Oil Change Required

Your vehicle is equipped with an
engine oil change indicator system.
The “Oil Change Required”
message will display in the
instrument cluster display for five 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 the ignition is placed in the ON/RUN
position. To turn off the message temporarily, push
and release the OK or arrow buttons. To reset the
oil change indicator system (after performing the
scheduled maintenance), refer to the following
procedure.
