and ventilation for your vehicle. remaining air
to the floor outlets. Some air may be
directed toward the windshield. Cooler air is directed to
the upper outlets and warmer air to the floor outlets.
(Floor): This mode directs most of the air to
the floor outlets with some air directed toward the
outboard outlets (for the side windows) and a little air
directed to the windshield.
The mode knob can also be used to select defog or
defrost mode. Information on defogging and defrosting,
see "Defogging and Defrosting" later in this section.

A/C (Air Conditioning): Press this button to turn the
air-conditioning system on or
off. When A/C is pressed,
an indicator light above the button will come on to let
you know that
A/C is active. The instrument brightness
control may have to be adjusted to
the highest setting
during the daytime in order to see the indicator light.
On hot days, open the windows to let hot inside
air escape; then close them. This helps to reduce the
time it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down
on hot days:
1. Select the MAX recirculation mode.
2. Select A/C.
3. Select the coolest temperature.
4. Select the highest fan speed.
Using these settings together for long periods of time
may cause the air inside your vehicle to become too dry.
To prevent this from happening, after the air in your
vehicle has cooled, change the mode from MAX
to another mode such as bi-level.
The air-conditioning system removes moisture from the
air,
so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning
off the engine. This is normal.
Defogging and Defrosting
There are two modes to clear fog from your windshield.
Use the floor/defog mode
to clear the windows of fog
or moisture and warm the passengers. Use the defrost
mode to remove fog or frost from the windshield
more quickly.
Turn the mode knob to select the defog or defrost mode.
,2 (Floor/Defog): This mode directs the air equally
between the windshield and the floor outlets. When you
select this mode, the system turns on the
air-conditioning compressor unless the outside
temperature is at or below freezing.
9 FRONT (Defrost): Pressing FRONT directs most
of the air to the windshield and the side window
outlets, with some air directed to the floor outlets. In this
mode, the system will automatically run the
air-conditioning compressor, unless the outside
temperature is at or below freezing.

If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.
If the air bag reai.---less light
s 1s 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
RUN. 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
The
charging system
light will come on briefly
when you turn on the
ignition as a check to
show you it’s working.
Then it will go out.
If it stays on, or comes on while you are driving, you
may have a problem with the electrical charging system.
It could indicate that you have a loose drive belt or
another electrical problem. Have
it checked right away.
Driving while this light is on could drain your battery.
If you must drive a short distance with the light on,
be certain to turn
off all your accessories, such as the
radio and air conditioner.

This light should come on, as a check to show you it is
working, when the ignition is on and the engine is
not running. If the light doesn’t come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing - A misfire condition has been
detected. A misfire increases vehicle emissions
and may damage the emission control system on
your vehicle. Dealer or qualified service center
diagnosis and service may be required.
0 Light On Steady - An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis
and service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
0 Avoiding hard accelerations.
Avoiding steep uphill grades.
0 If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible. If
the light stops flashing and remains on steady,
see “If the Light
Is On Steady” following.
If the light continues to flash, when
it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key
off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see
“If the Light Is
On Steady” following. If the light is still flashing, follow the
previous steps, and drive the vehicle
to your dealer or
qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See Filling
Your Tank on page 5-7. The
diagnostic system can determine
if the fuel cap has
been left
off or improperly installed. A loose or missing
fuel cap will allow fuel
to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light
off.
Did you just drive through a deep puddle of water?
If
so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light
off.
3-33

Are you low on fuel?
As your engine starts to run out of fuel, your engine
may not run as efficiently as designed since small
amounts of air are sucked into the fuel line causing
misfire. The system can detect this. Adding fuel should
correct this condition. Make sure to install the fuel
cap properly. See filling
Your Tank on page 5-7. It will
take a few driving trips to turn the light
off.
Have you recently changed brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel. See
Gasoline Ocfane on page
5-5. Poor fuel quality will
cause your engine not to run as efficiently as designed.
You may notice this as stalling after start-up, stalling
when you put the vehicle into gear, misfiring, hesitation
on acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the
light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn
off,
have your dealer or qualified service center check
the vehicle. Your dealer has the proper test equipment
and diagnostic tools to fix any mechanical or electrical
problems that may have developed.
Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection
if the SERVICE
ENGINE SOON or CHECK ENGINE light is on or not
working properly.
Your vehicle will not pass this inspection
if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen
if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving.
If you have done this and your vehicle
still does not pass the inspection for lack of
OBD
system readiness, see your dealer or qualified service
center to prepare the vehicle for inspection.

