24 In Brief
Regular Fuel
Use only unleaded gasoline rated
87 octane or higher in your vehicle.
Do not use gasoline with an octane
rating lower as it may result in
vehicle damage and lower fuel
economy. SeeFuel0193.
E85 or FlexFuel
No E85 or FlexFuel
Gasoline-ethanol fuel blends greater
than E15 (15% ethanol by volume),
such as E85, cannot be used in this
vehicle.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays the CHANGE ENGINE OIL SOON DIC message when it is
necessary to change the engine oil
and filter.
Remember, the oil life display must
be reset after each oil change. It will
not reset itself. Also, be careful not
to reset the oil life display
accidentally at any time other than
when the oil has just been changed.
It cannot be reset accurately until
the next oil change.
Resetting the Oil Life System
1. Press the MENU button to show Remaining Oil Life on the
display. This display shows an
estimate of the oil’s remaining
useful life. If 99% is displayed,
that means that 99% of the
current oil life remains.
2. To reset the engine oil life system, press the SET/CLR
button while the oil life display
is active. After a few seconds,
there will be a single chime and
the oil life will be reset
to 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.
See
Engine Oil Life System 0209.

Engine Oil Change
When the CHANGE ENGINE OIL
SOON DIC message displays, have
the engine oil and filter changed
within the next 1 000 km/600 mi.
If driven under the best conditions,
the engine oil life system may not
indicate the need for vehicle service
for up to a year. The engine oil and filter must be changed at least once
a year and the oil life system must
be reset. Your trained dealer
technician can perform this work.
If the engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 mi since the
last service. Reset the oil life
system when the oil is changed.
