Compact Spare Tire
Although the compact spare 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 1tPa). The compact spare is
made to go up to 3,000 miles (5 000 lm),
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. Your anti-lock brake
system warning light may come on
when
you are driving with a compact
spare. See the
Index under Anti-Lock
Brake System Warning Light.

Problems on the Road
if You’re Stuck: In Sand, Mud, Ice
~ or Snow
What you don’t want to do when your
vehicle is stuck
is to spin your wheels.
The method known as “rocking” can
help
you get out when you’re stuck, but
you must use caution.
CAUTION
~ Spinning your wheels can destroy
parts
of your vehicle as well as the
tires.
If you spin the wheels too
fast while shifting your transaxle
back and forth, you can destroy
your transaxle.
If
you let your tires spin at
b high speed, they can explode
llyu you or others could be injured.
And, the transaxle or other parts of
the vehicle can overheat. That
could cause an engine compartment
fire
or other damage. When you’re
stuck, spin the wheels as little
as
possible. Don’t spin the wheels
above
35 mph (56 h/h) as shown
on the speedometer.
I
Rocking Your Vehicle to Get it Out:
First, turn your steering wheel left and
right. That will clear the area around
your front wheels. Then shift back and
forth between
R (Reverse) and a
forward gear (or with a manual
transaxle, between First or Second gear
and Reverse), spinning the wheels as
little as possible. Release the accelerator
pedal while you shift, and press lightly
on the accelerator pedal when the
transaxle is in gear.
If that doesn’t get
you out after a few tries, you may need
to be towed out.
If you do need to be towed out, see the
Index under Towing Your Pontiac.

Checking Aim of the Headlights
@-DOOR MODELS)
Your vehicle has the 55 x 135 mini-
quad headlight system. These
headlights have horizontal and vertical
aim indicators. The aim has been preset
at the factory and should need no
further adjustment.
To check the aim, the vehicle should be
properly prepared as follows:
The vehicle must have all four tires on
a perfectly level surface.
The vehicle should not have any
snow, ice or mud attached to it.
There should not be any cargo or
loading of vehicle, except it should
have a full tank of gas and one person
or
160 pounds (75 kg) on the driver’s
seat.
Tires should be properly inflated.
The horizontal indicator (A) should
read
0 (zero).

could cause damage to headlight
parts.
State inspection stations will allow a
vertical reading of up plus .76 degrees
or down minus
.76 degrees €or the
center of the bubble.
It is recommended that the upper limit
not exceed up plus
.4 degrees for the
center of the bubble. There may be
an
increased chance of being flashed if
adjustment is much above
up plus
.4 degrees.

Loading Your Vehicle
Two labels on your vehicle show how
much weight it may properly carry. The
Tire-Loading Information label found
on the inside of the trunk lid tells you
the proper size, speed rating 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.
The other label is the Certification label,
found on the rear edge of the driver’s
door. It tells you the gross weight
capacity of your vehicle, called the GVWR
(Gross Vehicle Weight Rating).
The GVWR includes the weight of the
vehicle, all occupants, fuel and cargo.
Never exceed the GVWR for your
vehicle, or the Gross Axle Weight
Rating (GAWR) for either the front or
rear axle.
And,
if you do have a heavy load, you
should spread it out. Don’t carry more
than
167 lbs. (75 kg) in your trunk.

Overinflated tires are more Likely to be cut, punctured, or broken by a sudden
impact, 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.
Underinflated tires pose the same danger as overloaded tires. The resulting
