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 SERVICE ENGINE SOON
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.

2-65
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.
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 a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly.
See ªFilling Your Tankº in the Index. 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 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.

2-72
CHECK OIL LEVEL - 36: For correct operation of the
low oil sensing system, your vehicle should be on a level
surface. A false CHECK OIL LEVEL message may
appear if the vehicle is parked on grades. The oil level
sensing system does not check for actual oil level if the
engine has been off for a short period of time, and the oil
level is never sensed while the engine is running. If the
CHECK OIL LEVEL message appears and your vehicle
has been parked on level ground with the engine off for
at least 30 minutes, the oil level should be checked by
observing the oil dipstick. Prior to checking the oil level,
be sure the engine has been off for five minutes and your
vehicle is on a level surface. Then check the dipstick and
add oil if necessary. See ªEngine Oilº in the Index.
CHECK WASHER FLUID

engine must be running and the transaxle not in
PARK (P) for this message to display. A chime will
also sound when the vehicle's speed is greater than
5 mph (8 km/h).DRIVER DOOR AJAR
- 140: This message
will display when the vehicle is being shifted out of
PARK (P) with the engine running to signal that the
driver's door is open or ajar. A chime will also sound
when the vehicle's speed is greater than 5 mph (8 km/h).
ENGINE COOLANT HOT, IDLE ENGINE
- 44:
This message will appear when the engine coolant
temperature is over 248
F (126
C). To avoid added
strain on a hot engine, turn off the climate control
system. Stop and allow your vehicle to idle until it cools
down or the message is removed. If it does not cool
down, turn off the engine and have it serviced before
driving it again. Severe engine damage can result from
an overheated engine. See ªEngine Overheatingº in
the Index.
ENGINE HOT
- A/C OFF - 16: This message displays
when the engine coolant becomes hotter than the normal
operating temperature. To avoid added strain on a hot
engine, the air conditioning compressor is automatically
turned off so that air conditioned air is not delivered.
If the coolant temperature returns to normal, you must
select AC to return to a normal A/C compressor
operation. If this message continues to appear,
have the system repaired as soon as possible to avoid
compressor damage.

The outside temperature sensor is located near the front
grille. The sensor can be affected by road or engine heat
during idling, slow driving or when the engine is first
started after a short trip. In order to ensure proper
automatic climate control operation, the outside air
temperature display may not update as quickly as
expected. This is to allow the air surrounding the outside
temperature sensor to be as close to the actual outside
conditions as possible. This is determined by how much
time has elapsed since the vehicle has been turned off
and by vehicle speed.
Mode Button
Press the MODE button to deliver air through the floor,
middle or windshield outlets. The system will stay in the
selected mode until the MODE button is pressed again.
Press the up or down arrow to cycle through the
available modes.
Automatic Operation
When the system is set for automatic operation, sensors
will control the air delivery mode. Air will come from
the floor, middle or windshield outlets. The fan speed
will vary as the system maintains the selected
temperature setting.Be careful not to put anything over the solar sensor
located in the middle of the instrument panel near the
windshield. This sensor is used by the automatic system
to regulate temperature.
To find your comfort zone, start with the 75
F (24
C)
setting and allow about 30 minutes for the system to
regulate. Turn the TEMP/AUTO knob to adjust the
temperature if necessary. If you choose 60
F (16
C),
the system will remain at that maximum cooling setting
and will not regulate fan speed. If you choose the
temperature of 90
F (32
C), the system will remain at
that maximum heating setting and will not regulate fan
speed. Choosing either maximum setting will not cause
the system to heat or cool any faster.
With the automatic setting, the air conditioning
compressor automatically cycles when needed to cool
the air. In cold weather, when the system senses the
need for heat, the airflow will be directed out the floor
outlets. As the interior temperature approaches a desired
setting, the blower speed will decrease. To maintain
interior comfort, the airflow may move to the instrument
panel air outlets and floor outlets (bi
-level mode). On
bright sunny days in cold weather, the airflow may come
out of the air conditioning outlets (AC mode) to
maintain comfort and prevent stuffiness.
