9-24 Driving and Operating
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.
