Sport Mode
Sport Mode provides more
responsive acceleration than
Normal Mode, but can reduce
efficiency. Use Normal Mode
whenever possible.
Press the DRIVE MODE button to
select Sport Mode.
Press the DRIVE MODE button
again to return to Normal Mode
and it becomes active after
three seconds.
The Sport light comes on when
Sport Mode is selected. See Sport
Mode Light on page 5 26.
Each time the vehicle is started,
it will return to Normal Mode.
Mountain Mode
Mountain Mode should be selected
at the beginning of a trip before
climbing steep, uphill grades and
when expecting to drive in very
hilly or mountainous terrain.
This mode maintains a reserve
electrical charge of the high voltage
battery to provide better grade
climbing performance. While driving
in Mountain Mode, the vehicle will
have less responsive acceleration.

Driving and Operating
Mountain Mode will not change
normal vehicle braking performance
for steep downhill grades. See Hill
and Mountain Roads on page 9 10
and Electric Drive Unit on
page 9 32.
Press the DRIVE MODE button
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.
The engine may run when Mountain
Mode is selected. If Mountain
Mode is entered before four bars
of battery charge, the engine will
run at a higher speed to build
battery charge reserve. If Mountain
Mode is entered above four bars
of battery charge reserve, the
estimated electric range will
adjust accordingly.
