Your vehicle has a computer system that lets you know
when to change the engine oil and filter. This is based on
engine revolutions and engine temperature, and not 
on mileage. Based on driving conditions, the mileage 
at which an oil change will be indicated can vary
considerably. For the oil life system to work properly,
you must reset the system every time the oil is changed.

When the system has calculated that oil life has 
been diminished, it will indicate that an oil change is
necessary. A CHANGE ENGINE OIL 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.

Lubricate chassis components with each engine oil and
filter change. Lubricate the front suspension, ball joints,
steering linkage, transmission shift linkage and parking
brake cable guides. Ball joints should not be lubricated
unless their temperature is 10
