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 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 ENGINE OIL SOON
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 might indicate that an oil change is not necessary for up to two years. The engine oil and filter must be changed at least once every two years
and, at this time, the system must be reset. 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. To reset the system:
1. Use the SELECT knob to select OIL LIFE on the Driver Information Center menu.
2. Press SELECT to start the OIL LIFE reset procedure.
3. The Driver Information Center menu will display "Are you sure that you want to reset?" Use SELECT to choose YES to reset oil life or NO to exit
and return to the previous menu.
4. If YES is selected, the Driver Information Center menu will display RESET OIL LIFE for a short time and then 100% OIL LIFE will be displayed
when OIL LIFE is successfully reset. If the CHANGE ENGINE OIL SOON message comes back on when the vehicle is started, the engine oil life
system has not reset. Repeat the procedure.
