2009 PONTIAC G5 warning

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.
Battery
This vehicle has a maintenance free battery. When it is
time for a new battery, see your dealer/retailer for one
that has the replacement number shown on the original
battery’s label.
The battery is located in the trunk. Access to the battery
is not necessary to jump start the vehicle. SeeJump
Starting on page 5-34.Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
Vehicle Storage
{CAUTION:
Batteries have acid that can burn you and gas that
can explode. You can be badly hurt if you are not
careful. SeeJump Starting on page 5-34for tips
on working around a battery without getting hurt.
Infrequent Usage: If the vehicle is driven infrequently,
remove the black, negative (−) cable from the battery.
This helps keep the battery from running down.
Extended Storage: For extended storage of the vehicle,
remove the black, negative (−) cable from the battery or
use a battery trickle charger. This helps maintain the
charge of the battery over an extended period of time.

Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor System
(TPMS). The TPMS is designed to warn the driver when a
low tire pressure condition exists. If your vehicle has this
feature, TPMS sensors are mounted onto each tire and
wheel assembly, excluding the spare tire and wheel
assembly, if the vehicle has one. 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 low tire
pressure warning light
located on the instrument
panel cluster.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 by the
driver. For additional information and details about the
DIC operation and displays seeDIC Operation and
Displays on page 3-39andDIC Warnings and Messages
on page 3-42.
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
your vehicle’s original equipment tires and the correct
ination pressure for your vehicle’s tires when they are
cold. SeeLoading the Vehicle on page 4-22, for an
example of the Tire and Loading Information label and
its location on your vehicle. Also seeInflation - Tire
Pressure on page 5-55.
5-58

Your vehicle’s TPMS system can warn you about a low
tire pressure condition but it does not replace normal
tire maintenance. SeeTire Inspection and Rotation
on page 5-63andTires on page 5-48.
Notice:Using non-approved tire sealants could
damage the Tire Pressure Monitor System (TPMS)
sensors. TPMS sensor damage caused by using
an incorrect tire sealant is not covered by the
vehicle warranty. Always use the GM approved tire
sealant available through your dealer/retailer.
Factory-installed Tire Inator Kits use a GM approved
liquid tire sealant. Using non-approved tire sealants
could damage the TPMS sensors. SeeTire Sealant and
Compressor Kit on page 5-72for information regarding
the inator kit materials and instructions.TPMS Malfunction Light and Message
The TPMS will not function properly if one or more of the
TPMS sensors are missing or inoperable. When the
system detects a malfunction, the low tire warning light
ashes for about one minute and then stays on for the
remainder of the ignition cycle. A DIC warning message
is also displayed. The low tire warning light and DIC
warning message come on at each ignition cycle until the
problem is corrected. Some of the conditions that can
cause the malfunction light and DIC message to come
on are:
One of the road tires has been replaced with the
spare tire, if the vehicle has one. The spare tire does
not have a TPMS sensor. The TPMS malfunction
light and DIC message should go off once you
re-install the road tire containing the TPMS sensor.
The TPMS sensor matching process was started but
not completed or not completed successfully after
rotating the vehicle’s tires. The DIC message and
TPMS malfunction light should go off once the TPMS
sensor matching process is performed successfully.
See “TPMS Sensor Matching Process” later in this
section.
5-59

GM recommends replacing tires in sets of four.
This is because uniform tread depth on all tires
will help keep your 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 your vehicle.
SeeTire Inspection and Rotation on page 5-63for
information on proper tire rotation.
{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 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.
SeeCompact Spare Tire on page 5-93.
{CAUTION:
If you use bias-ply tires on the vehicle, the
wheel rim anges 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.
If you must replace your vehicle’s tires with those
that do not have a TPC Spec number, make sure
they are the same size, load range, speed rating,
and construction type (radial and bias-belted tires)
as your vehicle’s original tires.
Vehicles that have a tire pressure monitoring
system could give an inaccurate low-pressure
warning if non-TPC Spec rated tires are installed on
your vehicle. Non-TPC Spec rated tires may give a
low-pressure warning that is higher or lower than
the proper warning level you would get with TPC
Spec rated tires. SeeTire Pressure Monitor System
on page 5-56.
Your vehicle’s original equipment tires are listed
on the Tire and Loading Information Label.
SeeLoading the Vehicle on page 4-22, for more
information about the Tire and Loading Information
Label and its location on your vehicle.

If a Tire Goes Flat
It is unusual for a tire to blowout while you are driving,
especially if you maintain the tires properly. SeeTires on
page 5-48. 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, avoid further tire and wheel damage
by driving slowly to a level place and stopping.
1. Turn on the hazard warning ashers. SeeHazard
Warning Flashers on page 3-6.
2. Park the vehicle. Set the parking brake rmly and
put the shift lever in P (Park).3. Turn off the engine.
4. Inspect the at tire.
{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.
This vehicle may come with a jack and spare tire or a tire
sealant and compressor kit. To use the jack and spare
tire, seeChanging a Flat Tire on page 5-80. To use the
tire sealant and compressor kit, seeTire Sealant and
Compressor Kit on page 5-72.
5-71

Tire Sealant and Compressor Kit
Storage
The tire sealant and compressor kit is located in the
trunk.
1. Open the trunk. SeeTrunk on page 2-12.
2. Lift the trunk liner.
3. Remove the retainer that holds the tire sealant and
compressor kit.
4. Remove the kit from the foam container.
To store the tire sealant and compressor kit, reverse the
steps.
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. SeeHazard Warning Flashers
on page 3-6.
{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).
CAUTION: (Continued)
