2-73 Malfunction Indicator Lamp
(Check Engine 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 CHECK ENGINE light comes on 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 CHECK ENGINE 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.

2-75
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.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 in order to
help your vehicle pass an inspection:
Your vehicle will not pass this inspection if the 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.

2-77 Cruise Light
The CRUISE light comes
on whenever you set your
cruise control. See ªCruise
Controlº in the Index.
This light will come on for a few seconds when you turn
the ignition key to RUN to let you know it is working.
Fuel Gage
United States CanadaWhen the ignition is on, your fuel gage tells you about
how much fuel you have left.
When you have less than 3.0 gallons (11.3 L) of
fuel remaining, the DIC message LOW FUEL will
be displayed and a chime will sound. You need to get
more fuel right away.
Here are four things that some owners ask about.
None of these show a problem with your fuel gage:

At the service station, the gas pump shuts off
before the gage reads full.

It takes a little more or less fuel to fill up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took
a little more or less than half the tank's capacity to
fill the tank.

The gage moves a little when you turn a corner
or speed up.

The tank is not necessarily empty when the gage
reads empty. There is a reserve of about 1.5 gallons
(5.6 L) in the tank. You should still get more fuel
as soon as possible.

Driver Information Center (DIC)
The Driver Information Center (DIC) displays
information in either English or metric. When the
system is on or off, push the ON/OFF button down
for three seconds to change the display between English
and metric. This will also change the digital screen for
the climate control system between English and metric.The DIC has different display modes which can be
accessed by pressing the four buttons on the DIC.
These buttons are labeled ON/OFF, SELECT right
arrow, SELECT down arrow and RESET. The button
functions are detailed in the following.
Turn on the system by pressing the ON/OFF button
once. When you turn on the ignition, the DIC will be in
the mode last displayed when the engine was turned off.
Keep in mind that this also applies to the OFF mode.
To turn off messages on the DIC (except LOW OIL
PRESSURE, LOW BRAKE FLUID, PARK BRAKE
SET, STARTING DISABLED and the HOT...STOP
ENGINE warning), press the RESET button.
Pressing the SELECT right arrow button will allow
you to access the following modes, DATE/ET, FUEL,
ECON, OIL and GAGE. While in any of these modes,
warning messages can interrupt and take over the
display until you acknowledge the message, or the
condition causing the problem goes away.

2-80 Fuel
Press SELECT down arrow while in the FUEL mode
to see how much fuel has been used and the fuel
range functions.
Fuel Used
While in the FUEL USED function the display will
show a reading such as:
FUEL USED: 10.4 GAL or FUEL USED: 39.4 L
To learn how much fuel will be used from a specific
starting point, first enter the FUEL USED mode to
display FUEL USED, then press and hold the
RESET button for three seconds.
Don't confuse fuel used with the amount of fuel in
your tank.
Fuel Range
The FUEL RANGE mode calculates the remaining
distance you can drive without refueling. It's based
on fuel economy and the fuel remaining in the tank.
The display will show a reading such as:
FUEL RANGE: 235 MI or FUEL RANGE: 378 KMIf the range is less than 50 miles (80 km), the display
will read LOW FUEL RANGE.
The fuel economy data used to determine fuel range is
an average of recent driving conditions. As your driving
conditions change, this data is gradually updated.
Fuel range cannot be reset.
Fuel Economy
Pressing the SELECT down arrow while in the ECON
mode displays average fuel economy and instantaneous fuel
economy calculated for your specific driving conditions.
Average fuel economy will be shown in a reading such as:
25.2 AVG MI/GAL or 9.3 AVG L/100 KM
Instantaneous fuel economy will be shown in a reading
such as:
28 INST MI/GAL or 8.4 INST L/100 KM
The average fuel economy is viewed as a long
-term
approximation of your overall driving conditions.
If you press and hold RESET for three seconds in
this mode while you're driving, the system will begin
figuring average fuel economy from that point in time.
Instantaneous fuel economy cannot be reset.
