2008 PONTIAC G8 Owners Manual

Using the Tire Sealant and
Compressor Kit to
Temporarily Seal and Inate a
Punctured Tire
Follow these directions closely for
correct sealant usage.
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 GageDo a safety check before
proceeding. SeeIf a Tire Goes Flat
on page 9-62.
Inspect the damaged tire.
The sealant cannot seal sidewall
damage, large punctures, or a
tire that has unseated from
the wheel. SeeRoadside Assistance
Program on page 12-6.
Do not remove any objects that
have penetrated the tire.
1. Place the tire sealant and
compressor kit on the ground and
unwrap the sealant/air hose (E)
from the side of the compressor.
2. Remove the air compressor
accessory plug (B) from the unit.
Do not plug the plug in yet.
3. Turn the tire valve stem cap
counterclockwise to remove.
4. Attach the sealant/air hose (E)
onto the tire valve stem. Turn
it clockwise until tight.5. Make sure the sealant and
compressor kit on/off switch (A) is
in the O (off) position.
Plug the air compressor
accessory plug (B) into an
accessory power outlet in the
vehicle. SeeAccessory Power
Outlet(s) on page 4-9for
more information.
Do not slam door or close
window on the compressor
accessory plug cord.
{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.
6. Start the vehicle. The vehicle
must be running while using
the air compressor.

2008 - Pontiac G8 Owner Manual

{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).
7. Push the On/Off switch (A) to the
I (on) position.
The kit will begin to inject sealant
into the tire. Sealant could leak
from the puncture hole until
the vehicle is driven and the hole
has sealed.
8. Check the air pressure gage (G).
If there is not a pressure reading
while the compressor is
running, check for leaks at the
connection between the tire valve
stem and the sealant/air
hose (E).9. Inate the tire to the
recommended ination
pressure, found on the Tire
and Loading Information label.
SeeInflation - Tire Pressure
on page 9-46.
The pressure gage (G) will
initially read high while the
compressor injects the sealant
into the tire. Once the sealant
injection is complete, the
pressure will quickly drop. It will
start to rise again as the tire
inates with air.
10. Turn the compressor off by
pushing the On/Off button (A)
to the I (off) position.
The pressure gage (G) 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.Notice:If the recommended
pressure cannot be reached after
approximately 15 minutes, the
vehicle should not be driven. The
tire is too severely damaged
and the tire sealant and
compressor kit cannot inate the
tire. Remove the air compressor
accessory plug from the
accessory power outlet and
unscrew the sealant/air hose from
the tire valve or tire pressure
monitoring sensor valve.
SeeRoadside Assistance
Program on page 12-6.
The tire is not sealed and will
continue to leak air until the
vehicle is driven and the sealant
is distributed in the tire.
Steps 11 through 19 must be
done right after Step 10.
Be careful while handling the tire
sealant and compressor kit as
they could be hot after usage.

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.

19. Wipe off any sealant from the
wheel, tire or vehicle.
20. Dispose of the used sealant
canister at a local dealer/retailer
or in accordance with local
state codes and practices.
After using the sealant canister,
replace it with a new canister
available from your
dealer/retailer.
This is a temporary repair. Take
the vehicle to your dealer/retailer
to have the tire repaired or
replaced as soon as possible.Using the Air Compressor
without Sealant to Inate an
Underinated Tire
To use the air compressor to inate
a tire with air only and not sealant:
A. Air Compressor Accessory Plug
B. Air Compressor
C. Sealant Canister
D. Sealant/Air Hose
E. Air-only Hose
F. Pressure Gage
G. On/Off SwitchDo a safety check before
proceeding. SeeIf a Tire Goes Flat
on page 9-62.
To use the air compressor to inate
a tire with air only and not sealant:
1. Lift the lever and pull the air-only
hose (E) from the bottom of
the kit.
2. Remove the tire valve stem cap
from the at tire by turning it
counterclockwise.
3. Push the air-only hose (E) onto
the tire valve stem and push
the lever down to secure in place.
4. Plug the air compressor
accessory plug (A) into an
accessory power outlet in the
vehicle. SeeAccessory Power

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

Changing a Flat Tire
(V6 Engine)
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 the shift lever in
PARK (P).
(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, use the
following example as a guide to
assist you in the placement of wheel
blocks.
