NOTICE:
If you damage the covering for the driver's or
the right front passenger's air bag, or the air bag
covering on the driver's, right front passenger's
or rear seatback, the bag may not work properly.
You may have to replace the air bag module
in the steering wheel, both the air bag module
and the instrument panel for the right front
passenger's air bag, or both the air bag module
and seatback for the side impact air bag. Do not
open or break the air bag coverings.
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,
see ªService and Owner Publicationsº in the Index.
CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured if you are close to an air bag when
it inflates. Avoid yellow connectors. They are
probably part of the air bag systems. Be sure to
follow proper service procedures, and make sure
the person performing work for you is qualified
to do so.
The air bag systems do not need regular maintenance.

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 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.

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.

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.

2-17
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
Even if you park in a lot where someone will be
watching your vehicle, it's still best to lock it up and
take your keys. But what if you have to leave your
ignition key?

If possible, park in a busy, well
-lit area.

Put your valuables in a storage area, like your
trunk or glove box. Be sure to close and lock the
storage area.

Close all windows.

Move the valet lockout switch to ON.

Leave only the valet key.

Take all other keys and the Remote Keyless Entry
transmitter with you.
Theft-Deterrent System
If the ignition is off and
any door is open, the
SECURITY light will flash,
reminding you to activate
the system.
The light will also flash if the battery has been
disconnected and reconnected.
To arm the system, do the following:
1. Open the door.
2. Lock the door using the power door lock or the
remote keyless entry transmitter. The SECURITY
light should come on and stay on.
3. Close all the doors. The SECURITY light should go
off within about 30 seconds.
When the theft
-deterrent system activates, the horn will
sound and the lamps will flash for about 30 seconds
when the door or trunk is opened without the key or the
remote keyless entry transmitter.

2-24
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:
Don't try to shift to PARK (P) if your vehicle is
moving. If you do, you could damage the
transaxle. Shift to PARK (P) only when your
vehicle is stopped.
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.

2-36
Shifting Out of PARK (P)
Your vehicle has an automatic transaxle shift lock
control system. You have to fully apply your regular
brakes before you can shift from PARK (P) when the
ignition key is in ON. See ªAutomatic Transaxle
Operationº in the Index.
If you cannot shift out of PARK (P), ease pressure on
the shift lever
-- push the shift lever all the way into
PARK (P) as you maintain brake application. Then
move the shift lever into the gear you want. If you ever
hold the brake pedal down, but still can't shift out of
PARK (P), try the following:
1. Turn the ignition to ACCESSORY.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear
you want.
5. Have the vehicle fixed as soon as you can.
Shift Lock Release
This vehicle is equipped with an electric shift lock
release system. The shift lock release is designed to do
the following:

Prevent the ignition key from being removed unless
the shift lever is in PARK (P), and

Prevent movement of the console shift lever (DTS
only) out of PARK (P) unless the ignition is in a
position other than OFF. The shift lock release is
always functional except in the case of a dead battery
or low voltage (less than 9 V) battery.
If your vehicle has a dead battery or a battery with low
voltage, there is a procedure that will allow you to
override the shift lock release.

2-37
The following procedure allows the ignition to be turned
to OFF and for key removal in case of a dead or low
voltage battery.
1. Verify that the shift lever
is in PARK (P).
2. Locate the override
access slot underneath
the steering column
below the lock cylinder.
3. Remove the override access slot cap.
4. Insert a screwdriver into the access slot, press in
and hold.
5. Turn the ignition to OFF.
6. Remove the screwdriver from the slot.
7. Remove the key from the ignition.
8. Replace the override access slot cap.The following procedure applies only to vehicles with
the console shift lever and is used to shift the transaxle
out of PARK (P) (if the vehicle needs to be towed,
for example) in case of a dead or low voltage battery.
The console shift lock
release is located on the
front of the center console.
To access the shift lock release, do the following:
1. Verify that the shift lever is in PARK (P).
2. Pull up the rubber mat located on the front of the
center console.
3. Remove the shift lock release hole cover by prying it
open with a coin or small diameter screwdriver.

Light Sensor
The light sensor for the DRL and the Twilight Sentinel
is located in the center of the front defogger grille.
If you cover the sensor, it will read ªdarkº and the
lamps or the HEADLAMPS SUGGESTED message
will be on whenever the ignition is on.
Exterior Lighting Battery Saver
If the headlamp or manual parking lamp control
has been left on, the exterior lamps will turn off
approximately 10 minutes after the ignition is turned
to OFF. This protects draining the battery in case you
have accidentally left the headlamps or parking lamps
on. If you need to purposely leave the lamps on for
more than 10 minutes with the ignition in OFF or
ACCESSORY, turn the manual control knob off and
then back on. To delay the lamps from turning off,
see ªTwilight Sentinelº in the Index.
If the headlamp switch is turned on after the ignition key
is moved to either OFF or ACCESSORY, the lamps will
not time out.
