To replace the battery in the RKE transmitter, do
the following:
1. Insert a thin object, such as a coin, in the slot
between the covers of the transmitter housing
near the key ring hole. Remove the bottom
by twisting the coin.
2. Remove and replace the battery with a
three-volt CR2032 or equivalent battery,
positive (+) side up.3. Align the covers and snap them together.
4. Resynchronize the transmitter. See
“Resynchronization” following this information.
5. Check the operation of the transmitter.
Resynchronization
Resynchronization may be necessary due to the
security method used by this system. The
transmitter does not send the same signal twice to
the receiver. The receiver will not respond to a
signal that has been sent previously. This prevents
anyone from recording and playing back the
signal from the transmitter.
To resynchronize your transmitter, stand close to
your vehicle and press and hold the lock and
unlock buttons on the transmitter at the same time
for 15 seconds. The door locks should cycle to
conrm synchronization. If the locks do not cycle,
see your dealer for service.

Content Theft-Deterrent
Your vehicle is equipped with a content
theft-deterrent alarm system.
With this system, the
security light in the
instrument panel cluster
will ash as you open
the door if your
ignition is off.
This light reminds you to activate the
theft-deterrent system. Here is 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
security light will illuminate to inform the driver
the system is arming. If a door is open when
the doors are locked, the security light
will ash.3. Close all doors. The security light should go
off after about 30 seconds. The alarm is not
armed until the security light goes off.
If the delayed locking feature is turned on,
the theft-deterrent system will not start
the arming process until the last door is
closed and the delay timer has expired.
SeeDelayed Locking on page 102.
If a locked door is opened without the key or
the remote keyless entry transmitter, the alarm will
go off. The headlamps and parking lamps will
ash for two minutes, and the horn will sound for
30 seconds, then will turn off to save the battery
power. You can choose different feedback options
for the alarm. SeeDIC Vehicle Customization
on page 234.
Remember, the theft-deterrent system will not
activate if you lock the doors with the vehicle’s key
or use the manual door lock. It activates only if
you use a power door lock switch with the
door open, or with the remote keyless entry
transmitter. You should also remember that you
can start your vehicle with the correct ignition key if
the alarm has been set off.
116

Here is how to avoid setting off the alarm
by accident:
If you do not want to activate the
theft-deterrent system, the vehicle should be
locked with the door keyafterthe doors
are closed.
Always unlock a door with a key, or use the
remote keyless entry transmitter. Unlocking
a door any other way will set off the alarm.
If you set off the alarm by accident, unlock any
door with the key. You can also turn off the alarm
by pressing unlock on the remote keyless entry
transmitter. The alarm will not stop if you try
to unlock a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver’s
window and open the driver’s door.
2. Activate the system by locking the doors with
the power door lock switch while the door is
open, or with the remote keyless entry
transmitter.
3. Get out of the vehicle, close the door and wait
for the security light to go out.
4. Then reach in through the window, unlock the
door with the manual door lock and open the
door. This should set off the alarm.
While the alarm is set, the power door unlock
switch is not operational.
If the alarm does not sound when it should but the
headlamps ash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
seeInstrument Panel Fuse Block on page 504
andUnderhood Fuse Block on page 507.
If the alarm does not sound or the headlamps do
not ash, the vehicle should be serviced by
your dealer.
117

Passlock®
Your vehicle is equipped with the Passlock®
theft-deterrent system.
Passlock
®is a passive theft-deterrent system.
Passlock®enables fuel if the ignition lock cylinder
is turned with a valid key. If a correct key is not
used or the ignition lock cylinder is tampered with,
the fuel system is disabled and the vehicle will
not start.
During normal operation, the security light will turn
off approximately ve seconds after the key is
turned to RUN.
If the engine stalls and the security light ashes,
wait about 10 minutes until the light stops
ashing before trying to restart the engine.
Remember to release the key from START as
soon as the engine starts.If the engine does not start after three tries, the
vehicle needs service.
If the engine is running and the security light comes
on, you will be able to restart the engine if you turn
the engine off. However, your Passlock
®system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock
®
at this time. You may also want to check the fuse.
