224 DRIVING AND OPERATING
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 inspectedcarefully 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.

DRIVING AND OPERATING 237
Caution (Continued)
lower gear. This rule applies at all
times, not just during the
break-in period.
.Do not participate in racing
events, sport driving schools,
or similar activities during this
break-in period.
.Check engine oil with every
refueling and add if necessary.
Oil and fuel consumption may be
higher than normal during the
first 2 414 km (1,500 mi).
.To break in new tires, drive at
moderate speeds and avoid hard
cornering for the first
322 km (200 mi). New tires do
not have maximum traction and
may tend to slip.
.New brake linings also need a
break-in period. Avoid making
hard stops during the first
322 km (200 mi). This is
recommended every time brake
linings are replaced.(Continued)
Caution (Continued)
.Should the vehicle be used for
racing or competitive driving
(after break-in), the rear axle
lubricant must be replaced
beforehand.
See Track Events and Competitive
Driving (V-Series and V-Series
Blackwing) 0220.
On new vehicles, the various
mechanical and electrical systems
experience a “break-in”period during
the first 6,400 km (4,000 miles) of
routine driving. As the vehicle is
driven, the mechanical systems adjust
to provide optimal fuel economy and
transmission shift performance.
Electrical systems will adapt and
calibrate during the break-in period.
A one-time occurrence of clicks and
similar vehicle noises is normal during
this process.
Normal driving charges the vehicle’s
battery to achieve the best operation
of the vehicle, including fuel economy.
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.
{Warning
Exposed edges of parts containing
carbon fiber and other composite
materials can be sharp. Contact
with these parts could result in
injury. Use caution to avoid
contacting these parts, including
when washing the vehicle. If the
parts are damaged, replace the
parts promptly with replacements
from your dealer.
{Warning
Rocker extensions may break under
pressure, resulting in property
damage or injury. Do not stand on
the rocker extension or use it as
a step.

VEHICLE CARE 353
The brake/clutch master cylinder
reservoir is filled with GM approved
DOT 4 brake fluid as indicated on the
reservoir cap. SeeEngine Compartment
Overview 0331 for the location of the
reservoir.
Checking Brake Fluid
Place the vehicle in P (Park) or
Neutral with the parking brake applied
if equipped with a manual
transmission. On a level surface, the
brake fluid level should be between
the minimum and maximum marks
on the brake fluid reservoir.
There are only two reasons why the
brake fluid level in the reservoir may
go down:
.Normal brake lining wear. When
new linings are installed, the fluid
level goes back up.
.A fluid leak in the brake/clutch
hydraulic system. Have the brake/
clutch hydraulic system fixed. With
a leak, the brakes will not work well.
Always clean the brake fluid reservoir
cap and the area around the cap
before removing it. Do not top off the brake/clutch fluid.
Adding fluid does not correct a leak.
If fluid is added when the linings are
worn, there will be too much fluid
when new brake linings are installed.
Add or remove fluid, as necessary,
only when work is done on the brake/
clutch hydraulic system.
{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You or
others could be burned, and the
vehicle could be damaged. Add
brake fluid only when work is done
on the brake/clutch hydraulic
system.
When the brake/clutch fluid falls to a
low level, the brake warning light
comes on. See Brake System Warning
Light 0108.
Brake fluid absorbs water over time
which degrades the effectiveness of
the brake fluid. Replace brake fluid at
the specified intervals to prevent
increased stopping distance. See
Maintenance Schedule 0410. What to Add
Use only GM approved DOT 4 brake
fluid from a clean, sealed container.
See
Recommended Fluids and
Lubricants 0420.
{Warning
The wrong or contaminated brake
fluid could result in damage to the
brake system. This could result in
the loss of braking leading to a
possible injury. Always use the
proper GM approved brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces, the paint
finish can be damaged. Immediately
wash off any painted surface.
Battery - North America
The original equipment battery is
maintenance free. Do not remove the
cap and do not add fluid.
Refer to the replacement number
shown on the original battery label
when a new battery is needed.

transfer case fluid does not require
maintenance unless there is a fluid
leak or unusual noise. If required,
have the transfer case serviced by
your dealer.
Park Brake and P (Park)
Mechanism Check
{Warning
When you are doing this check, the
vehicle could begin to move. You or
others could be injured and
property could be damaged. Make
sure there is room in front of the
vehicle in case it begins to roll. Be
ready to apply the regular brake at
once should the vehicle begin
to move.

380 VEHICLE CARE
.There is a malfunction in the horn
or turn signal lamps.
.The identification code of the TPMS
sensor is not registered to the
system.
.The battery of the TPMS sensor
is low.
If the tire fill alert does not operate
due to TPMS interference, move the
vehicle about 1 m (3 ft) back or
forward and try again. If the tire fill
alert feature is not working, use a tire
pressure gauge.
TPMS Sensor Matching Process
— Auto Learn Function
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a new
tire/wheel position after rotating the
tires or replacing one or more of the
TPMS sensors. When a tire is
installed, the vehicle must be
stationary for about 20 minutes before
the system recalculates. The following
relearn process takes up to
10 minutes, driving at a minimum
speed of 20 km/h (12 mph). A dash (-)
or pressure value will display in the DIC. See
Driver Information Center
(DIC) (Base Level) 0116 or
Driver Information Center (DIC)
(Uplevel) 0119. A warning message
displays in the DIC if a problem
occurs during the relearn process.
Tire Inspection
We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected for
signs of wear or damage at least
once a month.
Replace the tire if:
.The indicators at three or more
places around the tire can
be seen.
.There is cord or fabric showing
through the tire's rubber.
.The tread or sidewall is cracked,
cut, or snagged deep enough to
show cord or fabric.
.The tire has a bump, bulge,
or split.
.The tire has a puncture, cut,
or other damage that cannot be
repaired well because of the size
or location of the damage.
Tire Rotation
Tires should be rotated every
12 000 km (7,500 mi). See
Maintenance Schedule 0410.
Tires are rotated to achieve a
more uniform wear for all tires.
The first rotation is the most
important.
Anytime unusual wear is noticed,
rotate the tires as soon as
possible, check for proper tire
inflation pressure, and check for
damaged tires or wheels. If the
unusual wear continues after the
rotation, check the wheel
alignment. See When It Is Time for
New Tires 0382 and
Wheel Replacement 0386.
Different tire sizes should not be
rotated front to rear.
