1. About the QX60 HYBRID
This
hybrid electric vehicle (HEV) uses two types of batteries. One is a 12-volt battery that is the same as
the battery in vehicles powered by internal combustion engines. The 12-volt battery is located in the front of
the vehicle on the left side of the engine compartment. The other is the high-voltage battery for the traction
motor which propels the vehicle. The high-voltage battery is located under the third row seating with service
plug access through the cargo area storage bin.
When the high-voltage battery level is low, engine output is used to generate power from the traction motor
and charge the high-voltage battery. Additionally, the vehicle system can recharge the high-voltage battery
by converting driving force into electricity while the vehicle is decelerating or being driven downhill. This
is called regenerative charging.

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

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

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.

3-7 High-Voltage Battery Damage And Fluid Leaks
The high-voltage battery contains electrolyte solution. To avoid exposure to electrolyte
solution
and serious personal injury, always wear appropriate solvent resistant Personal
Protective Equipment (PPE) and read the following precautions:
• Electrolyte solution is a skin irritant.
• Electrolyte solution is an eye irritant – If contact with eyes, rinse with plenty of water and see a doctor immediately.
• If electrolyte leak occurs, wear appropriate solvent resistant PPE and use a dry cloth to clean up the spilled electrolyte. Be sure to adequately ventilate the area.
• Electrolyte solution is highly flammable.
• Electrolyte liquid or fumes that have come into contact with water vapors in the air will create an oxidized substance. This substance may irritate skin and eyes. In these cases,
rinse with plenty of water and see a doctor immediately.
• Electrolyte fumes (when inhaled) can cause respiratory irritation and acute intoxication. Move to fresh air and wash mouth with water. See a doctor immediately.
In cases of battery case breach or electrolyte leakage, contact the fire department immediately. If you must
walk away from the vehicle, notify an appropriate responder of the fact that the vehicle is a hybrid vehicle
and contains a high-voltage system and warn all others.
High-Voltage Battery Electrolyte Solution Characteristics: • Clear in color
• Sweet odor
• Similar viscosity to water
• Since the high-voltage battery is made up of many small sealed battery modules, electrolyte solutionleakage should be minimal.
NOTE:
Other fluids in the vehicle (such as engine oil, washer fluid, brake fluid, coolant, etc.) are
the same as those in a conventional vehicle.

4-1.1 Jump Starting Procedures
NO
TE:
Jumper cable connections under the hood of the QX60 HYBRID are not connected directly
to a battery. They are connected to chassis ground and a fuse box terminal. Refer to the
following instructions and the above illustration.
1. Locate the fuse box behind the engine air cleaner.
2. Push the tab in and lift up (A) to remove the fuse box cover and expose the remote positivebattery terminal (B) .
3. If the booster battery is in another vehicle, position the two vehicles to bring their batteries near each other.
DO NOT allow the two vehicles to touch.
4. Apply the parking brake. Move the selector lever the P (Park) . Switch off all unnecessary electrical systems (lights, heater, air conditioner, etc.) .
5. Remove vent caps on the battery (if so equipped) of the vehicle with battery for booster. Cover the battery with an old cloth (F) to reduce explosion hazard.
6. Connect jumper cables in the sequence as illustrated (BCDE) . • Always connect positive (+) to positive (+) and negative (-) to body ground (for example,
as
illustrated) , not to the 12-volt battery.
• Make sure the jumper cables do not touch moving parts in the engine compartment and that the cable clamps do not contact any other metal.
7. Start the engine of the booster vehicle and let it run for a few minutes.
8. Hold down the brake pedal and press the START button. The vehicle instruments and gauges will light up, and the green READY light will come ON. FA
