light INFINITI Q70 HYBRID 2016 Dismantling Guide

No. Component Location Description High Voltage Battery Trunk area (behind
rear seat back) The high voltage battery stores and outputs
DC power (Maximum voltage 400V) needed to
propel the vehicle.
DC/DC Converter Trunk area (mounted
to top 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 vehi-
cle’s electric components (headlights, audio
system, etc.) .
Service Plug Trunk area (below
parcel shelf; behind
access door in trimpanel) This is used to disable the high voltage system.
12-volt Battery Trunk area (below
parcel shelf; behind
trim panel left of
high voltage battery) A lead-acid battery that supplies power to the
low voltage devices.
High VoltageHarnesses Trunk area (on high
voltage battery) ,
under floor pan,
engine compartment Orange-colored power cables carry high DC
voltage between each of the high voltage com-ponents.
Electric Air Condi-
tioner Compressor
Engine compartment
(front driver side)Air conditioner compressor
Traction MotorInverter
Engine compartment
(right rear side)Converts the DC power stored in the high volt-
age battery to three-phase AC power and con-
trols motor torque (revolution) by regulating the
motor current. The inverter has a built in high
voltage capacitor.
Traction Motor Built-into the
transmission Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.

4-1 Jump Starting ProceduresJumper cable connections under the hood of the Q70 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.
If the booster battery is in another vehicle (A) , position the two vehicles (A) and (B) to bring the
battery of booster vehicle (A) and the fuse box of jumped vehicle (B) into close proximity to eachother.
DO NOT allow the two vehicles to touch.
2. Apply the parking brake. Move the selector lever the P (Park) position. Switch off all unnecessary electrical systems (headlights, heater, air conditioner, etc.) .
3. Place the ignition switch in the “OFF” position.
• 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.
• If the hybrid system does not start right away, push the ignition switch to the OFF position and wait ten (10) seconds before trying again.
4. Connect the jumper cables in the sequence as illustrated [(1) , (2) , (3) , (4)].
5. Start the engine of the booster vehicle (A) and let it run for a few minutes.
6. Start the hybrid system of the jumped vehicle (B) in the normal manner.
7. After the hybrid system is started, carefully disconnect the jumper cables in the opposite sequence from that illustrated [(4) , (3) , (2) , (1)].
NOTE:
If it is not possible to turn the hybrid system ON by following this procedure, it is
recommended you contact an INFINITI retailer immediately.
8. Put the fuse cover and the engine compartment cover back to the original location.
