Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. You do not want the system to
inate while someone is working on your vehicle.
Your dealer and the service manual have information
about servicing your vehicle and the airbag system.
To purchase a service manual, seeService Publications
Ordering Information on page 7-14.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
airbag can still inate during improper service.
You can be injured if you are close to an
airbag when it inates. Avoid yellow
connectors. They are probably part of the
airbag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualied to do so.
The airbag system does not need regular maintenance.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front or
sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, front end or side sheet
metal or height, they may keep the airbag system
from working properly. Also, the airbag system may
not work properly if you relocate any of the airbag
sensors. If you have any questions about this,
you should contact Customer Assistance before you
modify your vehicle. The phone numbers and
addresses for Customer Assistance are in Step Two
of the Customer Satisfaction Procedure in this
manual. SeeCustomer Satisfaction Procedure on
page 7-2.

Remote Keyless Entry System
If the vehicle has the keyless entry system, it 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 interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to

Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter will not
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.
The Driver Information Center (DIC) will display a KEY
FOB # BATTERY LOW message when the transmitter
battery is low.
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 in the remote keyless entry
transmitter do the following:
1. Insert a thin coin in the slot between the covers
of the transmitter housing. Gently pry the
transmitter apart.
2. Remove and replace the battery with a three-volt
CR2032 or equivalent battery.
3. Align the covers and snap them together.
4. Check the operation of the transmitter.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Content Theft-Deterrent
Your vehicle may be equipped with a content
theft-deterrent alarm system.
The security light is
located on the instrument
panel cluster.Here’s how to operate the system:
1. Open the door.
2. Lock the door with the power door lock switch or
the remote keyless entry transmitter. The security
light should ash.
3. Close all doors. The security light should turn off
after approximately 30 seconds. The alarm is not
armed until the security light turns off.
If a locked door is opened without the key or the remote
keyless entry transmitter, the alarm will go off. The
headlamps and parking lamps will ash for two minutes,
and the horn will sound for 30 seconds, then will turn
off to save the battery power.
Remember, the theft-deterrent system won’t activate if
you lock the doors with a key or use the manual
door lock. It activates only if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should also remember that
you can start your vehicle with the correct ignition key if
the alarm has been set off.

Ignition Positions
Use the key to turn the ignition switch to four different
positions.
A (LOCK):This position locks the ignition and
transmission. It is a theft-deterrent feature. You will only
be able to remove the key when the ignition is turned
to LOCK.
Notice:If your key seems stuck in LOCK and you
cannot turn it, be sure you are using the correct key;
if so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break the
key or the ignition switch. If none of these works,
then your vehicle needs service.B (ACCESSORY):This position lets you use things
like the radio and the windshield wipers when the
engine is off.
Notice:Lengthy operation of features such as the
radio in the accessory ignition position may drain the
battery and prevent your vehicle from starting. Do not
operate your vehicle in the accessory ignition
position for a long period of time.
C (RUN):This is the position for driving.
D (START):This position starts the engine.
Retained Accessory Power (RAP)
Your vehicle is equipped with a Retained Accessory
Power (RAP) feature which will allow certain features of
your vehicle to continue to work up to 20 minutes
after the ignition key is turned to LOCK.
Your radio, power windows, sunroof (option) and
overhead console will work when the ignition key is in
RUN or ACCESSORY. Once the key is turned from
RUN to LOCK, these features will continue to work for
up to 20 minutes or until a door is opened.

Starting the Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as
your engine gets warm.
Your vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the
engine and protects the electrical system. If the
ignition key is turned to the START position,
and then released when the engine begins cranking,the engine will continue cranking until the vehicle
starts or until it exceeds the maximum cranking time
allowed, approximately 15 seconds to prevent
cranking motor damage. To prevent gear damage,
this system also prevents cranking if the engine
is already running. The engine cranking can
be stopped by turning the ignition switch to the
ACCESSORY or LOCK position.
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 does not start within 10 seconds, push the
accelerator pedal all the way to the oor, while you
hold the ignition key in START. When the engine
starts, let go of the key and let up on the accelerator
pedal. Wait about 15 seconds between each try.

Engine Coolant Heater
Your vehicle may have an engine coolant heater. In
very cold weather, 0°F (−18°C) or colder, the engine
coolant heater can help. You will get easier starting and
better fuel economy during engine warm-up. Usually,
the coolant heater should be plugged in a minimum
of four hours prior to starting your vehicle. At
temperatures above 32°F (0°C), use of the coolant
heater is not required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is located on the driver’s side of the engine
compartment, behind the battery.
3. Plug it into a normal, grounded 110-Volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.

Universal Home Remote System
Operation
Do not use the Universal Home Remote with any
garage door opener that does not have the stop and
reverse feature. This includes any garage door opener
model manufactured before April 1, 1982. If you
have a newer garage door opener with rolling codes,
please be sure to follow Steps 6 through 8 to complete
the programming of your Universal Home Remote
Transmitter.
Read the instructions completely before attempting to
program the Universal Home Remote. Because of
the steps involved, it may be helpful to have another
person available to assist you in the programming steps.
Keep the original hand-held transmitter for use in
other vehicles as well as for future Universal Home
Remote programming. It is also recommended that upon
the sale of the vehicle, the programmed Universal
Home Remote buttons should be erased for security
purposes. See “Erasing Universal Home Remote
Buttons” later in this section or, for assistance, see
Customer Assistance Offices on page 7-4.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 signal.
Programming Universal Home Remote
Follow these steps to program up to three channels:
1. Press and hold down the two outside Universal
Home Remote buttons, releasing only when the
Universal Home Remote 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
hand-held transmitter to the remaining two Universal
Home Remote buttons.
2. Position the end of your hand-held transmitter
about 1 to 3 inches (3 to 8 cm) away from the
Universal Home Remote buttons while keeping the
indicator light in view.
