2009 PONTIAC G8 Owners Manual

Do a safety check before
proceeding. SeeIf a Tire
Goes Flat on page 9-66.
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). See
Engine Exhaust on page 8-14.6. 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).
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.
Vehicle Service and Care 9-69

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. See
Inflation - Tire Pressure on
page 9-49.
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. See
Roadside 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.
9-70 Vehicle Service and Care

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 9-71

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 9-66.
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

5. Lift the sealant canister from the
compressor and replace with a
new sealant canister. Dispose of
the sealant canister at a local
dealer/retailer or in accordance
with local state codes and
practices. Replace it with a new
canister, available form your

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.
