I Universal Theft
Deterrent
‘our Corvette has a theft deterrent
larm system. With this system, the
SECURITY” light will flash as you
pen the door (if your ignition is
off).
‘his light reminds you to arm the theft
eterrent system. Here’s how to do it:
. Open the door.
. Lock the door with the power door
lock switch or the Passive Keyless
Entry system. The “SECURITY” lieht
will come on.
. Close all the doors. The “SECURITY’
light should go
off.
... 44
Now, if a door or the hatch is opened
without the key or Passive Keyless Entry
system, the alarm will go
off. Your horn
will sound for three minutes, then it will
go
off to save battery power.
The theft deterrent system won’t
arm if
you lock the doors with a key or manual
door lock, or if you lock the vehicle after
the doors are closed.
If your passenger stays in the vehicle
when you leave with the keys, have the
passenger lock the vehicle after the doors
are closed. This way the alarm won’t
arm,
and your passenger won’t set it off.
Always use your key or the Passive
Keyless Entry system to unlock a door.
Unlocking a door any other way will set
off the alarm.
If you do set off the alarm
accidentally, there are three ways to stop
it:
Unlock any door with your key.
Put the ignition key in the ignition.
Use the Passive Keyless Entry system.
How to Test the Alarm
1. Make sure the rear hatch is latched.
2. Lower a window.
3. Arm the system.
4. Close the doors and wait five seconds.
5. Reach through the open window and
unlock the door from inside. The
alarm should sound.
6. Turn off the alarm.
If the alarm doesn’t go
off, check to see
if the horn works. If not, check the horn
fuse. See “Fuses and Circuit Breakers” in
the Index. If the horn does work, but the
alarm doesn’t go
off, see your dealer.

PASS-Key@
Your vehicle is equipped with the
PASS-Key@ (Personalized Automotive
Security System) theft deterrent system.
PASS-Key@ is a passive theft deterrent
system. This means you don’t have to do
anything different to arm or disarm the
system. It works when you insert or
remove the key from the ignition.
PASS-Key@ uses a resistor pellet in
the ignition key that matches a decoder
in your vehicle. When the PASS-Key@ system
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.
The ignition 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’’ in
the Index). If the starter won’t work with the
other key, your vehicle needs service.
[f your vehicle does start, the first ignition
key may be faulty. See your Chevrolet
Jealer or a locksmith who can service the
PASS-Key@
However, 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
OF
missing, the starter won’t work. Use the
other ignition key, and see your Chevrolet
dealer or a locksmith who can service the
PASS-Key@ to 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@
ignition key, see your Chevrolet
dealer or a locksmith who can service
PASS-Key@. In an emergency, call the
Chevrolet Roadside Assistance Program
at
1 -800-CHEV USA (1 -800-243-8872).

A green arrow on the instrument panel
will flash in the direction of the
turn or
lane change.
To signal a lane change, just raise or
lower the lever until the green arrow start
to flash. Hold it there until you complete
your lane change. The lever will return b!
itself when you release
it.
As you signal a turn or a lane change, if
the arrows don’t flash but just stay on, a
signal bulb may be burned out and other
drivers won’t see your
turn signal.
If a bulb is burned out, replace it to help
avoid an accident.
If the green arrows
don’t go on at all when you signal a
turn,
check the fuse (see “Fuses” in the Index)
and for burned-out bulbs.
Headlight High/..ow Beam
To change the headlights from low beam
to high or high to low, pull the turn signal
lever all the way toward you. Then
release it. When the high beams are on,
this blue light on the instrument panel
also will be on.
Windshield Wipers
You control the windshield wipers by
turning the band with the wiper symbol
on it.
For a single wiping cycle,
turn the band
to “MIST.” Hold it there until the wipers
start, then let go. The wipers will stop
after one cycle. If you want more cycles,
hold the band on “MIST” longer.
You can set the wiper speed for a long or
short delay between wipes. This can be
very useful in light rain or snow. Turn the
band to choose the delay time. The closer
to
“LO,” the shorter the delay.

System Problems

is added, until the
system is reset. Have your system
checked and serviced
if needed.

Downloaded from www.Manualslib.com manuals search engine 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.
There are three fuse centers on your
vehicle. One
is in the right side of your
instrument panel. Turn the knob and pull
the door to access the fuses. The other
two fuse blocks are in the
engine compartment. One is part of the
Forward Lamp wiring harness
(A), and
the other is part of the ECM-Engine
wiring harness
(B).
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 correct
size.
If you ever have a problem on the road
and don’t have a spare fuse, you can
borrow one of the correct value. 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 size you need. Replace it as soon
as you can.
Headlights
The headlight wiring is protected by a
circuit breaker
in the switch. An electrical
overload will cause the lights to go on and
off, or in some cases to remain
off. If this
happens, have your headlight wiring
checked right away.
Windshield Wipers
The windshield wiper motor is protected
by a circuit breaker and a fuse. 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
windows 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.
