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 65 mph
(105 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. (When the
compact spare
is used on the rear axle, see Notice
below.) 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. When the compact
spare is on the rear axle, the optional
traction control system will cycle and limit acceleration
for about the first 15 seconds of driving after each
engine start.
NOTICE:
If the compact spare is used as a rear tire, do not
drive faster than
50 mph (SO km/h). Damage to
the rear axle may occur
if the compact spare is
driven faster than 50 mph
(80 kmh).

Hold the wiper blade assembly with one hand and
pull
the element gently with the other hand.
(Replacement blade elements have
three plastic caps
which retain two metal flexor strips.
Do not remove
these caps before the element
is installed.)
At
the heel end of the blade assembly, notched end
of blade element last, slide the blade element into the
blade claw sets.
The plastic retainer caps will be
forced off as the element is fully inserted. Make sure
that all the claw sets
are properly engaged in the
slots of the blade element.
Install wiper blade assembly on wiper arm.

type
and length, see “Capacities and Specifications” in
the Index.
Headlamp Aiming
Your vehicle has the headlamp system. These headlamps
have horizontal and vertical aim indicators. The
aim
has been pre-set at the factory and should need no
further adjustment.
If your vehicle is damaged in an accident and the
headlamp aim seems to be affected, see your Pontiac
dealer. Headlmps on damaged vehicles may require
recalibration of
the horizontal aim by your Pontiac dealer.
To check the aim, the vehicle should be properly
prepared
as follows:
a The vehicle must have a11 four tires on a! perfectly
level surface.
The vehicle should not have any snow, ice or mud
There should not be any ‘cargo or loading of the

vehicle, except it should have a full tank of gas and
one person or
160 lbs. (75 kg) on the driver’s seat.
e Tires should be properly inflated.
The horizontal indicator should read “0.”
NOTICE:
To make sure your headlamps are aimed
properly, read
all the instructions before
beginning. Failure to follow th’ese instructions
could cause damage to headlamp parts.
State inspection stations will allow a vertical reading of
plus
0.76 degrees or minus 0.76 degrees fr0m the center
of the bubble.

It is recommended that the upper limit not exceed plus
0.4 degrees from the center of the bubble. Other drivers
may flash their high beams at you if your adjustment
is
much above plus 0.4 degrees.
Tires
Your new Pontiac comes with high-quality tires made
by a leading tire manufacturer.
If you ever have
questions about your tire warranty and where to obtain
service, see your Pontiac Warranty booklet for details.
Pa - - ly maintained and imp1 ,derly L,Ld tires
are dangerous.
Overloading your tires can cause overheating
as
a result of too much friction. You could have
an air-out and
a serious accident. See “Loading
Your Vehicle” in the Index.
CAUTION: (Continued) CAUTION:

impact
-9 such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have
been damaged, replace them.
See “Inflation

for inflation pressure adjustment for higher
speed driving.
Overinflated tires are more likely to be

Inflation -- Tire Pressure
The Tire-Loading Information label, which is on the
driver’s door, shows the correct inflation pressures for
your tires when they’re cold. “Cold” means your vehicle
has been sitting for at least three hours or driven
no
more than 1 mile ( 1.6 km).
If you’ll be driving at speeds higher than
100 mph
(160 kdh) where it is legal, raise the cold inflation
pressure
of each tire to 35 psi (240 kPa). When you
end this very high-speed driving, reduce the
cold
inflation pressures to those listed on the Tire-Loading
Information label.
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
0 Too much heat
0 Tire overloading
0 Bad wear
0 Bad handling
0 B,ad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
0 Unusual wear
0 Bad handling
Rough ride
0 Needless damage from road hazards.

When to Check
Check your tires once a month or more.
uon’t forget your compact spare tire. It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure.
You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may
look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When It’s
Time for New Tires” and
“Wheel Replacement’’ later in this section for
more information. The
purpose
of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation
is the most important. See “Scheduled
Maintenance Services” in the Index for scheduled
rotation intervals.
If you don’t have P245/5OZR16 or P275/40ZR17
Goodyear Eagle GS-C tires, use the rotation pattern
shown above for your tires.
6-51

If you have P245/50ZRl6 or P27940ZR17 Goodyear
Eagle
GS-C 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 “Wheel Nut Torque” in
the Index.
I
Rust or dirt on a wheel, or on the pa; cJ to which
it is fastened, can make wheel nuts become loose
after a time.
The wheel could come off and caus’e
an accident.
When you change a wheel, remove
any rust or dirt frolm 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
“Changing a Flat Tire” in the Index.)

Traction -- A, B, C
The traction grades, from highest to lowest, are A, B,
and C, and they represent the tire’s ability to stop on
wet pavement as measured under controlled conditions
on specified government test surfaces
of asphalt and
concrete.
A tire marked C may have poor traction
performance.
Warning: The traction grade assigned to this tire is based
on braking (straightahead) traction tests and does not
include cornering (turning) traction.
Temperature -- A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire
to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure.
The grade
C corresponds to a level of performance
which all passenger car tires must meet under the Federal
Motor Vehicle Safety Standard
No. 109. Grades
B and A represent higher levels of performance on the
laboratory test wheel than the minimum required
by law.
Warning: The temperature grade for this tire
is
established for a tire that is properly inflated and
not overloaded. Excessive speed, underinflation,
or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
Scheduled wheel alignment and wheel balancing are
not needed. However, if you notice unusual tire wear or
your vehicle pulling one way or the other, the alignment
may need to be reset. If
you notice your vehicle
vibrating when driving on a smooth road, your wheels
may need to be rebalanced.

Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced.
If the
wheel leaks air, replace
it (except some aluminum
wheels, which can sometimes be repaired). See your
Pontiac dealer if any
of these conditions exist.
Your dealer will know the kind
of wheel you need.
Each new
wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels, wheel
bolts or wheel nuts, replace them only with new
CM
original equipment parts. This way, you will be sure to
have the right wheel, wheel. bolts and wheel nuts
for
your Pontiac model.
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires
lose air and make you
lose control. You could have a collision in which
you or others could be injured.
Always use the
correct wheel, wheel bolts and wheel nuts
for
replacement.
NOTICE:
~
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance
and tire or tire
chain clearance to the body and chassis.
See “Changing a Flat Tire” in the Index for more
information.
