2. Using the G-Force Gaugein 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.
3. Repeat the first two steps 20 consecutive times, this
should take about
five minutes.
4. After completing the 20 stops, cool the brakes by
driving for 8 km (5 mi) at
100 km/h (60 mph).
Alternative Closed Course
Brake Burnishing Procedure
This brake burnish procedure
should only be run on vehicles
with a 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.

Tire Inflation Pressure
Guidelines
Tire inflation pressures affect
vehicle handling and tire life,
and should be adjusted for
various types of tracks/
courses.
Inspect the tires prior to every
track/course session. Track/
course driving will reduce the
tire tread life.
To maximize tire life, drive
800 km (500 mi) prior to
racetrack driving or complete
the minimum track running
that will increase the tire
pressures by 35 kPa (5 psi).
After this, immediately let the
tires cool to cold pressures.

Tire Inflation Pressure for
Track Driving
For driving on a race course,
if the vehicle is equipped with
275/35ZR19 (100Y) and
305/30ZR19 (102Y) tires, set
the cold (stationary) tire
pressures to 28 psi. During
track sessions, set the tire
pressures at 35 to 38 psi for
hot tires. If pressures exceed
38 psi, adjust the pressures
down to 35 to 38 psi. Return
the tires to the recommended
cold tire inflation pressure
when track driving has ended.
Driving and Operating
{Warning
Operating the vehicle at high
speeds can be dangerous.
Improper tire inflation
pressure can put additional (Continued)
Warning (Continued)
strain on the tires and can
cause a sudden failure. Make
sure the tires are in
excellent condition, and use
the correct cold tire inflation
pressure for the vehicle load
and track/course.
{Warning
Tracks/courses put high
loads on tires operating at
high speed, which can lead
to tire failure if not inflated
properly. Always limit vehicle
cargo to the driver plus one
passenger with no additional
cargo.
{Warning
Track/course loads wear
tires both on the tread and
internal to the tire. When
driven in track/course(Continued)
Warning (Continued)
conditions, even if tread is
not worn down to the
treadwear indicator, tires
must be replaced after the
equivalent of two tanks of
fuel or approximately 160 km
(100 mi).

All-Season Tires
This vehicle may come with
all-season tires. These tires
are designed to provide good
overall performance on most
road surfaces and weather
conditions. Original equipment
tires designed to GM's specific
tire performance criteria have
a TPC specification code
molded onto the sidewall.
Original equipment all-season
tires can be identified by the
last two characters of this
TPC code, which will be “MS.”
Consider installing winter tires
on the vehicle if frequent
driving on snow or ice-covered
roads is expected. All-season
tires provide adequate
performance for most winter
driving conditions, but they
may not offer the same level of traction or performance as
winter tires on snow or
ice-covered roads. See Winter
Tires
0419.
Winter Tires
This vehicle was not originally
equipped with winter tires.
Winter tires are designed for
increased traction on snow
and ice-covered roads.
Consider installing winter tires
on the vehicle if frequent
driving on ice or snow covered
roads is expected. See your
dealer for details regarding
winter tire availability and
proper tire selection. Also, see
Buying New Tires 0437.
With winter tires, there may
be decreased dry road
traction, increased road noise,
and shorter tread life. After
changing to winter tires, be
alert for changes in vehicle
handling and braking.

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -
2023 - CRC - 5/6/22
420 Vehicle Care
If using winter tires:
.Use tires of the same brand
and tread type on all four
wheel positions.
.Use only radial ply tires of
the same size, load range,
and speed rating as the
original equipment tires.
Winter tires with the same
speed rating as the original
equipment tires may not be
available for H, V, W, Y, and ZR
speed rated tires. If winter
tires with a lower speed rating
are chosen, never exceed the
tire's maximum speed
capability.
Run-Flat Tires
This vehicle, when new, may
have had run-flat tires. There
is no spare tire, no tire
changing equipment, and no
place to store a tire in the
vehicle.
{Warning
While driving with run-flat
tires at a reduced inflation
pressure, avoid making
sudden stops or severe
maneuvers as the handling
capabilities of the tires will
be reduced. Driving too fast
could cause loss of control
and you or others could be
injured. Do not drive over
80 km/h (50 mph) with the
tire operating at low
pressure. Drive cautiously
and check the tire pressure
as soon as possible.
Run-flat tires can be driven up
to 80 km (50 mi) at speeds
less than 80 km/h (50 mph)
after a loss of inflation
pressure has occurred. There
is no need to stop on the side
of the road to change the tire.
The possible driving range
after a pressure loss will vary
based on the vehicle load and
driving conditions. As soon as possible, contact the nearest
authorized GM or run-flat
servicing facility for inspection
and repair or replacement.
When driving on a deflated
run-flat tire, avoid potholes
and other road hazards that
could damage the tire and/or
wheel beyond repair. When a
tire has been damaged, or if
driven any distance while
deflated, check with an
authorized run-flat tire service
center to determine whether
the tire can be repaired or
should be replaced. To
maintain the run-flat feature,
all replacement tires must be
run-flat tires.
To locate the nearest GM or
run-flat servicing facility, call
Customer Assistance.
Self-Sealing Tires
This vehicle may have
self-sealing tires. These tires
have a material inside that can
seal punctures from common
road hazards, such as nails

Vehicle Care 421
and screws, in the tread area.
The tire may lose air pressure
if the sidewall is damaged or
the tread puncture is too
large. If the Tire Pressure
Monitor System indicates the
tire pressure is low, inspect
the tire for damage and inflate
it to the recommended
pressure. If the tire is unable
to maintain the recommended
pressure, contact the nearest
authorized GM servicing
facility immediately for
inspection and repair or
replacement. To locate the
nearest GM servicing facility,
call GM Customer Assistance.
Caution
Do not drive on a deflated
self-sealing tire as this could
damage the tire. Make sure
the tire is inflated to the
recommended pressure or
have it immediately repaired
or replaced.When tire replacement is
needed replace with a
self-sealing tire, because the
vehicle does not come with a
spare tire or tire changing
equipment.
Noise Reducing Tires
(V-Series
Blackwing Only)
This vehicle may be equipped
with tires that have
noise-absorbing foam
technology to reduce road and
interior noise levels.
