3-2 Personal Protective Equipment (PPE) and Insulated Tools
3-2.1
Personal Protective Equipment (PPE) Protective Wear Control
Perform an inspection of the Personal Protective Equipment (PPE) items before beginning work. Do not use
any damaged PPE items.
3-2.2 Daily Inspection
This inspection is performed before and after use. The worker who will be using the items should perform
the inspection and check for deterioration and damage. • Insulated rubber gloves should be inspected for scratches, holes and tears. (Visual check and airleakage test)
• Insulated safety boots should be inspected for holes, damage, nails, metal pieces, wear or other problems on the soles. (Visual check)
• Insulated rubber sheet should be inspected for tears. (Visual check)
3-2.3 Insulated Tools
When performing work at locations where high voltage is applied (such as terminals) , use insulated tools
meeting 1,000V/300A specifications.
3-3 Discharge Procedures Do not perform this procedure if the high voltage battery is damaged. If you are unsure of
battery

damage, use extreme caution and always wear appropriate Personal Protective
Equipment (PPE) when working on high voltage components.
Li-ion battery discharging must take place before dismantling. Sufficient discharging can be achieved by
following these steps. 1. Place the shift selector into the Park (P) position
2. Apply the parking brake.
3. Set wheel chocks to ensure the vehicle is completely stopped.
4. Fasten the driver seat belt and close the driver door.
5. Apply foot brake and press the ignition switch to turn the system ON. Confirm READY indicator in instrument cluster turns ON.
a.
If the engine starts, leave the engine on until idling stops.
b. If the engine does NOT start, move on to next step.
6. Remove the shift lock cover (A) using a suitable tool.
7. Push down the shift lock (B) as shown in the illustration.
8. Push the shift selector button (C) and move the shift selector to Neutral (N) position (D) while holding down
the shift lock.
NOTE:
DO NOT press accelerator or foot brake after
moving the shift selector to the Neutral (N)
position. Otherwise Li-ion battery will start to be
charged. AAYIA0067ZZ
DG–18

9. Release the parking brake.
10. Turn ON electric devices such as headlamps, A/C (set to the coldest temperature) and rear
window defogger to discharge the high voltage battery. Allow approximately 15 minutes to
discharge. Discharge is complete when the READY indicator (B) (green) turns OFF and the
hybrid

system warning indicator (C) (orange) turns ON.
11. Press the ignition switch (A) to turn the system OFF.
Please contact following number if the vehicle could not be discharged. • 1-800-662-6200 (US) or 1-800-361-4792 (Canada)
• Hours of operation are 8am-5pm (Monday-Friday) Eastern, Central and Pacific time zones.
3-4 How to Handle a Damaged Vehicle
3-4.1 High Voltage System Shut-Down Procedure
Any of the following procedures can shut down the high voltage system. The dismantling operation can only
begin after shutting down the high voltage system. If the vehicle is heavily damaged, for example the Li-ion
battery is deformed, broken or cracked, appropriate PPE must always be used and the Li-ion battery and
high voltage components must not be touched. • Failure to properly shut down the high voltage system before the dismantling
procedures
are performed will result in serious injury or death from electrical shock. To
prevent serious injury or death, NEVER touch high voltage harnesses or components
without always wearing appropriate Personal Protective Equipment (PPE) . PPE
must always be worn when touching or working on high voltage components
• When contact with high voltage components or high voltage harnesses is
unavoidable,
or when there is risk of such contact, you must always wear appropriate
PPE. PPE must always be worn when touching or working on high voltage
components. AAYIA0033ZZ
DG–19

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.

4-1 Jump Starting Procedures
NO
TE:
Jumper cable connections under the hood of the Q70 HYBRID are not connected directly to
a battery. They are connected to chassis ground and a fuse box terminal. Refer to the
following instructions and the above illustration.
1. If the booster battery is in another vehicle (A) , position the two vehicles (A and B) to bring the12V battery and fuse box into close proximity to each other.
DO NOT allow the two vehicles to touch.
2. Apply the parking brake. Move the selector lever the P (Park) position. Switch off all unnecessary electrical systems (headlights, heater, air conditioner, etc.) .
3. Remove fuse box cover on the Q70 HYBRID and connect jumper cables in the sequence as illustrated () .
For models with a steering wheel lock mechanism:
If the 12V battery is disconnected or discharged, the steering wheel will lock and cannot be
turned. Supply power using jumper cables before pushing the ignition switch and disengaging
the steering lock. • Always connect positive (+) to positive (+) and negative (-) to body ground (for example,
as
illustrated) , not to the 12V battery.
• Make sure the jumper cables do not touch moving parts in the engine compartment and that the cable clamps do not contact any other metal.
• If the hybrid system does not start right away, push the ignition switch to the OFF position and wait ten (10) seconds before trying again.
4. Start the engine of the booster vehicle (A) and let it run for a few minutes.
5. Start the hybrid system of the vehicle being jump started (B) . AAYIA0069ZZ
DG–34

6. After starting the hybrid system, carefully disconnect the negative cable and then the positive
cable () .
7. Reinstall the fuse box cover.
NOTE:
If it is not possible to turn the hybrid system ON by following this procedure, contact
an INFINITI retailer immediately.
4-2 Shift Selector Lever Lock Release
If the 12V battery is low or discharged, the selector lever cannot be moved from the Park (P) position. If a booster bat-
tery is not available, the selector lever lock can be manually released. To manually release the selector lever lock, perform
the following procedure: 1. Push the ignition switch to the LOCK or OFF position.
2. Apply the parking brake.
3. Remove the shift lock cover (A) using a suitable tool.
4. Push down the shift lock (B) as shown in the illustration.
5. Push the selector lever button (C) and move the selectorlever to the Neutral (N) position (D) while holding down
the shift lock. AAYIA0067ZZ

16. Remove the mounting nut (A) and then disconnect the
harness from the fuse box on the left side of the trunk
room.
17. Disconnect the brake power supply backup unit harness connector (A) and remove the ground cable mounting
bolts (B) . : Vehicle front
18.

Disconnect the high voltage harness connector (A) and
harness connector (B) . : Vehicle front
Touching high voltage components without wearing
appropriate

Personal Protective Equipment (PPE) will
cause electrocution. Immediately protect the terminals of the disconnected
high

voltage harness connector socket using insulated
tape so that they are not exposed.
19. Disconnect the Li-ion battery cooling fan motor harness connector. JSCIA0279ZZ
