Brake Wear
Your vehicle has front disc brakes and rear drum
brakes.
Disc brake pads have built-in wear indicators that
make a high-pitched warning sound when the
brake pads are worn and new pads are needed.
The sound can come and go or be heard all
the time your vehicle is moving, except when you
are pushing on the brake pedal rmly.
{CAUTION:
The brake wear warning sound means that
soon the brakes will not work well. That
could lead to an accident. When you hear
the brake wear warning sound, have your
vehicle serviced.
Notice:Continuing to drive with worn-out
brake pads could result in costly brake repair.Some driving conditions or climates can cause a
brake squeal when the brakes are rst applied
or lightly applied. This does not mean something
is wrong with the brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated,
inspect brake pads for wear and evenly tighten
wheel nuts in the proper sequence to GM torque
specications.
Rear drum brakes do not have wear indicators,
but if you ever hear a rear brake rubbing
noise, have the rear brake linings inspected
immediately. Also, the rear brake drums should be
removed and inspected each time the tires are
removed for rotation or changing. When you have
the front brake pads replaced, have the rear
brakes inspected, too.
Brake linings should always be replaced as
complete axle sets.
SeeBrake System Inspection on page 393.

Tires
Your new vehicle comes with high-quality tires
made by a leading tire manufacturer. If you ever
have questions about your tire warranty and where
to obtain service, see your GM Warranty booklet
for details. For additional information refer to
the tire manufacturer’s booklet included with your
vehicle.
{CAUTION:
Poorly maintained and improperly used
tires are dangerous.
Overloading your vehicle’s tires can
cause overheating as a result of too
much friction. You could have an
air-out and a serious accident. See
Loading Your Vehicle on page 253.
CAUTION: (Continued)
CAUTION: (Continued)

Underinated tires pose the same
danger as overloaded tires. The
resulting accident could cause serious
injury. Check all tires frequently to
maintain the recommended pressure.
Tire pressure should be checked when
your vehicle’s tires are cold. See
Inflation - Tire Pressure on page 329.
Overinated tires are more likely to be
cut, punctured, or broken by a sudden
impact — such as when you hit a
pothole. Keep tires at the
recommended pressure.
Worn, old tires can cause accidents. If
the tire’s tread is badly worn, or if
your vehicle’s tires have been
damaged, replace them.
322

(E) Uniform Tire Quality Grading (UTQG):Tire
manufacturers are required to grade tires
based on three performance factors: treadwear,
traction and temperature resistance. For more
information seeUniform Tire Quality Grading on
page 338.
(F) Maximum Cold Ination Load
Limit:Maximum load that can be carried and the
maximum pressure needed to support that
load. For information on recommended tire
pressure seeInation - Tire Pressure on page 329
andLoading Your Vehicle on page 253.
(A) Temporary Use Only:The compact spare
tire or temporary use tire has a tread life of
approximately 3,000 miles (5 000 km) and should
not be driven at speeds over 65 mph (105 km/h).
The compact spare tire is for emergency use when
a regular road tire has lost air and gone at.
SeeCompact Spare Tire on page 354andIf a
Tire Goes Flat on page 342.
Compact Spare Tire Example
324

Passenger (P-Metric) Tire:A tire used on
passenger cars and some light duty trucks and
multipurpose vehicles.
Recommended Ination Pressure:Vehicle
manufacturer’s recommended tire ination
pressure as shown on the tire placard. See
Ination - Tire Pressure on page 329andLoading
Your Vehicle on page 253.
Radial Ply Tire:A pneumatic tire in which the
ply cords that extend to the beads are laid
at 90 degrees to the centerline of the tread.
Rim:A metal support for a tire and upon which
the tire beads are seated.
Sidewall:The portion of a tire between the tread
and the bead.
Speed Rating:An alphanumeric code assigned
to a tire indicating the maximum speed at
which a tire can operate.
Traction:The friction between the tire and the
road surface. The amount of grip provided.
Tread:The portion of a tire that comes into
contact with the road.Treadwear Indicators:Narrow bands, sometimes
called wear bars, that show across the tread of a
tire when only 1/16 inch (1.6 mm) of tread remains.
SeeWhen It Is Time for New Tires on page 335.
UTQGS (Uniform Tire Quality Grading
Standards):A tire information system that
provides consumers with ratings for a tire’s
traction, temperature, and treadwear. Ratings are
determined by tire manufacturers using
government testing procedures. The ratings are
molded into the sidewall of the tire. SeeUniform
Tire Quality Grading on page 338.
Vehicle Capacity Weight:The number of
designated seating positions multiplied by 150 lbs
(68 kg) plus the rated cargo load. SeeLoading
Your Vehicle on page 253.
Vehicle Maximum Load on the Tire:Load on an
individual tire due to curb weight, accessory
weight, occupant weight, and cargo weight.
Vehicle Placard:A label permanently attached to
a vehicle showing the vehicle’s capacity weight
and the original equipment tire size and
recommended ination pressure. See “Tire and
Loading Information Label” underLoading
Your Vehicle on page 253.
328

