TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. Any time you
rotate your vehicle's tires or replace
one or more of the TPMS sensors,
the identification codes will need to
be matched to the new tire/wheel
position. The sensors are matched
to the tire/wheel positions in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear
tire using a TPMS diagnostic tool.
See your dealer for service.
The TPMS sensors can also be
matched to each tire/wheel position
by increasing or decreasing the
tire's air pressure. If increasing the
tire's air pressure, do not exceed
the maximum inflation pressure
indicated on the tire's sidewall.
To decrease air pressure out of a
tire you can use the pointed end of
the valve cap, a pencil-style air
pressure gauge, or a key.You have two minutes to match
the first tire/wheel position, and
five minutes overall to match all
four tire/wheel positions. If it takes
longer than two minutes to match
the first tire and wheel, or more than
five minutes to match all four tire
and wheel positions, the matching
process stops and you need to
start over.
The TPMS sensor matching process
is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to
ON/RUN with the engine off.
3. Press the Remote Keyless Entry (RKE) transmitter's lock and
unlock buttons at the same time
for approximately five seconds.
The horn sounds twice to signal
the receiver is in relearn mode
and the TIRE LEARNING
ACTIVE message displays on
the DIC screen. 4. Start with the driver side
front tire.
5. Remove the valve cap from the valve cap stem. Activate the
TPMS sensor by increasing
or decreasing the tire's air
pressure for five seconds,
or until a horn chirp sounds. The
horn chirp, which may take up to
30 seconds to sound, confirms
that the sensor identification
code has been matched to this
tire and wheel position.
6. Proceed to the passenger side front tire, and repeat the
procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat the
procedure in Step 5.

8. Proceed to the driver siderear tire, and repeat the
procedure in Step 5. The horn
sounds two times to indicate the
sensor identification code has
been matched to the driver side
rear tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARNING
ACTIVE message on the DIC
display screen goes off.
9. Turn the ignition switch to LOCK/OFF.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire
and Loading Information label.
11. Put the valve caps back on the valve stems.Tire Inspection
We recommend that you
regularly inspect your vehicle's
tires, including the spare tire,
if the vehicle has one, for signs
of wear or damage at least
once a month.
Always remove the tires if any
of the following statements
are true:
.You can see the indicators at
three or more places around
the tire.
.You can see 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 miles). See
Scheduled Maintenance on
page 11‑2.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that the vehicle
continues to perform most like it
did when the tires were new.
Any time you notice unusual
wear, rotate the tires as soon
as possible and check wheel
alignment. Also check for
damaged tires or wheels.

SeeWhen It Is Time for New
Tires on page 10‑63 andWheel
Replacement on page 10‑68.
When rotating the vehicle's tires,
always use the correct rotation
pattern shown here.
Do not include the spare tire in
the tire rotation. After the tires have been
rotated, adjust the front and rear
inflation pressures as shown on
the Tire and Loading Information
label. See
Tire Pressure on
page 10‑54 andVehicle Load
Limits on page 9‑23.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on
page 10‑58.
Make certain that all wheel nuts
are properly tightened. See
“Wheel Nut Torque” under
Capacities 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.
(Continued)
WARNING (Continued)
When changing a wheel, remove
any rust or dirt from places where
the wheel attaches to the vehicle.
In an emergency, use a cloth or a
paper towel to do this; but be sure
to use a scraper or wire brush
later, if needed, to get all the rust
or dirt off. SeeIf a Tire Goes Flat
on page 10‑69.
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
Various factors, such as
maintenance, temperatures, driving
speeds, vehicle loading, and road
conditions influence when you need
new tires.
One way to tell when it is time for
new tires is to check the treadwear
indicators, which appear when the
tires have only 1.6 mm (1/16 in) or
less of tread remaining. Some
commercial truck tires may not have
treadwear indicators. SeeTireInspection on page 10‑61
andTire
Rotation on page 10‑61 for
additional information.
The rubber in tires ages over time.
This is also true for the spare tire,
if the vehicle has one, even if it is
not being used. Multiple conditions
affect how fast this aging takes
place, including temperatures,
loading conditions, and inflation
pressure maintenance. Tires will
typically need to be replaced due to
wear before they may need to be
replaced due to age. Consult the tire
manufacturer for more information
on when tires should be replaced.
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 your vehicle. The
original equipment tires installed
on your vehicle, when it was new,
were designed to meet General
Motors Tire Performance Criteria
Specification (TPC Spec) system
rating. If you need replacement
tires, GM strongly recommends that
you get tires with the same TPC
Spec rating. This way, your vehicle
will continue to have tires that are
designed to give the same
performance and vehicle safety,
during normal use, as the original
tires.

Black plate (64,1)Cadillac Escalade EXT Owner Manual - 2011
10-64 Vehicle Care
GM's exclusive TPC Spec system
considers over a dozen critical
specifications that impact the
overall performance of your
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 an MS for mud and
snow. SeeTire Sidewall Labeling on
page 10‑50 for additional
information.
GM recommends replacing tires in
sets of four. This is because uniform
tread depth on all tires will help
keep your vehicle performing most
like it did when the tires were new.
Replacing less than a full set of tires
can affect the braking and handling
performance of your vehicle. See
Tire Inspection on page 10‑61 and
Tire Rotation on page 10‑61 for
information on proper tire rotation.{WARNING
Tires could explode during
improper service. You or others
could be injured or killed if you
attempt to mount or dismount a
tire. Only your dealer or an
authorized tire service center
should mount and dismount the
tires.
{WARNING
Mixing tires could cause you to
lose control while driving. If you
mix tires of different sizes,
brands, or types (radial and
bias-belted tires), the vehicle
might not handle properly, and
you could have a crash. Using
tires of different sizes, brands,
or types could also cause
(Continued)
WARNING (Continued)
damage to your vehicle. Be sure
to use the same size, brand, and
type of tires on all wheels.
Your vehicle may have a different
size spare than the road tires
(those originally installed on your
vehicle). When new, your vehicle
included a spare tire and wheel
assembly with a similar overall
diameter as your vehicle's road
tires and wheels, so it is all right
to drive on it. Because this spare
was developed for use on your
vehicle, it will not affect vehicle
handling.

