NOTE: There is also an engine hour function. This
indicates the total number of hours the engine has been
running. To display the engine hours on the base cluster,
perform the following: Place the ignition in the ON/
RUN, but do not start the engine. With the odometer
value displayed, hold the TRIP button down for a period
of six seconds. The odometer will change to trip value
first, then it will display the engine hour value. The
engine hours will be displayed for a period of 30 seconds
until the ignition is turned OFF or the engine is started.
If equipped, some of the above warnings will be dis-
played in the Electronic Vehicle Information Center
(EVIC) in the instrument cluster. Refer to ”Electronic
Vehicle Information Center (EVIC) — If Equipped” for
further information.
ECO / ECO-ON (Fuel Saver Indicator) — If Equipped
The ECO-ON indicator will illuminate when you are
driving in a fuel efficient manner and can be used to
modify driving habits in order to increase fuel economy.
The ECO display will toggle between ECO and ECO-ON
depending on driving habits and vehicle usage. Press the
Odometer / Trip Odometer / ECO (Fuel Saver Indicator)
button to change the display from odometer to either of
the two trip odometer settings or the “ECO” display.
If the vehicle diagnostic system determines
that the fuel filler cap is loose, improperly
installed, or damaged, a loose gascap indicator
will display in the odometer display area.
Tighten the fuel filler cap properly and press
the TRIP button to turn off the message. If the
problem continues, the message will appear
the next time the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the Malfunction Indicator Light (MIL).
