Loading Your VehicleThe Tire-Loading Information/Certification label on
your vehicle, located in the glovebox, shows how much
weight it may properly carry. The Tire
-Loading
Information label tells you the proper size, and
recommended inflation pressures for the tires on your
vehicle. It also gives you important information about
the number of people that can be in your vehicle and the
total weight that you can carry. This weight is called the
Vehicle Capacity Weight, and includes the weight of all
occupants, cargo and all nonfactory
-installed options.

5-31
Compact Spare Tire
Although the compact spare tire was fully inflated
when your vehicle was new, it can lose air after a time.
Check the inflation pressure regularly. It should
be 60 psi (420 kPa).
After installing the compact spare on your vehicle, you
should stop as soon as possible and make sure your
spare tire is correctly inflated. The compact spare is
made to perform well at speeds up to 50 mph (80 km/h)
for distances up to 3,000 miles (5 000 km), so you can
finish your trip and have your full
-size tire repaired or
replaced where you want. Of course, it's best to replace
your spare with a full
-size tire as soon as you can. Your
spare will last longer and be in good shape in case you
need it again.
NOTICE:
When the compact spare is installed, don't take
your vehicle through an automatic car wash with
guide rails. The compact spare can get caught on
the rails. That can damage the tire and wheel,
and maybe other parts of your vehicle.
Don't use your compact spare on other vehicles.
And don't mix your compact spare tire or wheel with
other wheels or tires. They won't fit. Keep your spare
tire and its wheel together.
NOTICE:
Tire chains won't fit your compact spare. Using
them can damage your vehicle and can damage
the chains too. Don't use tire chains on your
compact spare.

6-51 High Performance Tire (Option)
If this vehicle has the optional 17-inch P215/50ZR17
size tires, they are ªhigh performanceº tires. High
performance tires are designed for very responsive
driving on wet or dry pavement, but they may not offer
the traction you would like on snow or ice covered
roads. You may also notice more road noise with high
performance tires and that they tend to wear faster. Also,
see ªTire Inspection and Rotationº later in this section or
in the Index.
For cold weather driving conditions, you may prefer to
get tires designed for snow or ice. See your Pontiac
dealer for details regarding winter tire availability and
proper tire selection. Also, see ªBuying New Tiresº later
in this section or in the Index.
Inflation -- Tire Pressure
The Tire-Loading Information label, which is in your
glove compartment, shows the correct inflation
pressures for your tires when they're cold. ªColdº
means your vehicle has been sitting for at least
three hours or driven no more than 1 mile (1.6 km).
NOTICE:
Don't let anyone tell you that underinflation or
overinflation is all right. It's not. If your tires
don't have enough air (underinflation), you can
get the following:

Too much flexing

Too much heat

Tire overloading

Bad wear

Bad handling

Bad fuel economy
If your tires have too much air (overinflation),
you can get the following:

Unusual wear

Bad handling

Rough ride

Needless damage from road hazards

6-53
When rotating your tires, always use the correct rotation
pattern shown here. If your vehicle has P215/502R17
tires, they must roll in a certain direction for the best
overall performance. The direction is shown by an arrow
on the sidewall. Because these tires are directional, they
should be rotated as shown here. These tires should only
be moved from front to rear and rear to front on the
same side of the vehicle.Don't include the compact spare tire in your
tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire
-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See ªWheel Nut Torqueº in
the Index.
CAUTION:
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after a time. The wheel could come off and cause
an accident. When you change a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this; but be
sure to use a scraper or wire brush later, if you
need to, to get all the rust or dirt off. See
ªChanging a Flat Tireº in the Index.

7-38 At Least Once a Month
Tire Inflation Check
Make sure tires are inflated to the correct pressures.
Don't forget to check your spare tire. See ªTiresº in the
Index for further details.
At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages are
working properly. Look for any other loose or damaged
safety belt system parts. If you see anything that might
keep a safety belt system from doing its job, have it
repaired. Have any torn or frayed safety belts replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace blade
inserts that appear worn or damaged or that streak or
miss areas of the windshield. Also see ªWiper Blades,
Cleaningº in the Index.Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. See ªRecommended Fluids and Lubricantsº
in the Index.
Fluid Level Check
Check the power steering pump and automatic or
manual transaxle fluid levels and add as needed.
See ªPower Steeringº and ªAutomatic Transaxleº
or ªManual Transaxleº in the Index. Check for leaks.
A fluid loss in these systems could indicate a problem.
Have the system inspected and repaired at once.
Manual Transaxle Check
It is not necessary to check the transaxle fluid level.
Check for leaks. A fluid leak is the only reason for fluid
loss. Have the system inspected and repaired if needed.
Automatic Transaxle Check
Check the transaxle fluid level; add if needed. See
ªAutomatic Transaxle Fluidº in the Index. A fluid loss
may indicate a problem. Check the system and repair
if needed.
