One key is used for the
ignition, the doors and
all other locks.
If you need a new key, contact your dealer for
assistance. In an emergency, contact Chevrolet
Roadside Assistance. See ªRoadside Assistanceº
in the Index for more information.
NOTICE:
Your vehicle has a number of features that can
help prevent theft. But you can have a lot of
trouble getting into your vehicle if you ever lock
your key inside. You may even have to damage
your vehicle to get in. So be sure you have an
extra key.
If your vehicle's equipped with the OnStar system, with
an active subscription and you lock your keys inside the
vehicle, OnStar may be able to send a command to
unlock your vehicle. See ªOnStarº in the Index for
more information.

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 won't open it. You increase the
chance of being thrown out of the vehicle in
a crash if the doors aren't 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.

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 remote keyless entry
transmitter (if equipped). From the inside, use the
manual or power door locks.
To unlock either front door from the outside with the
key, insert the key and turn it toward the front of the
vehicle. To lock either front door from the outside with
your key, insert the key and turn it toward the rear of
the vehicle.
To lock the door from the inside, push the manual
lock lever forward. To unlock the door, pull the
lever rearward.

2-7
Power Door Locks
A power door lock switch is
located on each front door
above the armrest.
Press the top part of the switch to unlock all doors, or
press the bottom part of the switch to lock all doors.
The rear doors do not have power door lock switches.
The lever on each rear door works only that door's lock.
It won't lock or unlock all the doors.
If your vehicle has the optional content theft
-deterrent
system and it is armed, the power door lock switches
will be disabled. You must use your remote keyless
entry transmitter or your key to unlock the doors when
the system is armed.
Programmable Automatic Power Door Locks
Programmable automatic power door locks are a
standard feature that is intended to provide enhanced
security and convenience by automatically locking and
unlocking doors.
Programmable Modes
Mode 1: No automatic door lock or unlock.
Mode 2: Automatic all
-door lock when the transaxle is
shifted out of PARK (P); no automatic door unlock.
Mode 3: Automatic all
-door lock when the transaxle is
shifted out of PARK (P); automatic unlock for the driver's
door only when the transaxle is shifted into PARK (P).
Mode 4: Automatic all
-door lock when the transaxle is
shifted out of PARK (P); automatic all
-door unlock
when the transaxle is shifted into PARK (P).
Before your vehicle was shipped from the factory, it was
programmed to Mode 4. The mode to which the vehicle
was programmed may have been changed since it left the
factory. To determine the mode to which your vehicle is
programmed or to program your vehicle to a different
mode, see ªVehicle Customization Settingsº in the Index.
Disconnecting the battery for up to a year will not
change the programmed mode of the programmable
automatic power door locks.

2-8 Rear-Door Security Locks
Your vehicle is equipped with rear-door security locks
that help prevent passengers from opening the rear doors
of your vehicle from the inside.
To use one of these locks do the following:
1. Open one of the rear doors.
2. On the inside of the rear
door will be a lock with
a label as shown. Slide
the lever located next
to the label upward to
engage the lock.
3. Close the door.
4. Repeat the procedure on the other rear
-door lock.To disengage the lock(s), reverse the steps.
The rear doors of your vehicle cannot be opened from
the inside when this feature is in use. If you want to
open the rear door when the security lock is on, unlock
the door and then open the door from the outside.
Lockout Protection Feature
To protect you from locking your key in the vehicle, this
feature stops the power door locks from locking when
the keys are in the ignition and a door is open.
If a power lock switch is pressed when a door is open
and the key is in the ignition, all of the doors will lock
and then the driver's door will unlock. A chime will
sound continuously until all doors are closed.
Leaving Your Vehicle
If you are leaving the vehicle, take your keys, open your
door and set the locks from inside. Then get out and
close the door.

2-9
Remote Keyless Entry (If Equipped)
If your vehicle has this feature, you can lock and unlock
your doors or unlock your trunk from about 3 feet (1 m)
up to 30 feet (9 m) away using the remote keyless entry
transmitter supplied with your vehicle.
Your remote keyless entry system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful 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.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:

Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.

Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.

Check to determine if battery replacement or
resynchronization is necessary. See the instructions
that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.

2-10 Operation
Use the remote keyless
entry transmitter to
open or lock your
vehicle's doors or
trunk from a distance.
Remote Keyless
Entry Transmitter
LOCK: Press the LOCK button to lock all the doors.
UNLOCK: Press the UNLOCK button on the remote
keyless transmitter once to unlock the driver's door and
turn on the interior lamps See ªIllumination and Remote
Activationº in the Index for more details. Pause for
about one second, then press UNLOCK again within
five seconds to unlock the passenger door.
(Panic Alarm): Press the button with the horn
symbol to activate an alarm on the remote keyless
transmitter. The ignition must be in OFF or ACC for the
panic alarm to work. When you press the panic button
on the remote keyless entry transmitter, the headlamps
will flash, the horn will honk repeatedly and your
interior lamps will illuminate attracting attention if you
need it. The alarm will continue until one of the
following occurs:

The panic alarm button on the remote keyless entry
transmitter is pressed a second time,

the vehicle's ignition is turned to ON or

an alarm period of 110 seconds has elapsed.
(Trunk Release): Press the button on the remote
keyless transmitter with the vehicle symbol on it to
release the trunk.
Operating the remote keyless entry transmitter may
interact with the content theft
- deterrent system (if your
vehicle has this option). See ªContent Theft
-Deterrent
Systemº in the Index.

2-11
Transmitter Verification (If Equipped)
This feature provides feedback to the holder of the
remote keyless entry transmitter that a command has
been received by the keyless entry receiver. The
headlamps and back
-up lamps will flash on every lock
and the first unlock command, and the horn will sound
once for every lock and twice for the first unlock
command. Silent operation and other options may be
selected for this feature (see ªVehicle Customization
Settingsº in the Index).
If your vehicle has the optional content theft
-deterrent
system, the first time the remote unlock is received,
three flashes and chirps will be seen to indicate an alarm
condition has occurred since last arming. See ªContent
Theft
-Deterrent Systemº in the Index.
Illumination on Remote Activation
This feature provides interior illumination when a
remote keyless entry unlock command is received and
executed, the trunk release button is pressed or when
the panic alarm is activated. The interior lamps will
illuminate until the ignition is turned to ON or untilan illumination period of 40 seconds has elapsed or the
doors are locked with the power door lock switch or the
remote keyless entry transmitter. If a door is opened
during the illumination period, the timed illumination
will be canceled, and the interior lamps will remain on
while the door is open.
Matching Transmitter(s) to Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have a maximum of four
transmitters matched to it.
If you prefer, you can complete this procedure yourself.
See ªVehicle Customization Settingsº in the Index for
more information.

2-12 Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about three years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's 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 do the following:
1. Insert a flat object like a coin into the slot on the
back of the transmitter. Gently pry apart the front
and back.
2. Gently pry the battery out of the transmitter. Do not
use a metal object.
3. Put the new battery into the transmitter as
shown on the transmitter (use type CR2032 battery
or equivalent).
4. Put the two halves back together. Make sure the
halves are together tightly so water won't get in.
5. Resynchronize and then test the transmitter.

2-13
Resynchronization
After you have changed the battery in your transmitter,
you will need to resynchronize the transmitter. To do
this, press the LOCK and UNLOCK buttons on the
transmitter together and hold for approximately seven
seconds or until one brief horn chirp is heard.
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't 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 with the setting
on VENT. That will force outside air into
your vehicle. See ªComfort Controlsº in
the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.

2-14 Trunk Lock
To unlock the trunk from the outside, insert the key in
the lock and turn it. You can also press the car symbol
on your remote keyless entry transmitter (if equipped).
Remote Trunk Release
You can also unlock the trunk from inside the vehicle.
Press the button located
below the exterior lamps
control on the underside of
the dashboard. The shift
lever must be in PARK (P)
for the remote trunk release
button to work.
Trunk Assist Handle
There is an assist handle located on the inside of the
trunk lid toward the driver's side of the vehicle.
