Alternate Procedure 1 (Disconnect Underhood Fuse Panel)
NO
TE:
Before disconnecting the underhood fuse panel and the negative (-) battery cable, if
necessary, lower the windows, adjust the steering column, adjust the seats, unlock the
doors, etc. Once the underhood fuse panel and negative (-) battery cable are disconnected,
power controls will not operate.
1. Pull release handle (1) and pull up release lever (2) to open the hood.
2. Remove clips (A) and RH hood ledge cover (1) .NOTE: : Arrow in illustration depicts vehicle front
direction.

4. Disengage pawls (A) of underhood fuse panel cover and
remove underhood fuse panel cover (1) .
NOTE: : Arrow in illustration depicts vehicle front
direction.
5.

Pull underhood fuse panel (1) out by hand and
disconnect terminal (black) connector (A) .
NOTE: : Arrow in illustration depicts vehicle front
direction.
6.

If you cannot identify the connector, disconnect all
connectors on the underhood fuse panel. To avoid unintended reinstallation and risk of electrical shock and severe personal injury or
death,

the rescuer should cover the fuse box and connectors with insulated tape or remove
the fuse panel and carry on his/her person.
7. Open the trunk using any of the following:NOTE:
The trunk release power cancel switch must be in the
ON position in order for the trunk to be opened
using any of the methods below.
a. push-button switch on the lower LH side of theinstrument panel (ensure that the trunk release
power cancel switch is in the ON position) . A

* 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

4. If possible, keep the Infiniti Intelligent Key at least
5 meters (16 feet) away from the vehicle (except to open
the trunk as noted below) .
5. Open the trunk using any of the following: NOTE:
The trunk release power cancel switch must be in the
ON position in order for the trunk to be opened
using any of the methods below.
a. push-button switch on the lower LH side of theinstrument panel.

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. Wait approximately ten (10) minutes for complete discharge of the high-voltage capacitor
after the service plug has been removed.
11. Perform the first response action.
3-3.2 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.
• Always wear appropriate Personal Protective Equipment (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 NEVER touch the high-voltage
components,
harnesses or service plug. PPE must always be worn when touching or
working on high-voltage components. A

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.
