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 a combination of factors which include engine revolutions, engine temperature, and miles driven.
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.
When the system has calculated that oil life has been diminished, it indicates
that an oil change is necessary. A
%CHANGE DIC message comes on. Change the oil as soon as possible within the next
1 000 km (600 mi). It is possible that, if driving under the best conditions, the
oil life system may indicate that an oil change is not necessary for up to a year.
The engine oil and filter must be changed at least once a year and, at this time,
the system must be reset. Your dealer has trained service people who will perform
this work and reset the system. It is also important to check the oil regularly
over the course of an oil drain interval and keep it at the proper level.
If the system is ever reset accidentally, the oil must be changed at 5 000 km (3,000 mi) since the last oil change.
Remember to reset the oil life system whenever the oil is changed.
How to Reset the Engine Oil Life System
Reset the system whenever the engine oil is changed so that the system can calculate the next engine oil change. Always reset the engine oil life to 100% after every oil change. It will not reset itself. To reset the system:

%CHANGE DIC message comes
back on when the vehicle is started, the engine oil life system has not reset. Repeat
