No. Component Location Description DC/DC Converter Cargo area floor
(mounted right of
Li-ion battery) The DC/DC converter reduces the voltage of
the Li-ion battery to provide power to the 12V
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.
Lithium-ion (Li-ion)Battery Cargo area floor
(under 3rd row
seating floor trim) The Li-ion battery stores and outputs DC
power (Maximum voltage 144V) needed to
propel the vehicle.
Traction Motor Engine compart-
ment (built-into thetransmission) Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.
Traction MotorInverter Engine compart-
ment (front driverside) Converts the DC power stored in the Li-ion
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.
12V Battery Engine compart-
ment (front driverside) A lead-acid battery that supplies power to the
low voltage devices.
High Voltage Har-ness Cargo area (on
Li-ion battery) ,
under floor, enginecompartment Orange-colored power cables carry high DC
voltage between each of the high voltage com-ponents.

4-1 Jump Starting Procedures
NOTE: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 (B C D E) .
• Always connect positive (+) to positive (+) and negative (-) to body ground (for example,
as illustrated) , not to the 12V 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.
