If the alarm is sounding because an incorrect ignition
key was used, press any button on the remote keyless
entry transmitter to turn the alarm off.
The alarm will stop by itself after two minutes.
Shock Sensor
Coupe ConvertibleThe shock sensor is what triggers the alarm when it
detects a blow to your vehicle. It is located over the
right rear wheelhouse near the spare tire in the hatch
area. There are two levels of alarms via the shock
sensor. Two horn blasts and parking lamp flashes for
non
-threatening blows to the vehicle and a full
two
-minute alarm for harder blows to the vehicle. Its
sensitivity can be adjusted if more or less sensitivity is
desired. If sensitivity is increased too much, it may give
false alarms caused by gusts of wind or other natural
events that may shake the vehicle.
To adjust, remove the label covering the adjustment
knob and adjust as desired. Turn the knob clockwise to
increase sensitivity and counterclockwise to decrease
sensitivity. The shock sensor is ignored by the alarm
system when the ignition is on, when the hatch is open,
when the alarm is disarmed, when customized to be
ignored and for five seconds after the horn sounds an
alarm or chirp. The shock sensor is ignored after
triggering three full alarms until the system is rearmed.

2-15 Arming the System
The alarm system can be armed to detect break-ins by
locking your vehicle with the remote keyless entry
transmitter or by locking the doors with the power door
lock switch.
Passive arming is also available if you would like the
system to arm all by itself after the doors have been
closed for a short time. When the system is armed, a red
light located on top of the instrument panel will flash
briefly once every two seconds. If you return to your
vehicle and the red light is flashing two brief flashes
every two seconds, the system is armed and the shock
sensor had triggered a two minute alarm. If the red light
is flashing three times every two seconds, the system is
armed and there was an intrusion that sounded the
alarm. Horn chirps and parking lamp flashes can be set
to your choice. See ªFeature Customizationº in
the Index.
Remote Keyless Entry Transmitter Locking
If all the doors are closed, locking the vehicle with the
remote keyless entry transmitter will immediately arm
the system. The horn will chirp twice and the parking
lamps will flash, confirming that the system is armed. If
any door is open when the transmitter LOCK button is
pressed, the system goes into an armed wait mode,
waiting for the doors to close. Once they are closed, the
system will arm, the horn will chirp twice and the
parking lamps will flash. If the hatch is open or ajar at
the time the system is arming, the horn will only
chirp once.
Power Door Lock Switch Locking
If any door is open when the power door lock switch is
pressed, the system goes into an armed wait mode,
waiting for the doors to close. Once they are closed, the
system will arm and the parking lamps will flash. If both
doors are closed when the lock switch is pressed, the
system assumes you are inside the vehicle, so it will not
arm. Locking the doors by using the manual door locks
will not arm the system.

yellowblue
2-16 Passive Arming
If the ignition was just turned off and a door was
opened, the system will arm six seconds after both doors
are closed, whether or not you lock them. In all other
cases, the system will wait 30 seconds after both doors
are closed before arming, allowing you time to get into
the vehicle and put the key in the ignition. The parking
lamps will flash when the system arms. Passive arming
is not enabled from the factory.
Disarming the System
There are two ways to disarm the system:
1. Press the UNLOCK button on the remote keyless
entry transmitter. If the horn chirps two or three
times when you unlock the car, the alarm sounded in
your absence. Two chirps means that the shock
sensor was set off and three chirps means that a door
or the hatch was opened.
2. Turn the ignition key to RUN.

PASS-Key II
Your vehicle is equipped
with the PASS
-Key II
(Personalized Automotive
Security System)
theft
-deterrent system.
PASS
-Key II is a passive
theft
-deterrent system.
It works when you insert
or remove the key from
the ignition.
PASS
-Key II uses a resistor pellet in the ignition key
that matches a decoder in your vehicle.
When the PASS
-Key II 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 vehicle will not start. This
discourages someone from randomly trying different
keys with different resistor pellets in an attempt to make
a match.

2-17
The ignition key must be clean and dry before it's
inserted in the ignition or the engine may not start. If the
engine does not start and the SECURITY light stays on
when you try to start the vehicle, the key may be dirty or
wet. Turn the ignition off.
Clean and dry the key. Wait about three minutes and try
again. The SECURITY light may remain on during this
time. If the starter still won't work, and the key appears
to be clean and dry, wait about three minutes and try
another ignition key. At this time, you may also want to
check the fuses (see ªFuses and Circuit Breakersº in the
Index). If the starter won't work with the other key, your
vehicle needs service. If your vehicle does start, the first
ignition key may be faulty. See your dealer or a
locksmith who can service the PASS
-Key II.If you accidentally use a key that has a damaged or
missing resistor pellet, the starter won't work. The
SECURITY light will flash. But you don't have to wait
three minutes before trying another ignition key.
See your dealer or a locksmith who can service the
PASS
-Key II to have a new key made.
If you're ever driving and the SECURITY light comes
on and stays on, you will be able to restart your engine
if you turn it off. Your PASS
-Key II system, however,
is not working properly and must be serviced by your
dealer. Your vehicle is not protected by the
PASS
-Key II system.
If you lose or damage a PASS
-Key II ignition key, see
your dealer or a locksmith who can service PASS
-Key II
to have a new key made. In an emergency, call the
Chevrolet Roadside Assistance Center at

-800-CHEV-USA or 1-800-243-8872 (In Canada
