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 timing, engine load, and engine
temperature, and not on mileage. Based on driving conditions, the mileage at which an engine 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 miles). 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. 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 5 000 km (3,000 miles) 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
The Engine Oil Life System calculates when to change the engine oil and filter based on vehicle use. Whenever the oil is changed, reset the system so
it can calculate when the next oil change is required. If a situation occurs where the oil is changed prior to a CHANGE ENGINE OIL SOON message
being turned on, reset the system.
To reset the CHANGE ENGINE OIL SOON message:
1. Turn the ignition key to ON/RUN with the engine off.
2. Fully press and release the accelerator pedal slowly three times within five seconds.
3. Turn the key to LOCK/OFF.
If the message comes back on when the vehicle is started, the engine oil life system has not reset. Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that can be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin for
very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine
oil. See the manufacturer's warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil
by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Recycle it by taking it to a place that collects used
oil.
