Using the DIC, tire pressure
levels can be viewed. For
additional information and
details about the DIC
operation and displays see
Driver Information Center
(DIC)0139.
The low tire pressure warning
light may come on in cool
weather when the vehicle is
first started, and then turn off
as the vehicle is driven. This
could be an early indicator
that the air pressure is getting
low and needs to be inflated to
the proper pressure.
A Tire and Loading
Information label, attached to
your vehicle, shows the size of
the original equipment tires
and the correct inflation
pressure for the tires when
they are cold. See Vehicle
Load Limits 0247, for an
example of the Tire and
Loading Information label and
its location. Also see Tire
Pressure 0384. The TPMS can warn about a
low tire pressure condition but
it does not replace normal tire
maintenance. See Tire
Inspection
0392, Tire Rotation
0 393, and Tires 0376.
Caution
Tire sealant materials are
not all the same.
A non-approved tire sealant
could damage the TPMS
sensors. TPMS sensor
damage caused by using an
incorrect tire sealant is not
covered by the vehicle
warranty. Always use only
the GM approved tire
sealant available through
your dealer or included in
the vehicle.
TPMS Malfunction Light
and Message
The TPMS will not function
properly if one or more of the
TPMS sensors are missing or
inoperable. When the system
detects a malfunction, the low tire pressure warning light
flashes for about one minute
and then stays on for the
remainder of the ignition cycle.
A DIC warning message also
displays. The malfunction light
and DIC warning message
come on at each ignition cycle
until the problem is corrected.
Some of the conditions that
can cause these to come
on are:
.One of the road tires has
been replaced with the
spare tire. The spare tire
does not have a TPMS
sensor. The malfunction light
and DIC message should go
off after the road tire is
replaced and the sensor
matching process is
performed successfully. See
“TPMS Sensor Matching
Process”
later in this section.
.The TPMS sensor matching
process was not done or not
completed successfully after
rotating the tires. The
malfunction light and the DIC
message should go off after

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16406251) - 2023 - CRC - 3/28/22
390 Vehicle Care
successfully completing the
sensor matching process.
See "TPMS Sensor Matching
Process" later in this section.
.One or more TPMS sensors
are missing or damaged. The
malfunction light and the DIC
message should go off when
the TPMS sensors are
installed and the sensor
matching process is
performed successfully. See
your dealer for service.
.Replacement tires or wheels
do not match the original
equipment tires or wheels.
Tires and wheels other than
those recommended could
prevent the TPMS from
functioning properly. See
Buying New Tires0395.
.Operating electronic devices
or being near facilities using
radio wave frequencies
similar to the TPMS could
cause the TPMS sensors to
malfunction. If the TPMS is not functioning
properly it cannot detect or
signal a low tire pressure
condition. See your dealer for
service if the TPMS
malfunction light and DIC
message come on and stay on.
Tire Fill Alert (If Equipped)
This feature provides visual
and audible alerts outside the
vehicle to help when inflating
an underinflated tire to the
recommended cold tire
pressure.
When the low tire pressure
warning light comes on:
1. Park the vehicle in a safe, level place.
2. Set the parking brake firmly.
3. Place the vehicle in P (Park).
4. Add air to the tire that is underinflated. The turn
signal lamp will flash. When the recommended
pressure is reached, the
horn sounds once and the
turn signal lamp will stop
flashing and briefly turn
solid.
Repeat these steps for all
underinflated tires that have
illuminated the low tire
pressure warning light.
{Warning
Overinflating a tire could
cause the tire to rupture
and you or others could be
injured. Do not exceed the
maximum pressure listed on
the tire sidewall. See Tire
Sidewall Labeling 0378 and
Vehicle Load Limits 0247.
If the tire is overinflated by
more than 35 kPa (5 psi), the
horn will sound multiple times
and the turn signal lamp will
continue to flash for several
seconds after filling stops. To
release and correct the
pressure, while the turn signal

