Before Jump Starting

This vehicle does not have a regular
12V battery that needs periodic
replacement. It is lithium ion polymer
type integrated into the HEV high
voltage battery. The vehicle has a
12V battery protection system that
cuts 12V battery from vehicle draw to
prevent full discharge.

1. Press the 12V Battery Reset
switch to reconnect the 12V bat-
tery.
2. Start the vehicle within 15 sec-
onds of pressing the 12V Battery
Reset switch.
3. After starting the vehicle (
indicator on), operate the vehicle
safely outdoors in ready mode
stopped and/or drive it for 30 min-
utes total to charge the 12V bat-
tery fully.
If you do not start the vehicle imme-
diately after pressing the 12V Battery
Reset switch, the power of 12V bat-
tery is automatically disconnected
after few seconds to save the 12V
battery from additional discharge. If
the 12V battery is disconnected prior
to starting the vehicle, press the 12V
Battery Reset switch again and then
immediately start the vehicle as
explained.
Repeated use of the 12V Battery
Reset switch without a sufficient
engine ON cycle (30 Min+) may
cause over discharge of the 12V bat-
tery, which will prevent the vehicle
from starting. If the 12V battery is
over discharged to a point that the
reset does not work, try to jump-start
the vehicle.
