1-30 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.
Safety Belt Pretensioners
Your vehicle has safety belt pretensioners. You'll find
them on the buckle end of the safety belts for the
driver and right front passenger. They help the
safety belts reduce a person's forward movement in
a moderate to severe crash in which the front of the
vehicle hits something.
Pretensioners work only once. If they activate in a crash,
you'll need to get new ones, and probably other new
parts for your safety belt system. See ªReplacing
Restraint System Parts After a Crashº in the Index.
Rear Seat Passengers
It's very important for rear seat passengers to buckle up!
Accident statistics show that unbelted people in the rear
seat are hurt more often in crashes than those who are
wearing safety belts.
Rear passengers who aren't safety belted can be thrown
out of the vehicle in a crash. And they can strike others
in the vehicle who are wearing safety belts.

2-11
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
The average range of this system is about 10 feet (3 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 the following:

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.Operation
(Lock): When you
press this symbol to lock the
doors, the parking lamps
will flash once and the horn
will sound once. This arms
the theft
-deterrent system.
The parking lamps will not flash, however, if the manual
parking lamps are left on. Remote confirmation is not
operational if a door is open.
You can program your vehicle so the parking lamps
will not flash and the horn will not sound. For more
information, see ªVehicle Programming and
Personalization Featuresº in the Index.
(Unlock): When you press this button to unlock
the driver's door, the parking lamps on your vehicle
will flash twice. The parking lamps will not flash if they
have been turned on manually. Remote confirmation is
not operational if a door is open.

2-13 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 an object like a coin to pry open the transmitter.

2-14
2. Once the transmitter is separated, use an object like
a pencil to remove the old battery. Do not use a
metal object.
3. 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. Press any button on the remote keyless entry
transmitter to resynchronize the transmitter.
6. Check the operation of the transmitter.
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
65F (18C) and 85F (29C). 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.

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.

2-52 Illuminated Entry
The illuminated entry system turns on the courtesy
lamps and the backlighting to the door switches and to
the exterior lamp control when a door is opened or if
you press the remote keyless entry transmitter unlock
button. If activated due to the transmitter, the lighting
will remain active for about 40 seconds. Since the
illuminated entry system uses the light sensor, it must be
dark outside in order for the courtesy lamps to turn on.
The courtesy lamps turn off approximately 25 seconds
after the last door is closed. They will dim to off if the
ignition key is placed in ON, or immediately deactivate
if the power locks are activated.
Parade Dimming
This feature prohibits dimming of the digital displays
and backlighting during daylight hours when the key is
in the ignition and the headlamps are on. This feature
operates with the light sensor for the Twilight Sentinel
and is fully automatic. When the light sensor reads
darkness outside and the parking lamps are active,
the digital displays can be adjusted by turning the
instrument panel brightness knob counterclockwise
to dim and clockwise to brighten lighting.
Reading Lamps
The front reading lamps are located in the overhead
console. These lamps and the interior courtesy lamps
come on when a door is opened and it is dark outside.
The rear reading lamps will not come on when a front
door is opened.
The rear courtesy lamps are located on the rear headliner
above the rear seat outboard positions. When a rear door
is opened, both the front and rear reading lamps come
on with the courtesy lamps.
Press the button near each lamp to turn it on and off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Battery Load Management
The battery load management feature is designed to
monitor the vehicle's electrical load and determine
when the battery is in a heavy discharge condition.
During times of high electrical loading, the engine
may idle at a higher revolutions per minute (rpm)
setting than normal to make sure the battery charges.
High electrical loads may occur when several of the
following are on: headlamps, high beams, fog lamps,
rear window defogger, the climate control fan at high
speeds, heated seats and engine cooling fans.

2-77
CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to ON.
If the light doesn't come on then, have it fixed so it
will be ready to warn you if there is a problem.
Charging System Light
When you turn the key to
ON or START, this light
will come on briefly to
show that the generator and
battery charging systems are
working properly.
If this light stays on, you need service and you should
take your vehicle to the dealer at once. To save your
battery until you get there, turn off all accessories.

3-30 Radio Personalization with Home and Away
Feature (If Equipped)
If DRIVER 1 (HOME or AWAY) PRESETS or
DRIVER 2 (HOME or AWAY) PRESETS appears in
the display when the radio is first turned on, your
vehicle is equipped with this feature.
This feature allows the driver to return to the last used
audio source (radio, cassette or CD) using their remote
keyless entry transmitter. This feature can also store
and recall AM and FM presets, volume, tone and the
last selected radio station. The number on the back of
each transmitter (1 or 2) corresponds to driver 1 or 2.
If transmitter 1 is used to enter the vehicle, the last
used audio source and/or settings set by driver 1 will be
recalled. If transmitter 2 is used to enter the vehicle, the
last used audio source and/or settings set by driver 2 will
be recalled. The settings can also be recalled by pressing
the MEMORY seat buttons 1 or 2 located on the
driver's door.Your radio can store home and away presets. Home and
away presets allow you to use one set of preset radio
settings in the area where you live, and another set when
you go out of town. That way, you will not need to
reprogram your presets every time you travel. With the
radio off and the clock displayed, use fast forward and
reverse to select home or away presets. To select the
away presets, press and hold FF for five seconds until
you hear a beep. The next time the radio comes on, the
away presets will be active. To select the home presets,
press and hold RW or REV for five seconds until you
hear a beep. The next time the radio comes on, the home
presets will be active.
When battery power is removed and later applied, you
will not have to reset your home radio presets because
the radio remembers them. However, you will have to
reset your away radio presets.
