Your vehicle will have this feature if it is equipped with
the theft
-deterrent system. When unlocking either front
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 rear
power door locks provide a
lock only function as a
convenience feature. For
safety reasons, they will not
unlock the doors.
Automatic Door Locks
Close your doors and turn on the ignition. Every time
you move the shift lever out of PARK (P), all of 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
(If Equipped)
With the ignition in RUN, 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.

2-7 Leaving Your Vehicle
If you are leaving the vehicle, open the door, set the
locks from the inside, get out and close the door.
Remote Keyless Entry (RKE) System
If your vehicle has this
option, 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.
This system has a range of about 3 feet (1 m) up to
30 feet (9 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 to determine if battery replacement is
necessary. See the instructions that follow.

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.

If you're still having trouble, see your dealer or a
qualified technician for service.

2-8 Operation
When you press this symbol to unlock the driver's
door, the parking lamps on your vehicle will blink twice.
(You can program your vehicle so the parking lamps
will not flash. 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
(if equipped) and turn on the interior lamps at night.
When you press this symbol to lock the doors, the
parking lamps will blink once. (You can program your
vehicle so the parking lamps will not flash. For more
information, see ªLock/Unlock Confirmationº in the
Index.) This also arms the theft
-deterrent system (if
equipped).
Press this symbol to open the trunk. (The VALET
lockout button must be off for this feature to work.)
Press this button to open the fuel door. (The VALET
lockout button must be off for this feature to work.)
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.
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 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.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.

yellowblue
2-10 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 fuel door 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 horn
will sound and the exterior lamps will flash once. The
system should now operate properly. See your dealer for
service if your transmitter doesn't work properly.
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.

the retainer (center dial) on the compact spare tire
cover counterclockwise to remove it.
2. Place the trunk storage system on the center of the
trunk floor (the cut out portion of the storage system
should be facing the rear of the vehicle).

located in the carpeted area. This allows the unit to
unfold into place. Unfold the divider walls and move
them into the retention slots.

unsnap by hand.
5. Center the storage system access hole over the area
where the spare tire is secured by the retainer.

front of the divider walls and attach the hooks to the
holes on each side of the storage system.Once in place, the storage system can be moved
forward or rearward for convenience and easy access of
stored items.
The following steps explain how to remove the trunk
storage system for cleaning or in case you need to access
the spare tire. Follow all of these steps if the storage
system is in the closed position. Begin with Step 2 if the
system is already open.
1. Open the storage system by pulling up on the handle
located in the carpeted area. This allows the unit to
unfold into place. Unfold the divider walls and move
them into the retention slots.
2. Remove the rectangular access panel from the floor
of the storage system. The access panel should
unsnap by hand.
3. Center the storage system access hole over the area
where the spare tire is secured by the retainer.
