passenger door lock switch.

Door Ajar Reminder
If one of the doors of your vehicle is not closed properly,
the ignition is on and you shift from PARK (P) or
NEUTRAL (N), you will hear a chime. Also, the Door
Ajar light on the instrument panel will come on and stay
on until the doors are closed and completely latched.
Rear Door Security Locks
Your vehicle is equipped
with rear door security
locks that help prevent
passengers from opening
the rear doors of your
vehicle from the inside.
The switch is located on the inside of the rear door.
To use the security locks:
1. Move the switch up.
2. Close the door.
3. Do the same thing on the other rear door.

2-6
The rear doors of your vehicle cannot be opened from
the inside when this feature is in use. If you want to
open 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 don't cancel the security lock feature, adults or
older children who ride in the rear won't be able to open
the rear door from the inside. You should let adults and
older children know how these security locks work, and
how to cancel the locks.
To cancel the rear door lock:
1. Unlock the door from the inside and open it from the
outside.
2. Move the switch down.
3. Do the same for the other rear door.
The rear doors will now work normally.Anti-Lockout Protection (If Equipped)
Anti-lockout protection is a feature with power door
locks, intended to provide enhanced security and
convenience. This feature prevents a driver who has left
the keys in the ignition from locking the doors, using
the power door locks while any door is open.
When trying to lock the doors with the key in the
ignition and any door is opened, the doors will lock
and then unlock.
To override this feature, when the key is in the ignition
and any door is open, hold the power door lock switch
down for three seconds.
This feature cannot guarantee that you will never be
locked out of your vehicle. If you don't leave the keys in
the ignition, or if you use the manual door lock, or if you
use the remote keyless entry transmitter (if available),
you could still lock your keys inside your vehicle.
Always remember to take your keys with you.
Leaving Your Vehicle
If you are leaving your vehicle, open your door and set
the locks from the inside, then get out and close the door.

2-10 Resynchronization
Your 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.
To synchronize 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 five seconds. In this time, the
doors should lock and unlock once. This confirms
the resynchronization. If the doors do not lock and
unlock, see your dealer for service.
Trunk
To unlock the trunk from the outside, insert the key and
turn the trunk lock cylinder.
When closing the trunk, close from the center to ensure
it fully latches.
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 VENT. 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.

Understanding Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise if you ever get it.
FM Stereo
FM stereo will give you the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to come and go.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until it is too late. Your hearing can adapt to higher
volumes of sound. Sound that seems normal can be loud
and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to a safe
sound level before your hearing adapts to it.To help avoid hearing loss or damage:

Adjust the volume control to the lowest setting.

Increase volume slowly until you hear comfortably
and clearly.
NOTICE:
Before you add any sound equipment to your
vehicle
-- like a tape player, CB radio, mobile
telephone or two
-way radio -- be sure you can
add what you want. If you can, it's very
important to do it properly. Added sound
equipment may interfere with the operation of
your vehicle's engine, Delphi Delco Electronics
radio or other systems, and even damage them.
Your vehicle's systems may interfere with the
operation of sound equipment that has been
added improperly.
So, before adding sound equipment, check with
your dealer and be sure to check Federal rules
covering mobile radio and telephone units.

clothing, a small shovel, a flashlight, a red cloth and a
couple of reflective warning triangles. And, if you will
be driving under severe conditions, include a small bag
of sand, a piece of old carpet or a couple of burlap bags
to help provide traction. Be sure you properly secure
these items in your vehicle.
