When the CHANGE ENGINE OIL SOON message
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 314for information on the Engine Oil Life
System and resetting the system.
