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.

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.

2-18
Servicing the Trunk Release Sensor
The sensor lens should be inspected periodically. If the
lens is dirty, wipe it gently with a clean, soft cotton cloth.
If there is an electrical problem with the sensor, the
SERVICE VEHICLE SOON message will appear in the
message center. There are other possible reasons for this
message to appear. Be sure to see your dealer as soon as
possible. See ªService Vehicle Soon Messageº in the
Index for more information.
Theft
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. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.
Your ignition and transaxle will be locked. And
remember to lock the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
Even if you park in a lot where someone will be
watching your vehicle, it's still best to lock it up and
take your keys. But what if you have to leave your
ignition key?

If possible, park in a busy, well
-lit area.

Put your valuables in a storage area, like your trunk
or glove box.

Be sure to close and lock the storage area.

Close all windows.

Lock the glove box.

Lock all the doors except the driver's.

Then take the door key and remote keyless entry
transmitter with you.

2-19
Content Theft-Deterrent (Option)
Your vehicle may have the optional content
theft
-deterrent alarm system.
With this system, a light on the radio will flash.
This light reminds you to activate the theft
-deterrent
system. Here's how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or the
remote keyless entry transmitter. The light on the
radio should come on and stay on. If you are using
the remote keyless entry transmitter, the door does
not need to be open.
3. Close all doors. The light on the radio will slowly
flash once the system is armed.
Once armed, the alarm will go off if someone tries to
enter the vehicle (without using the remote keyless entry
transmitter or a key) or turns the ignition on with an
incorrect key. The horn will sound and the headlamps and
back
-up lamps will flash for approximately two minutes.When the alarm is armed, the trunk may be opened with
the remote keyless entry transmitter. If you use the key
to open the trunk, the alarm will sound. The power door
lock switches are also disabled. You must use your
remote keyless entry transmitter or your key to unlock
the doors when the system is armed.
Arming with the Power Lock Switch
Your alarm system will arm when you use either power
lock switch to lock the doors while any door or the trunk
is open and the key is removed from the ignition.
The light on the radio flashes quickly to let you know
when the system is ready to arm with the power door
lock switches. The light on the radio will stop flashing
and stay on when you press the bottom of the power
lock switch, to let you know the system is arming.
After all doors and the trunk are closed and locked, the
light on the radio will flash slowly to let you know the
system is armed.

2-20 Arming with the Remote Keyless
Entry Transmitter
Your alarm system will arm when you use your remote
keyless entry transmitter to lock the doors, if the key is
not in the ignition. The light on the radio will turn on to
let you know the system is arming. After all doors and
the trunk are closed and locked, the light on the radio
will begin flashing at a very slow rate to let you know
the system is armed.
Disarming with the Remote Keyless
Entry Transmitter
Your alarm system will disarm when you use your
remote keyless entry transmitter to unlock the doors.
The light on the radio will go off to let you know the
system is no longer armed.
The first time a remote UNLOCK command is
received, three flashes will be seen and three horn chirps
heard to indicate an alarm condition has occurred since
last arming.
Disarming with Your Key
Your alarm system will disarm when you use your key
to unlock the doors. The light on the radio will go off to
let you know the system is no longer armed.
