Energy Usage Score
The Energy Usage Score screen
provides an estimate of the factors
that influence energy usage since
the last full charge of the high
voltage battery. A positive score is
desired to reach the vehicle’s
electric and fuel economy rating.
.Technique includes accelerating
and braking.
. Terrain includes road conditions,
such as hills, rain, and snow and
may be affected by wind and tire
pressure.
. Climate Settings includes how
the heating and air conditioning
are used. .
Outside Temperature includes
the effect that hot or cold air has
on vehicle aerodynamics.
. Score is the sum of the
individual scores.
The individual scores provide an
understanding of how electric and
fuel economy are different from
day-to-day, even when traveling the
same route.
All values are reset after a complete
charge and may not be stable until
approximately 16 km (10 mi) have
been driven.
Energy Details
The Energy Details screen displays
how energy is being used since the
last time the high voltage battery was fully charged. It includes
Driving and Accessories, Climate
Settings, and Battery Conditioning.
The circle graph displays
these percentages. The total energy
used displays at the bottom of the
screen.

reset by pressing and holding
V
while this display is active.
The Average Fuel Economy display
shows the approximate average
liters per 100 kilometers (L/100 km)
or miles per gallon (mpg). This
number is calculated based on the
number of L/100 km (mpg) recorded
since the last time this menu item
was reset. This number reflects only the approximate average fuel
economy that the vehicle has right
now, and will change as driving
conditions change. The Average
Fuel Economy can be reset along
with the trip odometer by pressing
and holding
Vwhile this display is
active.
Compass and Speed : Shows the
direction the vehicle is driving and

kilometers per hour (km/h) or miles
per hour (mph).
Total Range : Shows the remaining
distance the vehicle can be driven
combining the electric range and
fuel range.
Oil Life : The Oil Life display shows
an estimate of the oil's remaining
useful life. If REMAINING OIL LIFE
99% is displayed, that means 99%
of the current oil life remains.
When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
The oil should be changed as soon
as possible. See Engine Oil0240.

Automatic Climate
Control System
The heating, cooling, and ventilation
for the vehicle can be controlled
with this system.
The vehicle may require the use of
an auxiliary heat source under
certain cold conditions. This
provides additional heating and
defrost capability obtained by
running the engine, even if the high
voltage battery is adequately
charged. Under these conditions,
the engine will start and use fuel.
Make sure there is fuel in the tank. Do not allow the vehicle to remain in
extreme temperatures for long
periods without being driven or
plugged in.

vehicle's electric range or fuel
economy.
To select a climate mode,
press eco.
Fan Only Mode :
To select this
mode, turn off both eco and MAX
mode. The air conditioning and
electric heat are turned off. As long as
0MAX is not selected, the

economy will decrease depending
on the amount of energy required to
reach the best comfort levels.
The air conditioning and electric
heat could be on at the same time
when dehumidification is required in
eco or MAX modes. The air conditioning may also run if
0MAX is selected, regardless of
the climate mode.
Automatic Operation
