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 Odometer button on the instrument cluster.
To reset the oil change indicator system
(after performing the scheduled maintenance) refer to the following procedure.
1. Turn the ignition switch to the ON 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 indicator system did not reset. If necessary repeat this procedure.
