Depending on type of fire (vehicle or
battery) use standard fire fighting
equipment (water or extinguisher) . To extinguish a fire.
Insulated tape Insulating To cover any damaged harnesses to
protect from and prevent electrical
shock. Tape should cover all bare or
damaged wire.
3-1.1 PPE (Personal Protective Equipment) Protective Wear Control
Perform an inspection of the PPE items before beginning work. Do not use any damaged PPE items.
3-1.2 Daily Inspection
This inspection is performed before and after use. The responder who will be using the items should
perform the inspection and check for deterioration and damage. • Insulated rubber gloves should be inspected for scratches, holes and tears. (Visual check and airleakage test)
• Insulated safety boots should be inspected for holes, damage, nails, metal pieces, wear or other problems on the soles. (Visual check)
• Insulated rubber sheet should be inspected for tears. (Visual check)

When arriving to an incident involving an INFINITI M35h HYBRID, the vehicle should be approached with
caution
and inspected for the level of damage. In addition to overall vehicle condition (location and severity
of body damage, air bag deployment, etc.) , the high-voltage system should be assessed specifically. The
locations of the high-voltage component parts are illustrated in this FRG. Refer to 2-2 High Voltage-Related
and

12V-Related Component Locations and Descriptions . Appropriate personal protective equipment
(PPE)

must always be worn when approaching a vehicle of unknown condition, as described in this FRG.
Situation 1) High voltage system intact, occupants can be accessed without extrication tools
The HV system can be shut down by following the procedure in this guide, while wearing appropriate PPE.
After HV system shut down, occupant assistance can begin immediately, and no wait period is necessary.
Situation 2) High voltage system intact, occupants cannot be accessed without extrication tools
The HV system can be shut down by following the procedure in this guide, while wearing appropriate PPE.
After HV system shut down, absolute care must be taken not to cut through or damage any HV system
wiring, battery or components within ten (10) minutes of HV system shut down, but occupant assistance
operations using extrication equipment can begin immediately. The locations of the HV components are
illustrated in this guide.
Situation 3) High-voltage (HV) system damaged
If there is any evidence that the HV system has been compromised (such as arcing/sparking, orange wiring
harnesses cut or damaged, HV component casings damaged, etc.) , the responder may still be at risk of
high voltage exposure. The vehicle must be approached with extreme caution prior to initiating any system
shut down procedures or rendering assistance to occupants. Appropriate PPE must always be worn as
described in this guide, and the ten (10) minute wait time must be observed after HV system shut down in
order to ensure the system is de-energized.
In rare situations where vehicle damage is very severe, HV system shut down procedures as described in
this guide may not work. In these instances extreme caution and appropriate risk management must be
followed to prevent shock or electrocution to the responder or occupant.
3-3.1 High Voltage System Shut-Down Procedure
Any of the following procedures can shut down the high voltage system. The first response operation should
only begin after shutting down the high voltage system. If the vehicle is heavily damaged, for example the
Li-ion battery is deformed, broken or cracked, appropriate PPE must always be used and the Li-ion battery
and high voltage components must not be touched. • Failure to properly shut down the high voltage system before the Emergency
Response
Procedures are performed will result in serious injury or death from
electrical shock. To prevent serious injury or death, DO NOT touch high voltage
harnesses or components without always wearing appropriate PPE.
• When contact with high voltage components or high voltage harnesses is
unavoidable,
or when there is risk of such contact, you must always wear appropriate
PPE.

• The vehicle contains parts that contain powerful magnets. If a person who is wearing
a
pacemaker or other medical device is close to these parts, the medical device may be
affected by the magnets. Such persons must not perform work on the vehicle.
• Be sure to check the READY indicator (1) in the instrument cluster, and verify that the READY indicator is off and the high voltage system is stopped.
• After the high voltage system is shut down, please wait for ten (10) minutes for complete discharge of the high voltage capacitor. While waiting, do not operate any vehicle
functions.
NOTE:
The high voltage full discharge takes ten (10) minutes, but after five (5) minutes the voltage
has dropped below 60V.
• Remove the 12V battery negative (-) terminal and wait for three (3) minutes to discharge the air bag capacitor. Even though the 12V battery negative (-) is disconnected, the
Supplemental Restraint System (SRS) air bag maintains voltage for three (3) minutes.
There is a possibility of sudden SRS air bag inflation due to harness short circuit or
damage and it may cause serious injuries.
• The 12V system will remain active even after the 12V battery negative (-) terminal is removed while the high voltage system is active. This is because the DC/DC converter will
not shut down and power will be supplied to the 12V system and high voltage system
continuously.
Before disconnecting the 12V battery terminal, if necessary, lower the windows, adjust the steering column,
adjust the seats, unlock the doors, open the trunk, etc. as required. Once the 12V battery is disconnected,
power controls will not operate.
Powering Down the High Voltage System
The high voltage system can be shut down with any 1 of the following procedures: • Turn OFF the power switch and disconnect the 12V battery. Refer to Primary Procedure.
•

Remove the fuse for the high voltage control system and disconnect the 12V battery. Refer to Alter-
nate

Procedure 1 .
•

Remove the service plug and disconnect the 12V battery. Refer to Alternate Procedure 2.20

Primary Procedure
NO
TE:
Before disconnecting the 12V battery terminal, if necessary, lower the windows, adjust the
steering column, adjust the seats, unlock the doors, etc. Once 12V 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 the next steps to open the trunk for 12V
battery negative cable access.
4. If possible, keep the INFINITI Intelligent Key™ at least 5 meters (16 feet) away from the vehicle (except as noted
below) .
5. Open the trunk using any of the following: a. push-button switch (C) on the lower LH side ofthe instrument panel.
b. trunk button (D) on the INFINITI Intelligent Key™ [press for longer than one (1) second].
c. trunk open request switch (E) (located above license plate)*.
d. with the mechanical key (F) housed inside the INFINITI Intelligent Key™.
* You must have the INFINITI Intelligent Key™ within approximately 1 meter (3 feet) range
of trunk request switch to use the trunk open request switch function. AAYIA0062ZZ

Alternate Procedure 2
• Do not remove the service plug without always wearing appropriate PPE to help
protect the responder from serious injury or death by electrical shock.
• Immediately cover the service plug socket with insulated tape. To avoid electric shock, DO NOT touch the terminals inside the socket. To avoid unintended reinstallation and risk of electrical shock and severe personal injury
or

death, the rescuer should carry the service plug on his/her person while work is in
progress.
NOTE: Before disconnecting the 12V battery terminal, if necessary, lower the windows, adjust the
steering column, adjust the seats, unlock the doors, etc. Once 12V 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.
