Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS warns 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.
When a low tire pressure condition
is detected, the low tire pressure
warning light, located on the
instrument panel cluster, comes on.This light also comes on for a
few seconds and then goes off when
you turn the ignition to ON/RUN.
This indicates the TPMS is
functioning properly. If the low-tire
pressure warning light comes on
while driving the vehicle, the system
may have detected a low-tire
condition. You need to stop as soon
as possible and check the tires.
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 could 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 the vehicle, shows
the size of the vehicle’s original
equipment tires and the correct
inflation pressure for the tires when
they are cold. See
Vehicle Load
Limits on page 8-12, for an example
of the Tire and Loading Information
label and its location on your vehicle.
Also see Tire Pressure on
page 9-49.
The vehicle’s TPMS can warn you
about a low tire pressure condition
but it does not replace normal tire
maintenance. See Tire Inspection
on page 9-54, Tire Rotation on
page 9-55 andTires on page 9-43.

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 1/16 inch (1.6 mm)
or less of tread remaining.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, even if they are not being used.
This is also true for the spare tire,
if the vehicle has one. 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 the vehicle. If you
need replacement tires, GM strongly
recommends that you get tires that
are the same size, brand, load range,
speed rating, and construction type
(radial and bias-belted tires) as the
vehicle’s original tires. This way, the
vehicle will continue to have tires
that are designed to give the same
performance and vehicle safety,
during normal use, as the original
tires. See
Tire Sidewall Labeling on
page 9-44 for additional information.
9-56 Vehicle Care

GM recommends replacing tires in
sets of four. This is because uniform
tread depth on all tires will help keep
the 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 the vehicle. SeeTire
Inspection on page 9-54 andTire
Rotation on page 9-55 .
{CAUTION
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 may not handle
properly, and you could have
a crash. Using tires of different
sizes, brands, or types may
also cause damage to your
(Continued)
CAUTION (Continued)
vehicle. Be sure to use the
correct size, brand, and type
of tires on all wheels. It is
all right to drive with your
compact spare temporarily,
as it was developed for use
on your vehicle. See Compact
Spare Tire on page 9-68.
{CAUTION
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.
Vehicles that have a tire pressure
monitoring system could give an
inaccurate low-pressure warning
if tires not recommended for the
vehicle are installed. Tires that do
not match the original equipment
tires could give a low-pressure
warning that is higher or lower than
the proper warning level you would
get with original equipment tires.
See Tire Pressure Monitor System
on page 9-50.
The vehicle’s original equipment
tires are listed on the Tire and
Loading Information Label. See
Vehicle Load Limits on page 8-12 ,
for more information about the Tire
and Loading Information label and
its location on the vehicle.

5. Loosen all the wheel nuts.Do not remove them yet.
6. Position the jack and raise the jack lift head to fit over the car
flange between the two notches.
{CAUTION
Getting under a vehicle when it
is jacked up is dangerous. If the
vehicle slips off the jack you could
be badly injured or killed. Never
get under a vehicle when it is
supported only by a jack.
{CAUTION
Raising your vehicle with the jack
improperly positioned can damage
the vehicle and even make the
vehicle fall. To help avoid personal
injury and vehicle damage, be
sure to fit the jack lift head into the
proper location before raising the
vehicle. 7. Turn the jack handle clockwise.
Raise the vehicle far enough off
the ground so there is enough
room for the compact spare tire
to fit underneath the wheel well.

Storing the Compact
Spare Tire
{CAUTION
Storing a jack, a tire, or other
equipment in the passenger
compartment of the vehicle could
cause injury. In a sudden stop or
collision, loose equipment could
strike someone. Store all these
in the proper place.
A. Compact Spare Tire (Valve Stem Pointed Down)
B. Jack C. Cargo Area Floor
D. Tire/Wheel Retainer Nut
E. Jack Handle
F. Wheel Wrench
1. Place the jack handle (E) and
wheel wrench (F) back in their
original location in the passenger
side of the cargo area.
2. Place the jack (B) back in its original location on the driver
side of the cargo area and close
the latch over the jack (B).
3. Place the compact spare tire (A), valve stem pointed down, back
in its original location in the
center of the cargo area.
4. Turn the tire/wheel retainer nut (D) clockwise to secure it
on the compact spare tire (A).
5. Close the cargo area floor (C).
Compact Spare Tire
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 8-12 for 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.