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16406251) - 2023 - CRC - 3/28/22
Vehicle Care 391
lamp is still flashing, briefly
press the center of the valve
stem. When the recommended
pressure is reached, the horn
sounds once.
If the turn signal lamp does
not flash within 15 seconds
after starting to inflate the
tire, the tire fill alert has not
been activated or is not
working.
If the hazard warning flashers
are on, the tire fill alert visual
feedback will not work
properly.
The TPMS will not activate the
tire fill alert properly under the
following conditions:
.There is interference from
an external device or
transmitter.
.The air pressure from the
inflation device is not
sufficient to inflate the tire.
.There is a malfunction in
the TPMS.
.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
Each TPMS sensor has a
unique identification code. The
identification code needs to be
matched to a new tire/wheel
position after rotating the
vehicle’s tires or replacing one
or more of the TPMS sensors.
The TPMS sensor matching
process should also be
performed after replacing a
spare tire with a road tire
containing the TPMS sensor.
The malfunction light and the DIC message should go off at
the next ignition cycle. The
sensors are matched to the
tire/wheel positions, using a
TPMS relearn tool, in the
following order: driver side
front tire, passenger side front
tire, passenger side rear tire,
and driver side rear. See your
dealer for service or to
purchase a relearn tool.
A TPMS relearn tool can also
be purchased. See Tire
Pressure Monitor Sensor
Activation Tool at www.
gmtoolsandequipment.com or
call 1-800-GM TOOLS
(1-800-468-6657).
There are two minutes to
match the first tire/wheel
position, and five minutes
overall to match all four tire/
wheel positions. If it takes
longer, the matching process
stops and must be restarted.
The TPMS sensor matching
process is:
1. Set the parking brake.

394 Vehicle Care
{Warning
Rust or dirt on a wheel,
or on the parts to which it
is fastened, can cause
wheel nuts to become
loose over time. The
wheel could come off and
cause a crash. When
changing a wheel, remove
any rust or dirt from
places where the wheel
attaches to the vehicle. In
an emergency, a cloth or
paper towel can be used;
however, use a scraper
or wire brush later to
remove all rust or dirt.
Lightly coat the inner
diameter of the wheel hub
opening with wheel bearing
grease after a wheel
change or tire rotation to
prevent corrosion or rust
buildup.{Warning
Do not apply grease to
the wheel mounting
surface, wheel conical
seats, or the wheel nuts
or bolts. Grease applied
to these areas could
cause a wheel to become
loose or come off,
resulting in a crash.
When It Is Time for
New Tires
Factors, such as maintenance,
temperatures, driving speeds,
vehicle loading, and road
conditions affect the wear
rate of the tires.
Treadwear indicators are one
way to tell when it is time for
new tires. Treadwear
indicators appear when the
tires have only 1.6 mm (1/16 in)
or less of tread remaining. See
Tire Inspection 0392 and
Tire Rotation 0393.
The rubber in tires ages over
time. This also applies to the
spare tire, if the vehicle has
one, even if it is never used.
Multiple factors including
temperatures, loading
conditions, and inflation
pressure maintenance affect
how fast aging takes place.

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16406251) - 2023 - CRC - 3/28/22
396 Vehicle Care
performance may be
adversely affected if all the
tires are not replaced at
the same time. If proper
rotation and maintenance
have been done, all four
tires should wear out at
about the same time.
However, if it is necessary
to replace only one axle set
of worn tires, place the
new tires on the rear axle.
See Tire Rotation0393.
{Warning
Tires could explode
during improper service.
Attempting to mount or
dismount a tire could
cause injury or death.
Only your dealer or
authorized tire service
center should mount or
dismount the tires.
{Warning
Mixing tires of different
sizes (other than those
originally installed on the
vehicle), brands, tread
patterns, or types may
cause loss of vehicle
control, resulting in a
crash or other vehicle
damage. Use the correct
size, brand, and type of
tire on all wheels.
{Warning
Using bias-ply tires on
the vehicle may cause the
wheel rim flanges to
develop cracks after
many miles of driving.
A tire and/or wheel could
fail suddenly and cause a
crash. Use only radial-ply
tires with the wheels on
the vehicle. 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. Never
exceed the winter tires’
maximum speed capability
when using winter tires
with a lower speed rating.
If the vehicle tires must be
replaced with a tire that
does not have a TPC Spec
number, make sure they
are the same size, load
range, speed rating, and
construction (radial) as the
original tires.
The Tire and Loading
Information label indicates
the original equipment tires
on the vehicle. See Vehicle
Load Limits
0247.

