collects used oil.
Engine Oil Life
System
When to Change
Engine Oil
This vehicle has a computer
system that indicates when to
change the engine oil and
filter. This is based on a
combination of factors which
include engine revolutions,
engine temperature, and miles
driven. Based on driving
conditions, the mileage at
which an oil change is
indicated can vary
considerably. For the oil life
system to work properly, the
system must be reset every
time the oil is changed.
When the system has
calculated that oil life has been
diminished, it indicates that an
oil change is necessary.
A CHANGE ENGINE OILSOON message comes on.
Change the oil as soon as
possible within the next
1 000 km (600 mi). It is
possible that, if driving under
the best conditions, the oil life
system may indicate that an oil
change is not necessary for up
to a year. The engine oil and
filter must be changed at least
once a year and at this time
the system must be reset.
Your dealer has trained
service people who will
perform this work and reset
the system. It is also important
to check the oil regularly over
the course of an oil drain
interval and keep it at the
proper level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km
(3,000 mi) since the last oil
change. Remember to reset
the oil life system whenever
the oil is changed.
How to Reset the Engine
Oil Life System
Reset the system whenever
the engine oil is changed so
that the system can calculate
the next engine oil change. To
reset the system:
1. Using the DIC controls on the right side of the
steering wheel, display
REMAINING OIL LIFE on
the DIC. See Driver
Information Center (DIC)
0136. When remaining oil
life is low, the CHANGE
ENGINE OIL SOON
message will appear on the
display.
2. Press
Von the DIC
controls and hold down for
a few seconds to clear the
CHANGE ENGINE OIL
SOON message and reset
the oil life at 100%.
Be careful not to reset the
oil life display accidentally
at any time other than
after the oil is changed.
