2009 PONTIAC G8 change wheel

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.

The TPMS operates on a radio
frequency and complies with
RSS-210 of Industry and Science
Canada. Operation is subject to the
following two conditions:
1. This device may not cause
interference.
2. This device must accept any
interference received, including
interference that may cause
undesired operation of the device.
Changes or modications to this
system by other than an authorized
service facility could void
authorization to use this equipment.Tire Pressure Monitor
Operation
The Tire Pressure Monitor System
(TPMS) is designed to warn 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. The
TPMS sensors monitor the air
pressure in the vehicle’s tires and
transmit the tire pressure readings to
a receiver located in the vehicle.
When a low tire pressure condition
is detected, the TPMS turns on the
7
low tire pressure warning light.
At the same time a message to
check the pressure in a specic tire
appears on the Driver Information
Center (DIC) display. The low tire
pressure warning light and the DIC
warning message come on at each
ignition cycle until the tires are
inated to the correct ination
pressure. Using the DIC, tire
pressure levels can be viewed bythe driver. For additional information
and details about the DIC operation
and displays seeDIC Operation and
Displays on page 4-22andDIC
Warnings and Messages on
page 4-26.
The low tire pressure warning light
may come on in cool weather
when the vehicle is rst 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 inated
to the proper pressure.
A Tire and Loading Information label
shows the size of the vehicle’s
original equipment tires and the
correct ination pressure for the
vehicle’s tires when they are cold.
SeeLoading the Vehicle on
page 8-30, for an example of the Tire
and Loading Information label and its
location on the vehicle. Also see
Inflation - Tire Pressure on
page 9-49.
9-54 Vehicle Service and Care

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.

Tire Changing
If a Tire Goes Flat
It is unusual for a tire to blowout
while you are driving, especially if
you maintain your tires properly. See
Tires on page 9-42. If air goes out of
a tire, It is much more likely to leak
out slowly. But if you should ever
have a blowout, here are a few tips
about what to expect and what to do:
If a front tire fails, the at tire will
create a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the
steering wheel rmly. Steer to
maintain lane position, and then
gently brake to a stop well out of the
traffic lane.A rear blowout, particularly on a
curve, acts much like a skid
and may require the same correction
you would use in a skid. In any
rear blowout, remove your foot from
the accelerator pedal. Get the
vehicle under control by steering the
way you want the vehicle to go. It
may be very bumpy and noisy,
but you can still steer. Gently brake
to a stop, well off the road if
possible.
If a tire goes at, and your vehicle
has a compact spare tire, see
Changing a Flat Tire on page 9-75.
This information shows you how
to use the vehicle’s tire changing
equipment and how to change a at
tire safely.
{CAUTION
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the appropriate
safety equipment and training. If a
jack is provided with the vehicle, it
is designed only for changing a
at tire. If it is used for anything
else, you or others could be badly
injured or killed if the vehicle slips
off the jack. If a jack is provided
with the vehicle, only use it for
changing a at tire.
9-66 Vehicle Service and Care

Changing a Flat Tire
If a tire goes at, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the
hazard warning ashers.
{CAUTION
Changing a tire can be dangerous.
The vehicle can slip off the jack
and roll over or fall on you or other
people. You and they could be
badly injured or even killed. Find a
level place to change your tire.
To help prevent the vehicle from
moving:
1. Set the parking brake rmly.
2. Put an automatic
transmission shift lever in
P (Park), or shift a manual
transmission to 1 (First) or
R (Reverse).
(Continued)
CAUTION (Continued)
3. Turn off the engine and do
not restart while the vehicle
is raised.
4. Do not allow passengers to
remain in the vehicle.
To be certain the vehicle will not
move, put blocks at the front and
rear of the tire farthest away from
the one being changed. That
would be the tire on the other
side, at the opposite end of the
vehicle.When you have a at tire, place the
wheel block at the tire diagonally
across from the at tire.

{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 9-75.10. Remove any rust or dirt from
the wheel bolts, mounting
surfaces and spare wheel.
11. Place the compact spare tire on
the wheel-mounting surface.
{CAUTION
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 with the
rounded end of the nuts toward
the wheel. Tighten each nut as
much as possible using the
wheel wrench until the wheel is
held rmly against the hub.
Use your free hand to prevent
the wheel from turning while
you are tightening.
