noFUSE
If the vehicle diagnostic system determines
that the Ignition Off Draw (IOD) fuse is improp-
erly installed, or damaged, a "noFUSE" mes-
sage will display in the odometer display area.
For further information on fuses and fuse loca-
tions refer to "Fuses" in "Maintaining Your Ve-
hicle".
CHAngE OIL Message
Your vehicle is equipped with an engine oil
change indicator system. The "CHANgE OIL"
message will flash in the instrument cluster
odometer for approximately 12 seconds after a
single chime has sounded to indicate the next
scheduled oil change interval. The engine oil
change indicator system is duty-cycle based,
which means the engine oil change interval
may fluctuate dependent upon your personal
driving style.
Unless reset, this message will continue to
display each time you turn the ignition switch to
the ON/RUN position. To turn off the message
temporarily, press and release the Trip Odom-
eter button on the instrument cluster. To reset
152
the oil change indicator system (after perform-
ing the scheduled maintenance), refer to the
following procedure:
1. Turn the ignition switch to the ON/RUN
position (Do not start the engine).
2. Fully depress the accelerator pedal
slowly three times within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK
position.
NOTE:
If the indicator message illuminates when
you start the vehicle, the oil change indica-
tor system did not reset. If necessary repeat
this procedure.
26. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL)
is a part of an Onboard Diagnostic
System called OBD II that monitors
engine and automatic transmission
control systems. The light will illumi-
nate 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.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also
could affect fuel economy and drivability. If the
MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Im-
mediate service is required.
