Fuel Economy
Pressing the SELECT down arrow while in the
ECON mode displays average fuel economy and
instantaneous fuel economy calculated for your
specific driving conditions.
Average fuel economy will be shown in a reading
such as:
25.2 AVG MI/GAL or 9.3 AVG L/100 KM
Instantaneous fuel economy will be shown in a reading
such as:
28 INST MI/GAL or 8.4 INST L/100 KM
The average fuel economy is viewed as a long
-term
approximation of your overall driving conditions.
If you press and hold RESET for three seconds in this
mode while you’re driving, the system will begin
figuring average fuel economy from that point in time.
Instantaneous fuel economy cannot be reset.
Oil Life
The GM Oil Life System is the only function
accessible in the OIL mode. Engine oil life is displayed
in a reading such as the following:
OIL LIFE 30%
This is an estimate of the oil’s remaining useful life.
It will show 100% 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 this message:
CHANGE OIL SOON
Always reset the OIL LIFE reminder after an oil change.
To reset the oil life system, see “Oil Life System” in
the Index. Also, see “Engine Oil, When to Change” in
the Index.
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.
