10-16 Vehicle Care
When the system has calculated
that oil life has been diminished,
it indicates that an oil change is
necessary. A CHANGE ENGINE
OIL SOON 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 might indicate that an oil
change is not necessary for up
to two years. The engine oil and
filter must be changed at least
once every two years 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. Use the SELECT knob to selectOIL LIFE on the DIC menu.
2. Press SELECT to start the OIL LIFE reset procedure.
3. The DIC menu will display “Are
you sure that you want to reset?”
Use SELECT to choose YES to
reset oil life or NO to exit and
return to the previous menu.
4. If YES is selected, the DIC menu will display RESET OIL LIFE for
a short time and then 100% OIL
LIFE will be displayed when
OIL LIFE is successfully reset.
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.
Engine Air Cleaner/Filter
See Engine Compartment Overview
on page 10‑10 for the location of the
engine air cleaner/filter.
When to Inspect the Engine Air
Filter
Inspect the air filter at the scheduled
maintenance intervals and replace
it at the first oil change after each
80 000 km (50,000 mi) interval.
See Scheduled Maintenance on
page 11‑2 for more information.
If driving in dusty/dirty conditions,
inspect the air filter at each engine
oil change.
How to Inspect the Engine Air
Filter
To inspect the air filter, remove it
from the engine air cleaner/filter
assembly and lightly shake to
release loose dust and dirt. If the
air filter remains covered with dirt,
a new air filter is required.
