Before Jump Starting

Using the 12V BATT RESET button
This vehicle does not have a regular 12 V
battery that needs periodic replacement.
It is lithium ion type integrated into the
high voltage hybrid battery. The vehicle
has a 12 V battery protection system that
cuts 12 V battery from vehicle draw to
prevent full discharge. To charge the 12 V
battery, you should try pressing the 12V
BATT RESET button or the power tailgate
open button.
To Charge the 12 V battery:
1. When the 12 V battery is discharged,
you cannot open the door with the
smart key. If the door is locked, press
the power tailgate open button. If the
door is open, press the 12V BATT RESET
button on the left side of the steering
wheel.

2. Start the vehicle within 30 seconds
after pressing the 12V BATT RESET
button.
3. After starting the vehicle (READY
indicator on), operate the vehicle safely
outdoors in ready mode stopped
and/or drive it for 30 minutes total to
charge the 12 V battery fully.
If you do not start the vehicle 30 seconds
after pressing the 12V BATT RESET
button, the power of 12 V battery is
automatically disconnected after few
seconds to save the 12 V battery from
additional discharge. If the 12 V battery is
disconnected prior to starting the vehicle,
press the 12V BATT RESET button again
and start the vehicle as explained.
Repeated use of the 12V BATT RESET
button without a sufficient engine ON
cycle (30 Min+) may cause over discharge
of the 12 V battery, which will prevent the
vehicle from starting. If the 12 V battery is
over discharged to a point that the reset
does not work, try to jump start the
vehicle.
Information
After starting the vehicle (READY
indicator on), the 12 V 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.
