Your vehicle is equipped with an engine oil change
indicator system. The "Oil Change Due" message will
flash in the EVIC display for approximately 10 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 cycle the ignition to the ON/RUN position. To
turn off the message temporarily, press and release the
MENU button. To reset the oil change indicator system
(after performing the scheduled maintenance), perform
the following procedure:

1. Without pressing the brake pedal, push the ENGINE
START/STOP button and cycle the ignition to the ON/
RUN position (Do not start the engine.)

2. Fully depress the accelerator pedal, slowly, three times
within 10 seconds.

3. Without pressing the brake pedal, push the ENGINE
START/STOP button once to return the ignition to the
OFF/LOCK position.

NOTE: If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure.
