2-4 High Voltage Safety Measures
Circuit insulation The high voltage positive (+) and negative (-) circuits are insulatedfrom the metal chassis.
Reducing the risk of electrocution The high voltage components and harnesses have insulated cases or orange-colored coverings which provide insulation and easy identification.
The high voltage battery case is electrically connected to the vehicle
ground. This connection helps protect the vehicle occupants and
emergency responders from high voltage electrical shock.
Identification The high voltage components are labeled “WARNING” similar to the label shown below. All high voltage harnesses are coated in orange.
2-4.1 Warning Labels
To avoid serious injury, keep clear of engine parts at all times. Engine may start at any time if

the start switch and the READY lamps on the instrum ent panel are "ON". Make sure both
lamps are "OFF" before working in the engine compartment. See Owners Manual.

compartiment moteur. Le moteur peut démarrer a tout moment si le contacteur d' allumage
est a la position ON et que les témoins READY du ta bleau de bord sont allumés. Assurez-vous
que les deux témonins sont éteints avant de travailler dans le compartiment moteur.

3. Roadside Assistance Response Steps
•NEVER assume the Q70 HYBRID is shut OFF simply because it is quiet.
•
If the vehicle is damaged and you are not sure about the condition of the electric
vehicle system, contact first responders immediately. If the vehicle is damaged, the high
voltage system should be shut down by first responders while following the procedures in
the First Responders Guide and while wearing appropriate Personal Protective
Equipment (PPE) .
•
If the READYindicator is ON the high voltage system is active.
•
If possible, be sure to check the READYindicator on the instrument cluster and
verify that the READY
indicator is OFF and the high voltage system is stopped.
• Some of the under hood parts get hot and may cause serious burns. Use caution when working on or around these parts.

3-1 Preparation Items
Preparation Items Specification Purpose
PPE (personal protective equipment): Up to 1,000V For protection from high voltage electrical shock.
Insulated gloves
Insulated shoes
–
Safety shield
– To protect eyes when around
high voltage components andwiring.
Safety Glasses
Leather glovesMust be able to fasten tight
around the wrist (worn over
insulated gloves) . To protect insulated gloves.
Wrenches
Size:10mm To remove the 12-volt battery terminal bolt.
Solvent resistant protection gloves
Solvent resistant protection shoes – To utilize in the event of a high
voltage battery electrolytic
solution leak.
Absorbent pad The same pad used for internal combustion engine
fluids can be used.To absorb any high voltage
battery electrolytic solutionleakage.
Standard fire fighting equipment Standard fire fighting equipment.
Depending on type of fire
(vehicle or battery) use
standard fire fighting
equipment (water or
extinguisher) .To extinguish a fire.
Insulated tape Insulating To cover any damaged harnesses to protect from and
prevent electrical shock. Tape
should cover all bare or
damaged wire.
3-1.1 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.
RAG–15

3-1.2 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)
3-1.3 Insulated Tools
When performing work at locations where high voltage is applied (such as terminals) , use insulated tools
meeting 1,000V/300A specifications.
3-2 Indications the High Voltage System is ON
If the READY
indicator is ON, the high voltage system is active.
Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, unlock the doors, and
open the rear hatch as required. Once 12-volt battery is disconnected, power controls will not operate. RAG–16

3-3 Vehicle Immobilization and Stabilization
If possible, immobilize the vehicle by turning the 12-volt system OFF and stabilize it with a wheel chock(s) .
Stabilize the vehicle with wooden blocks or by removing air from the tires.
•To avoid electrical shock, do not put wooden blocks or wheel chock(s) under the
high-voltage components and harnesses as shown following.

3-4 Turning OFF the Ignition Switch1. Check the READY
indicator status. If it is ON, the high voltage system is active.
2. Press the ignition switch once to turn OFF the high voltage system. Then verify whether the READY
indicator is OFF.
3. If possible, keep the Infiniti Intelligent Key at least 5 meters (16 feet) away from the vehicle to prevent
accidentally turning ON the hybrid system while the
roadside assistance is in progress.
3-5 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.
•
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.
Only first responders wearing appropriate Personal Protective Equipment (PPE) should shut down the
vehicle. After shut down, standard towing/recovery procedures can be used. Refer to
4-3 Towing

3-6 Vehicle Fire
• Always utilize full Personal Protective Equipment (PPE) and self-contained breathingapparatus 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.
RAG–19

3-7 High Voltage Battery Damage And Fluid Leaks
The high-voltage 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 andsee 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 a hybrid vehicle
and contains a high voltage system and warn all others.
High Voltage Battery Electrolyte Solution Characteristics: • Clear in color
• Sweet odor
• Similar viscosity to water
• Since the high voltage 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.
