wheel torque PONTIAC G8 2009 Owners Manual

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 torque
specications inCapacities and
Specifications on page 10-2.
Brake linings should always be
replaced as complete axle sets.Brake Pedal Travel
See your dealer/retailer 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 might
be required.
Brake Adjustment
Every time he brakes are applied,
with or without the vehicle moving,
the brakes adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle
is complex. Its many parts have
to be of top quality and work
well together if the vehicle is
to have really good braking.The vehicle was designed and
tested with top-quality brake parts.
When parts of the braking system
are replaced — for example,
when the brake linings wear
down and new ones are
installed — be sure to get new
approved replacement parts. If this
is not done, the brakes might
not work properly. For example,
if someone puts in brake linings that
are wrong for the vehicle, the
balance between the front and rear
brakes can change — for the
worse. The braking performance
expected can change in many other
ways if the wrong replacement
brake parts are installed.

Any time you notice unusual
wear, rotate the 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 9-59andWheel
Replacement on page 9-64.
When rotating the vehicle’s tires,
always use the correct rotation
pattern shown here.The compact spare tire, if the
vehicle has one, is not included
in the tire rotation.
After the tires have been rotated,
adjust the front and rear ination
pressures as shown on the Tire
and Loading Information label.
SeeInflation - Tire Pressure on
page 9-49andLoading the
Vehicle on page 8-30.
Reset the Tire Pressure Monitor
System. SeeTire Pressure
Monitor Operation on page 9-54.
Make certain that all wheel
nuts are properly tightened.
See “Wheel Nut Torque” under
Capacities and Specifications on
page 10-2.{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 9-75.

13. Lower the vehicle by turning the
jack handle counterclockwise.
Lower the jack completely.
14. Tighten the wheel nuts rmly in
a crisscross sequence, as
shown.{CAUTION
Incorrect or improperly tightened
wheel nuts can cause the wheel to
come loose and even come off.
This could lead to a crash. If you
have to replace them, be sure to
get new original equipment wheel
nuts. Stop somewhere as soon
as you can and have the nuts
tightened with a torque wrench to
the proper torque specication.
SeeCapacities and Specifications
on page 10-2for wheel nut torque
specication.Notice: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 specication.
SeeCapacities and Specifications
on page 10-2for the wheel nut
torque specication.
