Malfunction Indicator Lamp
Check Engine Light
Your vehicle has 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 make sure 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 can 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, the emission
controls might not work as well, your vehicle’s
fuel economy might not be as good, and the
engine might not run as smoothly. This
could lead to costly repairs that might not be
covered by your warranty.
Notice:Modications made to the engine,
transmission, 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 can cause
this light to come on. Modications to these
systems could lead to costly repairs not
covered by your warranty. This could also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 253.

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 does not
come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and could damage the emission
control system on your vehicle. Diagnosis and
service might be required.
Light On Steady— An emission control
system malfunction has been detected on your
vehicle. Diagnosis and service might be
required.
If the Light is Flashing
The following can prevent more serious damage
to your vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.If the light continues to ash, when it is safe to do
so, stop the vehicle. Find a safe place to park
the vehicle. Turn the key off, wait at least
10 seconds, and restart the engine. If the light
remains on steady, see “If the Light Is On Steady”
following. If the light is still ashing, follow the
previous steps and see your dealer/retailer
for service as soon as possible.
If the Light Is On Steady
You might 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. SeeFilling the Tank on page 258.
The diagnostic system can determine if the
fuel cap has been left off or improperly installed. A
loose or missing fuel cap allows fuel to evaporate
into the atmosphere. A few driving trips with
the cap properly installed should turn the light off.

Oil Pressure Light
If your vehicle has low
engine oil pressure, this
light will stay on after
you start your engine, or
come on and you will
hear a chime when you
are driving.

enough oil. The engine could be low on oil,
or could have some other oil problem. Have it
xed immediately.
This light will come on briey when you turn on
the ignition as a check to show you it is working. If
it does not come on with the ignition on, you
may have a problem with the bulb. Have it xed
right away.{CAUTION:
Do not 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:Lack of proper engine oil maintenance
may damage the engine. The repairs would

Fuel Gage
Your fuel gage tells you about how much fuel you
have left, when the ignition is on. When the
indicator nears empty, a LOW FUEL message will
appear on the Driver Information Center (DIC).
SeeDIC Warnings and Messages on page 182for
more information. You still have a little fuel left,
but you should get more soon. The arrow on
the fuel gage points to side of the vehicle with the
fuel door.Here are four things that some owners ask about.
These are normal and do not indicate 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 indicator moves a little when you turn a
corner or speed up.
The gage goes back to empty when you turn
off the ignition.
