2-2 High Voltage-Related and 12-Volt-Related Component Locations and Descriptions
=DANGER
NOTE:Components with white number in black background are high voltage components.
No. Component 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.) .

No. Component Location Description Service Plug Cargo area floor
(inside storage bin
behind access door) This is used to disable the high voltage system.
High VoltageBattery Cargo area floor
(under 3rd row
seating floor trim) The high voltage battery stores and outputs
DC power (Maximum voltage 144V) needed to
propel the vehicle.
Traction Motor
Engine compartment
(built-into the trans-mission)Converts three-phase alternating current (AC)
power to drive power (torque) which propels thevehicle.
Traction MotorInverter
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.
High VoltageHarness Cargo area (on high
voltage battery) ,
under floor, enginecompartment Orange-colored power cables carry high
DC voltage between each of the high voltagecomponents.

3-2 Personal Protective Equipment (PPE) and Insulated Tools
3-2.1 Personal Protective Equipment (PPE) Protective Wear Control
Perform an inspection of the Personal Protective Equipment (PPE) items before beginning work. Do not use
any damaged PPE items.
3-2.2 Daily Inspection
This inspection is performed before and after use. The worker who will be using the items should perform
the inspection and check for deterioration and damage.• Insulated rubber gloves should be inspected for scratches, holes and tears. (Visual check and airleakage test)
• Insulated safety boots should be inspected for holes, damage, nails, metal pieces, wear or other problems on the soles. (Visual check)
• Insulated rubber sheet should be inspected for tears. (Visual check)
3-2.3 Insulated Tools
When performing work at locations where high voltage is applied (such as terminals) , use insulated tools
meeting 1,000V/300A specifications.
3-3 Discharge Procedures
DANGER
Do not perform this procedure if the battery is damaged. If you are unsure of battery
damage, use extreme caution and wear appropriate Personal Protective Equipment (PPE) .
High voltage battery discharging must take place before dismantling. Sufficient discharging can be achieved
by following these steps. 1. Place the shift selector into the Park (P) position
2. Apply the parking brake.
3. Set wheel chocks to ensure the vehicle is completely immobilized.
4. Fasten the driver seat belt and close the driver door.
5. Apply foot brake and press the ignition switch to turn the system ON. Confirm READY
indicator in instrument cluster turns ON.a. If the engine starts, leave the engine running until reaching normal operating temperature and the idling stops. It may take more than 10 minutes for complete engine warm up and
idling to stop.
b. If the engine is at normal operating temperature and does NOT start, move on to next step.
6. Remove the shift lock cover (A) using a suitable tool.
7. Push down the shift lock (B) as shown in the illustration.
8. Push the shift selector button (C) and move the shift selector to Neutral (N) position (D) while holding down
the shift lock.
NOTE:
DO NOT press accelerator or foot brake after
moving the shift selector to the Neutral (N)
position. Otherwise high voltage battery will
start to be charged.

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 doorsimilar) 5. Crash zone sensor 6. Satellite sensors (RH shown,
LH similar)
7. Front seat-mounted side-
impact supplemental air bags 8. B-pillar satellite sensors
(RH shown, LH similar)9. Seat belts with pretensioners
