along with the system’s voice
recognition database. This
allows you to speak more
naturally when using voice
recognition.
Using Voice Recognition
Voice recognition becomes
available once the system has
been initialized. This begins
when the ignition is turned on.
Initialization may take a few
moments.1. Press
gon the steering
wheel controls to activate
voice recognition.
2. The audio system mutes and the system plays a
prompt.
3. Clearly speak one of the commands described in
this section.
A voice recognition system
prompt can be interrupted
while it is playing by
pressing
gagain. Once voice recognition is
started, both the infotainment
display and instrument cluster
show the selections and visual
dialog content. These displays
can be turned on or off in the
Tutorial Mode under Settings
0
207.
There are three voice prompt
modes supported:
.Informative verbal prompts:
This type of prompt will
provide more information
regarding the supported
actions.
.Short prompts: This type of
prompt will provide simple
instructions about what can
be stated.
.Auto informative prompts:
This type of prompt plays
during the first few speech
sessions, then automatically
switches to the short
prompt after some
experience has been gained
through using the system. If a command is not spoken,
the voice recognition system
says a help prompt.
Prompts and Infotainment
Displays
While a voice recognition
session is active, there may be
corresponding options
showing on the displays.
A selection can be made by
manually touching the option,
or by speaking the number for
the option to select. Manual
interaction in the voice
recognition session is
permitted. Interaction during a
voice session may be
completed entirely using voice
commands while some manual
commands may expedite a
task. If a selection is made
using a manual control, the
voice recognition dialog will
progress in the same way as if
the selection were made using
a voice command. Once the
system completes the task,

Similar limits exist for album
content. If there are more than
12,000 albums, but fewer than
24,000, the content cannot be
accessed directly with one
command like,“Play name>.” The command “Play
Album” must first be spoken;
the system will then ask for
the album name. The reply
would be to say the name of
the album to play.
Once the number of files has
exceeded approximately
24,000, there is no support
for accessing the songs
directly through voice
commands. There will still be
access to the media content
by using commands for
playlists, artists, and genres.
The access commands for
playlists, artists, and genres
are prohibited after the
number of this type of media
exceeds 12,000.
The system will provide
feedback the first time voice
recognition is initiated if it has become apparent that any of
these limits are reached
during a device initializing
process.
Voice recognition
performance will degrade to
some extent based on many
factors when adding large
amounts of data to recognize.
If this is the case, perhaps
accessing songs through
playlists or artist name would
work better.

.Maintain a reasonable
steady speed through the
curve.
.Wait until the vehicle is out
of the curve before
accelerating gently into the
straightaway.
Steering in Emergencies
.There are some situations
when steering around a
problem may be more
effective than braking.
.Holding both sides of the
steering wheel allows you to
turn 180 degrees without
removing a hand.
.The Antilock Brake System
(ABS) allows steering while
braking.
Off-Road Recovery
The vehicle's right wheels can
drop off the edge of a road
onto the shoulder while
driving. Follow these tips:1. Ease off the accelerator and then, if there is
nothing in the way, steer
the vehicle so that it
straddles the edge of the
pavement.
2. Turn the steering wheel about one-eighth of a turn,
until the right front tire
contacts the
pavement edge. 3. Turn the steering wheel to
go straight down the
roadway.
Loss of Control
Skidding
There are three types of skids
that correspond to the
vehicle's three control
systems:
.Braking Skid —wheels are
not rolling.
.Steering or Cornering Skid —
too much speed or steering
in a curve causes tires to slip
and lose cornering force.
.Acceleration Skid —too
much throttle causes the
driving wheels to spin.
Defensive drivers avoid most
skids by taking reasonable
care suited to existing
conditions, and by not
overdriving those conditions.
But skids are always possible.

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 High
Speed
See Tire Pressure for
High-Speed Operation
0423.
Tire Inflation Pressure for
Track Driving
For driving on a race course,
if your vehicle is equipped with
255/35ZR18 (94Y) and
275/35ZR18 (99Y) tires, set
cold (stationary) tire pressures
to 30 psi. During track
sessions, set the pressures at
35 to 38 psi for hot tire
pressures. If pressures exceed
38 psi, bleed pressures down

2023 - CRC - 5/10/22
248 Driving and Operating
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
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(Continued)
Warning (Continued)
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
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
0 292.
.Performance Traction
Management (PTM) Mode
must be enabled. See Driver
Mode Control 0292.
.The steering wheel must be
straight.
.The driver door must be
closed.
.The transmission must be in
D (Drive) or forward gear.
.The parking brake must not
be engaged.

