alternate tires and wheels allow the
TPMS to continue to function
properly.
SeeTire Pressure Monitor
Operation 0266 for additional
information.
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
located 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 0177.
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. 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) 0128.
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 0177, for an example of the
Tire and Loading Information label
and its location. Also see Tire
Pressure 0263.
The TPMS can warn about a low
tire pressure condition but it does
not replace normal tire
maintenance. See Tire Inspection
0 268, Tire Rotation 0269 andTires
0 261.
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

Replace the tire if:
.The indicators at three or
more places around the tire
can be seen.
.There is cord or fabric
showing through the tire's
rubber.
.The tread or sidewall is
cracked, cut, or snagged
deep enough to show cord or
fabric.
.The tire has a bump, bulge,
or split.
.The tire has a puncture, cut,
or other damage that cannot
be repaired well because of
the size or location of the
damage.
Tire Rotation
Tires should be rotated at the
intervals specified in the
Maintenance Schedule. See
Maintenance Schedule0297. Tires are rotated to achieve a
uniform wear for all tires. The
first rotation is the most
important.
Anytime unusual wear is
noticed, rotate the tires as soon
as possible, check for proper tire
inflation pressure, and check for
damaged tires or wheels. If the
unusual wear continues after the
rotation, check the wheel
alignment. See
When It Is Time
for New Tires 0270 andWheel
Replacement 0273.
Use this rotation pattern when
rotating the tires.
Do not include the compact
spare tire in the tire rotation.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after
the tires have been rotated. See
Tire Pressure 0263 and Vehicle
Load Limits 0177.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation 0266.
Check that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” underCapacities
and Specifications 0305.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come

Buying New Tires
GM has developed and matched
specific tires for the vehicle. The
original equipment tires installed
were designed to meet General
Motors Tire Performance Criteria
Specification (TPC Spec)
system rating. When
replacement tires are needed,
GM strongly recommends
buying tires with the same TPC
Spec rating.
GM's exclusive TPC Spec
system considers over a dozen
critical specifications that impact
the overall performance of the
vehicle, including brake system
performance, ride and handling,
traction control, and tire
pressure monitoring
performance. GM's TPC Spec
number is molded onto the tire's
sidewall near the tire size. If the
tires have an all-season tread
design, the TPC Spec number
will be followed by MS for mud
and snow.GM recommends replacing worn
tires in complete sets of four.
Uniform tread depth on all tires
will help to maintain the
performance of the vehicle.
Braking and handling
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. See
Tire
Rotation 0269 for information
on proper tire rotation. However,
if it is necessary to replace only
one axle set of worn tires, place
the new tires on the rear axle.
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
tire's maximum speed capability
when using winter tires with a
lower speed rating.{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,
brands, or types may cause
loss of control of the vehicle,
resulting in a crash or other
vehicle damage. Use the
correct size, brand, and type
of tires on all wheels.

272 Vehicle Care
{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.
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.
Vehicles that have a tire
pressure monitoring system
could give an inaccurate
low-pressure warning if non-TPC
Spec rated tires are installed.
See Tire Pressure Monitor
System 0265. The Tire and Loading
Information label indicates the
original equipment tires on the
vehicle. See
Vehicle Load Limits
0 177 for the label location and
more information about the Tire
and Loading Information label.
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. 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 0271 and
Accessories and Modifications
0 228.
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

Cadillac XTS Owner Manual (GMNA-Localizing-MidEast-9369806) - 2016 -

274 Vehicle Care
Warning (Continued)
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.
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires
are maintained properly. SeeTires
0 261. If air goes out of a tire, it is
much more likely to leak out slowly.
But if there ever is 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 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 0156.
{Warning
Changing a tire can be
dangerous. The vehicle can slip
off the jack and roll over or fall

2. Replace the fastener rod withthe one provided in the foam.
3. Turn the wrench clockwise to tighten the fastener rod.
4. Replace the foam, jack and tools, and the tire.
5. Turn the retainer nut clockwise to secure the tire.
6. Place the floor cover on the wheel.
To store the compact spare tire, use
the shorter mounting bolt.
The compact spare is for temporary
use only. Replace the compact
spare tire with a full-size tire as
soon as you can.
Compact Spare Tire
{Warning
Driving with more than one
compact spare tire at a time could
result in loss of braking and
handling. This could lead to a (Continued)
Warning (Continued)
crash and you or others could be
injured. Use only one compact
spare tire at a time.
If this vehicle has a compact spare
tire, it was fully inflated when new;
however, it can lose air over time.
Check the inflation pressure
regularly. It should be 420 kPa
(60 psi).
Stop as soon as possible and check
that the spare tire is correctly
inflated after being installed on the
vehicle. The compact spare tire is
designed for temporary use only.
The vehicle will perform differently
with the spare tire installed and it is
recommended that the vehicle
speed be limited to 80 km/h
(50 mph). To conserve the tread of
the spare tire, have the standard tire
repaired or replaced as soon as
convenient and return the spare tire
to the storage area. When using a compact spare tire,
the ABS and Traction Control
systems may engage until the spare
tire is recognized by the vehicle,
especially on slippery roads. Adjust
driving to reduce possible
wheel slip.
Caution
When the compact spare is
installed, do not take the vehicle
through an automatic car wash
with guide rails. The compact
spare can get caught on the rails
which can damage the tire, wheel,
and other parts of the vehicle.
Do not use the compact spare on
other vehicles.
Do not mix the compact spare tire or
wheel with other wheels or tires.
They will not fit. Keep the spare tire
and its wheel together.

Service and Maintenance 297
At your dealer, you can be certain
that you will receive the highest
level of service available. Your
dealer has specially trained service
technicians, uses genuine
replacement parts, as well as,
up-to-date tools and equipment to
ensure fast and accurate
diagnostics.
The proper replacement parts,
fluids, and lubricants to use are
listed inRecommended Fluids and
Lubricants 0301 andMaintenance
Replacement Parts 0302. We
recommend the use of genuine
parts from your dealer.
Rotation of New Tires
Tire rotation is not recommended if
the vehicle has different size tires
on the front and rear wheels. If tire
rotation is recommended for the
vehicle, to maintain ride, handling,
and performance of the vehicle, it is
important that the first rotation
service for new tires be performed.
Tires should be rotated every
service. See Tire Rotation 0269.Maintenance
