To replace the battery in the transmitter:
1. Use a coin or similar object to separate the bottom
half from the top half of the transmitter.
2. Remove the battery and replace it with the new
one. Make sure the positive side of the battery
faces down. For battery replacement, use a
three-volt battery, type CR2032, or equivalent.
3. Read the instructions inside the case.
4. Put the two halves back together. Make sure the
cover is on tightly, so water will not get in.
5. Check the operation of the transmitter with your
vehicle. If the transmitter does not work, try
resynchronizing the transmitter with the receiver.Resynchronization
Your remote keyless entry system is equipped with a
security system that prevents anyone from recording and
playing back your signal. The transmitter does not
send the same signal twice to the receiver. The receiver
will not respond to a signal that has been sent to it
more than once.
Normally, the transmitter and receiver resynchronize
automatically. However, under certain circumstances,
manual resynchronization may be required.
To resynchronize your transmitter and receiver, follow
these directions:
1. Stand close to your vehicle.
2. Press and hold the LOCK and UNLOCK buttons on
the transmitter at the same time.
3. Hold the buttons for at least 10 seconds. During this
time, the doors should lock and unlock once. This
conrms the resynchronization. If the doors do
not lock and unlock, see your dealer for service.

Power Door Locks
If your vehicle has this
feature, you can lock or
unlock all the doors
on your vehicle from the
driver’s or front
passenger’s door
lock switch.
Press the lower portion of the switch to lock the doors.
Press the upper portion of the switch to unlock the doors.
The locking lever on each rear door works only
that door’s lock. It will not lock or unlock all of the
doors — that is a safety feature.
Rear Door Security Locks
If your vehicle is a
four-door model, it is
equipped with rear door
security locks that
help prevent passengers
from opening the rear
doors on your vehicle from
the inside.
Using the Rear Door Security Lock
1. Use a key to move the lock all the way up.
2. Close the door.
3. Do the same thing to the other rear door lock.
The rear doors on your vehicle cannot be opened from
the inside when this feature is in use.
2-9

Opening a Rear Door When the
Security Lock is On
1. Unlock the door from the inside.
2. Then open the door from the outside.
If you do not cancel the security lock feature, adults or
older children who ride in the rear will not be able to
open the rear door from the inside. You should let adults
and older children know how to cancel the locks.
Canceling the Rear Door Security Lock
1. Unlock the door from the inside and open the
door from the outside.
2. Use a key to move the lock all the way down.
3. Do the same for the other rear door.
The rear door lock will now work normally.
Lockout Protection
If your vehicle is equipped with remote keyless entry,
you have lockout protection. This feature stops the
power door locks from locking when the key is in the
ignition and the door is open.
If the power door lock switch is pressed when a door is
open and the key is in the ignition, all the doors will
lock and the driver’s door will unlock.
Trunk
To unlock the trunk from the outside, insert the key and
turn the trunk lock cylinder or use the remote keyless
entry transmitter if your vehicle has one.
When closing the trunk, it is recommended that you use
two hands and from the center to ensure it latches fully.
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot 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 and select the
control setting that will force outside air
into your vehicle. See Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-29.

the ignition is in OFF or ACCESSORY, the parking
brake is engaged, or the vehicle speed is less than
2 mph (3 km/h).
Emergency Trunk Release Handle
Notice:Using the emergency trunk release handle
as a tie-down or anchor point when securing
items in the trunk may damage it. Use the
emergency trunk release handle only to help you
open the trunk lid.
There is a glow-in-the-dark emergency trunk release
handle located on the inside of the trunk lid of your
vehicle. This handle will glow following exposure to light.
Pull the release handle up to open the trunk from
the inside.

Theft-Deterrent Systems
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.
Content Theft-Deterrent
Arming the System
With the ignition off, press the LOCK button on the
remote keyless entry transmitter to arm the system
immediately after all doors and the trunk are closed. If
the LOCK button is pressed again within ve seconds,
the horn will chirp to conrm that the system has
been armed.
Once the system is armed, the THEFT SYSTEM light
on your instrument panel will ash and remain ashing.
This conrms the system is armed and monitoring
the doors and trunk. If the light is on solid, the system is
not properly activated due to either a door or the
trunk being ajar.
If you do not want to arm the system, lock the car with
the lock levers on the doors or with the power door
lock switch.
Disarming the System
If the system is armed, press the UNLOCK button on
the transmitter to disarm the system. The THEFT
SYSTEM light will stop ashing.
If the system is armed, turning the key to START will
also disarm the system.
If the system is armed and the trunk is opened using
the trunk release button on the transmitter, the system
will temporarily disarm itself and re-arm when the
trunk has been closed. This allows the customer to exit
the vehicle, lock the doors using the transmitter, and
open the trunk using the transmitter without having
to disarm and subsequently re-arm the system.
How the System Alarm is Activated
If the system is armed, opening any door or trunk, or
using a wrong key to start the vehicle will cause a
pre-alarm chirp for 10 seconds and then a full alarm of
horn and headlights for two minutes.
If an alarm event has nished and all doors and trunk
are closed, the content theft security system will
re-arm itself.
2-14

How to Turn Off the System Alarm
If the system alarm is active, it can be deactivated by:
Pressing the LOCK or panic button on the
transmitter to turn off the alarm. The system will
re-arm if all doors and the trunk are later closed.
Pressing the UNLOCK or trunk button on the
transmitter to turn off the alarm and disarm
the system.
Putting the key in the ignition and turning it to
START to turn off the alarm and disarm the system.
How to Detect a Tamper Condition
If you hear three horn chirps when you press the
UNLOCK, LOCK or trunk release buttons on your
transmitter, the content theft security system alarm was
triggered while you were away.
Your dealer can change the settings to disable the
headlamp ash and horn chirp features. Your dealer can
also change the settings to allow the horn to chirp
twice on the rst press of the UNLOCK button. See your
dealer for more information.
Passlock®

turned to the RUN ignition position following an

If the engine stalls and the THEFT SYSTEM light
ashes, wait 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 is running and the THEFT SYSTEM light
comes on, you will be able to restart the engine if
