1. About the INFINITI Q50 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

No. Component Location Description Traction Motor Inverter Engine compart-
ment (right rearside) 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.
Traction Motor Built-into the
transmission Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.
High voltageBattery
Trunk area
(behind rear seatback) 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 vehicle’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 (left side
behind trim panel) A lead-acid battery that supplies power to the
low voltage devices.
High VoltageHarnesses Trunk area (on high

3-5 Water Submersion
DANGER
Damage level of submerged vehicle may not be apparent. Handling a submerged
vehicle without appropriate Personal Protective Equipment (PPE) will result in serious
injury or death from electrical shock.
•The ignition switch of the submerged vehicle must be turned OFF first, if possible.
Then the vehicle must be completely out of the water and drained to avoid electrical shock.

If the vehicle is in the water, to avoid electrical shock NEVER touch the high voltage
components, harnesses or service plug. PPE must always be worn when touching or
working on high voltage components.
Only first responders wearing appropriate Personal Protective Equipment (PPE) should shut down the vehicle.
After shut down, standard towing/recovery procedures can be used. Refer to
4-3 Towing (RAG–25).
3-6 Vehicle Fire
• Always utilize full Personal Protective Equipment (PPE) and self-contained breathing apparatus during fire fighting operations. Smoke from a Q50 HYBRID vehicle fire is
similar to smoke from a conventional vehicle fire.
• In the case of extinguishing a fire with water, large amounts of water from a fire hydrant (if possible) must be used. DO NOT extinguish fire with a small amount of water.
In the event of a small fire, a Type ABC fire extinguisher may be used for an electrical fire
caused by wiring harnesses, electrical components, etc. or oil fire.
In case of vehicle fire, contact fire department immediately and extinguish the fire if possible. If you must
walk away from the vehicle, notify an appropriate responder or a rescue person of the fact that the vehicle is
a hybrid vehicle that contains a high voltage system and warn all others.

5. Storing the Vehicle
The service plug must be removed to shut down the high voltage system for storage.
Do not store a vehicle inside a structure. Keep the vehicle away from other vehicles if the
high voltage battery is severely damaged. There is possibility of delayed fire from a severely
damaged high voltage battery.
5-1 Danger Sign Example
If the Q50 HYBRID needs to be stored or left unattended, the high voltage system must be shut down by
removing the service plug [refer to
5-2 Remove Service Plug (RAG–34)] and a sign put on the vehicle
indicating it is a hybrid vehicle with high voltage dangers. For example: RAG–32

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. If possible, check the READY
indicator status in the instrument cluster. If it is on, the high
voltage system is active.
2. Place the shift selector in the Park (P) position.
3. Push the ignition switch once to turn OFF the high voltage system. Then verify whether the READY indicator
is off.
If the READY indicator does not turn off, continue to
step 5 to open the trunk for 12-volt battery negative
cable access.

8. Open service plug access cover.
9. Remove the service plug (A) by pulling the locking lever (B) , then pressing the locking tab (C)and rotating the handle (D) fully outward. Using the handle, pull the service plug (E) completely
out of its socket.
10. Cover the service plug socket with insulated tape.11. Wait approximately ten (10) minutes for complete discharge of the high voltage capacitor
after the service plug has been removed.
12. The vehicle is now ready for storage.
