When the CHANGE ENGINE OIL message appears,
certain services, checks, and inspections are required.
Required services are described in the following for
“Maintenance I” and “Maintenance II.” Generally,
it is recommended that your first service be
Maintenance I, your second service be Maintenance II,
and that you alternate Maintenance I and Maintenance II
thereafter. However, in some cases, Maintenance II
may be required more often.
Maintenance I — Use Maintenance I if the CHANGE
ENGINE OIL message comes on within 10 months since
the vehicle was purchased or Maintenance II was
performed.
Maintenance II — Use Maintenance II if the previous
service performed was Maintenance I. Always use
Maintenance II whenever the message comes on
10 months or more since the last service or if the
message has not come on at all for one year.
