sensors monitor the air pressure in
the tires and transmits 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. SeeVehicle Load
Limits on page 9‑10.
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) on page 5‑27.
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 on page 9‑10, for an example
of the Tire and Loading Information
label and its location. Also see Tire
Pressure on page 10‑41.
The TPMS can warn about a low
tire pressure condition but it does
not replace normal tire maintenance. See
Tire Inspection
on page 10‑48, Tire Rotation on
page 10‑48 andTires on
page 10‑34.
Notice: 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.
Factory-installed Tire Inflator Kits
use a GM approved liquid tire
sealant. Using non-approved tire
sealants could damage the TPMS
sensors. See Tire Sealant and
Compressor Kit on page 10‑57 for
information regarding the inflator kit
materials and instructions.

10-48 Vehicle Care
Tire Inspection
We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected
for signs of wear or damage at
least once a month.
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 every
12 000 km (7,500 mi). See
Maintenance Schedule on
page 11‑3.
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. SeeWhen It Is Time for New Tires on page 10‑54
and
Wheel Replacement on
page 10‑54.
Four-Tire Rotation Pattern
Use the four-tire rotation pattern
shown if the vehicle has a
compact spare tire. Do not
include the spare tire in the tire
rotation process.

Black plate (49,1)Cadillac XTS Owner Manual - 2013 - 1st - 4/13/12
Vehicle Care 10-49
Five-Tire Rotation Pattern
Use the five-tire rotation pattern
shown for professional vehicles
that have a full-size spare tire
and wheel assembly that
matches the original equipment
tires and wheels in size, type,
and brand.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after
the tires have been rotated. SeeTire Pressure on page 9‑10
and
Vehicle Load Limits on
page 9‑10.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on
page 10‑44.
Check that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” underCapacities
and Specifications on
page 12‑2.
{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
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
(Continued)
WARNING (CONTINUED)
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
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.

Black plate (50,1)Cadillac XTS Owner Manual - 2013 - 1st - 4/13/12
10-50 Vehicle Care
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. SeeTire
Inspection on page 10‑48 andTire
Rotation on page 10‑48.
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. GM recommends that
tires, including the spare if equipped, be replaced after six
years, regardless of tread wear. The
tire manufacturer date is the last
four digits of the DOT Tire
Identification Number (TIN) which is
molded into one side of the tire
sidewall. The first two digits
represent the week (01–52) and the
last two digits, the year. For
example, the third week of the year
2010 would have a four-digit DOT
date of 0310.Vehicle Storage
Tires age when stored normally
mounted on a parked vehicle. Park
a vehicle that will be stored for at
least a month in a cool, dry, clean
area away from direct sunlight to
slow aging. This area should be free
of grease, gasoline, or other
substances that can deteriorate
rubber.
Parking for an extended period can
cause flat spots on the tires that
may result in vibrations while
driving. When storing a vehicle for
at least a month, remove the tires or
raise the vehicle to reduce the
weight from the tires.
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

performance on the laboratory
test wheel than the minimum
required by 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
will not be necessary on a regular
basis. However, check the
alignment if there is unusual tire
wear or if the vehicle is pulling to
one side or the other. If the vehicle
vibrates when driving on a smoothroad, the tires and wheels might
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, causing
a crash. Always use the correct
wheel, wheel bolts, and wheel
nuts for replacement.
Notice: 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.
Professional vehicle wheels have a
unique offset and bolt hole diameter.
Professional vehicle wheels have
six wheel nuts. Non-professional
vehicle wheels have five wheel nuts.

