Engine Oil Life System

When to Change Engine Oil
This vehicle has a computer system that indicates when
to change the engine oil and filter. This is based on
engine revolutions and engine temperature, and not on
mileage. Based on driving conditions, the mileage at
which an oil change is indicated can vary considerably.
For the oil life system to work properly, the system
must be reset every time the oil is changed.
5-18
When the system has calculated that oil life has been
diminished, it indicates that an oil change is necessary.
A change engine oil light and a CHANGE ENGINE OIL
SOON message come on. Change the oil as soon as
possible within the next 600 miles (1 000 km). It is
possible that, if driving under the best conditions, the
oil life system might not indicate that an oil change is
necessary for over a year. However, the engine oil and
filter must be changed at least once a year and at this
time the system must be reset. Your dealer/retailer has
trained service people who will perform this work using
genuine parts and reset the system. It is also important
to check the oil regularly and keep it at the proper level.
If the system is ever reset accidentally, the oil must be
changed at 3,000 miles (5 000 km) since the last oil
change. Remember to reset the oil life system whenever
the oil is changed.
