Check with your dealer
before adding equipment to
the outside of the vehicle.
.Do not attach any devices to
the air vent slats. This
restricts airflow and may
cause damage to the air
vents.
Maintenance
Passenger
Compartment Air
Filter
The filter reduces dust, pollen,
and other airborne irritants
from outside air that is pulled
into the vehicle. The filter
should be replaced as part of
routine scheduled
maintenance. See
Maintenance Schedule0471.
See your dealer regarding
replacement of the filter.
Service
All vehicles have a label
underhood that identifies the
refrigerant used in the vehicle.
The refrigerant system should
only be serviced by trained
and certified technicians. The
air conditioning evaporator
should never be repaired or
replaced by one from a
salvage vehicle. It should only
be replaced by a new
evaporator to ensure proper
and safe operation.
During service, all refrigerants
should be reclaimed with
proper equipment. Venting
refrigerants directly to the
atmosphere is harmful to the
environment and may also
create unsafe conditions
based on inhalation,
combustion, frostbite, or other
health-based concerns.
The air conditioning system
requires periodic maintenance.
See Maintenance Schedule
0 471.

self diagnostic tests that may
occur when a door is opened
or the remote key is present.
{Warning
To avoid personal injury and/
or vehicle damage, always
disconnect the battery
before performing service
work on the hydraulic brake
system. Bleeding the brake
system with the battery
connected can lead to
excessive pressurization of
the system during automatic
diagnostic tests or diagnosis
of a leak or air in the braking
system. A Diagnostic
Trouble Code (DTC) may set
and vehicle speed may be
limited.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.
4. Remove front tire deflector (if equipped).
If improved brake cooling is
desired on vehicles with
cast-iron brakes (RPO JGH),
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 the
original front and rear rotor
shields and remove the rear
lower control arm cooling
deflectors.

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)
0 403. 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.
It is critical to 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 can possibly 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 J56 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
brake pads. 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.
