LI-ION BATTERY AVAILABLE
CHARGE GAUGE
The gauge1indicates theapproximate avail-
able Li-ion battery charge to run the vehicle.
Charge the Li-ion battery before the display
reaches the bottom line.
The low battery charge warning light
illu-
minates when the Li-ion battery available charge
gauge is getting low. Charge as soon as it is
convenient, preferably before the display reaches
the bottom line. When the display reaches the
bottom of the display and the low battery charge light illuminated, there is a very small reserve of
Li-ion battery charge remaining.
NOTE:
•
The number of segments illuminated on
the Li-ion battery available charge gauge
is determined by the available charge and
the amount of charge the Li-ion battery is
capable of storing at the current tempera-
ture.
• Temperature affects the amount of charge
the Li-ion battery is capable of storing.
The Li-ion battery is capable of storing
less power when the Li-ion battery tem-
perature is cold. The Li-ion battery is ca-
pable of storing more power when the
Li-ion battery is warm. The number of seg-
ments illuminated on the Li-ion battery
available charge gauge can change based
on the amount of power the Li-ion battery
is capable of storing. For example, when
the Li-ion battery becomes colder, more
segments on the Li-ion battery available
charge gauge illuminate because the
available charge is a greater percentage
of the Li-ion battery’s capability of storing
power. When the Li-ion battery becomes
warmer, less segments on the Li-ion bat- tery available charge gauge illuminate be-
cause the remaining energy is a lower
percentage of the Li-ion battery’s capabil-
ity of storing power.

Instant ECO driving level
The instant ECO driving level
1is displayed by
the number of bars that increase (more economi-
cal driving) or decrease (less economical driving)
depending on vehicle operation.
Long term ECO driving level
Long term ECO driving is indicated by ECO
TREE symbols. The longer the vehicle is operated
economically, the more segments of the large
ECO TREE symbol
2are displayed. When all of
the segments of the large ECO TREE symbol are
displayed, a small ECO TREE indicator
3is also
displayed, and the large ECO TREE symbol dis-
play is reset. The longer the vehicle is operated
economically, the more small ECO TREE sym-
bols are displayed. The ECO TREE symbols that
were illuminated while driving will turn off when
the vehicle power is turned off. The ECO TREE
symbols are stored in the navigation system to
show long term efficient vehicle operation.
To increase the ECO driving level and for information
about driving the vehicle efficiently, see “Improve
driving range” in the “EV overview” section.
