
cold - Some systems require warm up to func-
tion properly if the outside temperature is below
32°F (15°F in Electric Drive mode).
Electric cabin heating capacity limits (or electric

cabin heater fault) - Unlike Battery Electric Vehi-
cles (BEV's), the PHEV Wrangler can warm the
cabin more efficiently with engine heat when
operating below 15°F outside temperature.
HV battery, motors or contactors over tempera-

ture - This is a temporary hardware protection
feature. Vehicle performance will resume
once protection is no longer required. If the
vehicle performance is accompanied with a
Malfunction Indicator Lamp (MIL)
vehicle serviced at an authorized dealership.
Component Protection that can inhibit Electric
mode
HV battery undervoltage - Sustained EV opera-

tion at high speed, especially with aftermarket
wheels and tires, can induce this.
Other electric propulsion system faults indi-

cated by a MIL - Please bring the vehicle to your
dealership for service.
Fuel And Oil Refresh mode - See the following

section.
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 lubricating
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.
, have the
Fuel and Oil Refresh Mode Message
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 fuel and lubrication 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 operation) 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 four 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 2.5 hours when fully
warm whenever the vehicle is operational (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. Oil refresh may take
significantly longer in freezing temperatures.
