You can turn on the passive feature by moving the
transmitter's slider switch to ON. Now, when you move
toward your vehicle with the key fob transmitter, the
system will automatically disarm your theft
-deterrent
system and unlock the driver's door or both depending
on how the system is programmed. If it's dark enough
outside, your interior lamps will come on.
You can also use the buttons on the transmitter to
actively unlock your vehicle. Press UNLOCK once to
unlock the driver's door, or press UNLOCK again
within 10 seconds to unlock both doors.
Your memory settings will also be recalled when you
press the active door UNLOCK button on the key
fob transmitter. See ªMemoryº in the Index for
more information.
The hatch/trunk lid will unlock when the button with the
trunk symbol is pressed, as long as the ignition is turned
to OFF.If you move out of range with the slider switch set to
ON, the key fob transmitter will:

Lock both doors after five seconds.

Arm the theft-deterrent system.

Sound the horn and/or flash the exterior lamps to let
you know the doors are locked (if you have set your
options to do so). See ªDriver Information Center
Controls and Displaysº in the Index.

Turn off the interior lamps.
The system has a feature that makes it difficult for you
to lock your keys in your vehicle. If you leave your keys
in the ignition and attempt to lock the doors, the vehicle
will not lock and a chime will sound to remind you that
the keys are in the ignition. If the door lock is pressed
again, within five seconds, the doors will lock and the
keys can be locked in the vehicle. If you leave the keys
in the ignition and move away with the key fob
transmitter, the doors still will not lock. You should
notice that the horn doesn't sound.

The system will allow you to lock your keys in the
vehicle if you didn't leave them in the ignition (for
example, you leave the keys on the seat). You should,
however, be able to use the key fob transmitter to get
them out as long as the passive slide switch is in the ON
position. After 15 seconds of no motion, the key fob
transmitter shuts down to save the battery. Wait about
30 seconds, then rock the vehicle. The key fob
transmitter should ªwake upº and unlock the doors.
This system can't guarantee that you will never be
locked out of your vehicle. If the battery is low or if the
key fob transmitter is in a place where the signal can't
get to the antenna, it won't unlock the doors. Always
remember to take your keys with you.
Panic Alarm Button
When you press the special horn button on the key fob
transmitter, the horn will sound. This panic alarm button
will allow you to attract attention, if needed.
If the horn alarm sounds, there are three ways to turn
it off:

Push the panic alarm button again on the key
fob transmitter.

Wait 90 seconds, and the horn will turn off by itself.

Turn the key to any position in the ignition,
except OFF.RFA Settings
You can adjust the settings on the system through the
Driver Information Center (DIC). You can have just the
driver's or both doors lock passively unlock, change the
type of alarm used by the theft
-deterrent system, or have
the lamps come on when you approach the vehicle. See
ªDriver Information Center Controls and Displaysº in
the Index for more information.
Turning the System Off
You can disable the passive feature by moving the
transmitter's slider switch to OFF. The vehicle will no
longer automatically disarm your theft
-deterrent system
or unlock the doors. However, you will be able to
actively control the use of the door locks, the
hatch/trunk lid release and the panic alarm using the
four transmitter buttons. (These buttons also work
when the passive feature is on.)
Make sure to fully slide the switch to either side when
turning the key fob transmitter on and off. You
should feel a double click when sliding the switch back
and forth.
You can also check whether the passive system is on or
off by closing the door and moving away from the
vehicle with the key and key fob transmitter. If the doors
lock, the passive system is on.

If you are working around your vehicle and keeping
your keys with you, you might want to turn the RFA
passive system off. If you don't, the transmitter will
keep locking and unlocking your doors.
Transmitter RangeThe active range (using one of the four buttons) of the
key fob transmitter is approximately 60 to 100 feet
(18 to 30 m). The passive range (having the slider
switch set to ON) is approximately 10 to 20 feet
(3 to 6 m) on the passenger's side of the vehicle and
20 to 30 feet (6 to 9 m) on the driver's side.
Matching Transmitter(s) To Your Vehicle
Each key fob 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 only three transmitters
matched to it.

