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.
9-52 Vehicle Care
TPMS Reset
The TPMS sensors and transmitters
have unique identification codes.
Anytime you replace a TPMS sensor
or transmitter the identification codes
need to be registered and the TPMS
needs to be reset (initialized). When
the system is initialized, the current
air pressure in the tires is set as the
tire pressure benchmark. The tire
pressure warning system determines
decreased air pressure by comparing
tire pressure to the benchmark
pressure stored in the TPMS.
Do not reset the TPMS without first
correcting the cause of a low-tire
condition.
To reset the system:
1. Park the vehicle at a safe placeand apply the parking brake.
Turn the engine off.
2. Turn the ignition to ACC/ACCESSORY or
LOCK/OFF. 3. Adjust the tire pressure of all the
installed tires to the specified
cold tire inflation pressure level
indicated on the Tire and Loading
Information label attached to
the vehicle.
4. Turn the ignition to ON/RUN with the engine off.
5. Press and hold the tire pressure warning reset switch until the tire
pressure warning light flashes
slowly on/off three times.
Wait for a few minutes with the
ignition in ON/RUN, and then turn
the ignition to ACC/ACCESSORY
or LOCK/OFF. If the low-tire pressure warning
light does not flash three times
while you press and hold the
reset button, the reset has failed.
Repeat the reset process. If the
reset cannot be performed, see
your dealer/retailer for service.
If you press the tire pressure reset
switch while the vehicle is moving,
the reset is not performed. If you
press the tire pressure reset switch
accidentally and initialization is
performed, adjust the tire pressure to
the specified level and perform the
reset procedure again.
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. See When It Is
Time for New Tires on page 9-56
for more information.
9-54 Vehicle Care
Tire Rotation
Tires should be rotated every
5,000 to 8,000 miles (8 000 to
13 000 km). SeeScheduled
Maintenance on page 10-3.
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.
See When It Is Time for New
Tires on page 9-56 andWheel
Replacement on page 9-60 for
more information. When rotating the vehicle’s tires,
always use the correct rotation
pattern shown here.
Tires should only be moved from
front to rear and rear to front on
the same side of the vehicle.
Do not include the compact
spare tire in the tire rotation.
After the tires have been
rotated, adjust the front and
rear inflation pressures to the
amounts shown on the Tire
and Loading Information label.See
Tire Pressure on page 9-49
and Vehicle Load Limits on
page 8-12.
{CAUTION
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 9-62.
Make certain that all wheel
nuts are properly tightened.
See “Wheel Nut Torque” under
Capacities and Speci cations
on page 11-2.
Vehicle Care 9-55
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.
Vehicle Care 9-57
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.
