voltage battery. The vehicle can
operate in this mode until the
battery has reached a low charge.
There are some conditions when the
battery charge is high enough to
provide Electric Mode operation, but
the engine still runs. They are:
.Cold ambient temperatures.
.Hot or cold high voltage battery
temperatures.
.The hood being open or not
completely closed and latched.
.Certain high voltage battery fault
conditions.
.Engine Maintenance Mode or
Fuel Maintenance Mode
being run.
Extended Range Mode
When the vehicle reaches the end
of its electric range, it switches to
Extended Range Mode (ERM). In
this secondary mode, electricity is
produced by the fuel‐powered
engine. This secondary source ofelectric power extends the vehicle
range. Operation will continue in
ERM until the vehicle can be
plugged in to recharge the high
voltage battery and restore
Electric Mode.
The high voltage battery will
continue to provide some power and
work together with the engine to
provide peak performance when it is
required, such as driving up a steep
incline or for high acceleration
maneuvers. The battery will not be
charged nor will electric vehicle
range be restored by the engine.
In either Electric Mode or Extended
Range Mode, when the hood is
open, the engine will run without
turning off if the vehicle is on. The
high voltage battery is neither
charged nor discharged when this
occurs.
In either Electric Mode or Extended
Range Mode, if there is a high
voltage battery fault, the engine may
run without turning off to generate
needed electricity. The malfunctionindicator lamp will turn on. See
Malfunction Indicator Lamp on
page 5-17.
Driver Selected Operating
Modes
While driving in Electric or Extended
Range Mode, additional operating
modes can be selected.
Press the MODE switch to display
selectable drive modes in the Driver

Mountain Mode will not change
normal vehicle braking performance
for steep downhill grades. SeeHill
and Mountain Roads on page 9-9
and Electric Drive Unit on
page 9-28.
Press the MODE switch to select
Mountain Mode. If steep hill driving
is expected, it is recommended to
select Mountain Mode at least
20 minutes before driving on steep
grades. This will allow the vehicle
time to build a sufficient battery
charge reserve.
If Mountain Mode is not selected for
these conditions, propulsion power
may be reduced and the engine
speed may increase. See
Propulsion Power Messages on
page 5-48.
The engine may run when Mountain
Mode is selected, depending on the
high voltage battery charge, to build
reserve battery charge for uphill
climbs. The high voltage battery
charge reserved for Mountain Mode will be displayed on the battery
gauge, but will not be depleted until
it is required for uphill driving.
Press the MODE switch again to
return to Tour Mode and it becomes
active after three seconds.
Each time the vehicle is started, it
will return to Tour Mode to maintain
a smaller battery charge reserve for
normal driving.
Hold Mode
Hold Mode is only available when
the vehicle is in Electric Mode. This
mode places the remaining battery
charge into a reserve for the driver
to use as desired. Selecting thismode transitions the vehicle to
Extended Range Mode to maintain
the battery charge reserve.
Upon exiting Hold Mode, the
reserved battery charge becomes
available again and the vehicle
returns to Electric Mode. If the
transition is from Hold Mode directly
to Mountain Mode, the electric
range displayed adjusts for the
Mountain Mode charge reserve.
Press the MODE switch and scroll
to Hold Mode to select it.
Press the MODE switch again to
return to Tour Mode and it becomes
active after three seconds.
Each time the vehicle is started, it
will return to Tour Mode.
