Yellow Telltale Indicator Lights
Engine Check/Malfunction Indicator Light (MIL)
Yellow TelltaleLight What It Means
Engine Check/Malfunction Indicator Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a part of an Onboard Diagnostic Sys-
tem called OBD II that monitors engine and automatic transmission control systems. The light
will illuminate when the ignition is in the ON position before engine start. If the bulb does not
come on when turning the key from OFF to ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap, poor quality fuel, etc., may illuminate
the light after engine start. The vehicle should be serviced if the light stays on through several
typical driving styles. In most situations, the vehicle will drive normally and will not require
towing.
When the engine is running, the MIL may flash to alert serious conditions that could lead to
immediate loss of power or severe catalytic converter damage. The vehicle should be serviced
as soon as possible if this occurs.

630 MAINTAINING YOUR VEHICLE

Normally, the OBD II system will be ready. The OBD II
system maynotbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated test, which
you can use prior to going to the test station. To check if
your vehicle’s OBD II system is ready, you must do the
following:
1. Cycle the ignition switch to the ON position, but do not crank or start the engine.
NOTE: If you crank or start the engine, you will have to
start this test over.
2. As soon as you cycle the ignition switch to the ON position, you will see the “Malfunction Indicator Light
(MIL)” symbol come on as part of a normal bulb
check. 3. Approximately 15 seconds later, one of two things will
happen:
• The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF
the ignition or start the engine. This means that your
vehicle’s OBD II system is not readyand you should
not proceed to the I/M station.
• The MIL will not flash at all and will remain fully
illuminated until you place the ignition in the off
position or start the engine. This means that your
vehicle’s OBD II system is readyand you can proceed
to the I/M station.
If your OBD II system is not ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your

NOTE: Lens fogging can occur under certain atmo-
spheric conditions. This will usually clear as atmospheric
conditions change to allow the condensation to change
back into a vapor. Turning the lamps on will usually
accelerate the clearing process.7

High Intensity Discharge Headlamps (HID) —
If Equipped
The headlamps are a type of high voltage discharge tube.
High voltage can remain in the circuit even with the
headlamp switch off and the key removed.Because of
this, you should not attempt to service a headlamp bulb
yourself. If a headlamp bulb fails, take your vehicle to
an authorized dealer for service.
WARNING!
A transient high voltage occurs at the bulb sockets of
High Intensity Discharge (HID) headlamps when the
headlamp switch is turned ON. It may cause serious
electrical shock or electrocution if not serviced prop-
erly. See your authorized dealer for service.
NOTE:
On vehicles equipped with High Intensity Dis-
charge (HID) headlamps, when the headlamps are turned on, there is a blue hue to the lamps. This diminishes and
becomes more white after approximately 10 seconds, as the
system charges.
Halogen Headlamps — If Equipped
1. Open the hood.
2. Turn the low or high beam bulb one–quarter turn
counterclockwise to remove from housing.
3. Disconnect the electrical connector and replace the bulb.
CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the
bulb comes in contact with any oily surface, clean the
bulb with rubbing alcohol.

Front Turn Signal
1. Open the hood.
2. Turn the turn signal bulb one–quarter turn counter-clockwise to remove from housing.
3. Disconnect the electrical connector and replace the bulb.
CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the
bulb comes in contact with any oily surface, clean the
bulb with rubbing alcohol.
Front Fog Lamps
1. Reach through the cutout in the splash shield anddisconnect the wiring harness from the fog lamp
connector.
2. Firmly grasp the bulb by the two latches and squeeze them together to unlock the bulb from the back of the
front fog lamp housing.
3. Pull the bulb straight out from the keyed opening in the housing.
CAUTION!
•Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If
the bulb comes in contact with any oily surface,
clean the bulb with rubbing alcohol.