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 steering wheel will be locked, and so will your
ignition. If you take the key with you, and you have an
automatic transmission, it 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
If you park in a lot where someone will be watching
your vehicle, it's best to lock it up and take your keys.
But what if you have to leave your key? Do not leave
valuables in your vehicle, since there would be no place
to secure them.
Universal Theft-Deterrent System
Your vehicle has
a theft
-deterrent
alarm system.
With this system, the SECURITY light will flash as you
open the door (if your ignition is off). This light reminds
you to arm the theft
-deterrent system.

Arming the System
Use one of the following items listed here to arm
the system:

Press the LOCK button on the key fob transmitter,

Walk out of range with the passive switch on, or

Open the door. (The SECURITY light should flash.)
Lock the door with the power door lock switch. The
SECURITY light will stop flashing and stay on.
Close the door. The SECURITY light should go off.
Testing the Alarm
Use the following to test the system:
1. Make sure the hatch/trunk lid is latched and set the
passive switch on the key fob transmitter to OFF.
2. Lower a window on the door.
3. Manually arm the system.
4. Close the doors and wait 15 seconds.
5. Reach through the open window and unlock the
door. Now open the door. The alarm should sound.
6. Turn off the alarm.If the alarm is inoperative, check to see if the horn
works. If not, check the horn fuse. See ªFuses and
Circuit Breakersº in the Index. If the horn works, but the
alarm doesn't go off, see your dealer.
Disarming the System
Always use your key or the key fob 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 any door with your key.

Put the key in the ignition.

Press the UNLOCK button on the key
fob transmitter.

Walk into range with the passive switch on.

Now, if a door or the hatch/trunk lid is opened without
the key or the key fob 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
doors 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.
PASS-Key

Your vehicle is equipped
with the PASS
-Key
(Personalized Automotive
Security System)
theft
-deterrent system.
PASS
-Key is a passive
theft
-deterrent system. It
works when you insert or
remove the key from
the ignition.PASS
-Key uses a resistor pellet in the ignition key that
matches a decoder in your vehicle.
When the PASS
-Key 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 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.
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 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.

ACC: This is an on position in which you can operate
your electrical power accessories. With the key in this
position, the automatic transmission and steering
column will unlock.
ON: This is the position to which the switch returns
after you start the engine and release the switch. The
switch stays in ON when the engine is running. But even
when the engine is not running, you can use ON to
operate your electrical power accessories and to display
some instrument panel messages and telltales.
START: This position starts the engine. When the
engine starts, release the key. The ignition switch will
return to ON for normal driving.
When the engine is not running, ACC and ON allow you
to operate your electrical accessories, such as the radio.
A warning tone will sound if you open the driver's door
when the ignition is in OFF or ACC and the key is in
the ignition.
CAUTION:
Removing the key from the ignition switch will
lock the steering column and result in a loss of
ability to steer the vehicle. This could cause a
collision. If you need to turn the engine off while
the vehicle is moving, turn the key to ACC.
NOTICE:
If your key seems stuck in OFF and you can't
turn it, be sure you are using the correct key; if
so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break
the key or the ignition switch. If none of this
works, then your vehicle needs service.

Headlamp Doors
The headlamp doors are designed to open when you turn
the headlamps on, and close when you turn the
headlamps and parking lamps off. If you turn the
headlamps on, then turn the headlamp switch back to
the parking lamps setting, the headlamp doors will
stay open.You can open the doors manually using the knob next to
the headlamp assembly. Turn the knob counterclockwise
until the doors are open.
The headlamp doors should be open when driving in icy
or snowy conditions to prevent the doors from freezing
closed and when washing the vehicle to help clean
the headlamps.
NOTICE:
In order to avoid possible contact of the hood to
the headlamp doors, care should be taken in
raising the hood with the headlamps up, or shut
off the headlamps prior to opening the hood.
