Center (DIC), service is required for
the vehicle. SeeDIC Warnings
and Messages on page 3-37. Have
the vehicle serviced as soon as
possible within the next 600 miles
(1 000 km). It is possible that, if
driving under the best conditions,
the engine oil life system may
not indicate that vehicle service is
necessary for over a year. However,
the engine oil and lter must be
changed at least once a year and
at this time the system must be
reset. Your dealer/retailer has
trained service technicians who will
perform this work using genuine
parts and reset the system.If the engine oil life system is ever
reset accidentally, service the
vehicle within 3,000 miles
(5 000 km) since the last service.
Remember to reset the oil life
system whenever the oil is changed.
SeeEngine Oil Life System on
page 5-15for information on
the Engine Oil Life System and
resetting the system.

appears, certain services, checks,
and inspections are required.

the following for “MaintenanceI”
and “MaintenanceII.” Generally, it is
recommended that the rst service
be MaintenanceI, the second
service be MaintenanceII, and then

MaintenanceIIthereafter. However,
in some cases, MaintenanceII
may be required more often.MaintenanceI—Use
