2-59 Speedometer and Odometer
The speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h). The
odometer shows how far your vehicle has been driven,
in either miles (used in the United States) or kilometers
(used in Canada).
You may wonder what happens if a vehicle has to have a
new odometer installed. The new one may read the
correct mileage. This is because your vehicle's computer
has stored the mileage in memory.Trip OdometerBy pressing this button,
you can tell how far
you've traveled since you
last set the trip odometer
back to zero.
For information on resetting this button, see ªDIC
Controls and Displaysº in the Index.
English/Metric Display
Press the SKIP INFO button until ENGLISH/METRIC
RESET displays and then press NO INFO RESET to select.
Note: Other readings such as temperature, fuel and trip
odometer also go back and forth between English
and metric.

Vehicle Speed Limiter
This feature prevents your vehicle from exceeding
speeds that the tires are not rated for. When this
happens, the engine's fuel supply is shut off. When the
vehicle speed slows, the fuel supply will come on again.
Tachometer
This gage indicates the
engine speed in revolutions
per minute (RPM).
NOTICE:
Do not operate the engine with the tachometer in
the red area or engine damage may occur.
Engine Speed Limiter
This feature prevents the engine from operating at
too many revolutions per minute (RPM). When the
engine's RPM are critically high, the fuel supply to the
engine is shut off. When the engine speed slows, the
fuel supply will come on again. This helps prevent
damage to the engine.

2-66 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 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.
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.
Oil Pressure Light
This light tells you if there
could be a problem with
your engine oil pressure.
The light goes on when you turn your key to RUN or
START. It goes off once you start your engine. That's a
check to be sure the light works. If it doesn't come on,
be sure to have it fixed so it will be there to warn you if
something goes wrong.
When the light comes on and stays on, it means that oil isn't
flowing through your engine properly. You could be low on
oil and you might have some other system problem.
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.
Fuel Gage
The fuel gage shows
approximately how much
fuel is in the tank. It works
only when the ignition is
in RUN.Here are a few concerns some owners have had about
the fuel gage. All of these situations are normal and do
not indicate that anything is wrong with the fuel gage.

At the gas station the gas pump shuts off before the
gage reads F.

It takes more (or less) gas to fill the tank than the
gage said. For example, the gage read half a tank, but
it took more (or less) than the tank's remaining
capacity to fill it.

The gage may change when you turn, stop or
speed up.
Fuel Data Display
Everything you need to know about the fuel economy
and how far you can travel with your vehicle's
remaining fuel is displayed. Fuel data can be obtained
by pressing the SKIP INFO button. See ªDIC Controls
and Displaysº later in this section.
