typemust be done at the times or mileages specified to
assure the continued proper functioning of the emission

equipped vehicles, ªOil Change Requiredº will be dis-
played in the EVIC and a single chime will sound,
indicating that an oil change is necessary.
Based on engine operation condition the oil change
indicator message will illuminate, this means that service
is required for your vehicle. Have your vehicle serviced
as soon as possible, within the next 500 miles (805 km).
NOTE:
²The oil change indicator message will not monitor the
time since the last oil change. Change your vehicles oil
if it has been 6 months since your last oil change even

nated.
