2003 CHEVROLET CORVETTE fuse

Testing the Alarm
To test the system, do the following:
1. Make sure the hatch/trunk lid is latched.
2. Lower the window on the driver's door.
3. Manually arm the system.
4. Close the doors and wait 15 seconds.
5. Reach through the open window and manually
unlock the driver's door.
6. Open the door. The alarm should sound.
7. Turn off the alarm.
If the alarm is inoperative, check to see if the horn
works. If not, check the horn fuse. See
Fuses and Circuit
Breakers on page 5-86. If the horn works, but the
alarm doesn't go off, see your dealer.
Disarming the System
Always use your key or the remote keyless entry
transmitter to unlock a door. Unlocking a door any other
way will set off the alarm. If your alarm sounds, listed
below are the ways you can disarm it.
·Unlock the driver's door with your key.
·Put the key in the ignition.
·Press the unlock button on the remote keyless
entry transmitter.
PASS-Keyž
Your vehicle is equipped
with the
PASS-Key
ž(Personalized
Automotive Security
System) theft-deterrent
system. PASS-Key
žis a
passive theft-deterrent
system. It works when you
insert or remove the key
from the ignition.
PASS-Key
žuses a resistor pellet in the ignition key that
matches a decoder in your vehicle.
When the PASS-Key
žsystem senses that someone is
using the wrong key, it shuts down the vehicle's
starter and fuel systems. For about three minutes, the
starter won't work and fuel won't go to the engine.
If someone tries to start your vehicle again or uses
another key during this time, the shutdown period will
start over again. This discourages someone from
randomly trying different keys with different resistor
pellets in an attempt to make a match.
2-17

The key must be clean and dry before it's inserted in
the ignition or the engine may not start. If the SECURITY
light comes on, the key may be dirty or wet.
If this happens and the starter won't work, turn the
ignition off. Clean and dry the key, wait three minutes
and try again. If the starter still won't work, wait
three minutes and try the other ignition key. At this time,
you may also want to check the fuses. See
Fuses
and Circuit Breakers on page 5-86. If the starter won't
work with the other key, your vehicle needs service.
If your vehicle does start, the ®rst ignition key may be
faulty. See your dealer or a locksmith who can
service the PASS-Key
ž.If you accidentally use a key that has a damaged or
missing resistor pellet, you will see no SECURITY light.
You don't have to wait three minutes before trying
the proper key.
If the resistor pellet is damaged or missing, the starter
won't work. Use the other ignition key, and see your
dealer or a locksmith who can service the PASS-Key
žto
have a new key made.
If the SECURITY light comes on while driving, have
your vehicle serviced as soon as possible.
If you lose or damage a PASS-Key
žignition key, see
your dealer or a locksmith who can service PASS-Keyž.
In an emergency, call Chevrolet Roadside Assistance.

Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
·Turn and Lane-Change Signals
·Headlamp High/Low-Beam Changer
·Flash-to-Pass Feature
·Cruise Control
For information on exterior lamps, see
Exterior Lamps
on page 3-12.
Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the multifunction lever all the
way up or down. When the turn is ®nished, the lever will
return automatically.
An arrow on the instrument
panel cluster will ¯ash in
the direction of the
turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to ¯ash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
If you signal a turn or a lane change and the arrows
¯ash faster than normal, a signal bulb may be burned out.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you signal
a turn, check the fuses and check for burned-out
bulbs. See
Fuses and Circuit Breakers on page 5-86.

If the sun comes out or it becomes cloudy, you may
need to adjust the HUD brightness again using
the dimmer control. Polarized sunglasses could make
the HUD image harder to see.
To change from English to metric units, press the
E/M button located to the right of the steering wheel.
Clean the inside of the windshield as needed to remove
any dirt or ®lm that reduces the sharpness or clarity
of the HUD image.
To clean the HUD, spray household glass cleaner on a
soft, clean cloth. Wipe the HUD lens gently, then dry
it. Do not spray cleaner directly on the lens because the
cleaner could leak into the unit.
If the ignition is on and you can't see the HUD image,
check to see if:
·Something is covering the HUD unit.
·The HUD dimmer control is adjusted properly.
·The HUD image is adjusted to the proper height.
·Ambient light, in the direction your vehicle is facing,
is low.
·A fuse is blown. SeeFuses and Circuit Breakers on
page 5-86
.
Keep in mind that your windshield is part of the HUD
system. If you ever have to have your windshield
replaced, be sure to get one that is designed for HUD
or your HUD image may look blurred and out of focus.
Accessory Power Outlets
The accessory power outlet can be used to connect
electrical equipment such as a cellular phone or
CB radio.
The accessory power outlet is located inside the
center console storage compartment, on the forward
left side.
To use the outlet, remove the tethered cap. When not
using it, always cover the outlet with the protective cap.
Notice:When using an accessory power outlet,
maximum electrical load must not exceed 15 amps.
Always turn off any electrical equipment when
not in use. Leaving electrical equipment on for
extended periods will drain your battery.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adapter fuses. If you experience a
problem, see your dealer for additional information
on accessory power outlets.
Notice:Adding some electrical equipment to your
vehicle can damage it or keep other things from
working as they should. This wouldn't be covered by
your warranty. Check with your dealer before
adding electrical equipment, and never use anything
that exceeds the amperage rating.

Be sure to use the proper nuts, bolts and
other fasteners. ªEnglishº and ªmetricº
fasteners can be easily confused. If you
use the wrong fasteners, parts can later
break or fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the air¯ow around it. This may cause wind
noise and affect windshield washer performance. Check
with your dealer before adding equipment to the
outside of your vehicle.
Fuel
Use of the recommended fuel is an important part of the
proper maintenance of your vehicle.
Gasoline Octane
Use premium unleaded gasoline with a posted octane of
91 or higher for best performance. You may also use
middle grade or regular unleaded gasoline rated at
87 octane or higher, but your vehicle's acceleration may
be slightly reduced. If the octane is less than 87, you
may get a heavy knocking noise when you drive. If this
occurs, use a gasoline rated at 87 octane or higher
as soon as possible. Otherwise, you might damage your
engine.

covered by your warranty.
Headlamp Wiring
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 Wiper Fuses
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 ®xed.
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 ®xed or goes away.
