necessary. A CHANGE ENGINE
OIL SOON message comes on. See
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 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
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.
.
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. Always reset the
engine oil life to 100% after every oil
change. It will not reset itself.
To reset the system:
1. Display OIL LIFE REMAINING
on the DIC.
2. Press and hold the SET/RESET
button on the DIC for more than
five seconds. The oil life will
change to 100%.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not reset. Repeat the
procedure.
It is not necessary to check
the transmission fluid level.
A transmission fluid leak is the
only reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer and have it repaired as
soon as possible.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, you should
have this done at your dealer.
Contact your dealer for additional
information or the procedure can be
found in the service manual. To
purchase a service manual, see
