2-78 Malfunction Indicator Lamp (Service
Engine Soon Light)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (On
-Board
Diagnostics
-Second Generation) and is intended to assure
that emissions are at acceptable levels for the life of the
vehicle, helping to produce a cleaner environment. The
SERVICE ENGINE SOON light comes on and a chime
will sound to indicate that there is a problem and service is
required. Malfunctions often will be indicated by the
system before any problem is apparent. This may prevent
more serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
NOTICE:
Modifications made to the engine, transaxle,
exhaust or fuel system of your vehicle or the
replacement of the original tires with other than
those of the same Tire Performance Criteria
(TPC) can affect your vehicle's emission controls
and may cause the ªSERVICE ENGINE SOONº
light to come on. Modifications to these systems
could lead to costly repairs not covered by your
warranty. This may also result in a failure to pass
a required Emission Inspection/Maintenance test.

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.

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:

Reducing vehicle speed.

Avoiding hard accelerations.

Avoiding steep uphill grades.

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 ªIf
the Light Is On Steadyº 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 ªIf the Light
Is On Steadyº 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 ªFilling Your Tankº in the Index. 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.

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
ªFuelº in the Index). 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.
Oil Pressure Light
This light tells you if there
could be a problem with
your engine oil pressure.The oil pressure light can come on briefly when you turn
your key to RUN. It goes off once you turn the key to
START. That's just a check to be sure the light works. This
is normal and doesn't show a problem. If it doesn't come
on and then go off, be sure to have it fixed so it will be
there to warn you if something goes wrong.
When this light comes on and stays on, and a chime
sounds, it means oil isn't going through your engine
properly. You could be low on oil, or you might have
some other oil problem. See your dealer for service.
CAUTION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil problems
can be costly and is not covered by your warranty.

2-81 Service Vehicle Soon Light
This light will come on if
you have certain
non
-emission related
vehicle problems.
For example, if the entire electrical system fails to send
and receive messages from the vehicle's components, the
SERVICE VEHICLE SOON warning light comes on.
These problems may not be obvious and may affect
vehicle performance or durability. Consult a qualified
dealership for necessary repairs to maintain top vehicle
performance. The light will come on briefly when your
ignition is turned on to show that it is working properly.
Cruise Light
The CRUISE light comes
on when you set your cruise
control. See ªCruise
Controlº in the Index.
Fuel Gage
Your fuel gage shows about
how much fuel is in your
tank. It works only when
the ignition is on.
When the indicator moves to the edge of the low fuel
warning band, the low fuel light will turn on and a
chime will sound. You still have a little fuel left, but you
need to get more fuel right away.
A concern owners have had about the fuel gage is that it
takes more (or less) gas to fill up than the gage
indicated. For example, the gage may have indicated
half full, but it took more (or less) than half of the tank's
capacity to fill it. This situation is normal and indicates
nothing wrong with the fuel gage.

Head-Up Display (HUD)
(If Equipped)
CAUTION:
If the HUD image is too bright, or too high in
your field of view, it may take you more time to
see things you need to see when it's dark outside.
Be sure to keep the HUD image dim and placed
low in your field of view.
If your vehicle is equipped with the Head-Up Display
(HUD), you can see some of the driver information that
appears on your instrument cluster.
The information may be displayed in English or metric
units and appears as a reflection in the windshield. The
HUD consists of the following information:

Speedometer Reading

Turn Signal Indicators

High
-Beam Headlamp Indicator

CHECK GAGES Message
The HUD shows these images when they are lighted on
the instrument panel cluster.
Be sure to continue scanning your displays, controls and
driving environment just as you would in a vehicle
without HUD. If you never look at your instrument
panel, you may not see something important, such as a
warning light.

Comfort Controls
This section tells you how to operate your comfort
controls. Your comfort control system uses
ozone
-friendly R-134a refrigerant.
With these systems, you can control the heating, cooling
and ventilation in your vehicle. Your vehicle also has a
flow
-through ventilation system described later in
this section.
Personal Choice Comfort Controls
(If Equipped)
This feature allows two different drivers to store and
recall their own climate control settings for temperature,
air delivery mode, fan and passenger climate control
(on/off) status. The Personal Choice settings recalled are
determined by the transmitter used to enter the vehicle.
After the UNLOCK button of a remote keyless entry
transmitter is pressed, and the ignition is in RUN, the
climate control will adjust to the last settings of the
identified driver. The settings can also be changed by
pressing one of the MEMORY buttons (1 or 2) located
on the driver's door, until you hear two beeps. When
adjustments are made, the new settings are automatically
saved for the driver.
Dual Automatic ComforTemp
Climate Control
Your vehicle has the dual automatic comfortemp climate
control system. The following information tells you how
it works.
You will hear a beep each time a button is pushed and a
small light on the button will indicate which buttons are
active. The lights are on all buttons except TEMP, FAN
and AIR FLOW. The display will show fan speed,
comfort level setting and airflow direction for a few
seconds whenever any button, except for the rear defog,
is pushed, and then it will display the outside
temperature. The outside temperature reading is most
accurate when the vehicle is moving.
During stops, when driving slow, or when the engine is
first started after a short trip, the outside temperature
reading can be affected by road or engine heat. Also,
starting the engine within a short time after the vehicle
has been running will affect the reading. To ensure
proper automatic climate control operation, the
outside temperature display may not update as quickly
as expected.
