Functions
PERFORMANCE SHIFT: This light comes on when
you press the performance shift button (located on the
console shift) to indicate that the vehicle is in
performance shifting mode.
See "Performance Shifting" in the Index.
FUEL USED: Shows the total amount of fuel used
since you last reset this mode. The amount can be
displayed in gallons or liters.
2-90
AVG ECON: Shows the average fuel economy since
you last reset this mode.
OIL LIFE: Shows a percentage of the oil's remaining
useful life. The system predicts remaining oil life using
inputs from length of drives, coolant temperature,
engine rpm and vehicle speed. Each time you get an oil
change, be sure to reset this function so that it will give
you an accurate percentage. See "How to Reset the Oil
Life Monitor" in the Index.
RANGE: Shows how much farther you can travel with
the fuel you have before refueling. When the range
displays L, for 40 to 50 miles (64.36 to 80.45 km), the
display will flash the word LOW continuously and the
vehicle will chime three times. The range is calculated
from the average econ value times the fuel remaining in
the tank.
LOW: This light will come on when the ignition is
on and the fluid container is low.
