What Will You See After an Air Bag
Inates?
After the air bag inates, it quickly deates, so quickly that
some people may not even realize the air bag inated.
Some components of the air bag module will be hot for a
short time. These components include the steering wheel
hub for the driver’s frontal air bag and the instrument
panel for the right front passenger’s frontal air bag. For
vehicle’s with a driver’s side impact air bag, the side of
the seatback closest to the driver’s door will be hot. The
parts of the bag that come into contact with you may be
warm, but not too hot to touch. There will be some smoke
and dust coming from the vents in the deated air bags.
Air bag ination doesn’t prevent the driver from seeing or
being able to steer the vehicle, nor does it stop people
from leaving the vehicle.
{CAUTION:
When an air bag inates, there is dust in the
air. This dust could cause breathing problems
for people with a history of asthma or other
breathing trouble. To avoid this, everyone in
the vehicle should get out as soon as it is safe
to do so. If you have breathing problems but
can not get out of the vehicle after an air bag
inates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an air bag deployment, you
should seek medical attention.
Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the air
bags inate (if battery power is available). You can lock
the doors again and turn the interior lamps off by
using the door lock and interior lamp controls.

Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the air
bag systems. To purchase a service manual, seeService
Publications Ordering Information on page 7-12.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
air bag can still inate during improper
service. You can be injured if you are close to
an air bag when it inates. Avoid yellow
connectors. They are probably part of the air
bag system. Be sure to follow proper service
procedures, and make sure the person
performing work for you is qualied to do so.
The air bag systems do not need regular maintenance.
Restraint System Check
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)

At times you may notice a decrease in range. This is
normal for any remote keyless entry system. 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 or
resynchronization is necessary. See “Battery
Replacement” and “Resynchronization” under
Remote Keyless Entry System Operation on
page 2-4.
If you are still having trouble, see your dealer
or a qualied technician for service.
Remote Keyless Entry System
Operation
Using the remote keyless
entry transmitter, you can
lock and unlock your
doors or release your trunk
from about 3 feet (1 m)
up to 30 feet (9 m) away.
LOCK:Press the LOCK button to lock all the doors.
UNLOCK:Press the UNLOCK button once to unlock
the driver’s door and turn on the interior lamps. See
“Illumination on Remote Activation” later in this section for
more details. Pause for about one second, then press
UNLOCK again to unlock the passenger door.

Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about three 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.To replace the battery do the following:
1. Insert a at object like a coin into the slot on the
back of the transmitter. Gently pry apart the front
and back.
2. Gently pry the battery out of the transmitter. Do not
use a metal object.
3. Put the new battery into the transmitter as shown
on the transmitter. Use type CR2032 battery or
equivalent.
4. Put the two halves back together. Make sure the
halves are together tightly so water won’t get in.
5. Resynchronize and then test the transmitter.
Resynchronization
After you have changed the battery in your transmitter,
you will need to resynchronize the transmitter. To do this,
press the LOCK and UNLOCK buttons on the transmitter
at the same time and hold for about seven seconds or
until one horn chirp is heard.

Programmable Automatic Door
Locks
Programmable automatic power door locks are a
standard feature that is intended to provide enhanced
security and convenience by automatically locking
and unlocking doors.
Programmable Modes
Mode 1:No automatic door lock or unlock.
Mode 2:Automatic all-door lock when the transaxle is
shifted out of PARK (P); no automatic door unlock.
Mode 3:Automatic all-door lock when the transaxle is
shifted out of PARK (P); automatic unlock for the
driver’s door only when the transaxle is shifted into
PARK (P).
Mode 4:Automatic all-door lock when the transaxle is
shifted out of PARK (P); automatic all-door unlock
when the transaxle is shifted into PARK (P).Your vehicle was originally programmed to Mode 4.
The mode may have been changed since then.
To determine the current mode, or to change the
mode, seeVehicle Personalization on page 2-44.
Disconnecting the battery for up to a year will not
change the programmed mode of the programmable
automatic power door locks.
Lockout Protection
To protect you from locking your key in the vehicle, this
feature stops the power door locks from locking while
the key is in the ignition and a door is open.
If a power lock switch is pressed while a door is open
and the key is in the ignition, all of the doors will
lock and then the driver’s door will unlock. A chime will
sound continuously until all doors are closed.
Leaving Your Vehicle
If you are leaving the vehicle, take your keys, open your
door and set the locks from inside. Then get out and
close the door.

