GETTING TO KNOW YOUR INSTRUMENT PANEL 131
Fuel And Oil Refresh Mode
Since it is possible to operate this vehicle for
extended periods of time without running the
gas engine, the fuel within the vehicle’s fuel
tank can become stale or the engine oil’s lubri-
cating properties can be reduced. To prevent
engine and/or fuel system damage due to stale
fuel, as well as, maintaining internal engine
lubrication, this vehicle is equipped with a
“Fuel and Oil Refresh Mode”.
The vehicle will automatically enter into the Fuel
and Oil Refresh Mode to minimize potential for
stale fuel, and to ensure lubrication of internal
engine components. When operating in this
mode, the gas engine will run to provide vehicle
propulsion (electric only operation is inhibited).
A message will be displayed in the instrument
cluster whenever Fuel and Oil Refresh Mode is
active.
The vehicle will automatically exit the Fuel and
Oil Refresh Mode when conditions have been
satisfied. If the vehicle enters Fuel and Oil
Refresh Mode, due to fuel which has been in the
fuel tank for a long period of time (becoming
stale fuel), the engine will run whenever the
vehicle is operational (no electric only opera-
tion) until the low fuel level warning is activated.
It is also possible to exit the Fuel and Oil Refresh
Mode sooner by adding a minimum of 4 gallons
of new fuel to the vehicle’s fuel tank.
NOTE:
If the vehicle enters Fuel and Oil Refresh Mode
to maintain engine lubrication, adding fuel will
not exit the mode sooner.
If the vehicle enters Fuel and Oil Refresh Mode
to maintain engine lubrication properties, the
engine may run for a period of up to 20 minutes
when fully warm whenever the vehicle is opera-
tional (no electric only operation). If the vehicle
is shut down before conditions to exit the
refresh mode have been satisfied, the engine
may run for additional time on subsequent trips.
NOTE:
Frequent short trips at low ambient tempera-
ture conditions are more likely to trigger the
lubrication based mode.
