2003 CHEVROLET CORVETTE lock

{CAUTION:
It can be dangerous to get out of your vehicle
with the engine running, if the shift lever is not
in NEUTRAL (N) with the parking brake ®rmly
set (manual transmission). Your vehicle can
roll or move suddenly even when on fairly
level ground. To be sure your vehicle won't
move, always set your parking brake and move
the shift lever to NEUTRAL (N) when you start
or idle your engine.
{CAUTION:
Idling the engine in a closed-in place or with
the climate control system off can cause
deadly carbon monoxide (CO). See ªEngine
Exhaustº in the Index.
{CAUTION:
In¯ating something too much can make it
explode, and you or others could be injured.
Be sure to read the in¯ator instructions, and
in¯ate the tire to its recommended pressure.
Do not exceed 36 psi (248 kPa).
Notice:Do not allow the air compressor to operate
continuously for more than six minutes to help
prevent damage from overheating.
Notice:If 26 psi (179 kPa) tire pressure cannot be
reached after six minutes the vehicle should not
be driven further. Damage to the tire is severe and
the sealant will not be effective. Remove the air
compressor plug from the accessory power outlet
and unscrew the in¯ating hose from the tire
valve. See ªRoadside Assistanceº in the Index.
If 26 psi (179 kPa) tire pressure is reached in six
minutes or less, disconnect the air compressor and
attach the enclosed maximum speed label to the inside
upper left corner of the windshield or to the face of
the radio/clock.

Electrical System
Add-On Electrical Equipment
Notice:Don't add anything electrical to your
vehicle unless you check with your dealer ®rst.
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 1-47.
Accessory Power Plug
The accessory power plug can be used to connect
electrical equipment such as a cellular phone or
CB radio. It is located behind the carpeting, on the
passenger's 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, do the following:
1. Remove the toe-board panel by pulling at the top of
each corner of the panel.
2. Locate the black connector at the top left 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 the following 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.

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 ®res 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 carpet and toe-board covering to access
the fuse block by pulling at the top of each corner of the
panel. Then turn the fuse block door knob
counterclockwise and pull the door to access the fuses.

At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag
system does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace
blade inserts that appear worn or damaged or that
streak or miss areas of the windshield. Also see
Cleaning the Outside of Your Vehicle on page 5-78.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. See
Part D: Recommended Fluids and
Lubricants on page 6-14.
Manual Transmission Check
Check the transmission ¯uid level; add if needed. SeeManual Transmission Fluid on page 5-20. Check
for leaks. A ¯uid leak is the only reason for ¯uid loss.
Have the system inspected and repaired if needed.
Automatic Transmission Check
It is not necessary to check the transmission ¯uid level.
A transmission ¯uid leak is the only reason for ¯uid
loss. Check for leaks. If a leak occurs, take the vehicle
to your dealer and have it repaired as soon as
possible.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
speci®ed in Part D.
Body Lubrication Service
Lubricate all body door hinges. Also lubricate all hinges
and latches, including those for the hood, rear
compartment, console door and any folding seat
hardware. Part D tells you what to use. More frequent
lubrication may be required when exposed to a corrosive
environment.