Vehicle Care 397
Different Size Tires
and Wheels
If wheels or tires are installed
that are a different size than
the original equipment wheels
and tires, vehicle performance,
including its braking, ride and
handling characteristics,
stability, and resistance to
rollover may be affected. If the
vehicle has electronic systems
such as antilock brakes,
rollover airbags, traction
control, electronic stability
control, or All-Wheel Drive, the
performance of these systems
can also be affected.
{Warning
If different sized wheels are
used, there may not be an
acceptable level of
performance and safety if
tires not recommended for
those wheels are selected.
This increases the chance of
a crash and serious injury.(Continued)
Warning (Continued)
Only use GM specific wheel
and tire systems developed
for the vehicle, and have
them properly installed by a
GM certified technician.
See Buying New Tires 0395
and Accessories and
Modifications 0338.
Uniform Tire Quality
Grading
The following information
relates to the system
developed by the United
States National Highway
Traffic Safety
Administration (NHTSA),
which grades tires by
treadwear, traction, and
temperature performance.
This applies only to
vehicles sold in the United
States. The grades are
molded on the sidewalls of
most passenger car tires. The Uniform Tire Quality
Grading (UTQG) system
does not apply to deep
tread, winter tires, compact
spare tires, tires with
nominal rim diameters of
10 to 12 inches
(25 to 30 cm), or to some
limited-production tires.
While the tires available on
General Motors passenger
cars and light trucks may
vary with respect to these
grades, they must also
conform to federal safety
requirements and
additional General Motors
Tire Performance Criteria
(TPC) standards.
Quality grades can be
found where applicable on
the tire sidewall between
tread shoulder and
maximum section width.
For example:

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16406251) - 2023 - CRC - 3/28/22
398 Vehicle Care
Treadwear 200 Traction AA
Temperature A
All Passenger Car Tires
Must Conform to Federal
Safety Requirements In
Addition To These Grades.
Treadwear
The treadwear grade is a
comparative rating based
on the wear rate of the tire
when tested under
controlled conditions on a
specified government test
course. For example, a tire
graded 150 would wear one
and one-half (1½) times as
well on the government
course as a tire graded
100. The relative
performance of tires
depends upon the actual
conditions of their use,
however, and may depart
significantly from the norm
due to variations in drivinghabits, service practices
and differences in road
characteristics and climate.
Traction
The traction grades, from
highest to lowest, are AA,
A, B, and C. Those grades
represent the tire's ability
to stop on wet pavement
as measured under
controlled conditions on
specified government test
surfaces of asphalt and
concrete. A tire marked C
may have poor traction
performance. Warning: The
traction grade assigned to
this tire is based on
straight-ahead braking
traction tests, and does not
include acceleration,
cornering, hydroplaning,
or peak traction
characteristics.
Temperature
The temperature grades
are A (the highest), B, and
C, representing the tire's
resistance to the
generation of heat and its
ability to dissipate heat
when tested under
controlled conditions on a
specified indoor laboratory
test wheel. Sustained high
temperature can cause the
material of the tire to
degenerate and reduce tire
life, and excessive
temperature can lead to
sudden tire failure. The
grade C corresponds to a
level of performance which
all passenger car tires must
meet under the Federal
Motor Safety Standard
No. 109. Grades B and A
represent higher levels of
performance on the
laboratory test wheel than
the minimum required by

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16406251) - 2023 - CRC - 3/28/22
Vehicle Care 399
law. Warning: The
temperature grade for this
tire is established for a tire
that is properly inflated and
not overloaded. Excessive
speed, underinflation,
or excessive loading, either
separately or in
combination, can cause
heat buildup and possible
tire failure.
Wheel Alignment and
Tire Balance
The tires and wheels were
aligned and balanced at the
factory to provide the longest
tire life and best overall
performance. Adjustments to
wheel alignment and tire
balancing are not necessary
on a regular basis. Consider an
alignment check if there is
unusual tire wear or the
vehicle is significantly pulling
to one side or the other. Some
slight pull to the left or right,
depending on the crown of theroad and/or other road
surface variations such as
troughs or ruts, is normal.
If the vehicle is vibrating when
driving on a smooth road, the
tires and wheels may need to
be rebalanced. See your
dealer for proper diagnosis.
Wheel Replacement
Replace any wheel that is
bent, cracked, or badly rusted
or corroded. If wheel nuts
keep coming loose, the wheel,
wheel bolts, and wheel nuts
should be replaced. If the
wheel leaks air, replace it.
Some aluminum wheels can be
repaired. See your dealer if
any of these conditions exist.
Your dealer will know the kind
of wheel that is needed.
Each new wheel should have
the same load-carrying
capacity, diameter, width,
offset, and be mounted the
same way as the one it
replaces.
Replace wheels, wheel bolts,
wheel nuts, or Tire Pressure
Monitor System (TPMS)
sensors with new GM original
equipment parts.
{Warning
Using the wrong
replacement wheels, wheel
bolts, or wheel nuts can be
dangerous. It could affect
the braking and handling of
the vehicle. Tires can lose air
and cause loss of control,
resulting in a crash. Always
use the correct wheel, wheel
bolts, and wheel nuts for
replacement.
{Warning
Replacing a wheel with a
used one is dangerous. How
it has been used or how far
it has been driven may be
unknown. It could fail
suddenly and cause a crash.

