menu items can be displayed by pressing the
vehicle information button:
OIL LIFE REMAINING
If the vehicle has this display, it shows the
estimated oil life remaining. If you see 99% OIL
LIFE REMAINING on the display, that means that
99% of the current oil life remains.
When the oil life is depleted, the CHANGE ENGINE
OIL SOON message will appear on the display.
You should change the oil as soon as possible.
In addition to the engine oil life system monitoring
the oil life, additional maintenance is recommended
in the Maintenance Schedule in this manual. See
Scheduled Maintenance on page 465andEngine
Oil on page 365.
Remember, you must reset the OIL LIFE yourself
after each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed.

When the CHANGE ENGINE OIL SOON message
in the Driver Information Center (DIC) comes
on, it means that service is required for your
vehicle. Have your vehicle serviced as soon as
possible within the next 600 miles (1 000 km). It is
possible that, if you are driving under the best
conditions, the engine oil life system may
not indicate that vehicle service is necessary for
over a year. However, your 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, you must service your vehicle within
3,000 miles (5 000 km) since your last service.
Remember to reset the oil life system whenever
the oil is changed. SeeEngine Oil Life System on
page 368for information on the Engine Oil Life
System and resetting the system.
When the CHANGE ENGINE OIL SOON message
appears, certain services, checks, and inspections
are required. Required services are described
in the following for “MaintenanceI” and
“MaintenanceII.” Generally, it is recommended
that your rst service be MaintenanceI, your
second service be MaintenanceII, and that you
alternate MaintenanceIand MaintenanceII
thereafter. However, in some cases,
MaintenanceIImay be required more often.MaintenanceI— Use MaintenanceIif the
CHANGE ENGINE OIL SOON message comes on
within 10 months since the vehicle was purchased
or MaintenanceIIwas performed.
MaintenanceII— Use MaintenanceIIif the
previous service performed was MaintenanceI.
Always use MaintenanceIIwhenever 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.
