2. Basic High-Voltage Information
2-1
Battery Information
The QX60 HYBRID utilizes two batteries in order to supply both high and low voltage.
2-1.1 12-Volt Battery • The QX60 HYBRID contains a conventional lead-acid12-volt battery.
• The 12-volt battery is located in the front of the vehicle on the left side of the engine compartment.
• The 12-volt battery is charged by the high-voltage battery through the DC/DC converter. : Vehicle front
2-1.2
High-Voltage Battery
• The QX60 HYBRID contains a high-voltage battery.
• The high-voltage battery is mounted in the cargo area under the 3rd row seating, enclosed in a metal case
and concealed by trim cover.
• The high-voltage battery stores approximately 144 volts DC.
• A vent hose is provided to exhaust gasses outside the vehicle if necessary.
• Air vents (A) are located on the cargo area trim panels for battery cooling.
The high-voltage battery supplies power to the following: • High-voltage harnesses
• DC/DC converter
• Traction motor inverter
• Traction motor AAYIA0300ZZ

Service
Plug Cargo area floor(inside storage bin
behind access door) This is used to disable the high-voltage sys-
tem.
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
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
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 regulat-
ing the motor current. The inverter has a built
in high-voltage capacitor.
12-Volt Battery Front of the vehicle

the engine compart-
ment A lead-acid battery that supplies power to the
low voltage devices.
High-Voltage
Harness Cargo area (on high-

2-4 High-Voltage Safety Measures
Circuit insulation
The high-voltage positive (+) and negative (-) circuits are insulated
from the metal chassis.
Reducing the risk of electrocution The high-voltage components and harnesses have insulated cases or orange-colored coverings which provide insulation and easy
identification.
The high-voltage battery case is electrically connected to the vehicle
ground. This connection helps protect the vehicle occupants and
emergency responders from high-voltage electrical shock.
Identification The high-voltage components are labeled “WARNING” similar to the
label shown below. All high-voltage harnesses are coated in orange.
2-4.1 Warning Label AAYIA0010ZZ

3. Roadside Assistance Response Steps
• NEVER assume the QX60 HYBRID is shut OFF simply because it is quiet.
• If the vehicle is damaged and you are not sure about the condition of the electric
vehicle system, contact first responders immediately. If the vehicle is damaged, the
high-voltage system should be shut down by first responders while following the
procedures in the First Responders Guide and while wearing appropriate Personal
Protective Equipment (PPE) .
• If the READY indicator is ON the high-voltage system is active.
• If possible, be sure to check the READY indicator on the instrument cluster and
verify

that the READY indicator is OFF and the high-voltage system is stopped.
•

Some of the under hood parts get hot and may cause serious burns. Use caution when
working on or around these parts.

3-1.1 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.
3-1.2 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)
3-1.3 Insulated Tools
When performing work at locations where high-voltage is applied (such as terminals) , use insulated tools
meeting 1,000V/300A specifications.
3-2 Indications the High-Voltage System is ON
If the READY indicator is ON, the high-voltage system is active.
Before

disconnecting the 12-volt battery terminal, if necessary, lower the windows, unlock the doors, and
open the rear hatch as required. Once 12-volt battery is disconnected, power controls will not operate.
