✽ ✽NOTICE
Coasting guide is only a supplemen-
tal system to assist with fuel-efficient
driving in certain situations. Thus,
the operating conditions may be dif-
ferent in accordance with
traffic/road conditions (i.e. driving
in a traffic jam, driving on a slope,
driving on a curve). Thus, take the
actual driving conditions into con-
sideration, such as distances from
the vehicles ahead/ behind, while
referring to the coasting guide sys-
tem as guidance.

AUX. BATTERY SAVER+ (For
Plug-in Hybrid, if equipped)
The Aux. Battery Saver+ is a function
that monitors the charging status of
the 12V auxiliary battery.
If the auxiliary battery level is low, the
main high voltage battery charges
the auxiliary battery.
✽ ✽NOTICE
The Aux. Battery Saver+ function will
be ON when the vehicle is delivered. If
the function is not needed, you may
turn it off in the Users Settings mode
on the LCD display. For more infor-
mation, refer to the "System setting"
on the following page.
Mode

When the vehicle is OFF with all
doors, hood and liftgate closed, the
Aux. Battery Saver+ periodically acti-
vates according to the auxiliary bat-
tery status.

When the engine start/stop button is
in the ON position with the charging
connector plugged in, this function
activates according to the auxiliary
battery status to prevent over-dis-
charge of the auxiliary battery.
✽ ✽NOTICE
The Aux. Battery Saver+ activates
for a maximum of 20 minutes. If the
Aux. Battery Saver+ function acti-
vates more than 10 times consecu-
tively, in the Automatic Mode, this
function will stop activating, judg-
ing that there is a problem with the
auxiliary battery. In this case, drive
the vehicle for some period of time.
The function will start activating if
the auxiliary battery returns to nor-
mal.
✽ ✽NOTICE
If the Aux. Battery Saver+ function
was activated, a message will be dis-
played on the instrument cluster
and the high voltage battery level
may have decreased.

WARNING
The Aux. Battery Saver+ relies
on the high voltage battery to
charge the 12V battery. The
charging indicator lamp will blink
rapidly when this is occurring.
To reduce the risk of electrical
shock, do not touch any high
voltage components (orange) or
other electrical devices while
charging is occurring.
