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.
Using the 12V battery reset switch
ONX4HQ010015
1. Press the 12V Battery Reset switch to
r
econnect the 12V battery.
2.
Start the v

ehicle within 15 seconds of
pressing the 12V Battery Reset switch.
3.
Aft

er starting the vehicle
(
indicator on), operate the vehicle
safely outdoors in ready mode
stopped and/or drive it for 30 minutes
total to charge the 12V battery fully. If you do not start the vehicle
immediately after pressing the 12V
Battery Reset switch, the power of 12V
battery 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 battery, 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.

After starting the vehicle
( indicator on), the 12V battery is being
charged whether the engine is running or
not. Although there is no engine sound, it
is unnecessary to depress the accelerator
pedal.
The following items may need to be reset
after the battery has been discharged or
the battery has been disconnected.