10-60 Vehicle Care
1. Remove the tire sealant andcompressor kit from its storage
location. See Storing the Tire
Sealant and Compressor Kit on
page 10‑65.
2. Unwrap the sealant/air hose (6) and the power plug (8).
3. Place the kit on the ground. Make sure the tire valve stem is
positioned close to the ground
so the hose will reach it.
4. Remove the valve stem cap from the flat tire by turning it
counterclockwise.
5. Attach the sealant/air hose (6) onto the tire valve stem. Turn it
clockwise until it is tight. 6. Plug the power plug (8) into the
accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See Power Outlets on page 5‑6.
If the vehicle has an accessory
power outlet, do not use the
cigarette lighter.
If the vehicle only has a cigarette
lighter, use the cigarette lighter.
Do not pinch the power plug
cord in the door or window.
7. Start the vehicle. The vehicle must be running while using the
air compressor.
8. Press and turn the selector switch (1) counterclockwise to
the Sealant + Air position. 9. Press the on/off button (2) to
turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire.
The pressure gauge (3) will
initially show a high pressure
while the compressor pushes the
sealant into the tire. Once the
sealant is completely dispersed
into the tire, the pressure will
quickly drop and start to rise
again as the tire inflates with
air only.
10. Inflate the tire to the recommended inflation
pressure using the pressure
gauge (3). The recommended
inflation pressure can be found
on the Tire and Loading
Information label. See Tire
Pressure on page 10‑41.

Black plate (61,1)Cadillac XTS Owner Manual - 2013 - 1st - 4/13/12
Vehicle Care 10-61
The pressure gauge (3) may
read higher than the actual tire
pressure while the compressor
is on. Turn the compressor off
to get an accurate pressure
reading. The compressor may
be turned on/off until the
correct pressure is reached.
Notice: If the recommended
pressure cannot be reached after
approximately 25 minutes, the
vehicle should not be driven
farther. The tire is too severely
damaged and the tire sealant and
compressor kit cannot inflate the
tire. Remove the power plug from
the accessory power outlet and
unscrew the inflating hose from
the tire valve. See Roadside
Service on page 13‑5. 11. Press the on/off button (2) to
turn the tire sealant and
compressor kit off.
The tire is not sealed and will
continue to leak air until the
vehicle is driven and the
sealant is distributed in the tire,
therefore, Steps 12–18 must be
done immediately after
Step 11.
Be careful while handling the
tire sealant and compressor kit
as it could be warm after
usage.
12. Unplug the power plug (8) from the accessory power outlet in
the vehicle. 13. Turn the sealant/air hose (6)
counterclockwise to remove it
from the tire valve stem.
14. Replace the tire valve stem cap.
15. Replace the sealant/air hose (6), and the power plug (8)
back in their original location.
16. If the flat tire was able to inflateto the recommended inflation
pressure, remove the
maximum speed label from the
sealant canister (5) and place it
in a highly visible location. Do
not exceed the speed on this
label until the damaged tire is
repaired or replaced.

10-62 Vehicle Care
17. Return the equipment to itsoriginal storage location in the
vehicle.
18. Immediately drive the vehicle 8 km (5 mi) to distribute the
sealant in the tire.
19. Stop at a safe location and check the tire pressure. Refer
to Steps 1–11 under “Using the
Tire Sealant and Compressor
Kit without Sealant to Inflate a
Tire (Not Punctured).”
If the tire pressure has fallen
more than 68 kPa (10 psi)
below the recommended
inflation pressure, stop driving
the vehicle. The tire is too
severely damaged and the tire
sealant cannot seal the tire.
See Roadside Service on
page 13‑5.
If the tire pressure has not
dropped more than 68 kPa
(10 psi) from the recommended
inflation pressure, inflate the
tire to the recommended
inflation pressure. 20. Wipe off any sealant from the
wheel, tire, and vehicle.
21. Dispose of the used sealant canister (5) and sealant/air
hose (6) assembly at a local
dealer or in accordance with
local state codes and practices.
22. Replace with a new canister assembly available from your
dealer.
23. After temporarily sealing the tire using the tire sealant and
compressor kit, take the
vehicle to an authorized dealer
within 161 km (100 mi) of
driving to have the tire repaired
or replaced.Using the Tire Sealant and
