3-4.5 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 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 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.

4. Jump Starting
T
o start the hybrid system with a booster battery, the instructions and precautions below must be followed. If done incorrectly, jump starting can lead to a 12-volt battery explosion, resulting in severe
personal

injury or death. It could also damage your vehicle.
Jump starting provides power to the 12-volt system to allow the electrical systems to operate. The electrical
systems must be operating to allow the high-voltage battery to be charged. Jump starting does not charge
the high-voltage battery.
Discharged 12-volt battery may cause the following issues: • The instrument cluster cannot be displayed while the ignition switch is turned ON. (The hybridsystem cannot start.)
• Headlamps, horn, etc. are weak. • To avoid electrical shock, the high-voltage battery CANNOT be jump started.
•

Explosive hydrogen gas is always present in the vicinity of the 12-volt battery. Keep all
sparks and flames away from the 12-volt battery. Make sure the vent tube is mounted.
• Do not allow battery fluid to come into contact with eyes, skin, clothing or painted surfaces. Battery fluid is a corrosive sulfuric acid solution that can cause severe burns.
If the fluid comes into contact with anything, immediately flush the contacted area
with water.
• The booster battery must be rated at 12-volts. Use of an improperly rated battery can damage the vehicle.
• Whenever working on or near a 12-volt battery, always wear suitable eye protectors (for example, goggles or industrial safety spectacles) and remove rings, metal bands, or any
other jewelry. Do not lean over the 12-volt battery when jump starting.
• Do not attempt to jump start a frozen battery. It could explode and cause serious injury.
• QX60 HYBRID is equipped with an automatic cooling fan. It could come on at any time. Keep hands and other objects away from it.
• Always follow the jump starting instructions below. Failure to do so could result in damage to the charging system and cause personal injury.

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 • Because QX60 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. • 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.
