LocationDescription
T
raction Motor
Inverter
Engine compartment
(right rear side)Converts the DC power stored in the high-
voltage battery to three-phase AC power and
controls motor torque (revolution) by regulating
the motor current. The inverter has a built in
high-voltage capacitor.
Traction Motor Built-into the
transmission Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.
High-voltage
Battery
Trunk area (behind
rear seat back) The high-voltage battery stores and outputs
DC power (Maximum voltage 400V) needed to
propel the vehicle.
DC/DC Converter
Trunk area (mounted
to top of high-voltage
battery)The DC/DC converter reduces the voltage of
the high-voltage battery to provide power to
the 12-volt battery in order to operate the vehi-
cle’s electric components (headlights, audio
system, etc.) .
Service Plug Trunk area (below
parcel shelf; behind
access door in trim
panel) This is used to disable the high-voltage system.
12-volt Battery Trunk area (left side
behind trim panel) A lead-acid battery that supplies power to the
low voltage devices.
High-voltage
Harnesses Trunk area (on high-
voltage battery) ,
under floor pan,
engine compartment Orange-colored power cables carry high DC
voltage between each of the high-voltage com-
ponents.

35. Follow the procedure below to remove the battery pack from inside the trunk room.
a. Attach carabiners (A) of sufficient capacity to hold battery weight, in the positions as shown
in the figure, then connect a belt slinger (B) to it. DANGER
Touching high-voltage components without wearing appropriate Personal Protective
Equipment

(PPE) will cause electrocution.
b. Slightly lift battery pack by using an engine crane (A) . DANGER
Touching high-voltage components without wearing
appropriate

Personal Protective Equipment (PPE) will
cause electrocution.
c. Remove the bracket RH (1) . A B
