Central Door Unlocking System
Your vehicle has a central door unlocking mode and a
theft
-deterrent system. When unlocking the driver's
door, you can unlock the other doors by holding the key
in the turned position for a few seconds or by quickly
turning the door key twice in the lock cylinder.
Power Door Locks
Press the power door lock
button to lock or unlock all
the doors at once. The
power door lock buttons
located on the rear doors
can lock all the doors at
once, but cannot unlock
the doors.
Automatic Door Locks
Your vehicle is equipped with a default mode, so that
every time your doors are closed, the ignition is on and
you move the shift lever out of PARK (P), all the doors
will lock. The doors will unlock every time you stop the
vehicle and move the shift lever back into PARK (P).
If someone needs to get out while your vehicle is not in
PARK (P), have that person use the manual or power
lock. When the door is closed again, it will not lock
automatically. Use the manual or power lock to lock the
door again. If you need to lock the doors before shifting
out of PARK (P), use the manual or power lock button
to lock the doors.
Programmable Automatic Door Locks
With the ignition in ON, the door locks can be
programmed through prompts displayed by the Driver
Information Center (DIC). These prompts allow the
driver to choose various lock settings. For programming
information, see ªMemory and Personalization
Featuresº in the Index.

Remote Keyless Entry System
With this feature, you can lock and unlock your doors
or unlock your trunk from about 3 feet (1 m) up to
30 feet (9 m) away using the remote keyless entry
transmitter supplied with your vehicle.
Your remote keyless entry transmitter operates on a
radio frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference received,
including interference that may cause undesired operation.
This device complies with RSS
-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this
device must accept any interference received, including
interference that may cause undesired operation of
the device.
Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.

2-8
The average range of this system is about 10 feet (3 m).
At times you may notice a decrease in range. This is
normal for any remote keyless entry transmitter. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:

Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.

Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.

Check to determine if battery replacement is
necessary. See the instructions that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.Operation
When you press this
symbol to unlock the
driver's door, the parking
lamps on your vehicle will
flash twice. (You can
program your vehicle so the
parking lamps will not
flash. They will also not
flash if the manual park
lamps are on.
For more information, see ªLock/Unlock Confirmationº
in the Index.) Pressing this symbol again within
five seconds will unlock the other doors. Pressing this
symbol will also disarm the theft
-deterrent system and
turn on the interior lamps at night.

2-9
When you press this symbol to lock the doors, the
parking lamps will flash once and the horn will sound.
The park lamps will not flash, however, if the manual
park lamps are left on. (You can also program your
vehicle so the parking lamps will not flash and the horn
will not sound. For more information, see ªLock/Unlock
Confirmationº in the Index.) This also arms the
theft
-deterrent system.
Press this symbol to open the trunk. (The VALET
lockout switch must be off for this feature to work.)
Your transmitter also comes equipped with an instant
panic alarm. To use the alarm, press this symbol. The
horn will sound and the exterior lights will flash for up
to 30 seconds. To stop the instant panic alarm, press the
symbol again or turn the ignition to ON.
The remote keyless entry transmitter can also be used to
recall the memory settings for up to two drivers. For
more information, see ªMemory Seat and Mirrorsº in
the Index.
Matching Transmitter(s) To Your Vehicle
Each remote keyless entry 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. Once your dealer has
coded the new transmitter, the lost transmitter will not
unlock your vehicle. Each vehicle can have only four
transmitters matched to it.
Since all vehicles come with only two transmitters. You
must check with your dealer for information on how to
obtain additional transmitters.

2-10
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two 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 the round end of the door key or a coin 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.

2-11
3. Replace the battery. Insert the new battery as the
instructions under the cover indicate.
4. Snap the transmitter back together tightly to be sure
no moisture can enter.
5. Resynchronize the transmitter. See
ªResynchronizationº following.
Resynchronization
Pressing the remote keyless entry transmitter buttons
numerous times (approximately 250 times) out of
the vehicle's operating range may cause the transmitter
not to work. Replacing the battery and pressing the
transmitter buttons out of range will also cause the
transmitter not to work. If only the instant alarm button
works, the transmitter needs to be resynchronized to the
receiver. Do this by pressing and holding both the lock
and unlock buttons on the transmitter for about eight
seconds. You must be within range of the vehicle.
Once the transmitter has been resynchronized, the locks
will cycle from lock to unlock. See your dealer for
service if your transmitter doesn't work properly.

2-12
Trunk
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 with the setting
on AUTO or ECON and the temperature
between 65 F (18 C) and 85 F (29 C).
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.
Trunk Lock Release
To use this feature, your
vehicle must be in PARK (P)
or NEUTRAL (N) and the
VALET lockout switch must
be off.
Press the trunk release button, located on the left side of
the instrument panel, to open the trunk.
You can also press the trunk button on the remote
keyless entry transmitter to access the trunk
compartment. To disable the use of this feature, see
ªValet Lockout Switchº in the Index.
