Theft-Deterrent Systems
Vehicle theft is big business, expecially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you
can help.
Theft-Deterrent System
Your vehicle is equipped with a theft-deterrent alarm
system.
With this system, the
SECURITY light will ¯ash
as you open the door
if your ignition is off. This
light reminds you to
arm the theft-deterent
system.
Arming the System
Use one of the two following items listed here to arm
the system:
·Press the lock button on the remote keyless entry
transmitter.
·Open the door. The SECURITY light should ¯ash.
Lock the door with the power door lock switch.
The SECURITY light will stop ¯ashing and stay on.
Close the door. The security light should go off.
Now, if a door or the hatch/trunk lid is opened without
the key or the remote keyless entry transmitter, the
alarm will go off. Your horn will sound for two minutes,
then it will go off to save battery power. And, your
vehicle won't start.
The theft-deterrent system won't arm if you lock the
driver's door with a key, the manual door lock, or if you
use the power door lock 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.
2-16

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.
See
Roadside Assistance Program on page 7-6for more
information.

Rear Storage Area
There are three rear storage compartments in the ¯oor
of the rear hatch/trunk area.If you have a coupe or convertible model, your vehicle
will be equipped with three storage compartment
lids. If you have a Z06, your vehicle's three storage
compartments will not have lids.
To access a storage compartment, pull up on the
latch to release the lid. Remove the storage
compartment lid.
When replacing a storage compartment lid, make sure
the latch is in the correct location so the latch locks
securely into place. Coupe shown, Convertible and Z06 similar

Notice:If your vehicle is equipped with the optional
trunk±mounted CD changer, it is stored in the
center rear storage compartment. To help avoid
damage to the compact disc player, do not store
items such as liquids or sharp objects that could
damage, puncture or cut the trunk±mounted
CD changer or wiring.
Notice:Do not store heavy or sharp objects in the
rear storage compartments located in the

Convenience Net
If your vehicle has this feature you will see it on the
back wall of the rear area of the vehicle.
Put small loads, like grocery bags, in the net. It can help
keep them from falling over during sharp turns or
quick starts and stops. The convenience net is not for
larger, heavier loads.
You can unhook the net and place it in one of the rear
storage compartments when you are not using it.
On coupe models only, a vinyl storage bag has also
been provided.
Cargo Cover
If your vehicle has this feature, the security shade can
provide hidden storage in the rear area of the vehicle.
The shade is also helpful in blocking the glare from the
removable roof when it is stored in the rear
compartment.
Using the Cargo Cover
1. Hook the elastic loops
on the front corners (A)
of the shade to the
T-nuts located on the
front corners of the rear
hatch frame.
2. Hook the elastic loops on the rear corners (B) of the
shade to the hooks recessed inside the rear hatch
