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. Your vehicle
was designed and tested with
top-quality brake parts. When you
replace parts of the braking
system — for example, when the
brake linings wear down and
you need new ones put in — be
sure you get new approved
replacement parts. If you do not, the
brakes might not work properly.
For example, if someone puts
in brake linings that are wrong for
your vehicle, the balance between
the front and rear brakes can
change — for the worse. The
braking performance you have come
to expect can change in many
other ways if someone puts in the
wrong replacement brake parts.
Battery
Your 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
behind a trim panel on the
driver’s side.
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 9-80for tips
on working around a battery
without getting hurt.
Infrequent Usage: If you drive your
vehicle infrequently, remove the
black, negative (−) cable from
the battery. This will help keep the
battery from running down.
Extended Storage: For extended
storage of your vehicle, remove the
black, negative (−) cable from
the battery or use a battery trickle
charger. This will help maintain
the charge of the battery over an
extended period of time.

Tire Sealant and
Compressor Kit
(V8 Engine)
This vehicle has a tire sealant and
compressor kit in place of a jack or
spare tire. It is located in a foam
container in the trunk. The tire
sealant and compressor kit can be
used to repair a at tire by sealing
small punctures in the tread of the
tire. It can also be used to inate an
underinated tire. The vehicle must
be driven for ve miles (8 kilometers)
after the tire is sealed and inated to
the recommended pressure to
ensure the sealant is distributed
evenly. For detailed instructions see
“Using the Tire Sealant and
Compressor Kit to Temporarily
Repair a Punctured Tire” later in this
section.The kit includes:
A. On/Off Switch
B. Air Compressor Accessory Plug
C. Air Compressor
D. Sealant Canister
E. Sealant/Air Hose
F. Air-only Hose
G. Pressure Gage
Tire Sealant
The sealant can temporarily seal a
small puncture up to 6 mm in
the tread area of the tire. The
sealant cannot seal sidewall
damage, large punctures, or a wheel
that has unseated from the wheel.
Read and follow the safe handling
instructions on the label adhered to
the sealant canister.
Check the tire sealant expiration
date on the sealant canister.
The sealant canister should be
replaced before its expiration date.
There is only enough sealant to
seal one tire. After usage, the
sealant canister and sealant/air hose
assembly must be replaced.
Replacement sealant canisters are
available from a dealer/retailer.
See “Removal and Installation of
Sealant Canister” later in this
section.

11. Unplug the air compressor
accessory plug (B) from the
accessory power outlet in
the vehicle.
12. Turn the sealant/air hose (E)
counterclockwise to remove.
13. Replace the tire valve
stem cap.
14. Stow the sealant/air hose (E)
and air compressor accessory
plug (B) in their original
locations.
15. If the at tire was able to be
inated to the recommended
ination pressure, remove
the maximum speed label from
the sealant canister and
place it in a highly visible
location.The maximum speed label
reminds you to drive cautiously
and not to exceed 55 mph
(90 km/h) until you have
the damaged tire inspected and
repaired.
{CAUTION
Storing the tire sealant and
compressor kit 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 the tire sealant
and compressor kit in its
original location.
16. Return the equipment to its
original storage location in
the trunk.
17. Immediately drive the vehicle
5 miles (8 km) to distribute the
sealant evenly in the tire.18. Stop at a safe location and
check the tire pressure, refer
to Steps 1 through 9 under
“Using the Tire Sealant
and Compressor Kit without
Sealant to Inate an
Underinated Tire” later in this
section.
If the tire pressure has fallen
more then 10 psi (68 kPa),
below the recommended
ination pressure, stop driving
the vehicle. The tire is too
severely damaged and the tire
sealant and compressor
cannot seal the tire. See
Roadside Assistance Program
on page 12-6if you need
assistance.
If the tire pressure has not
dropped more than 10 psi
(68 kPa) from the recommended
ination pressure, inate the tire
back up to the recommended
ination pressure.
Vehicle Service and Care 9-67
2008 - Pontiac G8 Owner Manual

{CAUTION
Idling the engine in a closed-in
place or with the climate
control system off can cause
deadly carbon monoxide (CO).
SeeEngine Exhaust on
page 8-12.
5. Start the vehicle. The vehicle
must be running while using
the air compressor.
{CAUTION
Overination could cause the
tire to rupture, and you or
others could be injured. Be
sure to read the inator
instructions, and inate the tire
to its recommended pressure.
Do not exceed 36 psi (248 kPa).6. Push the On/Off switch (G) to the
I (on) position.
Check the pressure gage (F). If
there is not a pressure reading
while the compressor is running,
check for leaks at the connection
between the hose and the tire
valve stem.
7. Inate the tire up to the
recommended ination pressure
using the air pressure gage (F)
on the top of the unit. See
Inflation - Tire Pressure on
page 9-46.
The pressure gage (F) reads
slightly high while the compressor
is on. Turn the compressor off to
get an accurate reading. The
compressor may be turned on
and off until the correct pressure
is reached.
8. Push the On/Off switch (G) to the
O (off) position.
Be careful while handling the tire
sealant and compressor kit as
they could be hot after usage.9. Unplug the air compressor
accessory plug (A) from the
accessory power outlet in the
vehicle and stow it in its original
location.
10. Disconnect the air-only hose (E)
from the tire valve stem and
stow it back in its original
location.
11. Replace the tire valve stem cap.
{CAUTION
Storing the tire sealant and
compressor kit 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 the tire sealant
and compressor kit in its
original location.
12. Place the equipment in the
original location in the trunk
of your vehicle.