ACC (ACCESSORY):This is the position in which you
can operate your electrical accessories. With the key
in this position, the ignition and automatic transaxle will
unlock.
ON:This is the position to which the switch returns after
you start the engine and release the switch. The switch
stays in ON while the engine is running. But even when
the engine is not running, you can use ON to operate
your electrical accessories and to display some
instrument panel cluster messages and warning lights.
START:This position starts the engine. When the
engine starts, release the key. The ignition switch will
return to ON for normal driving.
While the engine is not running, ACC and ON allow you
to operate your electrical accessories, such as the radio.
A warning chime will sound if you open the driver’s door
while the ignition is in OFF or ACC and the key is in
the ignition.
Retained Accessory Power (RAP)
With Retained Accessory Power (RAP), your power
windows, audio system and sunroof (option) will
continue to work for up to 10 minutes after the ignition is
turned to OFF and none of the doors is opened.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position — that’s a
safety feature. To restart when you’re already moving,
use NEUTRAL (N) only.
Notice:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.
Starting Your 3400 V6 Engine
1. With your foot off the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as
your engine warms up.
Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.
2. If the engine doesn’t start in 10 seconds, push the
accelerator pedal about one-quarter of the way down
while you turn the key to START. Do this until the
engine starts. As soon as it does, let go of the key.
2-18

3. If your engine still won’t start (or starts but then
stops), it could be ooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
oor and holding it there as you hold the key in
START for a maximum of 15 seconds. This clears
the extra gasoline from the engine. If the engine
still won’t start or starts briey but then stops again,
repeat Step 1 or 2, depending on temperature.
When the engine starts, release the key and the
accelerator pedal.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly.Starting Your 3800 Series II V6 Engine
1. With your foot off the accelerator pedal, turn
your ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as
your engine gets warm.
Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.
2. If it doesn’t start within 10 seconds, hold your key
in START for about 10 seconds at a time until your
engine starts. Wait about 15 seconds between
each try.

Keep the original transmitter for use in other vehicles as
well as for future HomeLink®programming. It is also
recommended that upon the sale of the vehicle,
the programmed HomeLink
®buttons should be erased
for security purposes. Refer to “Erasing HomeLink®
Buttons” or, for assistance, contact HomeLink®on the
internet at: www.homelink.com or by calling
1-800-355-3515.
Be sure that people and objects are clear of the garage
door or gate operator you are programming. When
programming a garage door, it is advised to park outside
of the garage.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency.
Your vehicle’s engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Press and hold down the two outside buttons,
releasing only when the indicator light begins to
ash, after 20 seconds. Do not hold down the
buttons for longer than 30 seconds and do not
repeat this step to program a second and/or third
transmitter to the remaining two HomeLink
®buttons.
2. Position the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the HomeLink
®
buttons while keeping the indicator light in view.3. Simultaneously press and hold both the desired
button on HomeLink
®and the hand-held transmitter
button. Do not release the buttons until Step 4
has been completed.
Some entry gates and garage door openers may
require you to substitute Step 3 with the procedure
noted in “Gate Operator and Canadian
Programming” later in this section.
4. The indicator light will ash slowly at rst and then
rapidly after HomeLink
®successfully receives the
frequency signal from the hand-held transmitter.
Release both buttons.
5. Press and hold the newly-trained HomeLink
®button
and observe the indicator light.
If the indicator light stays on constantly, programming
is complete and your device should activate when the
HomeLink
®button is pressed and released.
To program the remaining two HomeLink®buttons,
begin with Step 2 under “Programming HomeLink®.”
Do not repeat Step 1 as this will erase all of the
programmed channels.
If the indicator light blinks rapidly for two seconds
and then turns to a constant light, continue with
Steps 6 through 8 following to complete the
programming of a rolling-code equipped device
(most commonly, a garage door opener).
