Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the LED fails to
illuminate or if the transmitter will not work at the normal
range in any location. If you have to get close to your
vehicle before the transmitter works, it is probably
time to change the battery.
Notice:When replacing the battery, use care not
to touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.To replace the battery in the remote keyless entry
transmitter, do the following:
1. Remove the screw from the back of the cover and
open the cover of the transmitter.
2. Pull the transmitter out of the cover and carefully
detach the sticker from the unit. Keep the sticker
clean.
3. Remove the battery and replace it with the new
one. Make sure the positive side of the battery
faces up. Use one three-volt, CR1620, or
equivalent, type battery.
4. Attach the sticker and put the transmitter unit in
the cover.
5. Put the two halves back together and replace the
screw. Make sure the cover is on tightly, so water
will not get in.
6. Test the transmitter operation.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers — especially children — can
easily open the doors and fall out of a
moving vehicle. When a door is locked,
the handle will not open it. You increase
the chance of being thrown out of the
vehicle in a crash if the doors are not
locked. So, wear safety belts properly and
lock the doors whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
CAUTION: (Continued)
CAUTION: (Continued)

Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.
There are several ways to lock and unlock your vehicle.
From the outside, use your key or the remote keyless
entry transmitter. SeeRemote Keyless Entry System
Operation on page 2-5.
To manually unlock the doors from the outside, insert
the key and turn it toward the front of the vehicle.
To manually lock the doors from the outside, insert the
key and turn it toward the rear of the vehicle.
All doors, except the driver’s door, can be locked from
the outside by pushing down the manual door lock
and then closing the door. The driver’s door lock cannot
be pushed in while the door is opened.
Upon leaving the vehicle, the driver’s door can only be
locked from the outside by using the key or the
remote keyless entry transmitter.

the upper surface be used to close the trunk.
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can not see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.

Theft-Deterrent Systems
Vehicle theft is big business, especially 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.
Theft-Deterrent System
Your vehicle has a theft-deterrent system.
The theft-deterrent system will not arm when you lock the
doors using the key or the manual door lock. It activates
only when you use the remote keyless entry transmitter.
Arming the System
To arm the system, do the following:
1. Turn the key to LOCK and remove the key from
the ignition.
If the key is inserted in the ignition, the transmitter
will not operate the theft-deterrent system.
2. Close the doors, the windows, the hood, and
the trunk.
Ensure that the windows are closed, as the system
can be activated even if the windows are open.3. Lock the door using the remote keyless entry
transmitter. The transmitter must be used to activate
the theft-deterrent system.
•The LED on the transmitter will flash.
•All of the doors will lock.
•The hazard warning lamps will flash once and
the horn will chirp.
•The theft-deterrent mode will arm.
•The security light will flash once every second to
indicate that the theft-deterrent system is armed.
The security light is located on the top center
of the instrument panel, near the windshield.
To avoid activating the alarm by accident, do one of
the following:
•Unlock the driver’s or passenger’s front door using
the key.
•Press the lock/unlock button on the remote keyless
entry transmitter.
Unlocking a door any other way will activate the alarm
when a door or the trunk is opened.
If you do not want to arm the theft-deterrent system,
lock the vehicle using the key or the manual door locks.
2-15

Disarming the System
To disarm the system, do one of the following:
•Unlock the driver’s or passenger’s front door using
the key.
•Press the lock/unlock button on the transmitter.
- The LED on the transmitter will flash.
- All of the doors will unlock.
- The hazard warning lamps will flash twice.
- The theft-deterrent mode will disarm.
If the door is not opened or if the engine is not started
within 30 seconds after disarming the system with
the transmitter, all of the doors will automatically lock
and the theft-deterrent mode will re-arm.
How the System Alarm is Activated
If a door or the trunk is opened without using the key
or the remote keyless entry transmitter, the horn
will sound and the lamps will flash for up to 30 seconds.
How to Turn Off the System Alarm
If the system alarm is active, it can be deactivated using
one of the following methods:
•Press the lock/unlock button on the remote keyless
entry transmitter.
•Unlock the driver’s or passenger’s front door using
the key.
Otherwise, the alarm will automatically stop after
30 seconds. The system will then lock the doors and
reactivate the theft-deterrent system.
How to Detect a Tamper Condition
If the hazard lamps flash once when the lock/unlock
button on the remote keyless entry transmitter is
pressed, the theft-deterrent system alarm was activated
while you were away.

Immobilizer
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. this device may not cause interference, and
2. this device must accept any interference received,
including interference that may cause undesired
operation.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. this device may not cause interference, and
2. this device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
Immobilizer Operation
Your vehicle may have a passive theft-deterrent system.
The immobilizer system prevents your vehicle from
being started by unauthorized persons.
If your vehicle has an immobilizer system, your vehicle
has a special key that works with the theft-deterrent
system. There is a transponder in the key head that is
electronically coded. The correct key will start the
vehicle. An invalid key immobilizes the engine. The
immobilizer system isolates the power supply to
the ignition system, the fuel pump and the fuel injectors.
The engine immobilizer is activated after the key is turned
to LOCK and removed from the ignition. The security light
located on the top center of the instrument panel, near
the windshield, will flash when the immobilizer is active. If
the light does not flash after removing the key, have the
system checked by your dealer.
The immobilizer system works when you turn the key to
START. If the immobilizer system does not recognize the
electronic code, the engine will not start and the security
indicator will continue blinking. If your key is ever
damaged, you may not be able to start your vehicle.
2-17

When trying to start the vehicle, if the engine does
not start and the security light continues flashing, the
key may have a damaged transponder. Turn the ignition
off and try again.
If the engine still does not start, and the key appears to
be undamaged, try another key. At this time, you may
also want to check the fuse. SeeFuses and Circuit
Breakers on page 5-79. If the engine still does not start
with the other key, your vehicle needs service. If your
vehicle does start, the first key may be faulty. See your
dealer who can service the theft-deterrent system to
have a new key made.
Up to four keys may be programmed for the vehicle.
If you lose or damage your keys, only a GM dealer
can service the theft-deterrent system to have new
keys made.
If you are ever driving and the security light comes on
and stays on, you will be able to restart your engine
if you turn it off. The theft-deterrent system, however,
is not working properly and must be serviced by
your dealer. Your vehicle is not protected by the
theft-deterrent system at this time.
In an emergency, contact Chevrolet Roadside
Assistance. SeeRoadside Assistance Program

New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
“break-in.” But it will perform better in the long run
if you follow these guidelines:
Do not drive at any one speed — fast or
slow — for the rst 500 miles (805 km).
Do not make full-throttle starts.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time
your new brake linings are not yet broken in.
Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every time
you get new brake linings.
Do not tow a trailer during break-in.
SeeTowing a Trailer on page 4-35for
more information.
