Door Locks
CAUTION:
Unlocked doors can be dangerous.

Passengers -- especially children -- can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle won't open it. You increase the
chance of being thrown out of the vehicle in
a crash if the doors aren't locked. So, wear
safety belts properly and lock the doors
whenever you drive.

Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.

Outsiders can easily enter through an
unlocked door when you slow down or stop
your vehicle. Locking your doors can help
prevent this from happening.
There are several ways to lock and unlock your vehicle.
From the outside, use either of the keys or the remote
keyless entry transmitter.
With the theft
-deterrent system, you must unlock the
doors with the key or remote keyless entry transmitter to
avoid setting off the alarm.
Push down on the manual
lock lever to lock the
door from the inside.
To unlock the door,
pull up on the lever.

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 bottom part of the
power door lock switch
located on either front door
to lock all the doors at once.
Press the top of the switch
to unlock all the doors
at once.
The power door lock switches located on the rear doors
can also lock all the doors at once by pressing the
bottom part of them, but they cannot unlock the doors.
Automatic Door Locks
Your vehicle is programmed so that when the doors are
closed, the ignition is on and the shift lever is moved 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 lever or power lock switch. When
the door is closed again, it will not lock automatically.
Use the manual lever or power lock switch to lock the
door again. If you need to lock the doors before shifting
out of PARK (P), use the manual lever or power lock
switch 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 ªVehicle Programming and
Personalization Featuresº in the Index.

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
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.
(For more information,
see ªLock/Unlock
Confirmationº in the Index.)
The parking lamps will also not flash if they have been
turned on manually. Pressing this symbol again within
five seconds will unlock the other doors. Pressing this
symbol will disarm the theft
-deterrent system and turn
on the interior lamps at night.
When you press this symbol to lock the doors,
the parking lamps will flash once and the horn will
sound. The parking lamps will not flash, however, if the
manual parking lamps are left on. (You can 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 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 comes equipped with an
instant panic alarm. To use the alarm, press the horn
symbol with the ignition off. The horn will sound and
the exterior lamps 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 be used
to recall the memory settings for up to two drivers.
For more information, see ªMemory Seat, Mirrors
and Steering Wheelº in the Index.

2-11
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. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. 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.
All transmitters must be present when replacement or
additional transmitters are being programmed.
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.

2-13
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 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 this feature, see ªValet Lockout
Switchº in the Index.