CD/PLAY: Press this button to play a CD when
listening to the radio.
EJECT: Press this button to stop a CD when it is
playing or to remove a CD when it is not playing.
The EJECT button will work with the radio
off.
Compact Disc Messages
E (Error): If this message and a number appears on
the radio display or
if the disc comes out, it could be for
one of the following reasons:
You’re driving on a very rough road. When the road
becomes smoother, the disc should play.
It’s very hot. When the temperature returns to
normal, the disc should play.
The disc is dirty, scratched, wet or upside down.
The air is very humid. If so, wait about an hour and
try again.
If the CD is not playing correctly, for any other reason,
try a known good
CD.
If any error occurs repeatedly or if an error can’t be
corrected, contact your dealer.
If your radio displays an
error number, write it down and provide it to your
dealer when reporting the problem.
Theft-Deterrent Feature
THEFTLOCK@ is designed to discourage theft of your
radio. It works by using a secret code to disable all radio
functions whenever battery power is interrupted.
The THEFTLOCK feature for the radio may be used or
ignored.
If ignored, the system plays normally and
the radio is not protected by the feature. If THEFTLOCK
is activated, your radio will not operate
if stolen.
When THEFTLOCK is activated, the radio will display
LOC to indicate a locked condition anytime battery
power is removed. If your battery loses power for any
reason, you must unlock the radio with the secret
code before it will operate.
Activating the Theft-Deterrent Feature
The instructions which follow explain how to enter
your secret code to activate the THEFTLOCK system.
Read through all nine steps before starting the
procedure.
If you allow more than 15 seconds to elapse between
any steps, the radio automatically reverts to time
and you must start the procedure over at Step 4.
1. Write down any three or four-digit number from 000
to 1999 and keep it in a safe place separate from
the vehicle.

Cassettes are subject to wear and the sound quality
may degrade over time. Always make sure the cassette
tape is in good condition before you have your tape
player serviced.
Care of Your CDs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust.
If the surface of a disc is soiled, dampen
a clean, soft cloth in a mild, neutral detergent solution
and clean it, wiping from the center to the edge.
Be sure never to touch the side without writing when
handling discs. Pick up discs by grasping the outer
edges or the edge of the hole and the outer edge.
Care of Your CD Player
The use of CD lens cleaner discs is not advised, due to
the risk
of contaminating the lens of the CD optics
with lubricants internal to the CD mechanism.
Backglass Antenna
The AM-FM antenna is integrated with the rear window
defogger, located in the rear window. Be sure that
the inside surface of the rear window is not scratched
and that the lines on the glass are not damaged.
If the inside surface is damaged, it could interfere with
radio reception. Also, for proper radio reception,
the antenna connector at the top-center of the rear
window needs to be properly attached to the post on
the glass.
Notice; Do not try to clear frost or other material
from the inside of the rear window with a razor blade
or anything else that
is sharp. This may damage
the rear defogger grid and affect your radio’s ability
to pick up stations clearly. The repairs wouldn’t
be covered by your warranty.
Because this antenna is built into your rear window,
there is a reduced risk of damage caused by car washes
and vandals.
If you choose
to add a cellular telephone to your
vehicle, and the antenna needs to be attached
to the
glass, be sure that you do not damage the grid lines for
the AM-FM antenna. There is enough space between
the lines
to attach a cellular telephone antenna
without interfering with radio reception
Do not apply aftermarket glass tinting to the back glass.
The metallic film in some tinting materials will interfere
with or distort the incoming radio reception. Care
must be taken when cleaning the rear window because
it breaks in the resistive material heating element
and will adversely affect radio and defogger
performance. See your dealer for details.
