Vehicle Care 10-53
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 fuel 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 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
the TPMS 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.

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 vehicle's 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 panel cluster.The low tire pressure warning light
comes on at each ignition cycle until
the tires are inflated to the correct
inflation pressure.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as you start to drive. This
may be an early indicator that the
air pressure in the tire(s) are getting
low and need to be inflated to the
proper pressure.
A Tire and Loading Information
label, attached to your vehicle,
shows the size of your vehicle's
original equipment tires and the
correct inflation pressure for your
vehicle's tires when they are cold.
See
Vehicle Load Limits
on
page 9‑22, for an example of the
Tire and Loading Information label
and its location on your vehicle.
Also see Tire Pressure
on
page 10‑50.
Your vehicle's TPMS system can
warn you about a low tire pressure
condition but it does not replace
normal tire maintenance. See Tire
Inspection
on page 10‑57, Tire
Rotationon page 10‑57and Tireson
page 10‑43.
Notice: Liquid tire sealants could
damage the Tire Pressure Monitor
System (TPMS) sensors. Sensor
damage caused by using a tire
sealant is not covered by your
warranty. Do not use liquid tire
sealants.

TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. Any time you
replace one or more of the TPMS
sensors or rotate the vehicle's tires,
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/retailer for service.
The TPMS sensors can also be
matched to each tire/wheel position
by increasing or decreasing the
tire's air pressure. When increasing
the tire's pressure, do not exceed
the maximum inflation pressure
indicated on the tire's sidewall.To decrease the tire's air-pressure
use the pointed end of the valve
cap, a pencil-style air pressure
gage, or a key.
You have two minutes to match
each tire and wheel position. If it
takes longer than two minutes to
match any tire and wheel position,
the matching process stops and
you will need to start over.
The TPMS matching process is
outlined below:
1. Set the parking brake.
2. Turn the ignition switch to
ON/RUN with the engine off.
3. Press and hold the RKE transmitter's Lock and Unlock
buttons at the same time, for
about three seconds. The horn
will sound twice to indicate the
receiver is ready for the sensor
matching process to begin. 4. Start with the driver side front
tire. The driver side turn signal
lamp comes on.
5. Remove the valve cap from the tire's valve 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 the
tire/wheel position.
6. Proceed to the passenger side front tire. The passenger side
front turn signal lamp comes on.
Repeat the procedure in Step 5.
7. Proceed to the passenger side rear tire. The passenger side
rear turn signal lamp comes on.
Repeat the procedure in Step 5.

Do not include the compact
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. SeeTire Pressure
on
page 10‑50
and Vehicle Load
Limits
on page 9‑22.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation
on page 10‑54.
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. 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. See If a Tire Goes Flat
on page 10‑65.
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 inch) or
less of tread remaining.
ProCarManuals.com
Vehicle Care 10-59
The vehicle needs new 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.
The rubber in tires degrades 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.
With proper care and maintenance
tires typically wear out before they
degrade due to age. If you are
unsure about the need to replace
the tires as they get older, consult
the tire manufacturer for more
information.
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.
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. See
Tire
Sidewall Labeling
on page 10‑44
for additional information.

5. Remove the disk (A) from theretainer bolt. Turn the disk (A)
over and place it back on the
retainer bolt.
Return the disk back to its
original position after removing
the flat tire from the spare tire
compartment and before storing
the spare tire.
6. Place the wheel retainer bolt
onto the wheel stow rod and
tighten by turning it clockwise. The compact spare is for temporary
use only. Replace the compact
spare tire with a full-size tire as
soon as possible.
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
crash and you or others could be
injured. Use only one compact
spare tire at a time.
The compact spare tire was fully
inflated when the vehicle was new,
but it can lose air after a time.
Check the inflation pressure
regularly. See Vehicle Load Limits
on page 9‑22for the correct
inflation pressure.
Do not exceed 80 km/h (50 mph)
when driving with a spare tire. The spare tire is for temporary
emergency use only. Replace it with
a regular tire as soon as possible.
Notice:
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 temporary spare on
other vehicles.
Do not mix the temporary spare tire
or wheel with other wheels or tires.
They will not fit. Keep the spare tire
and its wheel together.
Notice: Tire chains will not fit the
compact spare. Using them can
damage the vehicle and can
damage the chains too. Do not
use tire chains on the compact
spare.
