Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.
NOTICE:
When replacing the battery, use care not to touch
any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.
1. Use a flat thin object to pry open the transmitter.
2. Once the transmitter is separated, use a pencil or
similar object to remove the old battery. Do not use
a metal object.

no moisture can enter.

transmitter to resynchronize the transmitter.
6. Check the operation of the transmitter.

Trunk Lid
CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't 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 ªComfort Controlsº
in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.

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 and transmission. 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 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.

Theft-Deterrent System
The security light is located
on the instrument panel
cluster.
If the ignition is off and a door is open, the security light
will flash, reminding you to arm the theft
-deterrent
system.
To arm the system, do the following:
1. Open the door.
2. Lock the door using the remote keyless entry
transmitter or the power door lock switch. The
security light should come on and stay on.
3. Close all the doors. The security light should go off
within approximately 30 seconds.
If a door or a trunk is opened without a key or a remote
keyless entry transmitter, the horn will sound and the
lamps will flash for up to 30 seconds.The theft
-deterrent system won't arm if you lock the
doors with a key or use the manual door lock. It
activates only if you use the remote keyless entry
transmitter.
To avoid activating the alarm by accident do the
following:

The vehicle should be locked with the door key or
the manual door lock after the doors are closed if
you don't want to arm the theft
-deterrent system.

Always unlock a door with a key or use the remote
keyless entry transmitter. Pressing the unlock button
on the remote keyless entry transmitter disables the
theft
-deterrent system. Unlocking a door any other
way will activate the alarm when a door or the trunk
is opened.
If you activate the alarm by accident, unlock the driver's
door with your key. You can also turn off the alarm by
using the unlock button on the remote keyless entry
transmitter, or by starting the vehicle with a valid key.
