2014 INFINITI Q70 HYBRID Dismantling Guide

Alternate Procedure 2 (Remove Service Plug)
• Do not remove the service plug without always wearing appropriate Personal
Protective Equipment (PPE) to help protect the dismantler from serious injury or death
by electrical shock.
• Immediately cover the service plug socket with insulated tape. The Li-ion 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 dismantler 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.
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. AAYIA0062ZZ

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. Method

6. Open the 12V 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.
10. Cover the service plug socket with insulated tape. AAYIA0035ZZ

11. Wait approximately ten (10) minutes for complete discharge of the high voltage capacitor after
the service plug has been removed.
12. Perform the dismantling operation. Refer to 6. Dismantling Information (DG–38).
3-4.2

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, NEVER touch the high voltage parts or the insides of the
exposed
orange-colored high voltage cables to avoid severe personal injury or death.
Personal Protective Equipment (PPE) must always be worn when touching or
working on high voltage components. To avoid unintended reinstallation and risk of electrical shock and severe personal injury or
death,

the dismantler should carry the fuses or service plug on his/her person while work
is in progress. 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
3-4.1 High Voltage System Shut-Down Procedure (DG–19)) , then the dismantler can cut the vehicle
except

for the Li-ion battery. DO NOT cut the Li-ion battery due to possible electrocution risk and electrolyte solution
leakage.
DG–28

SRS Air Bag System Components Location
The
SRS air bag system must not be cut as there is a risk of short circuit and unintentional deployment of
the SRS 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.
1. Crash zone sensor 2. Supplemental front air bag

Bags) 3. Front seat-mounted side-

3-4.3 Water Submersion
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.
3-4.4 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.
In case of vehicle fire, contact fire department immediately and extinguish the fire if possible. 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 that contains a high voltage system and warn all others.

3-4.5 Li-ion Battery Damage and Fluid Leaks
The Li-ion 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.
In cases of battery case breach or electrolyte leakage, contact the fire department immediately. If you must
walk away from the vehicle, notify an appropriate responder of the fact that the vehicle is an electric car and
contains a high voltage system and warn all others.
Li-ion Battery Electrolyte Solution Characteristics: • Clear in color
• Sweet odor
• Similar viscosity to water
• Since the Li-ion 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.
