386 Vehicle Care
Put the valve caps back on
the valve stems to keep out
dirt and moisture. Use only
valve caps designed for the
vehicle by GM. TPMS
sensors could be damaged
and would not be covered
by the vehicle warranty.
Tire Pressure for
High-Speed Operation
{Warning
Driving at high speeds,
160 km/h (100 mph) or
higher, puts additional strain
on tires. Sustained
high-speed driving causes
excessive heat buildup and
can cause sudden tire
failure. This could cause a
crash, and you or others(Continued)
Warning (Continued)
could be killed. Some
high-speed rated tires
require inflation pressure
adjustment for high-speed
operation. When speed
limits and road conditions
allow the vehicle to be
driven at high speeds, make
sure the tires are rated for
high-speed operation, are in
excellent condition, and are
set to the correct cold tire
inflation pressure for the
vehicle load. Vehicles with tire sizes listed
in the High Speed Operation
Inflation Pressures table
require inflation pressure
adjustment when driving the
vehicle at speeds of 160 km/h
(100 mph) or higher. Set the
cold tire inflation pressure to
the corresponding value in the
table for the tire size on the
vehicle.

inflation pressure when
high-speed driving has ended.
See Vehicle Load Limits 0247
and Tire Pressure 0384.
Tire Pressure Monitor
System
The Tire Pressure Monitor
System (TPMS) uses radio and
sensor technology to check
tire pressure levels. The TPMS
sensors monitor the air
pressure in your tires and
transmit tire pressure
readings to a receiver located
in the vehicle.
Each tire, including the spare
(if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the
vehicle manufacturer on the
vehicle placard or tire inflation
pressure label. (If your vehicle
has tires of a different size
than the size indicated on the
vehicle placard or tire inflation
pressure label, you should
determine the proper tire
inflation pressure for those
tires.)
As an added safety feature,
your vehicle has been
equipped with a tire pressure
monitoring system (TPMS)
that illuminates a low tire
pressure telltale when one or
more of your tires is
significantly under-inflated.
Accordingly, when the low tire
pressure telltale illuminates,
you should stop and check
your tires as soon as possible,
and inflate them to the proper
pressure. Driving on a
significantly under-inflated tire
causes the tire to overheat
and can lead to tire failure.
Under-inflation also reduces
energy efficiency and tire
tread life, and may affect the
vehicle's handling and
stopping ability.
Please note that the TPMS is
not a substitute for proper tire
maintenance, and it is the
driver's responsibility to
maintain correct tire pressure,
even if under-inflation has not

16406251) - 2023 - CRC - 3/28/22
388 Vehicle Care
reached the level to trigger
illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been
equipped with a TPMS
malfunction indicator to
indicate when the system is
not operating properly. The
TPMS malfunction indicator is
combined with the low tire
pressure telltale. When the
system detects a malfunction,
the telltale will flash for
approximately one minute and
then remain continuously
illuminated. This sequence will
continue upon subsequent
vehicle start-ups as long as
the malfunction exists.
When the malfunction
indicator is illuminated, the
system may not be able to
detect or signal low tire
pressure as intended. TPMS
malfunctions may occur for a
variety of reasons, including
the installation of replacement
or alternate tires or wheels on
the vehicle that prevent theTPMS from functioning
properly. Always check the
TPMS malfunction telltale
after replacing one or more
tires or wheels on your vehicle
to ensure that the
replacement or alternate tires
and wheels allow the TPMS to
continue to function properly.

Operation
0388.
See Radio Frequency
Statement 0452.
Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System
(TPMS). The TPMS is designed
to warn the driver when a low
tire pressure condition exists.
TPMS sensors are mounted
onto each tire and wheel
assembly, excluding the spare
tire and wheel assembly. The
TPMS sensors monitor the air
pressure in the tires and transmit the tire pressure
readings to a receiver located
in the vehicle.
When a low tire pressure
condition is detected, the
TPMS illuminates the low tire
pressure warning light on the
instrument cluster. If the
warning light comes on, stop
as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire
and Loading Information label.
See Vehicle Load Limits
0247.
A message to check the
pressure in a specific tire
displays in the Driver
Information Center (DIC). The
low tire pressure warning light
and the DIC warning message
come on at each ignition cycle
until the tires are inflated to
the correct inflation pressure.

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16406251) - 2023 - CRC - 3/28/22
Vehicle Care 389
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

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.
