Resynchronizing Your Transmitter
Your RFA system uses a continually changing code for
increased security. Normally, the receiver in your
vehicle will keep track of this changing code. If your
vehicle does not respond to your transmitter, do the
following to determine what's wrong:
1. Get closer to the vehicle and try pressing a button
again. Your battery may be low (If so, see ªBattery
Replacementº in the Index).
2. While standing close to your vehicle, press the
LOCK and UNLOCK buttons on your transmitter at
the same time and hold for seven seconds. This will
attempt to resynchronize the security code in your
RFA key fob transmitter.
3. When resynchronization is achieved, the horn
will chirp.
Loss of synchronization will occur after transmitter
battery replacement or disconnection of the
vehicle's battery.
If attempts to resynchronize your transmitter to the
vehicle are not successful, you may need to match the
transmitter to the vehicle. See ªMatching Transmitter(s)
to Your Vehicleº in the Index.
Remote Hatch/Trunk Lid Release
To use the remote hatch/trunk lid release on automatic
transmission vehicles, your vehicle must be in PARK (P)
or NEUTRAL (N). For manual transmissions, set the
parking brake. See ªParking Brakeº in the Index.
Press the button with the trunk symbol on it, located at
the left
-hand side of the steering column on the
instrument panel, to release the hatch/trunk lid from
inside your vehicle.

The key fob transmitter will also release the hatch/trunk lid.
See ªRemote Function Actuation Systemº in the Index.
If your vehicle is equipped with a hatch and you have
lost battery power, use the manual release cables to open
the hatch. To access the cables, remove the two access
panels located in the rear of the trunk area. There is one
cable located under each access panel. (See ªRear
Storage Compartmentsº in the Index for
more information.)
Pull each cable straight down for each latch to release
the hatch.If your vehicle is equipped with a convertible
top/hardtop and you have lost battery power, use the
manual release cable to open the trunk lid. To access the
cable, remove the center storage compartment lid
located in the rear of the trunk area. (See ªRear Storage
Compartmentsº in the Index for more information.)
Pull the cable straight down to release the trunk lid.

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.

Engine Oil Life
Press the TRIP button until the engine oil life is
displayed, such as OIL LIFE REMAIN 89%.
This is an estimate of the engine oil's remaining useful
life. It will show 99% when the system is reset after an
oil change. It will alert you to change your oil on a
schedule consistent with your driving conditions.
When the remaining oil life is low, the system will alert
you with the message CHANGE OIL SOON.
When the oil life is down to zero, you will receive the
message CHANGE OIL NOW.Remember, you must reset the OIL LIFE yourself after
each oil change. It will not reset itself. Also, be careful
not to reset the OIL LIFE accidentally at any time other
than when the oil has just been changed. It can't be reset
accurately until the next oil change.
To reset the Engine Oil Life Monitor, see ªHow to Reset
the Engine Oil Life Monitorº in the Index.
Also, see ªEngine Oil, When to Changeº and
ªMaintenance Scheduleº in the Index.
