b. trunk button on the Infiniti Intelligent Key
[press for longer than one (1) second].
c. trunk open request switch (located above license plate)*.
* 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.
NOTE:
If the electrical release does not work, the
trunk will have to be forced open.
8. Open the 12-volt battery service access cover.
9. Disconnect negative (-) battery cable and cover it with insulated tape.
10. Wait approximately ten (10) minutes for complete discharge of the high-voltage capacitor
after the fuse panel and battery cable have been disconnected.
11. Perform the first response action. AAYIA0068ZZ

Alternate Procedure 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 rescuer should carry the service plug on his/her person while work is in
progress.
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

3-3.3 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.
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 high-voltage battery case.
3-3.4 Cutting the Vehicle Body DANGER
• Do not cut into high-voltage related areas to avoid severe personal injury or death.
• Do not cut into the high-voltage battery to avoid severe personal injury or death.
• When removing parts, NEVER touch the high-voltage parts or the insides of the
exposed
orange-colored high-voltage cables to avoid severe personal injury or
death. Appropriate Personal Protective Equipment (PPE) must always be worn when
touching or working on high-voltage components. Do not cut air bag parts to avoid unintended deployment of the air bags and the risk of
severe

personal injury or death.
If at least approximately ten (10) minutes have passed since the rescuer shut down the high-voltage
system (refer to 3-3.1 High-voltage System Shut-Down Procedure (FRG–21)) , then the rescuer can cut
the

vehicle except for the high-voltage battery. If the rescuer cannot wait approximately ten (10) minutes or shut down the high-voltage
system,

absolute care must be taken to avoid cutting HV parts and appropriate Personal
Protective Equipment (PPE) must always be worn.DO NOT cut the high-voltage battery due to
possible electrocution risk and electrolyte solution leakage.
FRG–32

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 12-volt battery negative (-) cable has beendisconnected and the high-voltage system has been shut down. = Inflators
(Peel
back plastic trim parts prior to cutting operation to confirm exact inflator location.) = Sensors

3-3.5 High-voltage Battery Damage And Fluid Leaks
The high-voltage battery contains electrolyte solution. To avoid exposure to electrolyte
solution
and serious personal injury, always wear appropriate solvent resistant Personal
Protective Equipment (PPE) and read the following precautions:
• Electrolyte solution is a skin irritant.
• Electrolyte solution is an 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 the spilled electrolyte. Be sure to adequately ventilate the area.
• Electrolyte solution is 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. AAYIA0190ZZ
FRG–36

If electrolyte solution leakage, or damage such as any problem with the high-voltage 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 Personal Protective Equipment (PPE) . The neutralization process
helps stabilize the thermal condition of the battery pack but does not discharge the battery.
High-voltage Battery Electrolyte Solution Characteristics: • Clear in color
• Sweet odor
• Similar viscosity to water
• Since the high-voltage battery is made up of many small sealed battery modules, electrolyte solutionleakage 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.
3-3.6 Accessing the Occupants 1. Remove windowsa. Perform window removal the same as a normal vehicle.
2. Remove doors a. The doors are removable with hand tools or basic rescue tools such as electrical/hydraulicrescue tools. It may be easier to remove the doors by cutting door hinges.
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.
3. Adjust steering wheel and front seat position (if necessary) as shown below: AAYIA0197ZZ
