Used oil can be a threat to the
environment. If you change your
own oil, be sure to drain all the oil
from the filter before disposal. Never
dispose of oil by putting it in the
trash or pouring it on the ground,
into sewers, or into streams or
bodies of water. Recycle it by taking
it to a place that collects used 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 OIL
message comes on. See
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
might 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
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.
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
. Change
engine oil change. To reset
the system:
1. Turn the ignition to ON/RUN,
with the engine off .
2. Press and release the stem in
the lower center of the
instrument cluster until the OIL
LIFE message is displayed.
3. Once the alternating OIL LIFE
and RESET messages appear,
press and hold the stem until
several beeps sound. This
confirms that the oil life system
has been reset.
4. Turn the key to LOCK/OFF.
If the CHANGE OIL message
comes back on when the vehicle is
started, the engine oil life system
has not been reset. Repeat the
procedure.
