DRIVING AND OPERATING 221
{Warning
Some of the adjustments and
procedures specified in this section
may require specialized skill,
training, and equipment. Failure to
perform these procedures properly
could cause malfunction,
potentially resulting in death,
personal injury, or damage to the
vehicle or property. Do not attempt
to perform these adjustments or
procedures unless properly
qualified.
{Warning
Prior to each track event and again
before returning to public roads,
tighten the wheel nuts with a
torque wrench to the proper torque
specification. Wheel nuts that are
improperly or incorrectly tightened
can cause the wheels to become
loose or come off, resulting in a
crash. SeeCapacities and
Specifications 0426 for wheel nut
torque specifications.
Caution
If the vehicle is used for track
events and competitive driving, the
engine may use more oil than it
would with normal use. Low oil
levels can damage the engine.
Check the oil level often and
maintain the proper level. See
Engine Oil 0336.
Competitive Driving Mode can be
selected. See Driver Mode Control
0 259.
Seat Belts
Lap-Shoulder Belt
If equipped, the driver seat belt has an
Automatic Locking Retractor (ALR).
This feature is useful in performance
driving scenarios where the driver
wants to be held in the seat more
tightly to take advantage of the
aggressive bolstering of the seat.
1. Move the seat 8-10 cm (3-4 in) rearward from the normal driving
position. 2. Pull the driver shoulder belt out as
far as it will go, until it stops, to set
the lock. While holding the
shoulder belt in this position,
buckle the belt.
When the shoulder belt is released,
the retractor will make a ratchet
sound when it retracts. When the
retractor lock is set, the belt can be
tightened but not pulled out of the
retractor.
3. Adjust the belt, and then move the seat forward 8-10 cm (3-4 in) to
the desired driving position. This
will secure the belt. The belt fit
should be tight, but not
uncomfortable.
To unlatch the belt, press the
button on the buckle. The belt
should return to its stowed
position.
Axle Fluid
Axles must have 2 400 km (1,500 mi)
before being used in track driving.
The front, if equipped with AWD, and
rear axle fluid temperatures may be
higher than when driving in severe
conditions. Drain and refill with new

222 DRIVING AND OPERATING
fluid after the first racing or
competitive driving event, and then
after every 24 hours of racing or
competitive driving. See your dealer
for the correct fluid.
Caution
During a first time track or racing
event, high axle temperatures can
occur. Damage could be caused to
the axle and would not be covered
by the vehicle warranty. Do not
drive as long or as fast the first
time the vehicle is driven on the
track or raced.
.The axle lubricant should be
replaced with new lubricant.
.On vehicles without a differential
cooler, additional cooling capacity is
required for continuous competitive
driving. The V-Series Blackwing has
a differential cooler, so no
additional cooling capacity is
necessary.
Engine OilCaution
If the vehicle is used for track
events and competitive driving, the
engine may use more oil than it
would with normal use. Low oil
levels can damage the engine.
Check the oil level often and
maintain the proper level. See
Engine Oil 0336.
Check the oil level often during track
events and competitive driving, and
keep the oil level at or near the upper
mark. See “Checking the Engine Oil" in
Engine Oil 0336.
Fuel
Use premium unleaded gasoline with
a posted octane rating of 93 at a track
event. Unleaded gasoline with a
posted octane rating of 91 may be
used, but performance will be
degraded. See Prohibited Fuels 0317.
Automatic or Manual
Transmission Fluid
Have the transmission fluid set to the
track specific oil level prior to track
usage. Transmission fluid should be
changed after every 15 hours of track
usage. Any transmission level set or
change should be performed at the
dealer.
Brakes
Battery Disconnect
Disconnect the battery before
servicing the hydraulic brake system.
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 may occur when
a door is opened or the remote key is
present.
Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-15268585) -
2022 - CRC - 10/11/21
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.

2022 - CRC - 10/11/21
DRIVING AND OPERATING 225
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
New brake pads must be burnished
before racing or other competitive
driving.Caution
These procedures are specific to the
V-Series with performance brake
linings package. This procedure
should not be run on other models
as damage may result.
Caution
The new vehicle break-in period
should be completed before
performing the brake burnishing
procedure or damage may occur to
the powertrain/engine. See New
Vehicle Break-In 0236.
Caution
Brake pedal fade will occur during
any 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 performed as instructed, these
procedures will not damage the
brakes. During the burnishing procedure, the brake pads will smoke
and produce an odor. The braking
force and pedal travel may increase.
After the procedure is complete, the
brake pads may appear white at the
rotor contact.
Perform these procedures in a safe
manner and in compliance with all
local and state ordinances/laws
regarding motor vehicle operation.
Perform the procedures only on dry
pavement.
As with all high performance brake
systems, some amount of brake squeal
is normal.
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.

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.
