.Try to avoid sudden
steering, acceleration,
or braking, including
reducing vehicle speed by
shifting to a lower gear. Any
sudden changes could cause
the tires to slide.
Remember: Antilock brakes
help avoid only the
braking skid.
Track Events and
Competitive Driving
(V-Series and
V-Series Blackwing)
Before any track event, there
are three features that should
be turned off:
.Automatic Emergency
Braking (AEB). See
Automatic Emergency
Braking (AEB) 0349.
.Lane Keep Assist. See Lane
Keep Assist (LKA) 0356.
.Adaptive Cruise Control. See
Adaptive Cruise Control
(Advanced) 0305.
{Danger
High-performance features
are intended for use only on
closed tracks by
experienced and qualified
drivers and should not be
used on public roads.
High-speed driving,
aggressive cornering, hard
braking, and other
high-performance driving
can be dangerous. Improper
driver inputs for the
conditions may result in loss
of control of the vehicle,
which could injure or kill you
or others. Always drive
safely.
Track events and competitive
driving may affect the vehicle
warranty. See the warranty
manual before using the
vehicle for competitive driving.
{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 (Continued)

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).
Custom Launch Control (If
Equipped)
Custom Launch Control allows
the following parameters for
Launch Control to be modified:
.Launch RPM
.Slip Target (5%–15%)
.Surface Type
To adjust the Launch RPM, all
of these conditions must
be met:
.The vehicle must be in Track
Mode. See “Track Mode”
under Driver Mode Control

the brake pedal to launch
the vehicle.
Line Lock (If Equipped)
{Warning
The vehicle may move
unexpectedly when using
Line Lock, which could cause
injury to persons or property
located nearby. Only use
Line Lock on a closed track
where there is a large clear
(Continued)
Warning (Continued)
area around all sides of the
vehicle. Be ready to apply
the brakes immediately if the
vehicle begins to move. Do
not use Line Lock in an area
that is accessible to the
public or where people or
property are located near
the vehicle.
Caution
Attempting to shift when
the drive wheels are
spinning and do not have
traction may cause damage
to the transmission. Damage
caused by misuse of the
vehicle is not covered by the
vehicle warranty. Do not
attempt to shift when the
drive wheels do not have
traction. Line Lock allows for locking
the front brakes
independently of the rear
brakes. This allows the rear
tires to spin when the throttle
is applied.
To enter Line Lock, all of
these conditions must be met:
.The vehicle must be in
Track Mode.
.Performance Traction
Management (PTM) Mode
must be enabled.
.The steering wheel must be
straight.
.The driver door must be
closed.
.The vehicle must be in D
(Drive) for an automatic
transmission or 1 (First) gear
for a manual transmission.
.The parking brake must not
be engaged.
.The vehicle must be stopped
on level ground. The
accelerator pedal must not
be applied.

258 Driving and Operating
{Warning
Wet brakes can cause
crashes. They might not
work as well in a quick stop
and could cause pulling to
one side. You could lose
control of the vehicle.
After driving through a large
puddle of water or a car/
vehicle wash, lightly apply
the brake pedal until the
brakes work normally.
Flowing or rushing water
creates strong forces.
Driving through flowing
water could cause the
vehicle to be carried away.
If this happens, you and
other vehicle occupants
could drown. Do not ignore
police warnings and be very
cautious about trying to
drive through flowing water.
Caution
Driving through deep
puddles or standing water
can cause water to come in
through the engine air intake
and damage the engine.
If deep puddles or standing
water cannot be avoided,
proceed with caution and do
not exceed 8 km/h (5 mph).
Do not drive through water
that may come close to or
cover the vehicle’s
underbody.
Hydroplaning
Hydroplaning is dangerous.
Water can build up under the
vehicle's tires so they actually
ride on the water. This can
happen if the road is wet
enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.There is no hard and fast rule
about hydroplaning. The best
advice is to slow down when
the road is wet.
Other Rainy Weather Tips
Besides slowing down, other
wet weather driving tips
include:
.Allow extra following
distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer
fluid reservoir filled.
.Have good tires with proper
tread depth. See Tires
0418.
.Turn off cruise control.
Hill and Mountain
Roads
Driving on steep hills or
through mountains is different
than driving on flat or rolling
terrain. Tips include:
.Keep the vehicle serviced
and in good shape.

