PONTIAC GRAND AM 2003 Owners Manual

Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on the underbody.
If these are not
removed, accelerated corrosion (rust) can occur on
the underbody parts such as fuel lines, frame, floor pan
and exhaust system even though they have corrosion
protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud
and debris can collect. Dirt packed in close areas of
the frame should be loosened before being flushed.
Your dealer or an underbody car washing system can
do this for you.
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.

Vehicle Identification
Vehicle Identification Number (VIN)
This is the legal identifier for your vehicle. 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.
Engine Identification
The 8th character in your VIN is the engine code.
This code will help you identify your engine,
specifications and replacement parts.
Service Parts Identification Label
You’ll find this label on the bottom of your spare
tire cover. It’s very helpful
if you ever need to order
parts. On this label is:
your VIN,
the model designation,
paint information and
a list of all production options and special
equipment.
Be sure that this label is not removed from the vehicle.

Electrical System
Add-On Electrical Equipment
Notice: Don’t add anything electrical to your
vehicle unless you check with your dealer first.
Some electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment can
keep other components from working as they
should.
Your vehicle has an air bag system. Before attempting
to add anything electrical to your vehicle, see
Servicing Your Air Bag-Equipped Vehicle on page 1-59.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
the overload is caused by some electrical problem, have
it fixed.
SXLY, ek., the vvipec vviii Sup urliii iikle I~IIU~WI cuuis. ii
Power Windows and Qther Power
Options
A circuit breaker in the fuse panel protects the power
windows. When the current load is
too heavy, the circuit
breaker opens and closes, protecting the circuit until
the problem is fixed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination
of fuses, circuit breakers
and fusible links. This greatly reduces the chance of
damage caused by electrical problems.
Look at the silver-colored band inside the fuse.
If the
band is broken or melted, replace the fuse. Be sure
to
replace a bad fuse with a new one of the identical
size and rating.
There are three fuse blocks in your vehicle: two
instrument panel fuse blocks and the engine
rmpsrtment !LE? h!r\Ck.
There are four spare fuses located in the driver’s side
instrument panel end cap for your use.
Instrument Panel Fuse Blocks
There are two fuse panels for your vehic!~. One Is
located on the driver’s side of the instrument panel
the other
is located on the passenger’s side. and