If a cargo carrier is used in the
trailer hitch receiver, choose a
carrier that positions the load
as close to the vehicle as
possible. Make sure the total
weight, including the carrier, is
no more than half of the
maximum allowable tongue
weight for the vehicle or
227 kg (500 lb), whichever
is less.
Ask your dealer for trailering
information or assistance.
Towing Equipment
Hitches
Always use the correct hitch
equipment for your vehicle.
Crosswinds, large trucks going
by, and rough roads can affect
the trailer and the hitch.
Never attach rental hitches or
other bumper-type hitches.
Only use frame-mounted
hitches that do not attach to
the bumper.Always seal any holes in your
vehicle if the trailer hitch
removed. If not sealed, dirt,
water, and carbon monoxide
(CO) from the exhaust may
enter your vehicle. See Engine
Exhaust
0271.
Consider using mechanical
sway controls with any trailer.
Ask a trailering professional
about sway controls or refer
to the trailer manufacturer's
recommendations and
instructions.
Tires
.Do not tow a trailer while
using a compact spare tire
on the vehicle.
.Tires must be properly
inflated to support loads
while towing a trailer. See
Tires 0413 for instructions
on proper tire inflation.
Safety Chains
Always attach chains between
the vehicle and the trailer, and
attach the chains to the holes
on the trailer hitch platform.
Instructions about safety
chains may be provided by the
hitch manufacturer or by the
trailer manufacturer.
Cross the safety chains under
the tongue of the trailer to
help prevent the tongue from
contacting the road if it
becomes separated from the
hitch. Always leave just
enough slack so the
combination can turn. Never
allow safety chains to drag on
the ground.

Vehicle Care 415
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

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-16500442) -
2023 - CRC - 5/4/22
416 Vehicle Care
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.
Low-Profile Tires
If the vehicle has
225/45R17 91V,
235/40R18 91V,
235/40R18 XL 95Y,
or 235/35R19 XL 91V,
255/35ZR18 (94Y),
or 275/35ZR18 (99Y) size
tires, they are classified as
low-profile tires.
Caution
Low-profile tires are more
susceptible to damage from
road hazards or curb impact
than standard profile tires.
Tire and/or wheel assembly
damage can occur when
coming into contact with
road hazards like potholes, (Continued)
Caution (Continued)
or sharp edged objects,
or when sliding into a curb.
The warranty does not
cover this type of damage.
Keep tires set to the correct
inflation pressure and when
possible, avoid contact with
curbs, potholes, and other
road hazards.
Summer Tires
High Performance Summer
Tires
This vehicle may come with
235/40R18 XL 95Y,
255/35ZR18 (94Y),
or 275/35ZR18 (99Y) high
performance summer tires.
These tires have a special
tread and compound that are
optimized for maximum dry
and wet road performance.
This special tread and
compound will have decreased
performance in cold climates,
and on ice and snow. It is
recommended that winter

Vehicle Care 417
tires be installed on the
vehicle if frequent driving at
temperatures below
approximately 5 °C (40 °F) or
on ice or snow covered roads
is expected. See Winter Tires
0414.
Caution
High performance summer
tires have rubber
compounds that lose
flexibility and may develop
surface cracks in the tread
area at temperatures below
−7 °C (20 °F). Always store
high performance summer
tires indoors and at
temperatures above −7 °C
(20 °F) when not in use. If the
tires have been subjected to
−7 °C (20 °F) or less, let them
warm up in a heated space
to at least 5 °C (40 °F) for
24 hours or more before
being installed or driving a
vehicle on which they are
installed. Do not apply heat
(Continued)
Caution (Continued)
or blow heated air directly
on the tires. Always inspect
tires before use. See Tire
Inspection0429.
Tire Sidewall Labeling
Useful information about a
tire is molded into its
sidewall. The example
shows a typical passenger
tire sidewall.
Passenger Tire Example
(1) Tire Size:The tire size
is a combination of letters
and numbers used to
define a particular tire's
width, height, aspect ratio,
construction type, and
service description. See the
“Tire Size” illustration later
in this section.
(2) TPC Spec (Tire
Performance Criteria
Specification)
:Original
equipment tires designed
to GM's specific tire
performance criteria have a
TPC specification code
molded onto the sidewall.
GM's TPC specifications
meet or exceed all federal
safety guidelines.
(3) DOT (Department of
Transportation)
:The
Department of
Transportation (DOT) code
indicates that the tire is in
compliance with the U.S.
