Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and turns on the change engine oil
light when it is time to change the
engine oil and filter. The oil life
system should be reset to 100%
only following an oil change.
Resetting the Oil Life System
1. Press the DIC vehicleinformation button to display OIL
LIFE REMAINING on the DIC.
2. Press the DIC Set/Reset button for during 5 seconds to 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. It cannot be reset
accurately until the next oil
change. The oil life system can also be reset
as follows:
1. Turn the ignition key to ON/RUN
with the engine off.
2. Fully press and release the accelerator pedal three times
within five seconds.
If the change engine oil light is
not on, the system is reset.

Oil Flushes
Do not add anything to the oil.
The recommended oils with the

good performance and engine
protection.
Engine oil system flushes are not
recommended and could cause

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 engine revolutions and engine
temperature, and not on mileage.
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 oil light
comes on. See
Change Engine Oil
Light
on page 5‑22. Change the oil
as soon as possible within the next
1 000 km (600 miles). It is possible
that, if driving under the best
conditions, the oil life system might
not indicate that an oil change is
necessary for over a year. However,
the engine oil and filter must be
changed at least once a year and at
this time the system must be reset.
Your dealer/retailer has trained
service people who will perform this
work using genuine parts and reset
the system. It is also important to
check the oil regularly 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 miles)
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
The Engine Oil Life System
calculates when to change the
engine oil and filter based on
vehicle use. Whenever the oil is
changed, reset the system so it can
calculate when the next oil change
is required. If a situation occurs
where the oil is changed prior to a
change engine oil message being
turned on, reset the system.
ProCarManuals.com
Vehicle Care 10-11
After changing the engine oil, reset
the system:
1. Press the DIC vehicleinformation button to display OIL
LIFE REMAINING on the DIC.
See Driver Information Center
(DIC)
on page 5‑25and Engine
Oil Messages on page 5‑33.
2. Press the DIC Set/Reset button for during 5 seconds to 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. It cannot be reset
accurately until the next oil
change. The oil life system can also be reset
as follows:
1. Turn the ignition key to ON/RUN
with the engine off.
2. Fully press and release the accelerator pedal three times
within five seconds.
If the change engine oil light is
not on, the system is reset.
If the change engine oil light
comes on again and stays on for
30 seconds at the next ignition
cycle, it did not reset. The system
needs to be reset again.
What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer's warnings about the
use and disposal of oil products.
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, 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.
