2006 PONTIAC GRAND PRIX Owners Manual

The tire pressure is checked after driving for a maximum
of ve miles (8.0 km) to see if the slow leak has been
stopped. If the tire pressure is 19 psi (131 kPa) or more,
inate the tire up to the standard operating pressure as
shown on the tire and loading information label. This label
is attached to the vehicle’s center-pillar below the driver’s
door latch. SeeInation - Tire Pressure on page 5-67.
Notice:If the tire pressure has dropped below
19 psi (131 kPa), the vehicle should not be driven.
Damage to the tire may be severe and the sealant
will not be effective. Contact Roadside Assistance,
seeRoadside Assistance Program on page 7-6.
You should have the damaged tire repaired as soon as
possible. The tire sealant is a temporary repair only.
If the tire has been lled with tire sealant, take the tire to
a GM dealer for inspection and repair. SeeTire
Inator Kit (GXP) on page 5-79for additional
information.
Tire Inator Kit (GXP)
Your vehicle may have a tire inator kit. The kit uses a
liquid tire sealant and air at the same time to seal small
punctures in the tread area of the tire. Be sure to read
and follow all the tire inator kit instructions. The kit
includes the following:A. Air Compressor
B. Tire Sealant Canister
C. Air Compressor
Accessory Plug
D. On/Off SwitchE. Air Pressure Gage
F. Air Compressor
Inator Hose
G. Sealant Filling Hose
If the at tire is due to a slow leak caused by a nail or
other similar road hazard, the tire inator kit may
be used to temporarily repair the damaged tire.
After temporarily repairing a tire with the tire inator kit,
take your vehicle to an authorized GM dealer to
have the tire inspected and repaired.

Accessing the Tire Inator Kit
To access the tire inator kit, do the following:
1. Open the trunk. SeeTrunk on page 2-13for more
information.
2. Locate the tire inator kit by lifting up the carpet.
3. Remove the inator
kit cover by turning
the center nut
counterclockwise.
4. Remove the inator kit by pulling it straight out of
the foam container.
5-80

Tire Sealant
The kit contains a liquid sealant that when injected into a
at tire, may temporarily repair nail holes or cuts in the
tread area of the tire. The tire sealant cannot repair tire
damage caused while driving on a at tire or a tire that
has had a “blow out” or a tire that has punctures in the
sidewall areas. The tire sealant solution is to be used for
a single tire and can only be used once.
Check the tire sealant expiration date on the sealant
canister. The sealant may not be as effective beyond the
expiration date. If needed, see your GM dealer for a
replacement canister.
After temporarily repairing a tire using the tire sealant,
take your vehicle to an authorized GM dealer to have the
tire inspected and repaired.
Using the Tire Inator Kit
To use the tire inator kit, do the following:
1. Place the inator kit on the ground and unwrap the
sealant lling hose from the compressor.
2. Remove the air compressor accessory plug from
the unit. To do this, pull the top portion of the
wrapped cord out rst, then the bottom, then unsnap
the plug. Do not insert the plug into an accessory
outlet yet.
3. Remove the valve stem cap from the at tire by
turning it counterclockwise.
If an object, such as a nail, has penetrated the tire,
do not remove it.
5-81

4. Attach the sealant lling hose (A) onto the tire valve
stem. Turn it clockwise until it is tight.
Make sure the inator kit on/off switch (B) is in the
O (off) position.
5. Plug the air compressor accessory plug (C) into an
accessory power outlet in the vehicle. See
Accessory Power Outlet(s) on page 3-24for more
information.
{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 2-33.
6. Start the vehicle. SeeStarting the Engine on
page 2-23for more information. The vehicle must be
running while using the air compressor.
{CAUTION:
Inating something too much can make it
explode, 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. Move the inator kit switch to the I (on) position.
The inator kit will force sealant and air into the
tire. Sealant may leak from the puncture hole until
the vehicle is driven and the hole has sealed.
5-82

8. Make sure there is a proper connection between
the tire valve stem and the sealant lling hose by
looking at the air pressure gage. If there is not
a pressure reading while the compressor is running,
the connection between the inator kit and the
tire is bad.
Check the attachment between the sealant lling
hose and the tire valve stem.
9. Inate the tire up to the recommended ination
pressure, found on the Tire and Loading Information
label located on the vehicle’s center pillar (B-pillar)
below the vehicle’s door latch, using the air pressure
gage on the top of the unit as a guide.
The pressure gage reading is slightly high while the
compressor is on. Turn the compressor off to get
an accurate pressure reading.
Notice:If the recommended pressure cannot be
reached after 15 minutes, the vehicle should not be
driven farther. Damage to the tire is severe and
the sealant will not be effective. Remove the
air compressor plug from the accessory power
outlet and unscrew the inating hose from the tire
valve. SeeRoadside Assistance Program on
page 7-6.10. Move the inator kit switch to the O (off) position
once the correct tire pressure is obtained.
11. Turn off the engine.
12. Unplug the air compressor accessory plug from the
accessory power outlet in the vehicle.
13. Disconnect the sealant lling hose from the tire
valve stem, by turning it counterclockwise, and
replace the tire valve stem cap.
Be careful when handling the tire inator
components as they may be hot after usage.
14. Wrap the sealant lling hose around the air
compressor channel to stow it in its original location.
5-83

15. Stow the air compressor accessory plug back in the
air compressor. To do this, wrap the air compressor
accessory plug, snap in the plug, and then push
in the bottom and then the top of the wrapped
air compressor accessory plug.
16. If the at tire was able
to inate to the
recommended ination
pressure, remove the
maximum speed label
from the sealant
canister.
Place it in a highly visible location such as the
inside of the upper left corner of the windshield or
to the face of the radio/clock.
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 inator 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 inator kit in the proper place.
17. Return the equipment to the proper storage location
in the trunk of your vehicle.
5-84

18. Immediately drive the vehicle 5 miles (8 km) to
distribute the sealant evenly in the tire. Stop at a
safe location and check the tire pressure. Refer to
Steps 1 through 8 under “Using the Air Compressor
without Sealant” next in this section. If the tire
pressure has fallen more than 10 psi (68 kPa) below
the recommended ination pressure, stop driving
the vehicle. The tire is too damaged for the sealant
to work. SeeRoadside Assistance Program on
page 7-6.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended ination
pressure, you can inate the tire back up to
the recommended ination pressure.
19. Dispose of the sealant canister at a local GM dealer
or in accordance with your local state codes and
practices.
After using the sealant canister, replace it with a
new canister from a GM dealer.
20. After temporarily repairing a tire with the emergency
at tire repair kit, take your vehicle to an authorized
GM dealer to have the tire inspected and repaired.Using the Air Compressor
without Sealant
To use the air compressor by itself to inate a tire, do
the following:
1. Remove the air compressor accessory plug from
the air compressor.
2. Unlock the air compressor hose from the sealant
canister by pulling up on the lever.
