be heard all the time when the
vehicle is moving, except when
applying the brake pedal firmly.
{Warning
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Caution
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 first 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 torque
specifications. See
Capacities and
Specifications 0310.
Brake pads should be replaced as
complete sets.
Brake Pedal Travel
See your dealer if the brake pedal
does not return to normal height,
or if there is a rapid increase in
pedal travel. This could be a sign
that brake service may be required.
Replacing Brake System Parts
Always replace brake system parts
with new, approved replacement
parts. If this is not done, the brakes
may not work properly. The braking
performance expected can change
in many other ways if the wrong
replacement brake parts are
installed or if parts are improperly
installed.
Brake Fluid
The brake/clutch master cylinder
reservoir is filled with GM approved
DOT 3 brake fluid as indicated on
the reservoir cap. See Engine
Compartment Overview 0226 for
the location of the reservoir.
Checking Brake Fluid
Place the vehicle in P (Park) or
Neutral with the parking brake
applied if equipped with a manual
transmission. On a level surface,
the brake fluid level should be
between the minimum and
maximum marks on the brake fluid
reservoir.

unusual wear continues after the
rotation, check the wheel
alignment.
SeeWhen It Is Time for New
Tires 0266 andWheel
Replacement 0271.
Use this rotation pattern when
rotating the tires.
Do not include the compact
spare tire in the tire rotation.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after the tires have been rotated.
See
Tire Pressure 0260 and
Vehicle Load Limits 0181.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation 0262.
Check that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” underCapacities
and Specifications 0310.
{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 a crash. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
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
Factors such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tires.

head into the proper location
before raising the vehicle.
7. Turn the wheel wrench clockwise to raise the vehicle.
Raise the vehicle far enough
off the ground so there is
enough room for the compact
spare tire to fit underneath the
wheel well.
8. Turn the wheel nuts counterclockwise to
remove them.
9. Remove the flat tire.

10. Remove any rust or dirt fromthe wheel bolts, mounting
surfaces, and spare wheel.
11. Place the compact spare tire on the wheel-mounting surface.
{Warning
Never use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel
could fall off, causing a crash.
12. Reinstall the wheel nuts. Tighten each nut by hand until
the wheel is held against
the hub.
13. Lower the vehicle by turning the wheel wrench
counterclockwise. Lower the
jack completely.
{Warning
Wheel nuts that are improperly or
incorrectly tightened can cause
the wheels to become loose or
come off. The wheel nuts should
be tightened with a torque wrench
to the proper torque specification
after replacing. Follow the torque

using accessory locking wheel
nuts. SeeCapacities and
Specifications 0310 for original
equipment wheel nut torque
specifications.
Caution
Improperly tightened wheel nuts
can lead to brake pulsation and
rotor damage. To avoid expensive
brake repairs, evenly tighten the
wheel nuts in the proper
sequence and to the proper
torque specification. See
Capacities and Specifications
0 310 for the wheel nut torque
specification.14. Tighten the wheel nuts firmly in a crisscross sequence, as
shown.
Caution
Wheel covers will not fit on the
vehicle's compact spare. If you try
to put a wheel cover on the
compact spare, the cover or the
spare could be damaged.
Storing a Flat or Spare Tire
and Tools
{Warning
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.
Storing the Flat Tire and Tools 1. Return the jack and tools to their original storage location.
2. Replace the trim cover.
3. Place the flat tire, lying flat, in the rear storage compartment.
If the vehicle is a sedan the flat
tire should be against the back
of the rear seats.
If the vehicle is a hatchback
the flat tire should be against
the back of the trunk.
