10. Cover the service plug socket with insulated tape.
11. Wait approximately ten (10) minutes for complete discharge of the high voltage capacitor afterthe service plug has been removed.
12. Perform the dismantling operation. Refer to
6. Dismantling Information (DG–38).
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–19)], 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. DG–28

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 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.
DG–31

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 Q70 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–25)] and a sign put
on the vehicle indicating it is a hybrid vehicle with high voltage dangers. For example: DG–36

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 Q70 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–38

•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 contactingthem.
•
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 ordeath.
•
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) .
DG–39

6-2.2 Removal Procedure1. Discharge high voltage battery. Refer to
3-3 Discharge Procedures (DG–18).
2. Remove the service plug. Refer to
Alternate Procedure 2 (Remove Service Plug) (DG–25).
3. Insert an appropriate tool into the gap between the trunk lamp case and front trunk trim panel to remove the trunk lamp case.
4. Disconnect the trunk lamp harness connector.
5. Remove the trunk lid weather strip.
6. Remove the front trunk trim retainer clips.
7. Remove the front trunk trim panel (1) and remove the trunk floor trim panel (2) . 8.
Remove the battery inlet duct A (1) , DC/DC converter outlet duct (2) and battery outlet duct B (3) .
