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
seating floor trim) The high-voltage battery stores and outputs
DC power (Maximum voltage 144V) needed to
propel the vehicle.
Traction Motor Engine compart-
ment (built-into the
transmission) Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.
Traction Motor
Inverter Engine compart-
ment (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 compart-
ment A lead-acid battery that supplies power to the
low voltage devices.

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 (B C D E) . • 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.
If the green READY light does not come on, press the START button to turn the
Hybrid
System OFF. Carefully disconnect the negative cable then the positive cable. It is
recommended the vehicle is taken to an INFINITI retailer for repair. AAYIA0072GB
