air,and other performance issues. These
diagnostics are active when the
hydraulic system is powered. In order
to avoid inadvertently setting a leak
Diagnostic Trouble Code (DTC),
disconnect the battery before
servicing the brake system.
If the vehicle sets a DTC related to a
brake system leak, the Brake System
Warning Light will come on and
vehicle speed may be limited to
100 kph (62 mph). Any time a leak
DTC is set, the vehicle should be
inspected carefully for evidence of a
leak and should be repaired
immediately. See your dealer.
Brake Fade Warning Assist
The Brake Fade Warning Assist
system monitors the performance of
the brake system. If the system
detects brake fade, or if the brake
fluid is near the boiling point, the
driver will be alerted.
The Brake Fade Warning Assist
system is designed for use with the
factory-installed brake pads or GM
approved replacement pads. If the
brake pads on the vehicle need to be
replaced, use GM approved brakepads. If this is not done, the brake
fade warning system may not function
properly.
Stage 1 :
The DIC displays a “Reduce
Braking to Avoid Overheating”
message, a chime sounds and brake
pedal effort and travel is increased.
When the message displays, the driver
should back up braking points and
reduce brake usage in order to reduce
brake temperature. This will allow for
continued lapping with no speed
limitations.
Stage 2 : The DIC displays a Brakes
Overheated Service Now message, a
chime sounds, and brake pedal effort
and travel is further increased. This
code indicates that the brake fluid
temperature is excessive and is about
to boil. The system limits vehicle
speed to 100 km/h (62 mph). The
driver should immediately start a cool
down lap if on the track. If this
message displays, the vehicle needs to
be serviced. The brake system needs
to cool down, and the brake fluid
must be immediately flushed with
DOT 4 for street use, or to a qualified

DOT 4 race fluid for track use. Boiled
brake fluid is compromised and must
be replaced.
Brake Burnishing
For vehicles equipped with front
Brembo brake systems:
Performance/racing brake pads are
required prior to racing or closed track
driving. Vehicles with option code JE2
have performance brake pads. This
procedure should not be performed on
other models as damage may result.
New brake pads must be burnished
before racing or other competitive
driving.
Caution
Performing the brake burnish
procedure on a base brake system
can result in brake damage.
Caution
The new vehicle break-in period
should be completed before
performing the brake burnish(Continued)
Caution (Continued)
procedure, otherwise damage may
occur to the powertrain/engine. See
New Vehicle Break-In0231.
Caution
Brake 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.
When this procedure is performed as
instructed, it will not damage the
brakes. The brake pads will smoke and
produce an odor. The braking force
and pedal travel may increase. After
the procedure, the brake pads may
appear white at the rotor contact.
Perform this procedure only on dry
pavement, in a safe manner, and in
compliance with all local and state
ordinances/laws regarding motor
vehicle operation. Street High Performance Brake
Burnishing Procedure
This section is for the V-Series
Blackwing with J57 carbon ceramic
brake rotors only.
This procedure should only be run on
a track or other non-public area, and
only on dry pavement.
Caution
Brake 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. From a stop, accelerate as rapidly as possible without activating
traction control to a speed of
100 km/h (60 mph).
2. Using the G-Force Gauge in the HUD display, use enough pedal
force to completely stop the vehicle
in four to five seconds. (~0.7g Decel
level to stop the vehicle in a
straight line). If ABS activates,
braking is too hard.

If the vehicle has an automatic
transmission, and is not in P (Park),
the ignition will return to ACC/
ACCESSORY and display a message in
the Driver Information Center (DIC).
When the vehicle is shifted into
P (Park), the ignition system will
turn OFF.
If the vehicle has a manual
transmission and is stationary, the
ignition will turn off, and Retained Accessory Power (RAP) will remain
active. See
Retained Accessory Power
(RAP) 0237.
The vehicle may have an electric
steering column lock. The lock is
activated when the vehicle is switched
to OFF and the driver door is opened.
A sound may be heard as the lock
actuates or releases. The steering
column lock may not release with the
wheels turned off center. If this
happens, the vehicle may not start.
Move the steering wheel from left to
right while attempting to start the
vehicle. If this does not work, the
vehicle needs service.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake and
steering systems and disable the
airbags.
If the vehicle must be shut off in an
emergency: 1. Brake using a firm and steady pressure. Do not pump the brakes
repeatedly. This may deplete power
assist, requiring increased brake
pedal force. 2. Shift the vehicle to N (Neutral).
This can be done while the vehicle
is moving. After shifting to
N (Neutral), firmly apply the brakes
and steer the vehicle to a safe
location.
3. Come to a complete stop. Shift to P (Park) with an automatic
transmission, or Neutral with a
manual transmission. Turn the
ignition off.
4. Set the parking brake. See Electric
Parking Brake 0254.
{Warning
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the vehicle
off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
press and hold ENGINE START/STOP
for longer than two seconds, or press
twice within five seconds.
