When the CHANGE OIL SOON message in the
Driver Information Center (DIC) comes on, it means
that service is required for your vehicle. SeeDIC
Warnings and Messages on page 184. 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 298for information on the Engine Oil Life
System and resetting the system.
