ECU PONTIAC GRAND PRIX 2006 Service 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. 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. See
Tires on page 5-60. 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.

3. Pull the air compressor inator hose from the
sealant canister.
4. Push the air compressor inator hose onto the
tire valve stem and push the lever down to
secure in place.
5. Plug the air compressor accessory plug 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.
8. Make sure there is a proper connection between the
tire valve stem and the air compressor 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 air compressor
hose and the tire valve stem.
9. Inate the tire up to the recommended ination
pressure using the air pressure gage on the top
of the unit as a guide.
10. Turn off the air compressor by moving the switch to
the O (off) position.

10. Tighten the wheel nuts
rmly in a crisscross
sequence as shown.
Notice:Wheel covers will not t on your compact

spare, you could damage the cover or the spare.
Do not try to put the wheel cover on the compact spare
tire. It will not t. Store the wheel cover in the trunk
until the at tire is repaired or replaced.Storing a Flat or Spare Tire
and Tools
{CAUTION:
Storing a jack, a tire, 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
all these in the proper place.
After the compact spare tire is put on the vehicle, store
the at tire in the trunk. Use the following procedure
to secure it in the trunk. When storing a full-size tire, use
the extension and protector/guide, located in the foam
holder to help avoid wheel surface damage.
5-97

To store a full-size tire, do the following:
1. Install the tools in their original location in the trunk
area and secure.
2. Place the tire in the trunk with the valve stem facing
down, and the protector/guide placed through a
wheel bolt hole.
3. Remove the protector and attach the
retainer securely.
4. Place the protector/guide back in the foam holder
when putting the compact spare back in the trunk.
Store the cover as far forward as possible.
The compact spare tire is for temporary use only.
Replace the compact spare tire with a full-size tire as
soon as possible. SeeCompact Spare Tire on
page 5-99for more information. Use the following as a
