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 dismantler 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 dismantler 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

8. Open service plug access cover.
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. Cover the service plug socket with insulated tape.
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–42). AAYIA0204ZZ

3-4.2 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. 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 (10) minutes have passed since the dismantler shut down the high-voltage system
[refer to 3-4.1 High-voltage System Shut-Down Procedure (DG–21)], then the dismantler can cut the
vehicle
except for the high-voltage battery. DO NOT cut the high-voltage battery due to possible electrocution risk and electrolyte solution
leakage.

3-4.3 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.
3-4.4 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.
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.

5. Storing the Vehicle
The service plug must be removed to shut down the high-voltage system for storage.
Do
not store a vehicle inside a structure. Keep the vehicle away from other vehicles if the
high-voltage battery is severely damaged. There is possibility of delayed fire from a severely
damaged high-voltage battery.
If the Q50 HYBRID needs to be stored or left unattended, the high-voltage system must be shut down by
removing the service plug [refer to Alternate Procedure 2 (Remove Service Plug) (DG–28)] and a sign put
on
the vehicle indicating it is a hybrid vehicle with high-voltage dangers. For example:

6. Dismantling Information
Removal
or repair of the high-voltage battery requires special tools and specific training. Infiniti strongly
recommends that only certified INFINITI retailer technicians perform these operations.
6-1 Precautions for Handling High-voltage Battery DANGER
• Because Q50 HYBRID contains a high-voltage battery, there is the risk of electric
shock,
electric leakage, or similar accidents if the high-voltage components or vehicle
is handled incorrectly. Be sure to follow the correct work procedures when
performing inspection and dismantling.
• If it is necessary to touch any of the high-voltage harnesses or components you
must
always wear appropriate Personal Protective Equipment (PPE) and properly
shut-down the high-voltage system by removing the service plug.
• Be sure to always wear appropriate PPE before beginning work on the high-
voltage
system.
• Be sure to remove the service plug in order to shut-down the high-voltage system
before
performing inspection or dismantling of high-voltage system harnesses and
parts.
• If the vehicle is heavily damaged, for example the high-voltage battery is
deformed,
broken, or cracked; appropriate PPE must always be used at all times to
avoid electrical shock.
DG–42
Page 43 of 56
• The colors of the high-voltage harnesses and connectors are all orange. Orange
high-
voltage labels
are applied to the high-voltage battery and other high-voltage devices.
Do not touch the high-voltage battery or other high-voltage devices without always
wearing appropriate PPE.
• Clearly identify the persons responsible for high-voltage work and ensure that other
persons
do not touch the vehicle. When not working, cover high-voltage parts with an
insulating cover sheet and sign or similar item to prevent other persons from contacting
them.
• Be sure to put the removed service plug in your pocket and carry it with you so
another
person does not accidentally reinstall it while work is in progress.
• The high-voltage battery retains high-voltage at all times. Appropriate Personal
Protective
Equipment (PPE) must always be worn when touching or working on
high-voltage components to avoid risk of electrical shock and severe personal injury or
death.
• Immediately insulate disconnected high-voltage connectors and terminals with
insulated
tape.
• 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.
• Because this vehicle uses components that contain high-voltage and powerful
magnetism,
do not carry any metal products which may cause short circuits, or any
magnetic media (cash cards, credit cards, etc.) which may be damaged when working on
the vehicle.
• Keep removed high-voltage battery packs away from rain to avoid electric shock.
•
Do not heat removed battery packs higher than 158° F (70° C) . There is the possibility of a hybrid system malfunction occurring if the vehicle
is
changed to READY status while the service plug is removed.
