3-3.1 High-voltage System Shut-Down Procedure
Any
of the following procedures can shut down the high-voltage system. The first response operation
should only begin after shutting down the high-voltage system. If the vehicle is heavily damaged, for example
the high-voltage battery is deformed, broken or cracked, appropriate PPE must always be used and the
high-voltage battery and high-voltage components must not be touched. PPE must always be worn when
touching or working on high-voltage components. DANGER
• Failure to properly shut down the high-voltage system before the Emergency
Response
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) . Appropriate 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. • 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.
• Be sure to verify that the READY indicator is off (if possible) , and the high-voltage
system

is stopped.
• After the high-voltage system is shut down, please wait approximately ten (10) minutes for complete discharge of the high-voltage capacitor. While waiting, do not operate any
vehicle functions.
NOTE:
The high-voltage full discharge takes approximately ten (10) minutes.
• After shutting down the high-voltage system and removing the 12-volt battery negative (-) terminal, wait at least three (3) minutes to discharge the air bag capacitor. Even though
the 12-volt battery negative (-) is disconnected, the Supplemental Restraint System (SRS)
air bag maintains voltage at least three (3) minutes. During this time, there is a possibility
of sudden SRS air bag inflation due to harness short circuit or damage and it may cause
serious injuries.
• The 12V system will remain active even after the 12-volt battery negative (-) terminal is removed while the high-voltage system is active. This is because the charging system
will not shut down and power will be supplied to the 12V system and high-voltage system
continuously.
Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, adjust the steering
column, adjust the seats, unlock the doors, open the trunk, etc. as required. Once the 12-volt battery is
disconnected, power controls will not operate.

The high-voltage battery contains electrolyte solution. To avoid exposure to electrolyte

and serious personal injury, always wear appropriate

3-3.5 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.
If electrolyte solution leakage, or damage such as any problem with the high-voltage battery casing are
observed, first responders should attempt to neutralize the battery by applying a large volume of water to the
battery pack while wearing appropriate Personal Protective Equipment (PPE) . The neutralization process
helps stabilize the thermal condition of the battery pack but does not discharge the battery.
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.
3-3.6 Accessing the Occupants 1. Remove windowsa. Perform window removal the same as a normal vehicle.
2. Remove doors a. The doors are removable with hand tools or basic rescue tools such as electrical/hydraulicrescue tools. It may be easier to remove the doors by cutting door hinges.
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.
