trunk INFINITI Q70 HYBRID 2016 Roadside Assistance Guide

1. About the INFINITI Q70 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 behind the
rear seat back with battery cable access through the trunk area. The other is the high voltage battery for the
traction motor which propels the vehicle. The high voltage battery is located behind the rear seat back with
service plug access through the trunk area.
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.RAG–5

2. Basic High Voltage Information
2-1 Battery Information
The Q70 HYBRID utilizes two batteries in order to supply both high and low voltage.
2-1.1 12-volt Battery• The Q70 HYBRID contains a conventional lead-acid12-volt battery.
• The 12-volt battery is located in the trunk, left of high voltage battery, concealed by trim cover.
• The 12-volt battery is charged by the high voltage battery through the DC/DC converter.
2-1.2 High Voltage Battery • The Q70 HYBRID contains a high voltage battery.
• The high voltage battery is mounted in the trunk areabehind the rear seat, enclosed in a metal case and
concealed by trim cover.
• The high voltage battery stores approximately 346 volts DC (400V max.) .
• A vent hose is provided to exhaust gasses outside the vehicle if necessary.
• An air vent is located on the rear parcel shelf for battery cooling.
The high voltage battery supplies power to the following: • High voltage harnesses
• DC/DC converter
• Traction motor inverter
• Traction motor
• Electric air conditioner compressor

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.

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 trans-
mission Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.

4-1.2 Shift Selector Lever Lock Release
If the 12-volt battery is low or discharged, the selector lever cannot be moved from the Park (P) position. If a
booster battery is not available, the selector lever lock can be manually released. To manually release the
selector lever lock, perform the following procedure:1. Push the ignition switch to the LOCK or OFF position.
2. Apply the parking brake.
3. Remove the shift lock cover (A) using a suitable tool.
4. Push down the shift lock (B) as shown in the illustration.
5. Push the selector lever button (C) and move the selectorlever to the Neutral (N) position (D) while holding down
the shift lock.
4-2 Tools Installed in the Vehicle
Tools:
The tools are located in the trunk area. • Raise the trunk floor cover (1) using the tab (A) .
• Remove jacking tools located inside the trunk as illustrated.
Spare tire:
The spare tire is located under the trunk floor cover. • Remove the clamp (2) holding the spare tire.

Perform vehicle towing by holding up drive (rear) wheels or on flatbed in order to prevent secondary
damage from voltage generated by the motor. In addition, turn the ignition switch OFF when towing the
vehicle. Refer to the following illustration:
It is also permissible to transport the Q70 facing rearward on a flatbed. If the vehicle cannot be
placed in Neutral, a P (Park) release procedure may be required. Refer to
4-1.2 Shift Selector
Lever Lock Release (RAG–22)
.
4-3.3 Use of Vehicle Equipped Hooks for Recovery Operations
Front: 1. Using a suitable tool wrapped with a protective cloth,remove the recovery hook cover from the bumper.
2. Securely install the recovery hook as illustrated. The recovery hook is located in the tool kit in the left side of
the trunk area.
Failure to securely install the recovery hook may result
in serious personal injury or death and/or vehicledamage.

5-2 Remove Service Plug
DANGER
•Do not remove the service plug without always wearing appropriate Personal
Protective Equipment (PPE) to help protect the responder from serious injury or death
by electrical shock.
•
Immediately cover the service plug socket with insulated tape. The high voltage
battery retains high voltage power even when the service plug is removed. To avoid
electric shock, NEVER touch the terminals inside the socket.
To avoid unintended reinstallation and risk of electrical shock and severe personal injury
or death, the service plug should be securely stored away from the vehicle while the vehicle
is in storage.
NOTE: Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, adjust
the steering column, adjust the seats, unlock the doors, etc. Once 12-volt battery is
disconnected, power controls will not operate.
1. Check the READY indicator (A) status in the instrument cluster. If it is on, the high voltage systemis active.
2. Place the shift selector in the Park (P) position.
3. Push the ignition switch (B) once to turn OFF the high voltage system. Then verify whether the READY indicator (A) is off.
If the READY indicator (A) does not turn off, continue to step 5 to open the trunk for 12-volt
battery negative cable access.
