Change Oil Soon Light (Option)
CHANGE
OI L SOON
This light is activated by the
Engine Oil Life Monitor
System. The Engine Oil
Life Monitor determines the
condition of the engine oil
and lets you know when the
oil should be changed. See
"Engine Oil" in the Index.
It
does this by electronically receiving data from the
Powertrain Control Module. The data it receives
contains information about engine speed (revolutions
per minute), coolant temperature and vehicle speed. The
Engine Oil Life Monitor uses this data to determine how
much the oil has degraded.
When
to
change your oil depends on driving habits and
conditions because these directly affect engine speed,
coolant temperature and vehicle speed. Because of this,
the CHANGE OIL SOON light may come on as early as
2,000 miles or less for harsh circumstances.
The CHANGE OIL SOON light is lit for five seconds as
a bulb check each time the ignition key is turned to the
RUN position. It will stay on for 60 seconds once
90%
of the oil life has been used and each time the engine is
started after that. If the CHANGE OIL SOON light is
on
continuously, there is a problem with the Oil Life
Monitor System and service is required.
After changing the engine oil, the system should be
reset. This will cause the CHANGE OIL SOON light to
be lit for a bulb check period of three seconds.
The reset button is in the glove box. With the ignition
key in the RUN position, push the reset button, hold it in
for at least five seconds but not more than 60 seconds.
After five seconds, the CHANGE OIL SOON light will
flash four times and then go off. This indicates that the
Oil Life Monitor System has been reset.
