24 In Brief
Fuel
Regular Unleaded Fuel
Use only Regular 87 octane—
(R+M)/2 —or higher unleaded
gasoline in your vehicle. TOP TIER
Detergent Gasoline is
recommended. Do not use gasoline
with an octane rating lower as it will
result in reduced performance and
lower fuel economy. See
Recommended Fuel 0240.
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 message 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. Display the REMAINING OIL LIFE on the DIC. See Driver
Information Center (DIC) (Base
and Midlevel) 0144 or
Driver Information Center (DIC)
(Uplevel) 0147.
2. Press and hold the thumbwheel on the DIC while
the Oil Life display is active. 3. Confirm yes, and the oil life will
change to 100%.
See Engine Oil Life System 0267.
Driving for Better Fuel
Economy
Driving habits can affect fuel
mileage. Here are some driving tips
to get the best fuel economy
possible.
.
Set the climate controls to the
desired temperature after the
engine is started, or turn them
off when not required.
. On AWD vehicles, see Driver
Mode Control 0210.
. Avoid fast starts and accelerate
smoothly.
. Brake gradually and avoid
abrupt stops.
. Avoid idling the engine for long
periods of time.

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 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 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.
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. Display the REMAINING OIL LIFE on the DIC. See Driver
Information Center (DIC) (Base
and Midlevel) 0144 or
Driver Information Center (DIC)
(Uplevel) 0147.
2. Press and hold the thumbwheel on the DIC while
the Oil Life display is active.
3. Confirm yes, and the oil life will change to 100%. The oil life system can also be reset
as follows:
1. Place the ignition in Service Mode. See Ignition Positions
0 192.
2. Display REMAINING OIL LIFE on the DIC menu. See Driver
Information Center (DIC) (Base
and Midlevel) 0144 or
Driver Information Center (DIC)
(Uplevel) 0147.
3. Fully press and release the accelerator pedal three times
within five seconds.
4. If the display changes to 100%, the system is reset.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not been reset. Repeat
the procedure.
