Magnesium Wheel Finish
NOTICE:
Improper paint repair or refinishing can cause
corrosion damage to a magnesium wheel. See
your dealer if a magnesium wheel needs paint
repair or refinishing.
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 other debris can collect. Dirt packed in closed areas
of the frame should be loosened before being flushed.
Your dealer or an underbody car washing system can do
this for you.
Fiberglass Springs
NOTICE:
Don't use corrosive or acidic cleaning agents,
engine degreasers, aluminum cleaning agents or
other harsh solvents to clean fiberglass springs;
they'll damage the springs.
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,
Chevrolet 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 occurs first.

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 located inside the glovebox. 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 ªServicing
Your Air Bag
-Equipped Vehicleº in the Index.
Accessory Power Plug
This plug can be used to connect electrical equipment
such as a cellular phone or CB radio. The accessory
power plug is located behind the passenger side
toe
-board at the top left corner near the body control
module. Be sure to follow the installation instructions
included with the equipment.
To use the accessory power plug:
1. Remove the toe
-board panel by lifting up on the
latches at the top of each corner of the panel.
2. Locate the black connector at the left top corner of
the compartment near the body control module
above the two white diagnostic connectors.
3. Disconnect the connector pigtail by pulling forward
on the plastic locking tab and pull the connection
apart from the wire harness.
The plug has three separate wires:

The orange wire connects to battery power.

The yellow wire connects to ignition power. Power is
only available when the ignition is in ON.

The black wire connects to ground.

NOTICE:
When using the accessory power plug:

DO NOT splice wires directly into the
vehicle electrical wire harness. If done
incorrectly, splicing may cause damage to
your electrical system and would not be
covered by the vehicle's warranty.

The maximum load of any electrical
equipment should not exceed 15 amps.

Be sure to turn off any electrical equipment
when not in use. Leaving electrical
equipment on for extended periods of time
can drain your battery.

DO NOT use this plug if the electrical
equipment requires frequent connecting
and disconnecting. This may cause
excessive wear on the accessory power plug
and damage your electrical system and
the damage would not be covered by
your warranty.
Headlamps
The headlamp wiring is protected by a circuit breaker.
An electrical overload will cause the lamps to go on and
off, or in some cases to remain off. If this happens, have
your headlamp wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by a fuse and
an internal circuit breaker. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. If the overload is caused by some electrical
problem and not snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power seats and other power
accessories. When the current load is too heavy, the
circuit breaker opens and closes, protecting the circuit
until the problem is fixed or goes away.

6-68 Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of maxi
-fuses,
mini
-fuses and circuit breakers. This greatly reduces the
chance of fires 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 you
replace a bad fuse with a new one of the identical size
and rating.
If you ever have a problem on the road and don't have a
spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle that
you can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as soon as you can.Instrument Panel Fuse Block
The instrument panel fuse
block is located on the
passenger's side of the
vehicle, under the
instrument panel and under
the toe
-board.
Remove the toe
-board and carpet covering to access the
fuse block. Then turn the fuse block door knob and pull
the door to access the fuses.
