Location Description
DC/DC
Converter Cargo
area floor
(mounted right 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 vehicle’s
electric components (headlights, audio system,
etc.) .
Service Plug Cargo area floor
(inside storage bin
behind access door) This is used to disable the high-voltage system.
High-Voltage
Battery Cargo area floor
(under 3rd row seat-
ing floor trim) The high-voltage battery stores and outputs DC
power (Maximum voltage 144V) needed to pro-
pel the vehicle.
Traction Motor Engine compartment
(built-into the trans-
mission) Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.
Traction Motor
Inverter
Engine compartment
(front driver 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.
12-Volt Battery
Front of the vehicle
on the left side of the
engine compartmentA lead-acid battery that supplies power to the
low voltage devices.

SRS Air Bag System Components Location
The
SRS air bag system must not be cut as there is a risk of short circuit and unintentional deployment of
the SRS. However, the vehicle can be cut (except inflators) under the following conditions: • The front, side and curtain air bags have deployed.
• At least three (3) minutes have passed after the 12-volt battery negative (-) cable has beendisconnected and the high-voltage system has been shut down.
1. Roof-mounted curtain side-
impact and rollover supplemental
air bag inflators 2. Air bag control unit (ACU) 3. Supplemental front-impact air
bag modules
4. Pressure sensors (driver’s side
door shown; passenger side door
similar) 5. Crash zone sensor
6. Satellite sensors (RH shown,
