Chemical Paint Spotting
Some weather and atmospheric
conditions can create a chemical fallout.
Airborne pollutants can fall upon and
attack painted surfaces
on your vehicle.
This damage can take two forms:
blotchy, ringlet-shaped discolorations,
and small irregular dark spots etched
into the paint surface.
Although no defect
in the paint job
causes this, Pontiac will repair, at no
charge to the owner, the surfaces of
new vehicles damaged by this fallout
condition within
12 months or 12,000
miles (20 000 km) of purchase,
whichever comes first.
Vehicle Identification Number
0
This is the legal identifier for your
Pontiac. It appears on a plate in the
front corner
of the instrument panel, on
the driver’s side. You can see it
if you
look through the windshield from
outside your vehicle. The VIN also
appears on the Vehicle Certification and
Service Parts labels
and the certificates
of title and registration.

Fuses & Circuit Breakers
The wiring circuits in your vehicle are
protected
from short circuits by a
combination of fuses, circuit breakers,
and fusible thermal links in the wiring
itself. This greatly reduces the chance
of
fires caused by electrical problems.
Some fuses are located in a fuse block
in the glove box as shown above.
To
locate the fuse block, pull down the
cover. See the diagram later in this
section.
Another set
of fuses is located in the
component center, under the
instrument panel.
Additional fuses are located in the
underhood electrical centers on the
right and left sides of the engine
compartment.
270
Spare fuses and a fuse puller are located
in the glove box fuse block cover.
Place the wide end of the fuse puller
over the plastic end of the fuse. Squeeze
the ends over the fuse and pull it out.
To identify and check fuses, refer to the
charts on the following pages. Look at the silver-colored band inside
the fuse.
If the band is broken or
melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the
identical size and rating.
