Short Trip/City Scheduled Maintenance
7-9
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A CHANGE ENGINE OIL SOON message
will come on. Change your oil as soon as possible
within the next two times you stop for fuel. It is possible
that, if you are driving under the best conditions, the oil
life system may not indicate that an oil change is
necessary for over a year. However, your 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 your oil regularly and keep it at the proper level. If the system is ever reset accidentally, you must change
your oil at 3,000 miles (5 000 km) since your last oil
change. Remember to reset the oil life system whenever
the oil is changed. See “Oil Life System” in the Index
for information on resetting the system.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection” under
“Periodic Maintenance Inspections” in Part C of
this schedule.
@ Whenever the tires are rotated, the Check Tire
Pressure System (if equipped) must be reset.
