Enhanced Traction System
Warning Light
If your vehicle is equipped with the Enhanced Traction
System (ETS), this warning light should come on
brie¯y as you start the engine. If the warning light
doesn't come on, then have it ®xed so it will be ready to
warn you if there's a problem.
If the warning light stays on, or comes on when you're
driving, there may be a problem with your Enhanced
Traction System and your vehicle may need service.
When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.The Enhanced Traction System warning light may come
on for the following reasons:
·If you turn the system off by moving the shift lever
to FIRST (1) or SECOND (2), the warning light will
come on and stay on. To turn the system back
on, move the shift lever back to a position other than
FIRST (1) or SECOND (2). The warning light
should go off. See
Enhanced Traction System (ETS)
on page 4-8for more information.
·The warning light will come on when you set your
parking brake with the engine running, and it will stay
on if your parking brake doesn't release fully. If the
transaxle shift lever is in any position other than
FIRST (1) or SECOND (2) and the warning light
stays on after your parking brake is fully released, it
means there's a problem with the system.
·If the traction control system is affected by an
engine-related problem, the system will turn off and
the warning light will come on.
·If the vehicle is driven on an extremely rough road,
the warning light may come on momentarily but will
go off again when the vehicle leaves the rough
surface.
If the Enhanced Traction System warning light comes
on and stays on for an extended period of time when the
transaxle shift lever is in any position other than
FIRST (1) or SECOND (2), your vehicle needs service. United States

Low Coolant Warning Light
This light comes on brie¯y
when you turn your
ignition on.
If this light comes on and stays on, the coolant level in
your vehicle is low. If the light is on along with an
overheat warning, you may have a serious overheating
problem. See
Engine Coolant Temperature Gage on
page 3-29.
Notice:Damage to your engine from neglected
coolant problems can be costly and is not covered
by your warranty.
See
Engine Coolant on page 5-22for information on
what to do. Your vehicle should be serviced as soon as
possible.
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:Modi®cations made to the engine,
transaxle, exhaust, intake 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 this light to come on.
Modi®cations 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 FlashingÐ A mis®re condition has been
detected. A mis®re increases vehicle emissions and
may damage the emission control system on your
vehicle. Diagnosis and service may be required.
·Light On SteadyÐ An emission control system
malfunction has been detected on your vehicle.
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 ¯ashing and remains on steady, see ªIf
the Light Is On Steadyº following.
If the light continues to ¯ash, 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 ¯ashing, follow the
previous steps, and see your dealer for service as soon
as possible.

Oil Pressure Light
If you have a low engine
oil pressure problem, this
light will stay on after
you start your engine, or
come on when you
are driving. This indicates
that your engine is not
receiving enough oil.
The engine could be low on oil, or could have some
other oil problem. Have it ®xed immediately.
The oil light could also come on in three other situations:
·When the ignition is on but the engine is not
running, the light will come on as a test to show you
it is working, but the light will go out when you
turn the ignition to START. If it doesn't come on with
the ignition on, you may have a problem with the
fuse or bulb. Have it ®xed right away.
·If you're idling at a stop sign, the light may blink on
and then off.
·If you make a hard stop, the light may come on for
a moment. This is normal.
{CAUTION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches ®re. 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.

Service Vehicle Soon Light
This light will come on
brie¯y when you turn on
the ignition.
It will stay on or come on if it detects a problem on the
vehicle. If this happens, see your dealer's service
department as soon as possible.
Fuel Gage
Your fuel gage tells you about how much fuel you have
left. When the indicator nears empty, the CHECK
GAGES light will come on. You still have about
1.5 gallons (5.7 L) of fuel left, but you should get more
soon. See
Check Gages Warning Light on page 3-34earlier in this section for more information.
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 ®ll 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
®ll the tank.
·The gage moves a little when you turn a corner or
speed up.
·The gage doesn't go back to empty when you turn
off the ignition.
For your fuel tank capacity, see
Capacities and
Speci®cations on page 5-85.
