The average fuel economy is viewed as a long-term
approximation of your overall driving conditions.
If you press RESET in this mode while you're
driving, the system will begin figuring fuel economy
from that point in time.
Press FUEL again to display instantaneous fuel
economy, such as:

INST. 20.1 MPG or

INST. 5.3 L/100 km
Press FUEL again to display the range, such as:

RANGE 20 MI or

RANGE 32 km
The range calculates the remaining distance you can
drive without refueling. It's based on fuel economy and
the fuel remaining in the tank.
If the range is lower than 30 miles (48 km), the display
will read RANGE LOW.
The fuel economy data used to determine fuel range is
an average of recent driving conditions. As your driving
conditions change, this data is gradually updated.
Resetting the fuel range causes the fuel economy data
to be updated immediately. Press RESET to reset the
fuel range.2 GAGES
The GAGES button allows you to scroll through the
functions listed below when you press it.
Press the GAGE button to display the oil pressure, such as:

Elapsed Time
Press the TRIP button until ELAP. TIME is displayed,
such as ELAP. TIME 00:00:00.00.
When the ignition is in ON, the Driver Information
Center (DIC) can be used as a stopwatch. The display
can show hours, minutes, seconds and hundredths of
a second. The elapsed time indicator will record up to
99 hours, 59 minutes and 59 seconds, then it will reset
to zero and continue counting. (Hundredths are shown
up to 59 minutes, 59 seconds and 99 hundredths).
The display appears as ELAP. TIME 00:00:00.00 in
the elapsed time function.
You can start or stop the elapsed time by pressing
RESET. To reset the elapsed time to zero, stop the
timer by pressing RESET. Then press and hold RESET
until ELAP. TIME 00:00:00.00 appears in the DIC.
Average Speed
Press the TRIP button until the average speed is
displayed, such as:

AVERAGE SPEED 100 km/h
Press reset in this mode to start calculating the average
speed. Press and hold RESET to clear.Engine Oil Life
Press the TRIP button until the engine oil life is
displayed, such as OIL LIFE REMAIN 89%.
This is an estimate of the engine oil's remaining useful
life. It will show 99% when the system is reset after
an oil change. It will alert you to change your oil on
a schedule consistent with your driving conditions.
When the remaining oil life is low, the system will alert
you with the message CHANGE OIL SOON.
When the oil life is down to zero, you will receive the
message CHANGE OIL NOW.
Remember, you must reset the OIL LIFE yourself
after each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed.
It can't be reset accurately until the next oil change.
To reset the system, see ªHow to Reset the Change
Oil Soon Messageº in the Index.