16406251) - 2023 - CRC - 3/28/22
400 Vehicle Care
Warning (Continued)
When replacing wheels, use
a new GM original
equipment wheel.
Caution
The wrong wheel can also
cause problems with bearing
life, brake cooling,
speedometer or odometer
calibration, headlamp aim,
bumper height, vehicle
ground clearance, and tire or
tire chain clearance to the
body and chassis.
Tire Chains
{Warning
If the vehicle has 235/
55R20h size tires, do not
use tire chains. There is not
enough clearance. Tire
chains used on a vehicle
without the proper amount(Continued)
Warning (Continued)
of clearance can cause
damage to the brakes,
suspension, or other vehicle
parts. The area damaged by
the tire chains could cause
loss of control and a crash.
Use another type of traction
device only if its
manufacturer recommends
it for the vehicle's tire size
combination and road
conditions. Follow that
manufacturer's instructions.
To avoid vehicle damage,
drive slow and readjust or
remove the traction device if
it contacts the vehicle. Do
not spin the wheels. If
traction devices are used,
install them on the front
tires.
Caution
If the vehicle is equipped
with a tire size other than
235/55R20, use tire chains
only where legal and only
when necessary. Use low
profile chains that add no
more than 12 mm thickness
to the tire tread and inner
sidewall. Use chains that are
the proper size for the tires.
Install them on the tires of
the front axle. Do not use
chains on the tires of the
rear axle. Tighten them as
tightly as possible with the
ends securely fastened.
Drive slowly and follow the
chain manufacturer's
instructions. If the chains
contact the vehicle, stop and
retighten them. If the
contact continues, slow
down until it stops. Driving
too fast or spinning the
wheels with chains on will
damage the vehicle.

Vehicle Care 401
If a Tire Goes Flat
It is unusual for a tire to blow
out while driving, especially if
the tires are maintained
properly. See Tires0376. If air
goes out of a tire, it is much
more likely to leak out slowly.
But if there is ever a blowout,
here are a few tips about what
to expect and what to do:
If a front tire fails, the flat tire
creates a drag that pulls the
vehicle toward that side. Take
your foot off the accelerator
pedal and grip the steering
wheel firmly. Steer to maintain
lane position, and then gently
brake to a stop, well off the
road, if possible.
A rear blowout, particularly on
a curve, acts much like a skid
and may require the same
correction as used in a skid.
Stop pressing the accelerator
pedal and steer to straighten
the vehicle. It may be very
bumpy and noisy. Gently brake
to a stop, well off the road,
if possible.{Warning
Driving on a flat tire will
cause permanent damage to
the tire. Re-inflating a tire
after it has been driven on
while severely underinflated
or flat may cause a blowout
and a serious crash. Never
attempt to re-inflate a tire
that has been driven on
while severely underinflated
or flat. Have your dealer or
an authorized tire service
center repair or replace the
flat tire as soon as possible.
{Warning
Lifting a vehicle and getting
under it to do maintenance
or repairs is dangerous
without the appropriate
safety equipment and
training. If a jack is provided
with the vehicle, it is
designed only for changing a
(Continued)
Warning (Continued)
flat tire. If it is used for
anything else, you or others
could be badly injured or
killed if the vehicle slips off
the jack. If a jack is provided
with the vehicle, only use it
for changing a flat tire.
If a tire goes flat, avoid further
tire and wheel damage by
driving slowly to a level place,
well off the road, if possible.
Turn on the hazard warning
flashers. See Hazard Warning
Flashers 0155.
If your vehicle is loaded at or
near maximum cargo capacity,
it may be difficult to fit the jack
under the vehicle due to the
environment (shoulder slope,
road debris, etc.). Removal of
some weight may improve the
ability to fit the jack under the
vehicle at the correct jacking
location.