Black plate (65,1)Cadillac Escalade EXT Owner Manual - 2011
Vehicle Care 10-65
{WARNING
If you use bias-ply tires on the
vehicle, the wheel rim flanges
could develop cracks after
many miles of driving. A tire
and/or wheel could fail
suddenly, causing a crash.
Use only radial-ply tires with
the wheels on the vehicle.
If you must replace your vehicle's
tires with those that do not have a
TPC Spec number, make sure they
are the same size, load range,
speed rating, and construction type
(radial and bias‐belted tires) as your
vehicle's original tires.
Vehicles that have a tire pressure
monitoring system may give an
inaccurate low‐pressure warning if
non‐TPC Spec-rated tires are
installed on your vehicle. Non‐TPC
Spec-rated tires may give a
low‐pressure warning that is higher
or lower than the proper warning level you would get with TPC
Spec-rated tires. See
Tire Pressure
Monitor System on page 10‑56.
Your vehicle's original equipment
tires are listed on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9‑23
for more information about the Tire
and Loading Information label and
its location on your vehicle.
Different Size Tires and
Wheels
If you add wheels or tires that are a
different size than your original
equipment wheels and tires, this
could affect the way your vehicle
performs, including its braking, ride
and handling characteristics,
stability, and resistance to rollover.
Additionally, if your vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction
control, and electronic stability
control, the performance of these
systems can be affected.
{WARNING
If you add different sized
wheels, your vehicle may not
provide an acceptable level of
performance and safety if tires not
recommended for those wheels
are selected. You may increase
the chance that you will crash and
suffer serious injury. Only use GM
specific wheel and tire systems
developed for your vehicle, and
have them properly installed by a
GM certified technician.
See Buying New Tires on
page 10‑63 andAccessories and
Modifications on page 10‑3 for
additional information.

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,
except some aluminum wheels,
which can sometimes be repaired.
See your dealer if any of these
conditions exist.
Your dealer will know the kind of
wheel you need.
Each new wheel should have the
same load-carrying capacity,
diameter, width, offset, and be
mounted the same way as the
one it replaces.
If you need to replace any of the
wheels, wheel bolts, wheel nuts,
or Tire Pressure Monitor System
(TPMS) sensors, replace them only
with new GM original equipment
parts. This way, you will be sure to
have the right wheel, wheel bolts,
wheel nuts, and TPMS sensors for
the vehicle.{WARNING
Using the wrong replacement
wheels, wheel bolts, or wheel
nuts on your vehicle can be
dangerous. It could affect the
braking and handling of your
vehicle, make your tires lose air
and make you lose control. You
could have a collision in which
you or others could be injured.
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.
See If a Tire Goes Flat on
page 10‑69 for more information.
Used Replacement Wheels
{WARNING
Putting a used wheel on the
vehicle is dangerous. You cannot
know how it has been used or
how far it has been driven.
It could fail suddenly and cause a
crash. If you have to replace a
wheel, use a new GM original
equipment wheel.

9. Position the center lift point ofthe jack under the center of the
spare tire.
10. Turn the wrench clockwise to raise the jack until it lifts the
end fitting.
11. Continue raising the jack until the spare tire stops moving
upward and is held firmly in
place. The secondary latch has
released and the spare tire is
balancing on the jack.
12. Lower the jack by turning the wheel wrench
counterclockwise. Keep lowering the jack until the
spare tire slides off the jack
or is hanging by the cable.
{WARNING
Someone standing too close
during the procedure could be
injured by the jack. If the spare
tire does not slide off the jack
completely, make sure no one is
behind you or on either side of
you as you pull the jack out from
under the spare.
13. Disconnect the jack handle from the jack and carefully
remove the jack. Use one hand
to push against the spare while
firmly pulling the jack out from
under the spare tire with the
other hand.
If the spare tire is hanging
from the cable, insert the hoist
end of extension, and wheel
wrench into the hoist shaft hole
in the bumper and turn the wheel wrench counterclockwise
to lower the spare the rest of
the way.
14. Turn the wheel wrench in the hoist shaft hole in the bumper
clockwise to raise the cable
back up if the cable is hanging
under the vehicle.
Have the hoist assembly inspected
as soon as you can. You will not be
able to store a spare or flat tire
using the hoist assembly until it has
been inspected and/or replaced.
To continue changing the flat tire,
see “Removing the Flat Tire and
Installing the Spare Tire” underTire
Changing on page 10‑71.
Full-Size Spare Tire
Your vehicle, when new, had a
fully-inflated spare tire. A spare tire
may lose air over time, so check its
inflation pressure regularly. See
Tire Pressure on page 10‑54 and
Vehicle Load Limits on page 9‑23
for information regarding proper tire
inflation and loading your vehicle.