.Check all fluid levels and
brakes, tires, cooling system,
and transmission.
.Shift to a lower gear when
going down steep or long
hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill
slope can cause brake
overheating, can reduce
brake performance, and
could result in a loss of
braking. Shift the
transmission to a lower gear
to let the engine assist the
brakes on a steep downhill
slope.
{Warning
Coasting downhill in
N (Neutral) or with the
ignition off is dangerous.
This can cause overheating
of the brakes and loss of(Continued)

steering assist. Always have
the engine running and the
vehicle in gear.
.Drive at speeds that keep
the vehicle in its own lane.
Do not swing wide or cross
the center line.
.Be alert on top of hills;
something could be in your
lane (e.g., stalled car, crash).
.Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
Winter Driving
Driving on Snow or Ice
Caution
To avoid damage to the
wheels and brake
components, always clear (Continued)
Caution (Continued)
snow and ice from inside the
wheels and underneath the
vehicle before driving.
Snow or ice between the tires
and the road creates less
traction or grip, so drive
carefully. Wet ice can occur at
about 0 °C (32 °F) when
freezing rain begins to fall.
Avoid driving on wet ice or in
freezing rain until roads can be
treated.
For Slippery Road Driving:
.Accelerate gently.
Accelerating too quickly
causes the wheels to spin
and makes the surface under
the tires slick.
.Turn on Traction Control.
See Traction Control/
Electronic Stability Control
0 291.
.The Antilock Brake System
(ABS) improves vehicle
stability during hard stops,
but the brakes should be

Driving and Operating 261
To save fuel, run the engine
for short periods to warm the
vehicle and then shut the
engine off and partially close
the window. Moving about to
keep warm also helps.
If it takes time for help to
arrive, when running the
engine, push the accelerator
pedal slightly so the engine
runs faster than the idle
speed. This keeps the battery
charged to restart the vehicle
and to signal for help with the
headlamps. Do this as little as
possible, to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle
when stuck in sand, mud, ice,
or snow.
The Traction Control System
(TCS) can often help to free a
stuck vehicle. See Traction
Control/Electronic Stability
Control0291. If TCS cannot free the vehicle,
turn TCS off and use the
rocking method. See
“Rocking
the Vehicle to Get it Out”
following.
{Warning
If the vehicle's tires spin at
high speed, they can
explode, and you or others
could be injured. The vehicle
can overheat, causing an
engine compartment fire or
other damage. Spin the
wheels as little as possible
and avoid going above
56 km/h (35 mph).
Rocking the Vehicle to Get
it Out
Turn the steering wheel left
and right to clear the area
around the front wheels. Turn
off any traction system. Shift
back and forth between
R (Reverse) and a low forward
gear, spinning the wheels as
little as possible. To prevent
transmission wear, wait until the wheels stop spinning
before shifting gears. Release
the accelerator pedal while
shifting, and press lightly on
the accelerator pedal when
the transmission is in gear.
Slowly spinning the wheels in
the forward and reverse
directions causes a rocking
motion that could free the
vehicle. If that does not get
the vehicle out after a few
tries, it might need to be
towed out. If the vehicle does
need to be towed out, see
Transporting a Disabled
Vehicle
0455.
Vehicle Load Limits
It is very important to know
how much weight the
vehicle can carry. This
weight is called the vehicle
capacity weight and
includes the weight of all
occupants, cargo, and all
nonfactory-installed
options. Two labels on the
vehicle may show how

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -
2023 - CRC - 5/10/22
262 Driving and Operating
much weight it may
properly carry: the Tire and
Loading Information label
and the Certification label.
{Warning
Do not load the vehicle
any heavier than the
Gross Vehicle Weight
Rating (GVWR), or either
the maximum front or
rear Gross Axle Weight
Rating (GAWR). This can
cause systems to break
and change the way the
vehicle handles. This
could cause loss of
control and a crash.
Overloading can also
reduce stopping
performance, damage the
tires, and shorten the life
of the vehicle. Tire and Loading
Information Label
Label Example
A vehicle-specific Tire and
Loading Information label is
attached to the vehicle's
center pillar (B-pillar). The
Tire and Loading
Information label shows the
number of occupant
seating positions (1), and
the maximum vehicle
capacity weight (2) in
kilograms and pounds. The Tire and Loading
Information label also
shows the tire size of the
original equipment tires (3)
and the recommended cold
tire inflation pressures (4).
For more information on
tires and inflation see Tires
0
418 and
Tire Pressure 0427.
There is also important
loading information on the
Certification label. It may
show the Gross Vehicle
Weight Rating (GVWR) and
the Gross Axle Weight
Rating (GAWR) for the
front and rear axle. See
“Certification Label” later in
this section.
