battery INFINITI M HYBRID 2013 First responder´s Guide

• 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-

• 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

3-3.2 Water Submersion Damage level of submerged vehicle may not be apparent. Handling a submerged vehicle
without
appropriate 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.
• Always wear appropriate PPE and remove/drain water before removing the service
plug
when working on a vehicle after a fire or submersion to avoid electrical shock.
• If the vehicle is in the water, to avoid electrical shock do not touch the high voltage
components,
harnesses or service plug.
3-3.3 Vehicle Fire • Always utilize full PPE and self-contained breathing apparatus during fire fighting
operations.
Smoke from a M35h 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.
Fire attack should follow standard fire fighting practices.
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 and contains a high voltage system and warn all others.
During overhaul operations (late stage fire suppression process to examine for remaining sources of heat) ,
make sure the battery is fully cooled to avoid fire re-ignition. The battery could reignite if it is placed near fire.
To avoid possible electrical shock and serious personal injury, do not breach the Li-ion battery case.

3-3.4 Cutting the Vehicle Body
• Do not cut into high voltage related areas to avoid severe personal injury or death.
• Do not cut into the Li-ion battery to avoid severe personal injury or death.
• When removing parts, DO NOT touch the high voltage parts or the insides of the
exposed orange-colored high voltage cables to avoid severe personal injury or death. • Do not cut air bag parts to avoid unintended deployment of the air bags and the risk of
severe
personal injury or death.
If ten (10) minutes have passed since the rescuer shut down the high voltage system (refer to 3-3.1 High
V

oltage System Shut-Down Procedure ) , then the rescuer can cut the vehicle except for the Li-ion battery.If the rescuer cannot wait the full ten (10) minutes or shut down the high voltage system,
absolute

care must be taken to avoid cutting HV parts and appropriate PPE must always be
worn. DO NOT cut the Li-ion battery due to possible electrocution risk and electrolyte solution
leakage.
29

SRS Air Bag System Components Location
Avoid
cutting air bag system parts. However, the vehicle can be cut (except inflators) under the following
conditions: • The front, side and curtain air bags have deployed.
• At least three (3) minutes have passed after the 12V battery negative (-) cable has beendisconnected and the high voltage system has been shut down. AAYIA0012GB

3-3.5 Li-ion Battery Damage and Fluid Leaks
If
electrolyte solution leakage, or damage such as any problem with the Li-ion battery casing are observed,
first responders should attempt to neutralize the battery by applying a large volume of water to the battery
pack while wearing appropriate PPE. The neutralization process helps stabilize the thermal condition of the
battery pack but does not discharge the battery.
Li-ion Battery Electrolyte Solution Characteristics: • Clear in color
• Sweet odor
• Similar viscosity to water
• Skin irritant
• Eye irritant – If contact with eyes, rinse with plenty of water and see a doctor immediately.
• If electrolyte leak occurs, wear appropriate solvent resistant PPE and use a dry cloth to clean up thespilled electrolyte. Be sure to adequately ventilate the area.
• Highly flammable
• Electrolyte liquid or fumes that have come into contact with water vapors in the air will create an oxidized substance. This substance may irritate skin and eyes. In these cases, rinse with plenty of
water and see a doctor immediately.
• Electrolyte fumes (when inhaled) can cause respiratory irritation and acute intoxication. Move to fresh air and wash mouth with water. See a doctor immediately.
• Since the Li-ion battery is made up of many small sealed battery modules, electrolyte solution leakage should be minimal.
NOTE:
Other fluids in the vehicle (such as engine oil, washer fluid, brake fluid, coolant, etc.) are
the same as those in a conventional vehicle.
