2008 PONTIAC GRAND PRIX brake

If a Tire Goes Flat (GXP)
GXP models have no spare tire, no tire changing
equipment, and no place for storing a spare or at tire.
If a tire goes at, avoid further tire and wheel damage
by driving slowly to a level place and stopping.
Then do this:
1. Turn on the hazard warning ashers. SeeHazard
Warning Flashers on page 3-6.
2. Park your vehicle. Set the parking brake rmly and
put the shift lever in PARK (P). SeeShifting Into
PARK (P) on page 2-34for additional information.
3. Turn off the engine.
4. Inspect the at tire.
If the tire has been separated from the wheel or has
damaged sidewalls or large tears that allow rapid air
loss, call a tire repair facility. SeeRoadside Assistance
Program on page 7-6.
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. The kit uses
a liquid tire sealant to seal small punctures in the tread
area of the tire. The at tire is then inated to at least
30 psi (207 kPa) and driven to evenly distribute the tire
sealant. 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 operatingpressure 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. SeeInflation - Tire Pressure
on page 5-69.
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/retailer for inspection and repair. See
Tire Sealant and Compressor Kit (GXP) on page 5-86
for additional information.
Tire Sealant and Compressor
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.

{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).
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 even more certain the vehicle will not
move, you should 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 your vehicle has a at tire, use the following
example as a guide to assist you in the placement of
wheel blocks.
The following information tells you how to use the jack
and change a tire.
5-97

Once you have removed the wheel cover, use the
following procedure to remove the at tire and install the
spare tire.
1. It is recommended that you do a safety check
before preceding. SeeChanging a Flat Tire on
page 5-96for more information.
2. Set the park brake
rmly.
3. Turn the wheel wrench
once on each wheel
nut to loosen them. Do
not remove them yet.
4. Find the jacking location located on the underside
of the rocker trim using the diagram. For jacking at
the vehicle’s front location, put the jack lift head (C)
about 6 inches (15 cm) from the rear edge of the
front wheel opening (B). Line up the jack with the
arrow (A) as shown.

{CAUTION:
Incorrect or improperly tightened wheel nuts
can cause the wheel to come loose and even
come off. This could lead to a crash. If you
have to replace them, be sure to get new
original equipment wheel nuts. Stop
somewhere as soon as you can and have the
nuts tightened with a torque wrench to the
proper torque specication. SeeCapacities and
Specifications on page 5-128for wheel nut
torque specication.
Notice:Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specication. SeeCapacities and
Specifications on page 5-128for the wheel nut
torque specication.12. Tighten the wheel nuts
rmly in a crisscross
sequence as shown.
Notice:Wheel covers will not t on your vehicle’s
compact spare. If you try to put a wheel cover
on the compact spare, the cover or the spare could
be damaged.