Ination - Tire Pressure
Tires need the correct amount of air pressure to
operate effectively.
Notice:Do not let anyone tell you that
under-ination or over-ination is all right. It is
not. If your tires do not have enough air
(under-ination), you can get the following:
Too much exing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air (over-ination),
you can get the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road hazardsA Tire and Loading Information label is attached to
the vehicle’s center pillar (B-pillar). This label
shows your vehicle’s original equipment tires and
the correct ination pressures for your tires
when they are cold. The recommended cold tire
ination pressure, shown on the label, is the
minimum amount of air pressure needed to
support your vehicle’s maximum load carrying
capacity.
For additional information regarding how much
weight your vehicle can carry, and an example of
the Tire and Loading Information label, see
Loading Your Vehicle on page 253. How you load
your vehicle affects vehicle handling and ride
comfort. Never load your vehicle with more weight
than it was designed to carry.
When to Check
Check your tires once a month or more. Do not
forget to check the compact spare tire, it should be
at 60 psi (420 kPa). For additional information
regarding the compact spare tire, seeCompact
Spare Tire on page 354.
329

How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are
properly inated simply by looking at them. Radial
tires may look properly inated even when they
are under-inated. Check the tire’s ination
pressure when the tires are cold. Cold means your
vehicle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gage rmly onto the valve to
get a pressure measurement. If the cold tire
ination pressure matches the recommended
pressure on the Tire and Loading Information
label, no further adjustment is necessary. If the
ination pressure is low, add air until you reach the
recommended amount.
If you overll the tire, release air by pushing on
the metal stem in the center of the tire valve.
Re-check the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Pressure Monitor System
Your vehicle has a Tire Pressure Monitor System
(TPMS). This feature is designed to alert you
when the system detects a large change in the
pressure of one tire. The system cannot alert you
before you drive that a tire is low or at. You
must begin driving before the system works
properly. The TPMS works with the brake control
system and is designed to detect differences
in the tire rotation speeds that are caused
by changes in tire pressure. The TPMS does not
replace normal tire maintenance, seeTires on
page 322,Tire Inspection and Rotation on
page 333andWhen It Is Time for New Tires on
page 335.
330

This light, on the
instrument panel cluster,
comes on when the
tire pressure monitoring
system detects a
low-tire condition.
This light also comes on for a few seconds and
then go off when you turn the ignition to ON. This
indicates that the TPMS is functioning properly.
If the low-tire pressure warning light comes
on while driving your vehicle, the system may
have detected a low-tire condition. You need to
stop as soon as possible and check your tires
for damage. If a tire is at, seeIf a Tire Goes Flat
on page 342andChanging a Flat Tire on
page 343. Also check the tire pressure in all four
tires, and set them to the specied level shown
on the Tire and Loading Information label.SeeInation - Tire Pressure on page 329and
Loading Your Vehicle on page 253for additional
information.
Note:The tire pressure monitoring system on your
vehicle warns you when one of the tires is
signicantly under-inated and when some
combinations of the tires are signicantly
under-inated. However, there are other
combinations of signicantly under-inated tires for
which the tire pressure monitoring system might not
give a warning. These other combinations are
relatively common, accounting for approximately
half the instances in which vehicles have
signicantly under-inated tires. For example, the
system might not warn you when both tires on the
same side or on the same axle of your vehicle are
signicantly under-inated. It is particularly
important, therefore, to check the tire pressure in all
of the tires regularly and maintain proper pressure.
In order for the tire pressure monitoring system to
work properly you need to reset (initialize) the
tire pressure monitoring system. Any time
you check and/or adjust a tire’s pressure, repair or
replace a tire or wheel, or rotate the tires the
tire pressure monitor system needs to be reset.
331

The low-tire pressure warning light may not come
on even if the tire ination pressure is low, or it
could come on when the tire ination pressure is
set correctly under the following circumstances:
A compact spare tire, snow tires, or tire chains
are installed on your vehicle.
The tires are over-inated, or the tire ination
pressure suddenly drops due to a tire bursting
or other causes.
The vehicle is driven on a slippery road
surface such as rough or frozen roads.
The vehicle speed is less than
19 mph (30 km/h), and the driving duration is
less than ve minutes.
The tires are made by a different manufacturer
or differ in tread pattern than the original
equipment tires.
Rapid acceleration/deceleration or multiple
consecutive sharp turns.
Towing a trailer.
The vehicle is loaded over the limit or not
balanced properly.
The initialization (reset) procedure was not
performed correctly after replacing or
rotating tires or wheels.
The outside temperature is below 32°F (0°C)
or above 104°F (40°C).
Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your
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 335
andWheel Replacement on page 340for
more information.
The purpose of regular rotation is to achieve
more uniform wear for all tires on the vehicle.
The rst rotation is the most important. See
Part A: Scheduled Maintenance Services on
page 376for scheduled rotation intervals.
333

When rotating your 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 your tire
rotation.
After the tires have been rotated, adjust the front
and rear ination pressures to the amounts
shown on the Tire and Loading Information label.Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications on page 369.
{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
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
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. SeeChanging a Flat Tire on page 343.
Vehicles equipped with a tire pressure monitoring
system will need to reset (initialize) the system
after each tire rotation. SeeTire Pressure Monitor
System on page 330.
