When the CHANGE ENGINE OIL SOON 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 SOON 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.
