INFINITI Q70 HYBRID 2018 First Responder´s

Before disconnecting the 12-volt 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 12-volt battery is
disconnected, power controls will not operate.

Primary Procedure
NO
TE:
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

Alternate Procedure 1 (Remove Fuses)
NO
TE:
Before removing any fuses, if necessary, lower the windows, adjust the steering column,
adjust the seats, unlock the doors, etc. Once fuses are removed, power controls will not
operate.
1. Pull release handle (A) to open the hood.
2. Remove fuse box cover (B) .
3. Remove 80A fuse (C) (black) .

injury
or death, the rescuer should carry the service plug on his/her person while work is in
progress. A A

5. Open the trunk. The trunk can be opened with the push-button switch (D) on the lower LH side of
the instrument panel or with the mechanical key (E) housed inside the Infiniti Intelligent Key.
6. Open the 12-volt battery service access cover (F) .
7. Disconnect negative (-) battery cable (G) and cover it with insulated tape.
8. Wait approximately ten (10) minutes for complete discharge of the high voltage capacitor after the fuse is pulled and battery cable has been disconnected.

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. 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 step 5 to open the trunk for 12-volt
battery negative cable access. TGAAYIA0015ZZ

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 of the 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. AAYIA0068ZZ

6. Open the 12-volt battery service access cover (G) .
7.
Disconnect negative (-) battery cable (H) and cover it with insulated tape.
8. Open service plug access cover (J) .
9. Remove the service plug (K) by pressing the locking tab (L) and rotating the handle (M) fully outward (N) . Using the handle, pull the service plug (P) completely out of its socket. HOLDC

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.
3-3.3 Vehicle Fire • Always utilize full Personal Protective Equipment (PPE) and self-contained breathing
apparatus
during fire fighting operations. Smoke from a Q70 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.
FRG–29

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 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–19)) , 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.
