PONTIAC GRAND PRIX 2007 Owners Manual

Tire Chains
{CAUTION:
If your vehicle has P225/55R17, P255/45R18
or P225/50R18 size tires, do not use tire
chains, there is not enough clearance.
Tire chains used on a vehicle without the
proper amount of clearance can cause
damage to the brakes, suspension or other
vehicle parts. The area damaged by the tire
chains could cause you to lose control of
your vehicle and you or others may be
injured in a crash.
Use another type of traction device
only if its manufacturer recommends
it for use on your vehicle and tire size
combination and road conditions. Follow
that manufacturer’s instructions.
CAUTION: (Continued)
CAUTION: (Continued)
To help avoid damage to your vehicle,
drive slowly, readjust or remove the
device if it is contacting your vehicle, and
do not spin your wheels.
If you do nd traction devices that will t,
install them on the front tires.
Notice:If your vehicle does not have
P225/55R17, P255/45R18 or P225/50R18 size
tires, use tire chains only where legal and only
when you must. Use only SAE Class S-type
chains that are the proper size for your
tires. Install them on the front tires and tighten
them as tightly as possible with the ends
securely fastened. Drive slowly and follow the
chain manufacturer’s instructions. If you
can hear the chains contacting your vehicle,
stop and retighten them. If the contact
continues, slow down until it stops. Driving
too fast or spinning the wheels with chains on
will damage your vehicle.

If a Tire Goes Flat
It is unusual for a tire to blowout while you are
driving, especially if you maintain your tires
properly. SeeTires on page 400. If air goes out of
a tire, it is much more likely to leak out slowly.
But if you should ever have a blowout, here are a
few tips about what to expect and what to do:
If a front tire fails, the at tire will create a drag that
pulls the vehicle toward that side. Take your
foot off the accelerator pedal and grip the steering
wheel rmly. Steer to maintain lane position,
and then gently brake to a stop well out of the
traffic lane.
A rear blowout, particularly on a curve, acts much
like a skid and may require the same correction
you’d use in a skid. In any rear blowout, remove
your foot from the accelerator pedal. Get the
vehicle under control by steering the way you want
the vehicle to go. It may be very bumpy and
noisy, but you can still steer. Gently brake to a
stop, well off the road if possible.If a tire goes at, and your vehicle has a spare
tire, seeChanging a Flat Tire on page 435.
This information shows you how to use your
vehicle’s tire changing equipment and how
to change a at tire safely.
{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous
without the appropriate safety equipment
and training. The jack provided with your
vehicle is designed only for changing a
at tire. If it is used for anything else, you
or others could be badly injured or killed
if the vehicle slips off the jack. Use the
jack provided with your vehicle only for
changing a at tire.
422

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. See
Hazard Warning Flashers on page 134.
2. Park your vehicle. Set the parking brake rmly
and put the shift lever in PARK (P). See
Shifting Into Park (P) on page 116for
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. See
Roadside Assistance Program on page 498.
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 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 408.
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 498.
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 424for additional information.
423

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
424

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 using the tire
inator kit, it is recommended to take your vehicle
to an authorized GM dealer within 100 miles
(161 kilometers) of driving to have the tire
inspected and repaired. If the sealant isn’t
removed from the tire within a 100 miles
(161 kilometers) of driving, it is more likely
that the tire and tire pressure monitoring sensor
may get damaged and have to be replaced.Accessing the Tire Inator Kit
To access the tire inator kit, do the following:
1. Open the trunk. SeeTrunk on page 96
for 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.
425

4. Remove the inator kit by pulling it straight
out of the foam container.
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.
426

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.
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.
SeeAccessory Power Outlet(s) on page 156
for more information.
427

{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 119.
6. Start the vehicle. SeeStarting the Engine on
page 107for 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.
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.
428

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. See
Roadside Assistance Program on page 498.10. 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.
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.
429

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.
